BACKGROUND: Cardiorenal anemia syndrome (CRAS) is an evolving global epidemic associated with increased morbimortality and cost of care. The management of patients with CRAS remains a challenging undertaking worldwide and the lack of evidence-based clinical guidelines adds to the challenge. We aimed to explore the prevalence and survival rates of heart failure patients with CRAS in Tanzania. METHODS: We screened 789 patients and consecutively recruited 463 who met the inclusion criteria...

Takotsubo cardiomyopathy (CT) is a syndrome characterized by an acute and transient left ventricular dysfunction, electrocardiographic abnormalities suggestive of acute coronary syndrome, chest pain and/or dyspnea, left ventricular mid-apical segments akinesia and normal coronary angiography. It is mainly observed in postmenopausal women after an intense physical or mental stress. The course is usually favourable but sometimes severe complications occur. The recurrence rate is 2-10%. We present the case of a recurrence of CT in a female, 79 years old, with hypertension, diabetes, chronic kidney disease (CKD) stage 3 who was admitted to the emergency room for dyspnea and vomiting...

The pathologic crosstalk between the heart and kidney is known as cardiorenal syndrome (CRS). While the specific mechanisms underlying this crosstalk remain poorly understood, CRS is associated with exacerbated dysfunction of either or both organs and reduced survival. Maladaptive fibrotic remodeling is a key component of both heart and kidney failure pathogenesis and progression. G-protein coupled receptor (GPCR) signaling is a crucial regulator of cardiovascular and renal function. Chronic/pathologic GPCR signaling elicits the interaction of the G-protein Gβγ subunit with GPCR kinase 2 (GRK2), targeting the receptor for internalization, scaffolding to pathologic signals, and receptor degradation...

The syndrome of heart failure involves complex pathophysiologic mechanisms and is associated with extremely high-morbidity, mortality and economic costs. This growing global epidemic has diverse etiologies and is fundamentally characterized by dyshomeostasis between heart and kidneys, leading to development and progression of the cardiorenal syndrome. Excessive and sustained sympathoexcitation has emerged as a single prominent factor involved in the structural and functional dysfunction of multiple organ systems during this disease...

INTRODUCTION: Diabetes is known to be associated with chronic kidney disease (CKD) and cardiovascular disease (CVD) independently. Type 2 cardiorenal syndrome (CRS), a recently defined syndrome, is characterized by a primary renal failure that progressively leads to cardiac dysfunction. The effect of diabetes on cardiorenal syndrome has not been explored in a multi-ethnic population. In this retrospective secondary analysis the hypothesis was tested if diabetes modifies the effect of CVD on CKD...

Cardiorenal syndrome type 1 causes acute kidney injury but is poorly understood; animal models and diagnostic aids are lacking. Robust noninvasive measurements of glomerular filtration rate are required for injury models and clinical use. Several have been described but are untested in translational models and suffer from biologic interference. We developed a mouse model of cardiorenal syndrome and tested the novel near-infrared fluorophore, ZW800-1, to assess renal and cardiac function. We performed murine cardiac arrest and cardiopulmonary resuscitation followed by transthoracic echocardiography, 2- and 24h later...

PURPOSE OF REVIEW: Acute decompensated heart failure (ADHF) is one of the biggest challenges in the management of chronic heart failure. Despite the advances in medical and device therapy, high readmission and mortality rates continue to be a burden on healthcare systems worldwide. One of the strongest predictors of adverse outcomes in ADHF is renal dysfunction, referred to as cardiorenal syndrome (CRS) type 1. This review discusses some of the recently introduced findings related to the pathophysiology, diagnosis, and management of this disorder...

BACKGROUND: Proenkephalin A (PENK) and its receptors are widely distributed. Enkephalins are cardiodepressive and difficult to measure directly. PENK is a stable surrogate analyte of labile enkephalins that is correlated inversely with renal function. Cardiorenal syndrome is common in acute heart failure (HF) and portends poor prognosis. OBJECTIVES: This study assessed the prognostic value of PENK in acute HF, by identifying levels that may be useful in clinical decisions, and evaluated its utility for predicting cardiorenal syndrome...

BACKGROUND/AIM: The renal arterial resistance index (RRI) is a Doppler measure, which reflects abnormalities in the renal blood flow. The aim of this study was to verify the value of RRI as a predictor of worsening renal function (WRF) in a group of chronic heart failure (CHF) outpatients. METHODS: We enrolled 266 patients in stable clinical conditions and on conventional therapy. Peak systolic velocity and end diastolic velocity of a segmental renal artery were obtained by pulsed Doppler flow, and RRI was calculated...

BACKGROUND: Although there are some animal models for biomarkers of contrast-induced acute kidney injury (CI-AKI), for cardiorenal syndrome (CRS) and for acute renal failure, the interplay between CI-AKI and CRS has yet to be evaluated. Insight into the pathogenesis of CRS is urgently needed from animal models in order to foster the discovery and implementation of novel biomarkers for this disease. Specially designed animal models for type 1 and 3 CRS, particularly CI-AKI, have not yet emerged...

Hypertensive rats with chronic kidney disease (CKD) exhibit enhanced gamma-aminobutyric acid (GABA)B receptor function and regulation within the nucleus tractus solitarii (NTS). For CKD with hypertension, renal denervation (RD) interrupts the afferent renal sympathetic nerves, which are connecting to the NTS. The objective of the present study was to investigate how RD improves CKD-induced hypertension. Rats underwent 5/6 nephrectomy for 8 weeks, which induced CKD and hypertension. RD was induced by applying phenol to surround the renal artery in CKD...

OBJECTIVES: To determine whether the risk of cardiovascular mortality associated with cardiorenal syndrome subtype 1 (CRS1) in patients who were hospitalized for acute coronary syndrome (ACS) was greater than the expected risk based on the sum of its components, to estimate the predictive value of CRS1, and to determine whether the severity of CRS1 worsens the prognosis. METHODS: Follow-up study of 1912 incident cases of ACS for 1 year after discharge. Cox regression models were estimated with time to event (in-hospital death, and readmission or death during the first year after discharge) as the dependent variable...

OBJECTIVE: Chronic intermittent renal replacement therapy(RRT) is an alternate method of decongestion for patients presenting with diuretic-resistant, end-stage heart failure(HF) and cardiorenal syndrome. The optimal method of vascular access has not been confirmed. This study investigated the 6-month outcomes of patients with end-stage HF after the creation of arteriovenous communications (AVC) compared with other means of RRT. METHODS: We treated 40 patients with chronic, intermittent, ambulatory RRT, of whom 15 (37...

In the United States, more than 50 million people have blood pressure at or above 120/80 mm Hg. All components of cardiorenal metabolic syndrome (CRS) are linked to metabolic abnormalities and obesity. A major driver for CRS is obesity. Current estimates show that many of those with hypertension and CRS show some degree of systemic and cardiovascular insulin resistance. Several pathophysiologic factors participate in the link between hypertension and CRS. This article updates recent literature with a focus on the function of insulin resistance, obesity, and renin angiotensin aldosterone system-mediated oxidative stress on endothelial dysfunction and the pathogenesis of hypertension...

Cardiovascular disease and major cardiovascular events represent main cause of death in both acute and chronic kidney disease patients. Kidney and heart failure are common and frequently co-exist; this organ - organ interaction, also called organ cross-talk led to well-known definition of cardiorenal syndrome (CRS). Here we'll describe cardiovascular involvement in patients with acute kidney injury (AKI). Also known as type-3 CRS or acute reno-cardiac CRS, it occurs when AKI contributes and/or precipitates development of acute cardiac injury...
