Twin pregnancy with sudden heart failure and pulmonary hypertension after atrial septal defect repair: A case report

BACKGROUND Pulmonary arterial hypertension(PAH)in pregnancy is one of the major obstetric complications and is considered a contraindication to pregnancy as it is classified as a class IV risk in the revised risk classification of pregnancy by the World Health Organisation.Pregnancy,with its adaptive and expectant mechanical and hormonal changes,negatively affects the cardiopulmonary circulation in pregnant women.Do patients with repaired simple congenital heart disease(CHD)develop other pulmonary and cardiac complications during pregnancy?Can pregnant women with sudden pulmonary hypertension be treated and managed in time?In this paper,we present a case of a 39-year-old woman who underwent cesarean section at 33 wk'gestation and developed PAH secondary to repaired simple CHD.Our research began by a PubMed search for"pulmonary hypertension"and"pregnancy"and"CHD"case reports.Three cases were selected to review PAH in pregnancy after correction of CHD defects.These studies were reviewed,coupled with our own clinical experience.CASE SUMMARY Herein,a case involving a woman who underwent atrial septal defect repair at the age of 34,became pregnant five years later,and had a sudden onset of PAH and right heart failure secondary to symptoms of acute peripheral edema in the third trimester of her pregnancy.As a result,the patient underwent a cesarean section and gave birth to healthy twins.Within three days after cesarean delivery,her cardiac function deteriorated as the pulmonary artery pressure increased.Effec-tive postpartum management,including diuresis,significant oxygen uptake,vasodilators,capacity and anticoagulants management,led to improvements in cardiac function and oxygenation.The patient was discharged from hospital with a stable recovery and transferred to local hospitals for further PAH treatment.CONCLUSION This case served as a reminder to obstetricians of the importance of pregnancy after repair of CHD.It is crucial for patients with CHD to receive early correction.It suggests doctors should not ignore edema of twin pregnancy.Also,it provides a reference for the further standardization of antenatal,in-trapartum and postpartum management for patients with CHD worldwide.

Hemodynamic monitoring in heart failure and pulmonary hypertension: From analog tracings to the digital age

Hemodynamic monitoring has long formed the cornerstone of heart failure(HF) and pulmonary hypertension diagnosis and management. We review the long history of invasive hemodynamic monitors initially using pulmonary artery(PA) pressure catheters in the hospital setting, to evaluating the utility of a number of implantable devices that can allow for ambulatory determination of intracardiac pressures. Although the use of indwelling PA catheters has fallen out of favor in a number of settings, implantable devices have afforded clinicians an opportunity for objective determination of a patient's volume status and pulmonary pressures. Some devices, such as the CardioM EMS and thoracic impedance monitors present as part of implantable cardiac defibrillators, are supported by a body of evidence which show the potential to reduce HF related morbidity and have received regulatory approval, whereas other devices have failed to show benefit and, in some cases, harm. Clearly these devices can convey a considerable amount of information and clinicians should start to familiarize themselves with their use and expect further development and refinement in the future.

From hypertension to heart failure

Hypertension is an increasing health problem worldwide especially among the elderly.Its therapeutical importance is indicated by the caused organ damages like hypertensive heart disease(HHD) and heart failure with the subsequent higher morbidity and mortality in the population.In HHD ventricular hypertrophy develops as a compensatory mechanism for pressure overload but as the left ventricular compliance decreases,the process can transform into heart failure with firstly preserved and then into reduced ejection fraction(HFp EF,HFr EF).The main characteristics of underlying mechanisms involve cardiomyocyte growth,vessel changes,increased collagen production in all of which several mechanical stress induced neurohumoral agents,signal transduction pathways are involved.According to the new ESC and AHA guidelines five main groups of antihypertensive agents can be applied for decreasing blood pressure and for the prevention of organ damages.Occasionally,patients are not able to tolerate antihypertensive medication because of side effects,drug intolerance or interactions thus it is more difficult to reach the target blood pressure values.Therefore there are several efforts to complete the existing therapeutical possibilities against the development of organ damages like inhibition of Rho/ROCK pathway(e.g.,statins),regulation of ROS formation,influence on mitochondrial biogenesis and enhancing recombinant adenovirus hepatocyte growth factor gene.Hypertension induced oxidative stress causes DNA breaks producing the activation of nuclear poly(ADP-ribose) polymerase-1(PARP) enzyme that leads to energy depletion and unfavorable modulation of different kinase cascades.PARP activation promotes the development of HHD,and its transition to heart failure.Therefore inhibition of PARP-enzyme offers another new therapeutical approach among hypertensive patients.The purpose of this review is to give a comprehensive summary about the most significant mechanisms in HHD and an insight into new potential therapies.

Enalapril Combined with Hydrochlorothiazide and Indapamide in the Treatment of Hypertension with Heart Failure

Objecrive:To explore the effect of enalapril combined with hydroch1orothiazide and indapamide on hypertension and heart failure.Methods:8o patients with hypertension and heart failure admitted to our hospitail from January 2019 to January 2020 were selected as the research subjects,and they were divided into two groups with random number table method,40 cases each.The control group was given conventional treatment regimens,including enalapril and hydroch1orothiazide;the observation group replaced hydrochlorothiazide with indapamide based on the above therapies.The efficacy and systolic blood pressure,diastolic blood pressure and left heart ejection fraction(LVEF)of the two groups were compared.Results:After treatment,the effective rate of the observation group was 92.50%(37/40)higher than that of the control group 75.00%(30/40).The systolic and diastolic blood pressure were lower than those of the control group,and the LVEF was higher than that of the control group.The difference was statistically significant(P<0.05).Conclusion:Enalapril combined with indapamide is effective in the treatment of hypertension with heart failure,which can help 1ower blood pressure,reduce heart 1oad,increase cardiac output,reverse ventricular remodeling,and delay disease progression.

Hypertension and Heart Failure as Predictors of Mortality in an Adult Congenital Heart Defect Population

Early intervention to prevent premature mortality is vital for adults with congenital heart defects(CHD).Anatomic complexity and comorbid conditions are thought to contribute to CHD mortality.Since hypertension(HTN)and heart failure(HF)are the comorbid conditions among the most prevalent causes of death in the United States,and commonly accompany CHD,it is crucial to evaluate whether they are reliable predictors of mortality for adults with CHD(ACHD)independent of anatomic CHD complexity.A retrospective cross-sectional analysis of ACHD,aged 18–64,with concomitant HTN and/or HF and at least one health care encounter during 2008–2010 were assessed.Of 5,397 ACHD patients(18.3%HTN without HF,4.4%HF without HTN,8.3%with both),3.0%died(n=163)during the study period.Overall,the sample was 45.1%white,61.4%female,and 29.0%had a complex CHD.Among those who died,23.3%had HTN without HF,17.2%had HF without HTN,and 42.3%had both.Crude analyses revealed that older age,male gender,black race,and having public health insurance were associated with increased mortality during the three-year study period compared to ACHD patients who were younger,female gender,white race,and covered by private health insurance.ACHD patients diagnosed with non-complex CHD lesions(i.e.,shunts,valves,or shunts+valves)were at greater risk of dying compared to those with severe complex CHDs.When CHD type was assessed separately,those with valve lesions were more likely to die compared to those with complex CHD lesions.After adjustment for age,gender,race,insurance and CHD complexity,ACHD patients with HF,with or without HTN,were equally likely to die during the study period.However,ACHD patients with HF,without or without HTN,who had valve defects were more likely to die during the three-year study period compared to patients with complex CHDs.

Risk Stratification and Prognosis of Pulmonary Arterial Hypertension Associated with Congenital Heart Disease

Background:Current guidelines for managing pulmonary arterial hypertension(PAH)recommend a risk strati-fication approach.However,the applicability and accuracy of these strategies for PAH associated with congenital heart disease(PAH-CHD)require further validation.This study aims to validate the reliability and predictive accuracy of a simplified stratification strategy for PAH-CHD patients over a three-year follow-up.Additionally,new prognostic variables are identified and novel risk stratification methods are developed for assessing and managing PAH-CHD patients.Methods:This retrospective study included 126 PAH-CHD patients.Clinical and biochemical variables across risk groups were assessed using Kruskal-Wallis and Fisher’s exact tests.Indepen-dent risk factors were identified using ordered logistic regression,while Kaplan-Meier and Cox proportional hazards regression analyses evaluated their impact on all-cause mortality.A new stratification model for the PAH-CHD population was constructed based on these analyses.Results:Significant survival differences across stratified risk groups were observed(p<0.001),validating the effectiveness of the simplified risk stratification method in PAH-CHD patients.Prothrombin activity was a strong independent predictor of adverse outcomes of PAH-CHD patients(Hazard ratio 0.95,p<0.001,C-index 0.70).A model combining N-terminal pro-brain natriuretic peptide,prothrombin activity,albumin,and right atrial area achieved an area under the curve of 0.89 and a C-index of 0.85.Conclusions:The simplified risk stratification method is applicable to PAH-CHD patients.Prothrombin activity is a strong independent predictor of adverse outcomes.A comprehensive risk stratification approach,incorporating both established and novel biomarkers,enhances accessibility and offers predictive efficacy during follow-up for PAH-CHD patients,comparable to established models.

Effect of Cardiac Rehabilitation on Physical Capacity of Heart Failure Patients in Senegal

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.

Congestive Heart Failure: Treatment of Symptoms or Causes

This paper is based on the author’s 20+ years of experience treating patients with congestive heart failure (CHF) as a cardiologist. In the 20+ years, 64 patients were treated, including both with reduced and preserved left ventricular function. Most patients had a 4 - 5 days hospitalization in their first admission with one readmission (1.6%) over seven years. This paper will help us understand the physiology and pathophysiology of congestive heart failure, especially how to use beta blockers and diuretics. It will shorten the length of hospitalization and lower the readmission rate and cost of CHF treatment. This paper will help us to open another research direction for CHF.

Predictive Effect of CA125 on Adverse Cardiovascular Events in Patients with Chronic Heart Failure

Objective: To study the expression of CA125 in the serum of patients with CHF and the relationship between CA125 level and the occurrence of adverse cardiovascular events. Methods: The clinical data of 132 patients with CHF admitted to Shizuishan Second People’s Hospital from January 2023 to December 2023 were collected and divided into heart function II group, heart function III group, heart function IV group according to cardiac function. 44 healthy subjects who underwent physical examination during the same period were selected as the control group. The clinical data of CA125, NT-proBNP, echocardiography and other clinical data of the four groups were compared, and the incidence of major adverse cardiovascular events was followed up for 12 months. Results: Compared with the control group, the CA125 level in the CHF group was significantly increased (P Conclusion: Serum CA125 level is related to the cardiac function level in CHF patients and increases with the deterioration of cardiac function. The increase of the index is related to the mortality rate and re-hospitalization rate, suggesting that CA125 can be used as an indicator to reflect the severity of heart failure and prognosis monitoring.

BACKGROUND The specific benefits of Yangxinshi tablet(YXST)in the treating chronic heart failure(CHF)remain uncertain.AIM To systematically evaluate the efficacy and safety of YXST in the treatment of CHF.METHODS Randomized controlled trials(RCTs)investigating YXST for CHF treatment were retrieved from eight public databases up to November 2023.Meta-analyses of the included clinical studies were conducted using Review Manager 5.3.RESULTS Twenty RCTs and 1845 patients were included.The meta-analysis results showed that the YXST combination group,compared to the conventional drug group,significantly increased the clinical efficacy rate by 23%[relative risk(RR)=1.23,95%CI:1.17-1.29],(P<0.00001),left ventricular ejection fraction by 6.69%[mean difference(MD)=6.69,95%CI:4.42-8.95,P<0.00001]and 6-min walk test by 49.82 m(MD=49.82,95%C:38.84-60.80,P<0.00001),and reduced N-terminal pro-Btype natriuretic peptide by 1.03 ng/L[standardized MD(SMD)=-1.03,95%CI:-1.32 to-0.74,P<0.00001],brain natriuretic peptide by 80.95 ng/L(MD=-80.95,95%CI:-143.31 to-18.59,P=0.01),left ventricular end-diastolic diameter by 3.92 mm(MD=-3.92,95%CI:-5.06 to-2.78,P<0.00001),and left ventricular endsystolic diameter by 4.34 mm(MD=-4.34,95%CI:-6.22 to-2.47,P<0.00001).Regarding safety,neither group reported any serious adverse events during treatment(RR=0.54,95%CI:0.15-1.90,P=0.33).In addition,Egger's test results indicated no significant publication bias(P=0.557).CONCLUSION YXST effectively improves clinical symptoms and cardiac function in patients with CHF while maintaining a favorable safety profile,suggesting its potential as a therapeutic strategy for CHF.

Effect of Luhong formula on the cardiac rehabilitation of patients with chronic heart failure

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.

Assessing myocardial indices and inflammatory factors to determine anxiety and depression severity in patients with chronic heart failure

BACKGROUND Patients with chronic heart failure(CHF)have a progressive disease that is associated with poor quality of life and high mortality.Many patients experience anxiety and depression(A&D)symptoms,which can further accelerate disease progression.We hypothesized that indicators of myocardial function and inflammatory stress may reflect the severity of A&D symptoms in patients with CHF.Changes in these biomarkers could potentially predict whether A&D symptoms will deteriorate further in these individuals.AIM To measure changes in cardiac and inflammatory markers in patients with CHF to determine A&D severity and predict outcomes.METHODS We retrospectively analyzed 233 patients with CHF treated at the Jingzhou Hospital,Yangtze University between 2018-2022 and grouped them according to Self-Rating Anxiety Scale(SAS)and Self-Rating Depression Scale(SDS)scores.We compared clinical data in the no-A&D,mild-A&D,moderate-A&D,and severe-A&D groups,the SAS and SDS scores with the New York Heart Association(NYHA)functional classification,and cardiac markers and inflammatory factors between the no/mild-A&D and moderate/severe-A&D groups.Regression analysis was performed on the markers with P<0.05 to determine their ability to predict A&D severity in patients and the area under the receiver operating characteristic curve(AUROC)was used to evaluate their accuracy.RESULTS In the inter-group comparison,the following variables had an effect on A&D severity in patients with CHF:NYHA class,left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter,N-terminal pro-brain natriuretic peptide(NT-proBNP),interleukin-6(IL-6),and tumor necrosis factor-alpha(P<0.05).Other variables did not differ significantly between the A&D groups(P>0.05).In addition,we found that higher NYHA classes were associated with higher the SAS and SDS scores(P<0.05).Regression analysis showed that LVEF,NTproBNP,and IL-6 were independent risk factors for A&D severity(P<0.05).Among them,NT-proBNP had the best predictive ability as a single indicator(AUROC=0.781).Furthermore,the combination of these three indicators exhibited a good predictive effect toward discriminating the extent of A&D severity among patients(AUROC=0.875).CONCLUSION Cardiac and inflammatory biomarkers,such as LVEF,NT-proBNP,and IL-6,are correlated with A&D severity in patients with CHF and have predictive value.

Effect of dapagliflozin on uric acid in patients with chronic heart failure and hyperuricemia

BACKGROUND Patients with chronic heart failure(CHF)frequently develop hyperuricemia,an elevated serum uric acid level,associated with adverse outcomes.Dapagliflozin,a sodium-glucose cotransporter-2 inhibitor,demonstrates reduction in cardiovascular mortality and hospitalization in patients with CHF and ejection fraction(HFrEF),irrespective of diabetes.However,dapagliflozin’s effect on the uric acid levels in patients with CHF and hyperuricemia remain unclear.AIM To investigate the effects of dapagliflozin on uric acid levels in CHF patients with hyperuricemia.METHODS We conducted a randomized,double-blind,placebo-controlled trial in 200 patients with CHF and hyperuricemia,with HFrEF and serum uric acid levels≥7 mg/dL(≥416μmol/L).The participants were randomly assigned to receive a daily dose of 10 mg dapagliflozin or placebo for 24 months.The primary endpoint was the change in serum uric acid level from baseline to 24 months.Secondary endpoints included changes in left ventricular ejection fraction(LVEF),Nterminal pro-B-type natriuretic peptide(NT-proBNP),and quality of life(QoL)scores,as well as the incidence of cardiovascular death and hospitalization for heart failure.RESULTS At 24 months,dapagliflozin significantly reduced serum uric acid levels by 1.2 mg/dL(71μmol/L)compared with placebo(95%CI:-1.5 to-0.9;P<0.001).Dapagliflozin also significantly improved LVEF by 3.5%(95%CI:2.1-4.9;P<0.001),NT-proBNP by 25%(95%CI:18-32;P<0.001),and QoL scores by 10 points(95%CI:7-13;P<0.001)and reduced the risk of cardiovascular death and hospitalization for heart failure by 35%(95%CI:15–50;P=0.002)compared with the placebo.Adverse events were similar between the two groups,except for a higher rate of genital infections in the dapagliflozin group(10%vs 2%,P=0.01).CONCLUSION Dapagliflozin significantly lowered serum uric acid levels and improved the clinical outcomes in patients with CHF and hyperuricemia.Therefore,dapagliflozin may be a useful therapeutic option for this high-risk population.

Clinical intervention effect of Xuefu Zhuyu decoction on chronic heart failure complicated with depression

BACKGROUND The diagnosis and treatment of depression in patients with chronic heart failure(CHF)is challenging,with no ideal treatment at present.AIM To analyze the clinical intervention effect of Xuefu Zhuyu decoction(XFZYD)on CHF complicated with depression.METHODS The study cohort comprised 116 patients with CHF complicated with depression who received treatment from July 2020 to July 2023,of which 55 received Western medicine(control group)and 61 received XFZYD(research group).Data on clinical effectiveness,traditional Chinese medicine(TCM)syndrome score,cardiac function,negative emotions,and serum inflammatory factors,were collected for comparative analyses.RESULTS Compared with the control group,the research group had an evidently higher total effective rate.Furthermore,there were marked reductions in TCM symptom score,left ventricular end-diastolic diameter,left ventricular end-systolic diameter,Self-Rating Depression Scale,Hamilton Depression Scale,high-sensitivity C-reactive protein,monocyte chemoattractant protein-1,and matrix metalloproteinase-9 in the research group after treatment,and these were lower than the corresponding values in the control group.Left ventricular ejection fraction was increased and higher in the research group compared with the control group after treatment.CONCLUSION Our findings conclusively proved that XFZYD was considerably superior to Western medicine for treating CHF complicated with depression because it significantly alleviated patients’symptoms,improved cardiac function,relieved negative emotions,and reduced the levels of serum inflammatory factors.

Cardiac evaluation of renal transplant candidates with heart failure

Patients with advanced kidney disease are at elevated risk of developing heart failure and appropriate risk stratification is important to permit them to receive kidney transplantation.The American Heart Association and American College of Cardiology joint statement provides guidance on risk stratification for the major cause of heart failure for these patients in its recommendations for coronary heart disease.Herein we provide an overview of the available literature on risk strati-fication for nonischemic heart failure and functional heart disease states such as pulmonary hypertension.Many of these options for optimizing these patients be-fore transplant include optimizing their volume status,often with more agg-ressive ultrafiltration.Kidney transplantation remains the treatment of choice for patients with advanced kidney disease and cardiac disease,the correction of the azotemic substances with kidney transplantation has been associated with imp-roved survival than remaining on dialysis long-term.The findings in the studies reviewed here are expected to help clinicians refine current strategies for evalua-ting potential kidney transplant recipients.

Network pharmacology-based exploration of molecular mechanisms underlying therapeutic effects of Jianpi Huatan Quyu recipe on chronic heart failure with spleen Qi deficiency syndrome

BACKGROUND Chronic heart failure is a complex clinical syndrome.The Chinese herbal compound preparation Jianpi Huatan Quyu recipe has been used to treat chronic heart failure;however,the underlying molecular mechanism is still not clear.AIM To identify the effective active ingredients of Jianpi Huatan Quyu recipe and explore its molecular mechanism in the treatment of chronic heart failure.METHODS The effective active ingredients of eight herbs composing Jianpi Huatan Quyu recipe were identified using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform.The target genes of chronic heart failure were searched in the Genecards database.The target proteins of active ingredients were mapped to chronic heart failure target genes to obtain the common drugdisease targets,which were then used to construct a key chemical componenttarget network using Cytoscape 3.7.2 software.The protein-protein interaction network was constructed using the String database.Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed through the Metascape database.Finally,our previously published relevant articles were searched to verify the results obtained via network pharmacology.RESULTS A total of 227 effective active ingredients for Jianpi Huatan Quyu recipe were identified,of which quercetin,kaempferol,7-methoxy-2-methyl isoflavone,formononetin,and isorhamnetin may be key active ingredients and involved in the therapeutic effects of TCM by acting on STAT3,MAPK3,AKT1,JUN,MAPK1,TP53,TNF,HSP90AA1,p65,MAPK8,MAPK14,IL6,EGFR,EDN1,FOS,and other proteins.The pathways identified by KEGG enrichment analysis include pathways in cancer,IL-17 signaling pathway,PI3K-Akt signaling pathway,HIF-1 signaling pathway,calcium signaling pathway,cAMP signaling pathway,NF-kappaB signaling pathway,AMPK signaling pathway,etc.Previous studies on Jianpi Huatan Quyu recipe suggested that this Chinese compound preparation can regulate the TNF-α,IL-6,MAPK,cAMP,and AMPK pathways to affect the mitochondrial structure of myocardial cells,oxidative stress,and energy metabolism,thus achieving the therapeutic effects on chronic heart failure.CONCLUSION The Chinese medicine compound preparation Jianpi Huatan Quyu recipe exerts therapeutic effects on chronic heart failure possibly by influencing the mitochondrial structure of cardiomyocytes,oxidative stress,energy metabolism,and other processes.Future studies are warranted to investigate the role of the IL-17 signaling pathway,PI3K-Akt signaling pathway,HIF-1 signaling pathway,and other pathways in mediating the therapeutic effects of Jianpi Huatan Quyu recipe on chronic heart failure.

Investigation on the mechanism of Qiangxinhuoli prescription in the treatment of chronic heart failure based on p38-MAPK signaling pathway

Background:The aim of this study is to investigate the mechanism of action underlying the therapeutic effects of the national patent Chinese medicine compound“Qiangxinhuoli prescription(QXHLF)”on chronic heart failure(CHF).Methods:In vitro,the H_(9)C_(2) cell model was induced by ANGII,and cell proliferation and related protein expression were detected by Cell Counting Kit-8 and Western blot.In vivo,A rat model of CHF was prepared by ligation of the left anterior descending coronary artery.The effects of QXHLF on cardiac function in CHF rats were evaluated by cardiac index,hemodynamic changes,enzyme-linked immunosorbent assay,hematoxylin-eosin staining,immunohistochemistry,Western blot and RT-PCR.The expression of pro-apoptotic factors and anti-apoptotic factors,as well as TGFβ1,p-p38,TAK 1 mRNA,and protein,were detected.Results:In vitro,QXHLF has a significant inhibitory effect on the proliferation of H_(9)C_(2) cells.QXHLF can reduce the expression levels of TAK 1,TGFβ1,p-p38,Caspase3 and BAX proteins in H_(9)C_(2) cells,and increase the expression level of BCL_(2) protein.In vivo,QXHLF has the potential to increase left ventricular systolic pressure,m aximum rate of change in left ventricular pressure while decreasing left ventricular end diastolic pressure,and inhibiting the serum levels of brain natriuretic peptide.Moreover,QXHLF exhibits significant improvements in the pathological alterations of myocardial cells and fibers in CHF rats,leading to enhanced myocardial tissue morphology and notable advantages in combating myocardial fibrosis.QXHLF can reduce the levels of BAX and Caspase3 and up-regulate the expression of BCL_(2),thereby inhibiting cardiomyocyte apoptosis.Furthermore,QXHLF demonstrates inhibitory effects on the mRNA and protein expression levels of TGFβ_(1),TAK_(1),and p-p38 in the heart tissue of the CHF rat model.Conclusion:These findings indicate that QXHLF has a therapeutic effect on CHF by inhibiting the p38-MAPK signaling pathway,reducing myocardial fibrosis,preventing apoptosis,inhibiting cell proliferation,and restoring myocardial injury.

Serum cystatin C,monocyte/high-density lipoprotein-C ratio,and uric acid for the diagnosis of coronary heart disease and heart failure

BACKGROUND Coronary heart disease(CHD)and heart failure(HF)are the major causes of morbidity and mortality worldwide.Early and accurate diagnoses of CHD and HF are essential for optimal management and prognosis.However,conventional diagnostic methods such as electrocardiography,echocardiography,and cardiac biomarkers have certain limitations,such as low sensitivity,specificity,availability,and cost-effectiveness.Therefore,there is a need for simple,noninvasive,and reliable biomarkers to diagnose CHD and HF.AIM To investigate serum cystatin C(Cys-C),monocyte/high-density lipoprotein cholesterol ratio(MHR),and uric acid(UA)diagnostic values for CHD and HF.METHODS We enrolled 80 patients with suspected CHD or HF who were admitted to our hospital between July 2022 and July 2023.The patients were divided into CHD(n=20),HF(n=20),CHD+HF(n=20),and control groups(n=20).The serum levels of Cys-C,MHR,and UA were measured using immunonephelometry and an enzymatic method,respectively,and the diagnostic values for CHD and HF were evaluated using receiver operating characteristic(ROC)curve analysis.RESULTS Serum levels of Cys-C,MHR,and UA were significantly higher in the CHD,HF,and CHD+HF groups than those in the control group.The serum levels of Cys-C,MHR,and UA were significantly higher in the CHD+HF group than those in the CHD or HF group.The ROC curve analysis showed that serum Cys-C,MHR,and UA had good diagnostic performance for CHD and HF,with areas under the curve ranging from 0.78 to 0.93.The optimal cutoff values of serum Cys-C,MHR,and UA for diagnosing CHD,HF,and CHD+HF were 1.2 mg/L,0.9×10^(9),and 389μmol/L;1.4 mg/L,1.0×10^(9),and 449μmol/L;and 1.6 mg/L,1.1×10^(9),and 508μmol/L,respectively.CONCLUSION Serum Cys-C,MHR,and UA are useful biomarkers for diagnosing CHD and HF,and CHD+HF.These can provide information for decision-making and risk stratification in patients with CHD and HF.
