Cardiac rehabilitation (CR) is currently a crucial component in managing this condition. The aim was to assess the effects of cardiac rehabilitation on physical capacity of heart failure patients. Methods: This was a cross-sectional study conducted from February 1, 2021, to June 30, 2023. We included all patients with heart failure who underwent cardiac rehabilitation. Data analysis was performed using SPSS software version 24.0, with a significance level set at p Results: The study included 87 heart failure patients, with a male-to-female ratio of 1.8. Mean age was 57.10 years (±11.75). Coronary artery disease was the primary cause of heart failure, accounting for 75.9% of cases. Atrial fibrillation was present in 4.7% of cases. Following cardiac rehabilitation, Left Ventricular Ejection Fraction increased from 40.15% to 49.48% (p = 0.001). Resting heart rate decreased significantly from 81.4 bpm to 68.3 bpm (p = 0.000), and the number of METS increased from 4.3 to 6.57 (+56.8%;p = 0.000). The mean distance covered in the 6-minute walk test significantly increased from 337.8 meters to 522.7 meters (p = 0.000), reflecting a gain of 183.5 meters. Moreover, the increase in the number of METS was more pronounced in females (p = 0.001), non-obese individuals (p = 0.000), non-diabetics (p = 0.001), non-sedentary individuals (p = 0.000), and non-smokers (p = 0.000). The study reported a low readmissions rate of 2.2% and a mortality rate of 1.1%. Conclusion: Our study demonstrates that cardiac rehabilitation is beneficial for black African heart failure patients, resulting in significant improvements in symptoms, physical and capacity.展开更多

To build a pig model of congestive heart failure, a temporary artificial cardiac pacemaker was implanted in the pig’s body and paced at 220 beats to 240 beats per minute for 1 week. After the model of congestive heart failure was successfully set up, the frequency of the pacemaker was changed to 150 beats to 180 beats per minute to maintain the CHF model stable. Pigs were divided into three groups: The hr-GH group in which 0.5 mg/kg per day of hr-GH was administrated intramuscularly for 15 days, the injection control group in which an equal amount of physiological saline was injected intramuscularly, and a normal control group. The left ventricular diastolic end pressure was (10.60±2.41) mmHg in the hr-GH group, but (19.00±3.81) mmHg in the saline control group (P<0.01); Cardiac output was (1.86±0.13) L/min in the hr-GH group, but (1.56±0.18) L/min in the saline control group (P<0.05); Peripheral vascular resistance was (56.88±7.51) mmHg·(L/min) -1 in the hr-GH group, whereas (70.30±11.59) mmHg·(L/min) -1 in the saline control group (P<0.05); +dp/dt max was (2900±316.23) and (2280±286.36) in the hr-HG group and the saline control group respectively (P<0.05). The results show that hr-GH enhances myocardial contractility of CHF, and the CHF model built by a temporary artificial cardiac pacemaker at a high rate of stimulation is reasonable and applicable.展开更多

A total of 348 consecutive CHF patients who were admitted for cardiac resynchronization(CRT) and presented with low ejection fraction(EF) and wide QRS duration were enrolled in this study, along with 388 healthy individuals. Dyssynchrony was assessed based on filling time ratio(FT/RR), left ventricular pre-ejection delay(PED), interventricular mechanical delay(IVMD), longitudinal opposing wall delay(LOWD) and radial septal to posterior wall delay(RSPWD). Response to CRT was defined as a ≥15% increase in EF. The results showed that FT/RR was decreased while PED, IVMD, LOWD and RSPWD were increased in the CHF group compared with the control group(P〈0.01). In the CHF group, FT/RR was negatively correlated with the QRS duration, LV end-diastolic diameter(LVESd), LV end-diastolic volume(LVEDV) and LV end-systolic volume(LVESV)(P〈0.01), but positively with the LVEF(P〈0.01). Additionally, PED, IVMD, LOWD and RSPWD were positively correlated with the QRS duration, LVESd, LVEDV and LVESV(P〈0.01), but negatively with the LVEF(P〈0.01). The CHF group was divided into three subgroups according to the varying degrees of LVEF. FT/RR decreased successively from the LVEF-1 group to the LVEF-2 group to the LVEF-3 group, while the PED, IVMD, LOWD and RSPWD successively increased in the same order(P〈0.01). The CHF group was divided into three subgroups according to the varying degrees of QRS duration, and FT/RR decreased successively in a sequence from the QRS-1 group to the QRS-2 group to the QRS-3 group, while the PED, IVMD, LOWD and RSPWD successively increased in the same order(P〈0.01). Speckle tracking radial dyssynchrony ≥130 ms was predictive of an EF response in patients in QRS-1 group(78% sensitivity, 83% specificity), those in QRS-2 group(83% sensitivity, 77% specificity) and in QRS-3 group(89% sensitivity, 79% specificity). In conclusion, echocardiography is a convenient and sensitive method for evaluating cardiac dyssynchrony in patients with CHF.展开更多

Methods Rat models of I-IF were established by aortocaval fistula. Forty-eight rats were divided randomly into the HF (HF, n = 16), NRG-1β trealanent (NRG, n = 16), and sham operation (S, n = 16) group. The rats in the NRG group were administered NRG-1β (10 μg/kg per day) for 7 days via the tail vein, whereas the other groups were injected with the same doses of saline, Twelve weeks after operation, Connexin 43 (Cx43) expression in single myocytes obtained from the left ventricle was determined by immunocytochemistry. Total protein was extracted from frozen left ventricular tissues for immunoblotting assay, and the ultrastmcture of myocytes was observed by transmission electron microscopy. Results Compared with the HF group, the cardiac fimction of rats in the NRG group was markedly improved, irregular distribution and deceased Cx43 expression were relieved. The ultrastmcture of myocytes was seriously damaged in HF rats, and NRG-1β reduced these pathological damages. Conclusions Short-term NRG-1β treatment can rescue pump failure in experimental models of volume overload-induced HF, which is related to the recovery of GJs structure and the improvement of Cx43 expression.展开更多

The purpose of this study is to identify and validate predictors of SRs after CRT. Methods This study enrolled 201 patients who underwent CRT during the period from 2010 to 2014. Clinical and echocardiographic evaluations were conducted before CRT and 6 months after. Patients with a decrease in New York Heart Association (NYHA) fimctional class 〉 1, a decrease in left ventricular end-systolic volume (LVESV) ≥ 15%, and a final left ventricular ejection fraction (LVEF) ≥ 45% were classified as SRs. Results 29% of the 201 patients who underwent CRT were identified as SRs. At baseline, SRs had significantly smaller left atrial diameter (LAD), LVESV, left ventricular end-diastolic volume (LVEDV) and higher LVEF than the non-super-responders (non-SRs). The percentage of patients using angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARB) was higher in SRs than non-SRs. Most SRs had Biventricular (BiV) pacing percentage greater than 98% six months after CRT. In the multivariate logistic regression analysis, the independ- ent predictors of SRs were lower LVEDV [odd ratios (OR): 0.93; confidence intervals (CI): 0.90-0.97], use of ACEI/ARB (OR: 0.33; CI: 0.13~3.82) and BiV pacing percentage greater than 98% (OR: 0.29; CI: 0.16~.87). Conclusion Patients with a better compliance of ACEI/ARB and a less ectatic ventricular geometry before CRT tends to have a greater probability of becoming SRs. Higher percentage of BiV pacing is essential for becoming SRs.展开更多

Study Design and Setting: This randomized controlled trial recruited 70 patients who are in stage II CHF with ejection fraction (≤40%) from a Nigerian university teaching hospital. They were randomly assigned into Exercise Group (EG: n = 35) or Control Group (CG: n = 35). Physical function, activity of daily living (ADL), distance walked in six minutes and grip strength were assessed using a validated ADL questionnaire, six minute walk test and a hand dynamometer respectively. In addition to medication, EG underwent aerobic and upper extremity resistance exercises thrice weekly for eight weeks while CG used medications only. Data were analyzed using descriptive and inferential statistics. Alpha level was at p p > 0.05). Significant improvements were noticed at fourth week among participants’ ADL (30.0% ± 6.0%), 6MWD (321.7 ± 26.3 m) and VO<sub>2</sub> max (8.9 ± 0.4 mL/kg/min) variables within the exercise EG but no significant changes were observed in the CG (p > 0.05). Participants in EG demonstrated more significant improvements in ADL (15.0% ± 5.0%), 6MWD (406.0 ± 29.7 m) and VO<sub>2</sub> max (10.3 ± 0.5 mL/kg/min) (p p > 0.05). Conclusions: Cardiac rehabilitation exercise protocols involving self-paced walking, sit-to-stand and upper extremity dynamic strength training improved activity of daily living, walking and functional capacity in patients with stable chronic heart failure.展开更多

The nature of the protein defines the type of amyloidosis. Cardiac involvement is most often secondary to deposits of transthyretin and immunoglobulin light chains. Treatment depends on the type of amyloidosis. Cardiac light chain amyloidosis is a medical emergency. Aim: To highlight the importance of an early diagnosis of cardiac light chain amyloidosis. Case Presentation: We report the case of an 88-year-old hypertensive female patient with sustained atrial fibrillation and recurrent heart failure, in whom echocardiography showed concentric left ventricle hypertrophy with mildly reduced left ventricle ejection fraction (LVEF) to 45%. Bone scintigraphy was normal. Serum analysis showed increased lambda free light chains. Accessory salivary gland biopsy revealed weak Kappa light chain staining and clear overexpression of lambda light chain deposits. The diagnosis of stage 3B cardiac amyloidosis secondary to lambda light chain myeloma was made. After a multidisciplinary meeting, it was decided to start treatment with DARATUMUMAB + LENALIDOMIDE. Patient’s general condition deteriorated with the occurrence of febrile pancytopenia. Chemotherapy was stopped and management was limited to comfort care until the patient’s death. Conclusion: Cardiac light-chain amyloidosis must be diagnosed early as it can be rapidly fatal.展开更多

Here, we present a previously healthy 45-year-old man, who was admitted with pericardial effusion and symptoms of acute heart failure. CMR followed by targeted left ventricular endomyocardial biopsy(EMB) revealed the diagnosis of isolated SHD. The combined use of CMR and EMB was crucial in diagnosing SHD. Furthermore, this case report demonstrates the value of CMR for monitoring response to therapy and lesion healing.展开更多

Before treatment and after 3 months of treatment, cardiac color Doppler diasonograph was used to determine the levels of cardiac function parameters and ventricular remodeling parameters, and RIA method was used to determine the levels if peripheral blood neuroendocrine factors.Results: Before treatment, the differences in cardiac function, ventricular remodeling and neuroendocrine factor levels were not statistically significant between two groups of patients. After 3 months of treatment, cardiac function parameters LVEDd and LVESD levels of observation group were lower than those of control group while LVEF level was higher than that of control group, and ventricular remodeling parameters LVPWT, IVSS, PWD, PWS and LVMI levels were lower than those of control group;peripheral blood neuroendocrine factors NE, ALD, AngⅡ, ANP and ET contents of observation group were lower than those of control group.Conclusion:Trimetazidine combined with bisoprolol can optimize the cardiac function, suppress the ventricular remodeling process and regulate the neuroendocrine factor secretion in patients with chronic heart failure, and it contributes to the patients' overall optimization.展开更多

Implantable devices for heart failure have become standardized. Remote monitoring using cardiac devices has grown in popularity for medical efficiency and the early detection of abnormalities. Our first aim was to develop a tablet-PC-based nursing intervention program for patients requiring remote monitoring of implantable cardiac devices. The second purpose was to evaluate the efficacy of the program by using mixed-methods research. Methods: The study consisted of two phases. In phase 1, we designed a tablet-PC-based nursing intervention program, on the basis of a literature review and qualitative data collected via semi-structured interviews. In phase 2, we conducted a randomized controlled trial that served as a preliminary investigation of the program. The outcome measures were readmission, unexpected visits to the clinic for heart problems, quality of life, self-care behavior, and self-efficacy. After the study, we interviewed each participant about his or her experiences with the program. Interviews were audio recorded, coded, and thematically analyzed. Results: The 33 patients with heart failure were randomized into two groups as follows: 17 patients in the telenursing group and 16 in the control group. During 6 months of follow-up, the readmission for heart failure occurred in 11% of the intervention group and 18% of the control group. There were no statistically significant differences between the groups at any outcome measures. Three themes were extracted via qualitative analysis: “getting a sense of safety,” “triggering a health behavior change,” and “feeling like a burden.” Conclusion: No improvements in rates of rehospitalization or unexpected clinic visits were seen in the quantitative study. However, signs of behavior modification were seen in the qualitative study. This program has the possibility of improving patient outcomes.展开更多

Methods: Patients with refractory heart failure who were treated in People's Hospital Affiliated to Hubei University of Medicine between December 2014 and August 2016 were reviewed and divided into the control group (n=50) who received routine western medicine treatment and the observation group (n=41) who received Shenqi injection-assisted routine western medicine treatment. The differences in serum levels of cardiac function-related indexes and myocardial fibrosis-related indexes were compared between two groups of patients before and after treatment. Results: Before treatment, the differences in serum levels of cardiac function-related indexes and myocardial fibrosis-related indexes were not statistically significant between the two groups of patients. After 1 month and 3 months of treatment, serum cardiac function-related indexes NT-proBNP, Copeptin, GDF-15 and OPN levels of observation group were lower than those of control group;serum myocardial fibrosis-related indexes TGF-β1, CTGF, PⅠCP, CⅠTP and PⅢNP levels were lower than those of control group whereas APN levels were higher than that of control group. Conclusion: Routine western medicine treatment combined with adjuvant Shenqi injection therapy can effectively optimize the cardiac function and inhibit the myocardial fibrosis process in patients with refractory heart failure.展开更多

METHODS: A total of 140 CHF patients admitted to our hospital were randomly divided into combined group (Qiangxin Decoction and cardiac resynchronization, n = 70) and routine group (cardiac resynchronization, n = 70), and they were treated for 2 courses (16 weeks), with 8 weeks as a course. The improvement of heart function classification (HYHA) was observed before and after treatment, and the therapeutic effects were evaluated according to the improvement of heart function classification (markedly effective, effective, invalid, and worsening). The traditional Chinese medicine (TCM) diagnostic criteria was the main symptoms (0 to 6 points), secondary symptoms (0 to 3 points), tongue picture (0 to 1 point) and pulse condition (0 to 1 point), and the higher the score was, the more obvious the symptoms were. The left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction (LVEF) and cardiac output (CO) were observed and recorded according to the heart color ultrasound before and after treatment. And the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used to evaluate the life quality before and after treatment, and the highest score of the scale was 105 points. The higher the score was, the obvious the symptoms were, and the worse the life quality was. And the adverse reactions were recorded in the 2 groups. RESULTS: After the treatment, the total effective rate in the routine group was significantly lower than that in the combined group (75.71% vs . 94.30%), and there was statistically significant difference (P < 0.05). After the treatment, the TCM syndrome score in the routine group was higher than that in the combined group ((14.37±3.59) points vs.(10.53±3.11) points), and there was statistically significant difference (P < 0.05). After the treatment, the levels of LVEDD and LVESD in the routine group were higher than those in the combined group, and there were statistically significant differences (P < 0.05). The levels of LVEF and CO in the routine group were lower than those in the combined group, and there were statistically significant differences (P < 0.05). After the treatment, the score of MLHFQ scale in the routine group was higher than that in the combined group ((57.38±8.53) points vs.(46.39±7.14) points), and there was statistically significant difference (P < 0.05). CONCLUSION: Qiangxin Decoction combined with cardiac resynchronization therapy has good echocardiographic evaluation in patients with chronic heart failure.展开更多
文摘Chronic heart failure(HF)is a clinical syndrome with high morbidity and mor-tality worldwide.Cardiac rehabilitation(CR)is a medically supervised program designed to maintain or improve cardiovascular health of people living with HF,recommended by both American and European guidelines.A CR program con-sists of a multispecialty group including physicians,nurses,physiotherapists,trainers,nutritionists,and psychologists with the common purpose of improving functional capacity and quality of life of chronic HF patients.Physical activity,lifestyle,and psychological support are core components of a successful CR program.CR has been shown to be beneficial in all ejection fraction categories in HF and most patients,who are stable under medication,are capable of participating.An individualized exercise prescription should be developed on the basis of a baseline evaluation in all patients.The main modalities of exercise training are aerobic exercise and muscle strength training of different intensity and frequency.It is important to set the appropriate clinical outcomes from the beginning,in order to assess the effectiveness of a CR program.There are still significant limitations that prevent patients from participating in these programs and need to be solved.A significant limitation is the generally low quality of research in CR and the presence of negative trials,such as the rehabilitation after myocardial infarction trial,where comprehensive rehabilitation following myocardial infraction had no important effect on mortality,morbidity,risk factors,or health-related quality of life or activity.In the present editorial,we present all the updated knowledge and recommendations in CR programs.

文摘BACKGROUND Current treatments for chronic heart failure(CHF)are therapeutically ineffective.The optimization of treatments for this disease needs to be explored and analyzed.AIM To analyze the effect of using Luhong Formula in the cardiac rehabilitation of patients with CHF and its influence on cardiopulmonary function(CPF)and prognosis.METHODS In total,160 patients with CHF admitted between June 2022 and June 2023 were selected,including 75 receiving perindopril(control group)and 85 receiving Luhong Formula(research group).We conducted comparative analyses on the curative effects of traditional Chinese medicine(TCM)syndromes and cardiac function,CPF[oxygen consumption at the anaerobic threshold(VO2 AT)and at peak exercise(peak VO2)],echocardiographic indexes[left atrial volume index(LAVI),left ventricular muscle mass index(LVMI),left ventricular ejection fraction(LVEF)],and prognosis[major adverse cardiovascular events(MACEs)at 6 months follow-up].RESULTS The research group showed markedly higher curative effects of TCM syndromes and cardiac function than the control group.In addition,post-treatment VO2 AT,peak VO2,LVMI and LVEF in the research group were significantly higher,whereas LAVI was significantly lower,than those of the control group.Furthermore,fewer patients in the research group developed MACEs at the 6-month follow-up.CONCLUSION Luhong Formula is more therapeutically effective than perindopril for the cardiac rehabilitation of patients with CHF,specifically in enhancing CPF and prognosis.
文摘Background: Heart failure is a chronic and severe condition that often results from various heart diseases. Cardiac rehabilitation (CR) is currently a crucial component in managing this condition. The aim was to assess the effects of cardiac rehabilitation on physical capacity of heart failure patients. Methods: This was a cross-sectional study conducted from February 1, 2021, to June 30, 2023. We included all patients with heart failure who underwent cardiac rehabilitation. Data analysis was performed using SPSS software version 24.0, with a significance level set at p Results: The study included 87 heart failure patients, with a male-to-female ratio of 1.8. Mean age was 57.10 years (±11.75). Coronary artery disease was the primary cause of heart failure, accounting for 75.9% of cases. Atrial fibrillation was present in 4.7% of cases. Following cardiac rehabilitation, Left Ventricular Ejection Fraction increased from 40.15% to 49.48% (p = 0.001). Resting heart rate decreased significantly from 81.4 bpm to 68.3 bpm (p = 0.000), and the number of METS increased from 4.3 to 6.57 (+56.8%;p = 0.000). The mean distance covered in the 6-minute walk test significantly increased from 337.8 meters to 522.7 meters (p = 0.000), reflecting a gain of 183.5 meters. Moreover, the increase in the number of METS was more pronounced in females (p = 0.001), non-obese individuals (p = 0.000), non-diabetics (p = 0.001), non-sedentary individuals (p = 0.000), and non-smokers (p = 0.000). The study reported a low readmissions rate of 2.2% and a mortality rate of 1.1%. Conclusion: Our study demonstrates that cardiac rehabilitation is beneficial for black African heart failure patients, resulting in significant improvements in symptoms, physical and capacity.
文摘BACKGROUND Chronic heart failure(CHF)is a serious and prevalent condition characterized by impaired cardiac function and inflammation.Standard therapy for CHF has limitations,prompting the exploration of alternative treatments.Recombinant human brain natriuretic peptide(BNP)has emerged as a potential therapy,with evidence suggesting that it can improve cardiac function and reduce inflammation in patients with CHF.However,further research is required to determine the efficacy and safety of lyophilized recombinant human BNP in CHF patients and its impact on microinflammatory status.This study aimed to investigate the effects of lyophilized recombinant human BNP therapy on CHF patients’cardiac function and microinflammatory status.AIM To investigate the effects of freeze-dried recombinant human BNP therapy on cardiac function and microinflammatory status in patients with CHF.METHODS In total,102 CHF patients admitted to our hospital from January 2021 to January 2022 were randomly assigned to control and observation groups(n=51 patients/group).The control patients were treated with standard HF therapy for 3 d,whereas the observational patients were injected with the recombinant human BNP for 3 d.Clinical efficacy,inflammatory factor levels,myocardial damage,cardiac function before and after the treatment,and adverse reactions during treatment were compared between the two groups.RESULTS The overall clinical efficacy was higher in the observation group than in the control group.Compared with baseline,serum hypersensitive C-reactive protein,N-terminal proBNP,and troponin I level,and physical,emotional,social,and economic scores were lower in both groups after treatment,with greater reductions in levels and scores noted in the observation group than in the control group.The overall incidence of adverse reactions in the observation group was not significantly different compared with that in the control group(P>0.05).CONCLUSION Freeze-dried recombinant human BNP therapy can improve heart function and enhance microinflammatory status,thereby improving overall quality of life without any obvious side effects.This therapy is safe and reliable.
文摘The enhanced cardiac contractility effect of human recombinant growth hormone (hr-GH) on the congestive heart failure (CHF) was studied on the pig. To build a pig model of congestive heart failure, a temporary artificial cardiac pacemaker was implanted in the pig’s body and paced at 220 beats to 240 beats per minute for 1 week. After the model of congestive heart failure was successfully set up, the frequency of the pacemaker was changed to 150 beats to 180 beats per minute to maintain the CHF model stable. Pigs were divided into three groups: The hr-GH group in which 0.5 mg/kg per day of hr-GH was administrated intramuscularly for 15 days, the injection control group in which an equal amount of physiological saline was injected intramuscularly, and a normal control group. The left ventricular diastolic end pressure was (10.60±2.41) mmHg in the hr-GH group, but (19.00±3.81) mmHg in the saline control group (P<0.01); Cardiac output was (1.86±0.13) L/min in the hr-GH group, but (1.56±0.18) L/min in the saline control group (P<0.05); Peripheral vascular resistance was (56.88±7.51) mmHg·(L/min) -1 in the hr-GH group, whereas (70.30±11.59) mmHg·(L/min) -1 in the saline control group (P<0.05); +dp/dt max was (2900±316.23) and (2280±286.36) in the hr-HG group and the saline control group respectively (P<0.05). The results show that hr-GH enhances myocardial contractility of CHF, and the CHF model built by a temporary artificial cardiac pacemaker at a high rate of stimulation is reasonable and applicable.
文摘The present study investigated the application of echocardiography to evaluation of cardiac dyssynchrony in patients with congestive heart failure(CHF). A total of 348 consecutive CHF patients who were admitted for cardiac resynchronization(CRT) and presented with low ejection fraction(EF) and wide QRS duration were enrolled in this study, along with 388 healthy individuals. Dyssynchrony was assessed based on filling time ratio(FT/RR), left ventricular pre-ejection delay(PED), interventricular mechanical delay(IVMD), longitudinal opposing wall delay(LOWD) and radial septal to posterior wall delay(RSPWD). Response to CRT was defined as a ≥15% increase in EF. The results showed that FT/RR was decreased while PED, IVMD, LOWD and RSPWD were increased in the CHF group compared with the control group(P〈0.01). In the CHF group, FT/RR was negatively correlated with the QRS duration, LV end-diastolic diameter(LVESd), LV end-diastolic volume(LVEDV) and LV end-systolic volume(LVESV)(P〈0.01), but positively with the LVEF(P〈0.01). Additionally, PED, IVMD, LOWD and RSPWD were positively correlated with the QRS duration, LVESd, LVEDV and LVESV(P〈0.01), but negatively with the LVEF(P〈0.01). The CHF group was divided into three subgroups according to the varying degrees of LVEF. FT/RR decreased successively from the LVEF-1 group to the LVEF-2 group to the LVEF-3 group, while the PED, IVMD, LOWD and RSPWD successively increased in the same order(P〈0.01). The CHF group was divided into three subgroups according to the varying degrees of QRS duration, and FT/RR decreased successively in a sequence from the QRS-1 group to the QRS-2 group to the QRS-3 group, while the PED, IVMD, LOWD and RSPWD successively increased in the same order(P〈0.01). Speckle tracking radial dyssynchrony ≥130 ms was predictive of an EF response in patients in QRS-1 group(78% sensitivity, 83% specificity), those in QRS-2 group(83% sensitivity, 77% specificity) and in QRS-3 group(89% sensitivity, 79% specificity). In conclusion, echocardiography is a convenient and sensitive method for evaluating cardiac dyssynchrony in patients with CHF.
文摘Background:Little is known about exercise cardiac power(ECP),defined as the ratio of directly measured maximal oxygen uptake with peak systolic blood pressure during exercise,on heart failure(HF)risk.We examined the association of ECP and the risk of HF.Methods:This was a population-based cohort study of 2351 men from eastern Finland.The average time to follow-up was 25 years.Participants participated at baseline in an exercise stress test.A total of 313 cases of HF occurred.Results:Men with low ECP(<9.84 mL/mmHg,the lowest quartile)had a 2.37-fold(95%confidence interval(95%CI):1.68-3.35,p<0.0001)hazards ratio of HF as compared with men with high ECP(>13.92 mL/mmHg,the highest quartile),after adjusting for age.Low ECP was associated with a 1.96-fold risk(95%CI:1.38-2.78,p<0.001)of HF after additional adjustment for conventional risk factors.After further adjustment for left ventricular hypertrophy,the results hardly changed(hazards ratio=1.87,95%CI:1.31-2.66,p<0.001).One SD increase in ECP(3.16 mL/mmHg)was associated with a decreased risk of HF by 28%(95%CI:17%-37%).Conclusion:ECP provides a noninvasive and easily available measure from cardiopulmonary exercise tests in predicting HF.However,ECP did not provide additional value over maximal oxygen uptake.

文摘Heart failure represents the end point of a variety of cardiovascular diseases.It is a growing health burden and a leading cause of death worldwide.To date,limited treatment options exist for the treatment of heart failure,but exercise has been well-established as one of the few safe and effective interventions,leading to improved outcomes in patients.However,a lack of patient adherence remains a significant barrier in the implementation of exercise-based therapy for the treatment of heart failure.The insulin-like growth factor 1(IGF1)phosphoinositide 3-kinase(PI3K)pathway has been recognized as perhaps the most critical pathway for mediating exercisedinduced heart growth and protection.Here,we discuss how modulating activity of the IGF1PI3K pathway may be a valuable approach for the development of therapies that mimic the protective effects of exercise on the heart.We outline some of the promising approaches being investigated that utilize PI3K-based therapy for the treatment of heart failure.We discuss the implications for cardiac pathology and cardiotoxicity that arise in a setting of reduced PI3K activity.Finally,we discuss the use of animal models of cardiac health and disease,and genetic mice with increased or decreased cardiac PI3K activity for the discovery of novel drug targets and biomarkers of cardiovascular disease.

文摘Objective We performed experiments using Neuregulin-1β (NRG-1β) treatment to determine a mechanism for the protective role derived from its beneficial effects by remodeling gap junctions (GJs) during heart failure (HF). Methods Rat models of I-IF were established by aortocaval fistula. Forty-eight rats were divided randomly into the HF (HF, n = 16), NRG-1β trealanent (NRG, n = 16), and sham operation (S, n = 16) group. The rats in the NRG group were administered NRG-1β (10 μg/kg per day) for 7 days via the tail vein, whereas the other groups were injected with the same doses of saline, Twelve weeks after operation, Connexin 43 (Cx43) expression in single myocytes obtained from the left ventricle was determined by immunocytochemistry. Total protein was extracted from frozen left ventricular tissues for immunoblotting assay, and the ultrastmcture of myocytes was observed by transmission electron microscopy. Results Compared with the HF group, the cardiac fimction of rats in the NRG group was markedly improved, irregular distribution and deceased Cx43 expression were relieved. The ultrastmcture of myocytes was seriously damaged in HF rats, and NRG-1β reduced these pathological damages. Conclusions Short-term NRG-1β treatment can rescue pump failure in experimental models of volume overload-induced HF, which is related to the recovery of GJs structure and the improvement of Cx43 expression.
文摘Background Super-responders (SRs) are defined as patients who show crucial cardiac function improvement after cardiac resynchro- nization therapy (CRT). The purpose of this study is to identify and validate predictors of SRs after CRT. Methods This study enrolled 201 patients who underwent CRT during the period from 2010 to 2014. Clinical and echocardiographic evaluations were conducted before CRT and 6 months after. Patients with a decrease in New York Heart Association (NYHA) fimctional class 〉 1, a decrease in left ventricular end-systolic volume (LVESV) ≥ 15%, and a final left ventricular ejection fraction (LVEF) ≥ 45% were classified as SRs. Results 29% of the 201 patients who underwent CRT were identified as SRs. At baseline, SRs had significantly smaller left atrial diameter (LAD), LVESV, left ventricular end-diastolic volume (LVEDV) and higher LVEF than the non-super-responders (non-SRs). The percentage of patients using angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARB) was higher in SRs than non-SRs. Most SRs had Biventricular (BiV) pacing percentage greater than 98% six months after CRT. In the multivariate logistic regression analysis, the independ- ent predictors of SRs were lower LVEDV [odd ratios (OR): 0.93; confidence intervals (CI): 0.90-0.97], use of ACEI/ARB (OR: 0.33; CI: 0.13~3.82) and BiV pacing percentage greater than 98% (OR: 0.29; CI: 0.16~.87). Conclusion Patients with a better compliance of ACEI/ARB and a less ectatic ventricular geometry before CRT tends to have a greater probability of becoming SRs. Higher percentage of BiV pacing is essential for becoming SRs.
文摘Objective: This study investigated the effects of cardiac rehabilitation exercise protocols on physical function (PF) in patients with chronic heart failure (CHF). Study Design and Setting: This randomized controlled trial recruited 70 patients who are in stage II CHF with ejection fraction (≤40%) from a Nigerian university teaching hospital. They were randomly assigned into Exercise Group (EG: n = 35) or Control Group (CG: n = 35). Physical function, activity of daily living (ADL), distance walked in six minutes and grip strength were assessed using a validated ADL questionnaire, six minute walk test and a hand dynamometer respectively. In addition to medication, EG underwent aerobic and upper extremity resistance exercises thrice weekly for eight weeks while CG used medications only. Data were analyzed using descriptive and inferential statistics. Alpha level was at p p > 0.05). Significant improvements were noticed at fourth week among participants’ ADL (30.0% ± 6.0%), 6MWD (321.7 ± 26.3 m) and VO<sub>2</sub> max (8.9 ± 0.4 mL/kg/min) variables within the exercise EG but no significant changes were observed in the CG (p > 0.05). Participants in EG demonstrated more significant improvements in ADL (15.0% ± 5.0%), 6MWD (406.0 ± 29.7 m) and VO<sub>2</sub> max (10.3 ± 0.5 mL/kg/min) (p p > 0.05). Conclusions: Cardiac rehabilitation exercise protocols involving self-paced walking, sit-to-stand and upper extremity dynamic strength training improved activity of daily living, walking and functional capacity in patients with stable chronic heart failure.
文摘Background: Amyloidosis is a disease characterized by the deposition of fibrillar proteins in tissues. The nature of the protein defines the type of amyloidosis. Cardiac involvement is most often secondary to deposits of transthyretin and immunoglobulin light chains. Treatment depends on the type of amyloidosis. Cardiac light chain amyloidosis is a medical emergency. Aim: To highlight the importance of an early diagnosis of cardiac light chain amyloidosis. Case Presentation: We report the case of an 88-year-old hypertensive female patient with sustained atrial fibrillation and recurrent heart failure, in whom echocardiography showed concentric left ventricle hypertrophy with mildly reduced left ventricle ejection fraction (LVEF) to 45%. Bone scintigraphy was normal. Serum analysis showed increased lambda free light chains. Accessory salivary gland biopsy revealed weak Kappa light chain staining and clear overexpression of lambda light chain deposits. The diagnosis of stage 3B cardiac amyloidosis secondary to lambda light chain myeloma was made. After a multidisciplinary meeting, it was decided to start treatment with DARATUMUMAB + LENALIDOMIDE. Patient’s general condition deteriorated with the occurrence of febrile pancytopenia. Chemotherapy was stopped and management was limited to comfort care until the patient’s death. Conclusion: Cardiac light-chain amyloidosis must be diagnosed early as it can be rapidly fatal.
文摘This case report illustrates challenging aspects of diagnosis and treatment of isolated sarcoid heart disease(SHD) and the role of cardiovascular magnetic resonance(CMR) imaging. Here, we present a previously healthy 45-year-old man, who was admitted with pericardial effusion and symptoms of acute heart failure. CMR followed by targeted left ventricular endomyocardial biopsy(EMB) revealed the diagnosis of isolated SHD. The combined use of CMR and EMB was crucial in diagnosing SHD. Furthermore, this case report demonstrates the value of CMR for monitoring response to therapy and lesion healing.
文摘Objective:To study the effect of trimetazidine combined with bisoprolol on the cardiac function, ventricular remodeling and neuroendocrine factors in patients with chronic heart failure.Methods: A total of 52 patients with chronic heart failure who were treated in our hospital between January 2012 and November 2015 were collected and divided into the control group (n=26) who received bisoprolol therapy and the observation group (n=26) who received trimetazidine combined with bisoprolol therapy according to the double-blind randomized control method, and both groups were treated for 3 months. Before treatment and after 3 months of treatment, cardiac color Doppler diasonograph was used to determine the levels of cardiac function parameters and ventricular remodeling parameters, and RIA method was used to determine the levels if peripheral blood neuroendocrine factors.Results: Before treatment, the differences in cardiac function, ventricular remodeling and neuroendocrine factor levels were not statistically significant between two groups of patients. After 3 months of treatment, cardiac function parameters LVEDd and LVESD levels of observation group were lower than those of control group while LVEF level was higher than that of control group, and ventricular remodeling parameters LVPWT, IVSS, PWD, PWS and LVMI levels were lower than those of control group;peripheral blood neuroendocrine factors NE, ALD, AngⅡ, ANP and ET contents of observation group were lower than those of control group.Conclusion:Trimetazidine combined with bisoprolol can optimize the cardiac function, suppress the ventricular remodeling process and regulate the neuroendocrine factor secretion in patients with chronic heart failure, and it contributes to the patients' overall optimization.
文摘A 67-year-old man with a history of a prior cardiac arrest with ventricular fibrillation(VF)due to myocardial infarction underwent phase I(inpatient)and II(outpatient)cardiac rehabilitation(CR)exercise training.On the 33th CR session,15 min after the start of exercise training,the patient had syncope with evidence of a polymorphic and wide QRS complex tachycardia on electrocardiogram(ECG)monitoring.The initiation of a polymorphic ventricular tachycardia was evidenced by the coupled premature ventricular complex observed in the ECG monitoring screen(Figure 1).
文摘Objective Overactivation of sympathetic nerve system is one of the main mechanism in post-MI myocardial remodeling even after early reperfusion, it eventually leads to heart failure. And renal denervation which targets at renal sympathetic nerves may have beneficial effects on cardiac remodeling. So we perform an experiment aiming to investigate the effect of RDN on cardiac remodeling and function.
文摘Background: With the rapid aging of society, the number of patients with heart failure has also increased. Implantable devices for heart failure have become standardized. Remote monitoring using cardiac devices has grown in popularity for medical efficiency and the early detection of abnormalities. Our first aim was to develop a tablet-PC-based nursing intervention program for patients requiring remote monitoring of implantable cardiac devices. The second purpose was to evaluate the efficacy of the program by using mixed-methods research. Methods: The study consisted of two phases. In phase 1, we designed a tablet-PC-based nursing intervention program, on the basis of a literature review and qualitative data collected via semi-structured interviews. In phase 2, we conducted a randomized controlled trial that served as a preliminary investigation of the program. The outcome measures were readmission, unexpected visits to the clinic for heart problems, quality of life, self-care behavior, and self-efficacy. After the study, we interviewed each participant about his or her experiences with the program. Interviews were audio recorded, coded, and thematically analyzed. Results: The 33 patients with heart failure were randomized into two groups as follows: 17 patients in the telenursing group and 16 in the control group. During 6 months of follow-up, the readmission for heart failure occurred in 11% of the intervention group and 18% of the control group. There were no statistically significant differences between the groups at any outcome measures. Three themes were extracted via qualitative analysis: “getting a sense of safety,” “triggering a health behavior change,” and “feeling like a burden.” Conclusion: No improvements in rates of rehospitalization or unexpected clinic visits were seen in the quantitative study. However, signs of behavior modification were seen in the qualitative study. This program has the possibility of improving patient outcomes.
文摘Objective: To explore the effect of adjuvant Shenqi injection therapy on cardiac function and myocardial fibrosis in patients with refractory heart failure. Methods: Patients with refractory heart failure who were treated in People's Hospital Affiliated to Hubei University of Medicine between December 2014 and August 2016 were reviewed and divided into the control group (n=50) who received routine western medicine treatment and the observation group (n=41) who received Shenqi injection-assisted routine western medicine treatment. The differences in serum levels of cardiac function-related indexes and myocardial fibrosis-related indexes were compared between two groups of patients before and after treatment. Results: Before treatment, the differences in serum levels of cardiac function-related indexes and myocardial fibrosis-related indexes were not statistically significant between the two groups of patients. After 1 month and 3 months of treatment, serum cardiac function-related indexes NT-proBNP, Copeptin, GDF-15 and OPN levels of observation group were lower than those of control group;serum myocardial fibrosis-related indexes TGF-β1, CTGF, PⅠCP, CⅠTP and PⅢNP levels were lower than those of control group whereas APN levels were higher than that of control group. Conclusion: Routine western medicine treatment combined with adjuvant Shenqi injection therapy can effectively optimize the cardiac function and inhibit the myocardial fibrosis process in patients with refractory heart failure.
文摘OBJECTIVE: To explore the echocardiographic evaluation of patients with chronic heart failure (CHF) after Qiangxin Decoction combined with cardiac resynchronization therapy. METHODS: A total of 140 CHF patients admitted to our hospital were randomly divided into combined group (Qiangxin Decoction and cardiac resynchronization, n = 70) and routine group (cardiac resynchronization, n = 70), and they were treated for 2 courses (16 weeks), with 8 weeks as a course. The improvement of heart function classification (HYHA) was observed before and after treatment, and the therapeutic effects were evaluated according to the improvement of heart function classification (markedly effective, effective, invalid, and worsening). The traditional Chinese medicine (TCM) diagnostic criteria was the main symptoms (0 to 6 points), secondary symptoms (0 to 3 points), tongue picture (0 to 1 point) and pulse condition (0 to 1 point), and the higher the score was, the more obvious the symptoms were. The left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction (LVEF) and cardiac output (CO) were observed and recorded according to the heart color ultrasound before and after treatment. And the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used to evaluate the life quality before and after treatment, and the highest score of the scale was 105 points. The higher the score was, the obvious the symptoms were, and the worse the life quality was. And the adverse reactions were recorded in the 2 groups. RESULTS: After the treatment, the total effective rate in the routine group was significantly lower than that in the combined group (75.71% vs . 94.30%), and there was statistically significant difference (P < 0.05). After the treatment, the TCM syndrome score in the routine group was higher than that in the combined group ((14.37±3.59) points vs.(10.53±3.11) points), and there was statistically significant difference (P < 0.05). After the treatment, the levels of LVEDD and LVESD in the routine group were higher than those in the combined group, and there were statistically significant differences (P < 0.05). The levels of LVEF and CO in the routine group were lower than those in the combined group, and there were statistically significant differences (P < 0.05). After the treatment, the score of MLHFQ scale in the routine group was higher than that in the combined group ((57.38±8.53) points vs.(46.39±7.14) points), and there was statistically significant difference (P < 0.05). CONCLUSION: Qiangxin Decoction combined with cardiac resynchronization therapy has good echocardiographic evaluation in patients with chronic heart failure.
