RATIONALE & OBJECTIVE: Abnormal cardiac structure and function are common in chronic kidney disease (CKD) and end-stage renal disease (ESRD) and linked with mortality and heart failure. We examined changes in echocardiographic measures during the transition from CKD to ESRD and their associations with post-ESRD mortality. STUDY DESIGN: Prospective study. SETTING & PARTICIPANTS: We studied 417 participants with CKD in the Chronic Renal Insufficiency Cohort (CRIC) who had research echocardiograms during CKD and ESRD...

PURPOSE OF REVIEW: Patients with chronic kidney disease (CKD) are at a high risk for cardiovascular events and mortality, particularly heart failure. Echocardiography is the most commonly used diagnostic imaging modality for heart failure. The purpose of this review is to summarize recent literature that demonstrates how echocardiography may be used to define cardiac structure and function in the CKD population and to identify echocardiographic abnormalities that have utility in predicting clinical outcomes in this population...

BACKGROUND: Chronic kidney disease (CKD) has been proposed to associate with decreased hydrogen sulfide (H2S) level. Nevertheless, the role of H2S in the pathogenesis of CKD has not been fully investigated. Our study aimed to investigate the plasma level of endogenous H2S in patients with different stages of CKD, and to identify the role of H2S in the progression of CKD and its relationship with cardiovascular diseases. METHODS: A total of 157 non-dialysis CKD patients were recruited in our study, with 37 age- and sex-matched healthy individuals as control...

The Na/K-ATPase is an important membrane ion transporter and a signaling receptor that is essential for maintaining normal cell function. The current study examined the role of Na/K-ATPase signaling in regulating miR-29b-3p, an anti-fibrotic microRNA, in a mouse chronic kidney disease (CKD) model (5/6th partial nephrectomy or PNx). The results showed that CKD induced significant reduction of miR-29b-3p expression in the heart tissue by activation of Src and NFκB signaling in these animals. To demonstrate the role of Na/K-ATPase signaling, we also performed the PNx surgery on Na/K-ATPase α1 heterozygous (α1+/-) mice, which expresses ~40% less Na/K-ATPase α1 compared to their wild type littermates (WT) and exhibits deficiency in Na/K-ATPase signaling...

Left ventricular hypertrophy is the most common organ damage in children with chronic kidney disease (CKD). AIM: The aim of the study was to assess the usefulness of B-type natriuretic peptide (BNP) as a marker of heart injury in children with CKD. MATERIALS AND METHODS: We included 66 children (41 boys and 25 girls) aged 0.7 to 18.6 (median 11.6) years with CKD stage 1-5. The concentrations of urea, creatinine, cystatin C and BNP in blood serum were assessed, and the estimated glomerular filtration rate (eGFR) was calculated from the Schwartz and Filler formulas...

BACKGROUND: The concomitant presence of mitral stenosis (MS) in the setting of symptomatic aortic stenosis represent a clinical challenge. Little is known regarding the outcome of mitral stenosis (MS) patients undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). Therefore, we sought to study the outcome of MS patients undergoing aortic valve replacement (AVR). METHOD: Using weighted data from the National Inpatient Sample (NIS) database between 2011 and 2014, we identified patients who were diagnosed with MS...

Cardiovascular disease is a common and serious complication in patients with chronic kidney disease (CKD). One of the fundamental functions of the cardiovascular system is oxygen delivery, therefore cardiovascular disease inherently is linked to insufficient tissue oxygenation. Advances in our knowledge of cellular oxygen sensing by a family of prolyl hydroxylases (PHDs) and their role in regulating hypoxia-inducible factors (HIFs) have led to the discovery of PHD inhibitors as HIF stabilizers. Several small-molecule PHD inhibitors are currently in clinical trials for the treatment of anemia in CKD...

REVIEW
Shoshana H Ballew, Kunihiro Matsushita
Cardiovascular disease is an important complication for patients with chronic kidney disease (CKD), warranting accurate risk prediction, but clinical guidelines are inconsistent regarding whether or how to use information on measures of CKD for predicting risk. Recent large meta-analyses have shown that key CKD measures (estimated glomerular filtration rate and albuminuria) improve cardiovascular risk prediction beyond traditional risk factors, especially when albuminuria is added to prediction models. In addition, several recent studies have shown that the use of filtration markers other than serum creatinine, cystatin C, and β2 -microglobulin can improve cardiovascular risk prediction...

BACKGROUND: The most commonly used parameter of cardiac function in the chronic kidney disease (CKD) patient is ejection fraction (EF), using transthoracic echocardiography (TTE). EF is a highly load-dependent measurement, which varies considerably in CKD patients undergoing haemodialysis. The aim of this pilot study was to evaluate a novel measure of myocardial function, left ventricular twist, which is defined as the 'wringing action of the heart', using speckletracking echocardiography in CKD patients before and after haemodialysis...

INTRODUCTION: Cardio-renal syndrome subtype 4 (CRS4) is a condition of primary chronic kidney disease that leads to reduction of cardiac function, ventricular hypertrophy, and risk of cardiovascular events. OBJECTIVE: Our aim was to understand the mechanisms involved on the onset of CRS4. METHODS: We used the nephrectomy 5/6 (CKD) animal model and compared to control (SHAM). Serum biomarkers were analyzed at baseline, 4, and 8 weeks. After euthanasia, histology and immunohistochemistry were performed in the myocardium...

Background: The association between fibroblast growth factor 23 (FGF23) and coronary artery calcification (CAC) was inconclusive. Recently it was shown that adiponectin modulates renal handling of calcium and phosphorus. We hypothesized that adiponectin plays a role in the effect of FGF23 on CAC and explored whether the association between FGF23 and CAC is modified by serum adiponectin level in chronic kidney disease (CKD) patients. Methods: This cross-sectional study analyzed 1435 predialysis CKD patients from the Korean Cohort Study for Outcome in Patients with CKD cohort...

BACKGROUND: The impact of treating obstructive sleep apnea (OSA) on renal function decline is controversial. Previous studies usually included small samples and did not consider specific effects of different continuous positive airway pressure (CPAP) modalities. The aim of this study was to evaluate the respective influence of fixed and auto-adjusting CPAP modes on estimated glomerular filtration rate (eGFR) in a large sample of patients derived from the prospective European Sleep Apnea Database (ESADA) cohort...

Renal dysfunction may limit the clinical application of NT-proBNP in the diagnosis of heart failure. In general practice, where echocardiography is not readily available, a biomarker for the diagnosis of a heart failure with preserved ejection fraction (HFpEF) would be useful. Since cardiac diseases frequently coincide with renal disease, there is a high need of valid risk stratification methods in patients affected with both. We therefore examined NT-proBNP and another biomarker, Big-Endothelin-1, as a marker of HFpEF in patients with CKD...

BACKGROUND: Long-term persistence of statin therapy provided an ongoing reduction in mortality among patients with and without a known history of CVD, and renoprotective effect on CKD patients. Until now, very few reports are available from China to address the effects of statin therapy in CKD + CAD patients. METHODS: We compared the effects of long-term statin therapy (follow-up time 4 years) in terms of cardiovascular events, all-cause death, and cardiac death among 254 CKD patients with or without CAD...

Before the percutaneous spread, the mortality rate of patients with coronary heart disease not suitable for cardiac surgery was markedly high. This limit has been progressively exceeded with the advent of minimally invasive approaches, which, although was initially intended exclusively for low risk patients, was then employed in complex patients often too compromised to undergo cardiac surgery. Given to the rising of high-risk population, due to an increase of patients with multiple chronic conditions linked to the best care offered, we are witnessing an expansion of the high-risk percutaneous coronary interventions (PCI) population...

BACKGROUND: Left atrial (LA) volume is a predictor of outcome in hypertension. It is unclear whether or not this effect depends on coexisting target organ damage (TOD). PURPOSE: To investigate whether LA volume predicts outcome independently of TOD [left ventricular (LV) hypertrophy (LVH) and/or carotid plaque] in a registry of hypertensive treated patients. METHODS: From the Campania Salute Network registry, we selected 5844 young adult hypertensive patients <65 years old (mean age 50 ± 9 years, 41% women, 8% diabetic) without prevalent CV or valvular heart disease more than mild, with normal LV ejection fraction, stage III or less CKD and available follow-up...

Drug repurposing, is the re-tasking of known medications for new clinical indications. Advantages, compared to de novo drug development, include reduced cost and time to market plus the added benefit of a known pharmacokinetic and safety profiles. Suitable drug candidates are identified through serendipitous observations, data mining, or increased understanding of disease mechanisms. This review highlights drugs suited for repurposing in kidney disease. The main cause of mortality in patients with chronic kidney disease is cardiovascular disease...
