Cardiorenal syndrome is the condition in which these two organs negatively affect each other, therefore an accurate evaluation of renal function in the clinical setting of CHF is essential. This review aims to revise the parameters currently used to evaluate renal dysfunction in CHF with particular reference to the usefulness and the limitations of biomarkers in evaluating glomerular dysfunction and tubular damage. Moreover, it is reported the possible utility of renal arterial resistance index(a parameter associated with abnormalities in renal vascular bed) for a better assesment of kidney disfunction.展开更多

AF is a commonly encountered comorbidity in patients with cardiac and major non-cardiac diseases. Morbidity and mortality associated with AF makes it a major healthcare burden. The objective of our article is to determine the prognostic impact of AF on acute coronary syndromes,heart failure and chronic kidney disease. Multiple studies have been conducted to determine if AF has an independent role in the overall mortality of such patients. Our review suggests that AF has an independent adverse prognostic impact on the clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease.展开更多

Patients and methods: Between January 2003 and December 2009, seven subjects underwent combined HKT, receiving both organs from a single donor. Their age ranged from 30 years to 59 years, six were male. Five patients were dialysis dependent before transplantation and two were in chronic renal failure (serum creatinine levels > 2.6 mg/dL). The heart was transplanted first in all cases. Results: Heart function rapidly re-covered in five of the patients, while two needed temporary inotropic and mechanical support. Diuresis started immediately in four patients. At discharge, all patients had well-functioning grafts (left ventricular ejection fraction 60% ± 6%;serum creatinine 1.4 ± 0.3 mg/dL). After an average follow-up period of 45 ± 24 months no deaths have occurred. Heart allografts are functioning normally in six patients and none of the patients currently require dialysis treatment. The main adverse event noted during follow-up was hypertension in five patients. Four patients were cardiac allograft rejection free and five patients were kidney rejection free. Conclusion: Our results are in line with the data which has been previously reported in the literature and suggest that HKT is a viable therapeutic choice in the treatment of advanced cardiac and renal failure in carefully selected patients.展开更多

It was aimed to have a comparison of this protection to heart, liver and kidney in the treated subjects. In this study, groups of mice were treated with Dox and melatonin and their individual or combined effects were evaluated by assessing lipidperoxidation, non-protein sulfhydryls (NP-SH) and nitrate/nitrite (NO) contents in these tissues. Plasma aminotransferases, LDH and CK-MB enzyme activities were measured. Moreover, these tissues were subject to histopathological assessment. MEL co-treatment significantly prevented any rise in lipidperoxides more significantly in heart and liver as compared to kidney. In tandem, MEL prevented a decline in GSH that was observed by Dox alone in liver and kidney. Dox significantly increased total NO levels in all the tissues. Melatonin at both dose levels could not afford protection against nitrosative stress. MEL in combination treatment provided significant展开更多

The objective of this study was to examine the clinical and laboratory characteristics of a large cohort of patients with HFpEF and markedly elevated BNP. A retrospective examination of 421 inpatients at a university hospital admitted with a diagnosis of HFpEF was performed. Clinical and echocardiographic data in 4 groups of patients with levels of BNP ≤ 100 pg/mL, 100-400 pg/mL, 400-1,000 pg/mL and 〉 1,000 pg/mL were compared. Patients with HFpEF and BNP 〉 1,000 pg/mL (28% of the population) were characterized by impaired renal function and greater use of anti-hypertensive medications. A subset of these patients with BNP 〉 1,000 pg/mL had normal renal function (21%) and were significantly older, more frequently female, and tended to have lower ejection fractions. Conversely, patients with HFpEF and BNP ≤100 pg/mL were younger and had preserved renal function. BNP was inversely related to the likelihood of subsequent admission for heart failure, but not to myocardial infarction or death. In conclusion: BNP 〉 1,000 pg/mL is seen in almost 1/3 of patients hospitalized with HFpEF. This elevation of BNP often reflects impaired renal function, but can also be seen in patients with preserved renal function but relatively impaired systolic function.展开更多

Although both heart and kidneys are separated by a quite distance within the body and they perform varied functions, there is a close physiological relationship between them. The diseases in the kidneys can trigger a disease in the heart and vice versa. High blood pressure is the most significant risk factor for the development and progression of chronic kidney disease (CKD). Lowering blood pressure is a goal to prevent CKD progress. Chronic abnormalities in cardiac function (e.g., chronic congestive heart failure) causing, chronic kidney disease and anemia appear to act together in a vicious circle in which each condition causes or exacerbates the other progressive chronic kidney disease. <strong>Objective:</strong> To assess the prevalence of chronic kidney disease in patients with cardiovascular disease at Shebin El-Kom Teaching Hospital and Menoufia University Hospital Cardiology Outpatient Clinic, Menoufia Governorate, Egypt. <strong>Methods:</strong> This is a cross-sectional study that was conducted in Shebin El-Kom Teaching Hospital Cardiology Outpatient Clinic, Menoufia University Cardiology Outpatient Clinic from April 2019 to July 2019. This study included 200 patients with cardiovascular disease or hypertension for more than 6 months. All patients were subjected to detailed history taking, clinical examination, laboratory investigation, echo and abdominal ultrasound. <strong>Results:</strong> This study included 200 patients with cardiovascular disease or hypertension for more than 6 months, which showed that: 63 (31.5%) were diagnosed as chronic kidney disease, 24 (38%) known to be CKD, 39 (62%) not known diagnosed in our study. Uncontrolled hypertension, congestive heart failure, diuretics and ACEI or ARBS with diuretics together are significant risk factors for renal impairment;uncontrolled hypertension and diuretics are the most predictors for renal impairment. <strong>Conclusion:</strong> Uncontrolled hypertension is the most preventable cause of renal impairment;RAAS not cause renal impairment but lead to decreased GFR in CKD patients. We should be careful with ACEI or ARBS with diuretics or diuretics only and control congestive heart disease to avoid kidney injury and chronic cardiorenal.展开更多

It remains the leading indication for liver transplant worldwide and has been demonstrated to negatively impact both patient and graft survival following non-hepatic organ transplantation. In the era of interferon-based therapy, although treatment and cure of HCV prior to nonhepatic transplant improved survival, tolerability and low cure rates substantially limited therapy. Interferon(IFN)-based therapy following non-hepatic solid organ transplant, due to the risk of allograft rejection, is generally contraindicated. Rapid advances in IFN-free therapy with direct acting antivirals(DAAs) in the last few years have completely changed the paradigm of hepatitis C therapy. Compared to IFN-based regimens, DAAs have less frequent and less severe adverse effects, shorter durations of therapy, and higher cure rates that are minimally impacted by historically negative predictors of response such as cirrhosis, ethnicity, and post-transplant state. Recent studies have shown that liver transplant(LT) recipients can be safely and effectively treated with DAA combination therapies; although data are limited, many of the principles of therapy in LT may be extrapolated to non-hepatic solid organ transplant recipients. Here we review the data on DAA combination therapies in transplantation, discuss the advantages and disadvantages of pre- vs post-transplant HCV therapy and future directions.展开更多

Types 1 and 2 involve acute and chronic cardiovascular disease (CVD) scenarios leading to acute kidney injury or accelerated chronic kidney disease. Types 2 and 3 describe acute and chronic kidney disease leading primarily to heart failure, although it is possible that acute coronary syndromes, stroke, and arrhythmias could be CVD outcomes in these forms of CRS.

Both blood and urine biomarkers are reviewed in this paper and offer a considerable opportunity to enhance the understanding of the pathophysiology and known epidemiology of these recently defined syndromes.展开更多
文摘Objective Variations are present in common clinical practices regarding best practice in managing hyperkalaemia(HK),there is therefore a need to establish a multi-specialty approach to optimal renin angiotension-aldosterone system inhibitors(RAASi)usage and HK management in patients with chronic kidney disease(CKD)&heart failure(HF).This study aimed to establish a multi-speciality approach to the optimal use of RAASi and the management of HK in patients with CKD and HF.Methods A steering expert group of cardiology and nephrology experts across China were convened to discuss challenges to HK management through a nominal group technique.The group then created a list of 41 statements for a consensus questionnaire,which was distributed for a further survey in extended panel group of cardiologists and nephrologists across China.Consensus was assessed using a modified Delphi technique,with agreement defined as"strong"(≥75%and<90%)and"very strong"(≥90%).The steering group,data collection,and analysis were aided by an independent facilitator.Results A total of 150 responses from 21 provinces across China were recruited in the survey.Respondents were comprised of an even split(n=75,50%)between cardiologists and nephrologists.All 41 statements achieved the 75%consensus agreement threshold,of which 27 statements attained very strong consensus(≥90%agreement)and 14 attained strong consensus(agreement between 75%and 90%).Conclusion Based on the agreement levels from respondents,the steering group agreed a set of recommendations intended to improve patient outcomes in the use of RAASi therapy and HK management in China.
文摘BACKGROUND The association between congenital heart disease and chronic kidney disease is well known.Various mechanisms of kidney damage associated with congenital heart disease have been established.The etiology of kidneydisease has commonly been considered to be secondary to focal segmental glomerulosclerosis(FSGS),however,this has only been demonstrated in case reports and not in observational or clinical trials.AIM To identify baseline and clinical characteristics,as well as the findings in kidney biopsies of patients with congenital heart disease in our hospital.METHODS This is a retrospective observational study conducted at the Nephrology Depart-ment of the National Institute of Cardiology“Ignacio Chávez”.All patients over 16 years old who underwent percutaneous kidney biopsy from January 2000 to January 2023 with congenital heart disease were included in the study.RESULTS Ten patients with congenital heart disease and kidney biopsy were found.The average age was 29.00 years±15.87 years with pre-biopsy proteinuria of 6193 mg/24 h±6165 mg/24 h.The most common congenital heart disease was Fallot’s tetralogy with 2 cases(20%)and ventricular septal defect with 2(20%)cases.Among the 10 cases,one case of IgA nephropathy and one case of membranoproliferative glomerulonephritis associated with immune complexes were found,receiving specific treatment after histopathological diagnosis,delaying the initiation of kidney replacement therapy.Among remaining 8 cases(80%),one case of FSGS with perihilar variety was found,while the other 7 cases were non-specific FSGS.CONCLUSION Determining the cause of chronic kidney disease can help in delaying the need for kidney replacement therapy.In 2 out of 10 patients in our study,interventions were performed,and initiation of kidney replacement therapy was delayed.Prospective studies are needed to determine the usefulness of kidney biopsy in patients with congenital heart disease.
文摘Objective:To investigate the clinical nursing intervention effect of moxibustion on abdominal distension symptoms in heart failure(heart and kidney yang deficiency and blood stasis blocking collaterals syndrome).Methods:62 patients with heart failure(heart and kidney yang deficiency and blood stasis blocking collaterals syndrome)admitted to our hospital from February 2023 to February 2024 were selected and divided into the observation group(n=31)and the control group(n=31)by using the random numerical table method.The control group adopted conventional nursing interventions,and the observation group received the nursing program of the control group with the addition of moxibustion nursing interventions.The nursing effectiveness,quality of life scores,and nursing satisfaction were compared between the two groups.Results:The nursing effectiveness of the observation group was significantly higher than the control group(P<0.05);the quality of life score of the observation group was significantly higher than the control group(P<0.05);the nursing satisfaction of the observation group was significantly higher than that of the control group(P<0.05).Conclusion:The use of moxibustion nursing intervention in patients with heart failure(heart and kidney yang deficiency and blood stasis blocking collaterals syndrome)can effectively relieve the symptoms of abdominal distension,improve patients'quality of life,and increase nursing satisfaction,which has promotion and application values.

文摘Purpose:This study sought to explore the effect of intraoperative mean blood glucose levels and variability on postoperative acute kidney injury(AKI)in children undergoing congenital cardiac surgery.Methods:We conducted a prospective nested case-control study in children(age<18 years)undergoing congenital heart surgery with cardiopulmonary bypass(CPB)at the Fuwai Hospital between April 01,2022 and July 30,2022.Cases were individuals who developed AKI within the first postoperative 7 days(AKI group)and controls were those without AKI(Non-AKI group)according to KDIGO criteria.AKI and Non-AKI groups unmatched and 1:1 matched by age,sex,and baseline serum creatinine were separately analyzed.Multivariate logistic and conditional logistic regressions were used to assess the associations between blood glucose variables and AKI.Results:688 consecutively approached patients were included in the final analysis.On multivariate analysis,intra-CPB(adjusted odds ratio[OR]0.802;95%confidence interval[CI],0.706 to 0.912;p=0.001)and post-CPB(adjusted OR 0.830;95%CI,0.744 to 0.925;p=0.001)blood glucose levels were associated with postoperative AKI.There were no significant differences in pre-CPB blood glucose(adjusted OR 0.926;95%CI,0.759 to 1.129;p=0.446)or intraoperative glycemic fluctuations(adjusted OR 0.905;95%CI,0.723 to 1.132;p=0.382)between AKI and Non-AKI groups.Results based on matched cases and controls were consistent with those from the unmatched analyses.Conclusion:Higher intraoperative blood glucose levels during and after CPB were protective factors against postoperative AKI in pediatric patients after congenital heart surgery.
文摘Sodium glucose cotransporter-2 inhibitors(SGLT-2i)are antidiabetic medications with remarkable cardiovascular(CV)benefits proven by multiple randomised controlled trials and real-world data.These drugs are also useful in the prevention of CV disease(CVD)in patients with diabetes mellitus(DM).Although DM as such is a huge risk factor for CVD,the CV benefits of SGLT-2i are not just because of antidiabetic effects.These molecules have proven beneficial roles in prevention and management of nondiabetic CVD and renal disease as well.There are various molecular mechanisms for the organ protective effects of SGLT-2i which are still being elucidated.Proper understanding of the role of SGLT-2i in prevention and management of CVD is important not only for the cardiologists but also for other specialists caring for various illnesses which can directly or indirectly impact care of heart diseases.This clinical review compiles the current evidence on the rational use of SGLT-2i in clinical practice.

文摘Background Heart failure(HF)is a leading cause of hospitalization and mortality for older chronic kidney disease(CKD)patients.However,the epidemiological data is scarce.We aimed to determine the prevalence of left ventricular(LV)dysfunction and HF,and to explore the risk factors for HF among those patients.Methods This is a cross-sectional analysis of the China Hypertension Survey conducted between October 2012 and December 2015.A total of 5,808 participants aged≥65 years were included in the analysis.Self-reported history of HF and any other cardiovascular diseases was acquired.2-D and Doppler echocardiography were used to assess LV dysfunction.CKD was defined as either estimated glomerular filtration rate(eGFR)<60 mL/min per 1.73 m2 or urinary albumin to creatinine ratio(ACR)≥30 mg/g.Results Among CKD patients aged≥65 years,the weighted prevalence of HF,heart failure with preserved ejection fraction(HFpEF),heart failure with mid-range ejection fraction(HFmrEF),and heart failure with reduced ejection fraction(HFrEF)was 4.8%,2.5%,0.8%,and 1.7%,respectively.The weighted prevalence of HF was 5.0%in patients with eGFR<60 mL/min per 1.73 m2,and was 5.9%in patients with ACR≥30 mg/g.The prevalence of LV systolic dysfunction was 3.1%,and while it was 8.9%for moderate/severe diastolic dysfunction.Multivariate analysis showed that smoking was significantly associated with the risk of HF.Furthermore,age,smoking,and residents in rural areas were significantly associated with a risk of LV diastolic dysfunction.Conclusions The prevalence of HF and LV dysfunction was high in older patients with CKD,suggesting that particular strategies will be required.
文摘Chronic kidney disease and its worsening are recurring conditions in chronic heart failure(CHF) which are independently associated with poor patient outcome.The heart and kidney share many pathophysiological mechanisms which can determine dysfunction in each organ. Cardiorenal syndrome is the condition in which these two organs negatively affect each other, therefore an accurate evaluation of renal function in the clinical setting of CHF is essential. This review aims to revise the parameters currently used to evaluate renal dysfunction in CHF with particular reference to the usefulness and the limitations of biomarkers in evaluating glomerular dysfunction and tubular damage. Moreover, it is reported the possible utility of renal arterial resistance index(a parameter associated with abnormalities in renal vascular bed) for a better assesment of kidney disfunction.
文摘Atrial fibrillation(AF) is the most common type of sustained arrhythmia,which is now on course to reach epidemic proportions in the elderly population. AF is a commonly encountered comorbidity in patients with cardiac and major non-cardiac diseases. Morbidity and mortality associated with AF makes it a major healthcare burden. The objective of our article is to determine the prognostic impact of AF on acute coronary syndromes,heart failure and chronic kidney disease. Multiple studies have been conducted to determine if AF has an independent role in the overall mortality of such patients. Our review suggests that AF has an independent adverse prognostic impact on the clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease.
文摘BACKGROUND The SEMA3A gene,which is located at 7q21.11,is involved in hypothalamic neuron migration,heart development,kidney development,and skeleton metabolism.Mutation of the SEMA3A gene is associated with Kallmann syndrome 16 with or without a normal sense of smell.In addition,two case reports showed that mutation of the SEMA3A gene could cause short stature,low gonadotropin,hypogonadism,thoracic deformity,a high scapula,rib and lower limb deformity,facial deformity(long face,epicanthic folds,backwards ears),and arterial malformation.CASE SUMMARY We reported the case of a 26-year-old Chinese man who was admitted because of short stature.Physical examination showed that he had many abnormal symptoms,including a short neck,facial moles,knee valgus,transverse palm,continuous grade 5/6 murmurs in the pulmonary auscultation area,no whiskers,or pubic hair,no Adam’s apple,short penis and cryptorchidism.Radiological examination showed pituitary,gonad,heart,kidney and skeletal dysplasia.The laboratory tests revealed low growth hormone,luteinizing hormone,folliclestimulating hormone,testosterone and estrogen.Clinical whole-exome detection showed that our patient,unlike previously reported patients,has a new SEMA3A gene mutation(c.950A>G).Now,his height has increased by 3 cm.In addition,he has a good appetite and reduced subcutaneous fat over 3 mo of recombinant human growth hormone injections therapy.Unfortunately,he refuses further treatment about gonad.CONCLUSION Patients who come to a hospital because of their short stature must undergo gene detection if they have other simultaneous abnormal phenotypes.
文摘Renal dysfunction is common in patients with heart failure(HF) and can complicate HF therapy.Treating patients with HF and kidney disease is difficult and requires careful assessment,monitoring and balancing of risk between potential benefits of treatment and adverse impact on renal function.In this review,we address the pathophysiological contexts and management options in this adversarial relation between the heart and the kidney,which exists in a substantial proportion of HF patients.Angiotensin converting enzyme inhibitors and β-blockers are associated with similar reductions in mortality in patients with and without renal insufficiency but usually are less often prescribed in patients with renal insufficiency.Careful monitoring of side effects and renal function should be done in all patients with renal insufficiency and prompt measures should be adopted to prevent further complications.
文摘Introduction: We report our experience with seven cases of combined heart-kidney transplantation (HKT). Patients and methods: Between January 2003 and December 2009, seven subjects underwent combined HKT, receiving both organs from a single donor. Their age ranged from 30 years to 59 years, six were male. Five patients were dialysis dependent before transplantation and two were in chronic renal failure (serum creatinine levels > 2.6 mg/dL). The heart was transplanted first in all cases. Results: Heart function rapidly re-covered in five of the patients, while two needed temporary inotropic and mechanical support. Diuresis started immediately in four patients. At discharge, all patients had well-functioning grafts (left ventricular ejection fraction 60% ± 6%;serum creatinine 1.4 ± 0.3 mg/dL). After an average follow-up period of 45 ± 24 months no deaths have occurred. Heart allografts are functioning normally in six patients and none of the patients currently require dialysis treatment. The main adverse event noted during follow-up was hypertension in five patients. Four patients were cardiac allograft rejection free and five patients were kidney rejection free. Conclusion: Our results are in line with the data which has been previously reported in the literature and suggest that HKT is a viable therapeutic choice in the treatment of advanced cardiac and renal failure in carefully selected patients.
文摘Melatonin (MEL) was investigated for protection against the anthracycline antibiotic doxorubicin (Dox) that is well known for its oxidative damage to various body organs. It was aimed to have a comparison of this protection to heart, liver and kidney in the treated subjects. In this study, groups of mice were treated with Dox and melatonin and their individual or combined effects were evaluated by assessing lipidperoxidation, non-protein sulfhydryls (NP-SH) and nitrate/nitrite (NO) contents in these tissues. Plasma aminotransferases, LDH and CK-MB enzyme activities were measured. Moreover, these tissues were subject to histopathological assessment. MEL co-treatment significantly prevented any rise in lipidperoxides more significantly in heart and liver as compared to kidney. In tandem, MEL prevented a decline in GSH that was observed by Dox alone in liver and kidney. Dox significantly increased total NO levels in all the tissues. Melatonin at both dose levels could not afford protection against nitrosative stress. MEL in combination treatment provided significant
文摘'Harmony between the heart and kidney' refers to the physiological relationship between these two zang organs in Chinese medicine,while 'disharmony between the heart and kidney' (also called disharmony between fire and water) refers to the pathological state.The pattern of disharmony between the heart and kidney is widely observed in patients with insomnia,anxiety disorder and menopausal syndrome,etc..In order to gain a full and systematical understanding of this pattern,from the perspective of ancient Chinese philosophy and zang-fu theory in Chinese medicine,we systematically reviewed and discussed the functions and physiological characteristics of the heart and kidney,the origin and development of theories relating to heart-kidney relationship,the pathogenesis and identification of the pattern,as well as the commonly used classical formulas for its treatment,including Coptis and DonkeyHide Gelatin Decoction (Huánglián (E)jiāo Tāng) and Grand Communication Pill (Jiāotài Wán).Two examples of clinical modifications of these formulas in the treatment of insomnia and menopausal syndrome are provided in this article.It should be noted that in clinical practice,these formulas should be used flexibly,and modified in accordance to the condition of the patient.

文摘Objective:The risk of acute kidney injury(AKI)is high in patients with acute decompensated heart failure(ADHF).The aim of this study is to analyze the role of urinary neutrophil gelatinase-associated lipocalin(uNGAL)in diagnosing AKI in patients with ADHF and evaluate the therapeutic effect of angiotensin receptor-neprilysin inhibitor(ARNI)on AKI.Method:Sixty patients with ADHF were enrolled at the First Affiliated Hospital of Kangda College of Nanjing Medical University from January 2020 to June 2021,and randomized into 2 groups(ARNI group:30 patients treated with tablets of sacubitril valsartan sodium;and angiotensin-converting enzyme inhibitor(ACEI)group:30 patients treated with benazepril).The uNGAL level was measured immediately after as well as 1,2,3,and 7 d after hospital admission.The serum creatinine(sCr)level and estimated glomerular filtration rate(eGFR)were measured immediately as well as 2 and 7 d after hospital admission.The urine volume,dose of loop diuretics,and duration of hospital stay(DoHS)were recorded.Result:The most valuable diagnostic metric for AKI in patients with ADHF was the uNGAL level 1 d after hospital admission,which had a sensitivity of 0.94,specificity of 0.84,and optimal cutoff of 125.62μg/L.In the presence of AKI,during the first 2 d,patients in the ARNI-AKI and ACEI-AKI groups showed an increase in the sCr level and a reduction in the eGFR level,but there was no significant difference between the 2 groups(P>0.05).After 7 d of treatment,the sCr level decreased and the eGFR level increased in both groups,with a significantly greater changes being observed in the ARNI-AKI group than in the ACEI-AKI group(P<0.05,respectively).In the absence of AKI,the difference in the sCr level and eGFR between the 2 groups was not significant.The DoHS((11.25±2.38)d vs.(14.11±2.89)d),urinary microalbumin level((22.95±6.04)mg/L vs.(31.91±2.18)mg/L),and daily dose of loop diuretics((19.03±3.04)mg/d vs.(23.62±4.46)mg/d)were significantly lower in patients with AKI in the ARNI group than in the ACEI group(P<0.05,respectively).Conclusion:In patients with ADHF,uNGAL measurement enables the diagnosis of AKI earlier than that using the sCr level by 1 to 2 d.ARNI treatment reduced the sCr level,facilitated eGFR recovery,reduced the daily dose of loop diuretics,and decreased the DoHS compared with that in patients receive ACEI treatment.

文摘Marked elevations of B-type natriuretic peptide (BNP) are not generally seen in patients with heart failure and preserved ejection fraction (HFpEF). The objective of this study was to examine the clinical and laboratory characteristics of a large cohort of patients with HFpEF and markedly elevated BNP. A retrospective examination of 421 inpatients at a university hospital admitted with a diagnosis of HFpEF was performed. Clinical and echocardiographic data in 4 groups of patients with levels of BNP ≤ 100 pg/mL, 100-400 pg/mL, 400-1,000 pg/mL and 〉 1,000 pg/mL were compared. Patients with HFpEF and BNP 〉 1,000 pg/mL (28% of the population) were characterized by impaired renal function and greater use of anti-hypertensive medications. A subset of these patients with BNP 〉 1,000 pg/mL had normal renal function (21%) and were significantly older, more frequently female, and tended to have lower ejection fractions. Conversely, patients with HFpEF and BNP ≤100 pg/mL were younger and had preserved renal function. BNP was inversely related to the likelihood of subsequent admission for heart failure, but not to myocardial infarction or death. In conclusion: BNP 〉 1,000 pg/mL is seen in almost 1/3 of patients hospitalized with HFpEF. This elevation of BNP often reflects impaired renal function, but can also be seen in patients with preserved renal function but relatively impaired systolic function.

文摘AIM:To study if impaired renal function is associated with increased risk of peri-infarct heart failure (HF) in patients with preserved ejection fraction (EF).METHODS:Patients with occluded infarct-related arteries (IRAs) between 1 to 28 d after myocardial infarction (MI) were grouped into chronic kidney disease (CKD) stages based on estimated glomerular filtration rate (eGFR).Rates of early post-MI HF were compared among eGFR groups.Logistic regression was used to explore independent predictors of HF.RESULTS:Reduced eGFR was present in 71.1% of 2160 patients,with significant renal impairment (eGFR < 60 mL/min every 1.73 m2) in 14.8%.The prevalence of HF was higher with worsening renal function:15.5%,17.8% and 29.4% in patients with CKD stages 1,2 and 3 or 4,respectively (P < 0.0001),despite a small absolute difference in mean EF across eGFR groups:48.2 ± 10.0,47.9 ± 11.3 and 46.2 ± 12.1,respectively (P=0.02).The prevalence of HF was again higher with worsening renal function among patients with preserved EF:10.1%,13.6% and 23.6% (P < 0.0001),but this relationship was not significant among patients with depressed EF:27.1%,26.2% and 37.9% (P= 0.071).Moreover,eGFR was an independent correlate of HF in patients with preserved EF (P=0.003) but not in patients with depressed EF (P=0.181).CONCLUSION:A significant proportion of post-MI patients with occluded IRAs have impaired renal function.Impaired renal function was associated with an increased rate of early post-MI HF,the association being strongest in patients with preserved EF.These findings have implications for management of peri-infarct HF.

文摘<strong>Background:</strong> Chronic kidney disease (CKD) is a worldwide public health alarming problem. Although both heart and kidneys are separated by a quite distance within the body and they perform varied functions, there is a close physiological relationship between them. The diseases in the kidneys can trigger a disease in the heart and vice versa. High blood pressure is the most significant risk factor for the development and progression of chronic kidney disease (CKD). Lowering blood pressure is a goal to prevent CKD progress. Chronic abnormalities in cardiac function (e.g., chronic congestive heart failure) causing, chronic kidney disease and anemia appear to act together in a vicious circle in which each condition causes or exacerbates the other progressive chronic kidney disease. <strong>Objective:</strong> To assess the prevalence of chronic kidney disease in patients with cardiovascular disease at Shebin El-Kom Teaching Hospital and Menoufia University Hospital Cardiology Outpatient Clinic, Menoufia Governorate, Egypt. <strong>Methods:</strong> This is a cross-sectional study that was conducted in Shebin El-Kom Teaching Hospital Cardiology Outpatient Clinic, Menoufia University Cardiology Outpatient Clinic from April 2019 to July 2019. This study included 200 patients with cardiovascular disease or hypertension for more than 6 months. All patients were subjected to detailed history taking, clinical examination, laboratory investigation, echo and abdominal ultrasound. <strong>Results:</strong> This study included 200 patients with cardiovascular disease or hypertension for more than 6 months, which showed that: 63 (31.5%) were diagnosed as chronic kidney disease, 24 (38%) known to be CKD, 39 (62%) not known diagnosed in our study. Uncontrolled hypertension, congestive heart failure, diuretics and ACEI or ARBS with diuretics together are significant risk factors for renal impairment;uncontrolled hypertension and diuretics are the most predictors for renal impairment. <strong>Conclusion:</strong> Uncontrolled hypertension is the most preventable cause of renal impairment;RAAS not cause renal impairment but lead to decreased GFR in CKD patients. We should be careful with ACEI or ARBS with diuretics or diuretics only and control congestive heart disease to avoid kidney injury and chronic cardiorenal.
文摘Hepatitis C virus(HCV) infection is estimated to affect 130-150 million people globally which corresponds to2%-3% of the total world population. It remains the leading indication for liver transplant worldwide and has been demonstrated to negatively impact both patient and graft survival following non-hepatic organ transplantation. In the era of interferon-based therapy, although treatment and cure of HCV prior to nonhepatic transplant improved survival, tolerability and low cure rates substantially limited therapy. Interferon(IFN)-based therapy following non-hepatic solid organ transplant, due to the risk of allograft rejection, is generally contraindicated. Rapid advances in IFN-free therapy with direct acting antivirals(DAAs) in the last few years have completely changed the paradigm of hepatitis C therapy. Compared to IFN-based regimens, DAAs have less frequent and less severe adverse effects, shorter durations of therapy, and higher cure rates that are minimally impacted by historically negative predictors of response such as cirrhosis, ethnicity, and post-transplant state. Recent studies have shown that liver transplant(LT) recipients can be safely and effectively treated with DAA combination therapies; although data are limited, many of the principles of therapy in LT may be extrapolated to non-hepatic solid organ transplant recipients. Here we review the data on DAA combination therapies in transplantation, discuss the advantages and disadvantages of pre- vs post-transplant HCV therapy and future directions.
文摘Cardiorenal syndromes (CRS) have been subclassified as five defined entities which represent clinical circumstances in which both the heart and the kidney are involved in a bidirectional injury and dysfunction via a final common pathway of cell-to-cell death and accelerated apoptosis mediated by oxidative stress. Types 1 and 2 involve acute and chronic cardiovascular disease (CVD) scenarios leading to acute kidney injury or accelerated chronic kidney disease. Types 2 and 3 describe acute and chronic kidney disease leading primarily to heart failure, although it is possible that acute coronary syndromes, stroke, and arrhythmias could be CVD outcomes in these forms of CRS. Finally, CRS type 5 describes a simultaneous insult to both heart and kidneys, such as sepsis, where both organs are injured simultaneously. Both blood and urine biomarkers are reviewed in this paper and offer a considerable opportunity to enhance the understanding of the pathophysiology and known epidemiology of these recently defined syndromes.
