Introduction: Cardiorenal syndrome (CRS) is a pathophysiologic disorder of the heart and the kidneys whereby acute or chronic dysfunction in one organ may induce acute or chronic dysfunction of the other. In Africa, particularly in Senegal, the incidence of cardiorenal syndrome is not accurately known. This study aimed to assess the prevalence of CRS in the Cardiology Department. Methods: We conducted a retrospective study including all patients with heart failure associated with alteration of renal function, hospitalized in the Cardiology Department between April 2010 and April 2011...

With the adoption of the new definition and classification of cardiorenal syndrome (CRS) and its relevant subtypes, much attention has been placed on elucidating the mechanisms of heart and kidney interactions. The pathophysiologic pathways are of great interest by which acute heart failure may result in acute kidney injury (AKI; type 1), chronic heart failure accelerates the progression of chronic kidney disease (CKD; type 2), AKI provokes cardiac events (type 3), and CKD increases the risk and severity of cardiovascular disease (type 4)...

Since the inception of the Canadian Cardiovascular Society heart failure (HF) guidelines in 2006, much has changed in the care for patients with HF. Over the past decade, the HF Guidelines Committee has published regular updates. However, because of the major changes that have occurred, the Guidelines Committee believes that a comprehensive reassessment of the HF management recommendations is presently needed, with a view to producing a full and complete set of updated guidelines. The primary and secondary Canadian Cardiovascular Society HF panel members as well as external experts have reviewed clinically relevant literature to provide guidance for the practicing clinician...

PURPOSE OF REVIEW: Visceral venous congestion of the gut may play a key role in the pathogenesis of right-sided heart failure (HF) and cardiorenal syndromes. Here, we review the role of right ventricular (RV) dysfunction, visceral congestion, splanchnic hemodynamics, and the intestinal microenvironment in the setting of right-sided HF. We review recent literature on this topic, outline possible mechanisms of disease pathogenesis, and discuss potential therapeutics. RECENT FINDINGS: There are several mechanisms linking RV-gut interactions via visceral venous congestion which could result in (1) hypoxia and acidosis in enterocytes, which may lead to enhanced sodium-hydrogen exchanger 3 (NHE3) expression with increased sodium and fluid retention; (2) decreased luminal pH in the intestines, which could lead to alteration of the gut microbiome which could increase gut permeability and inflammation; (3) alteration of renal hemodynamics with triggering of the cardiorenal syndrome; and (4) altered phosphate metabolism resulting in increased pulmonary artery stiffening, thereby increasing RV afterload...

Left ventricular assist devices (LVADs) are common and implantation carries risk of AKI. LVADs are used as a bridge to heart transplantation or as destination therapy. Patients with refractory heart failure that develop chronic cardiorenal syndrome and CKD often improve after LVAD placement. Nevertheless, reversibility of CKD is hard to predict. After LVAD placement, significant GFR increases may be followed by a late return to near baseline GFR levels, and in some patients, a decline in GFR. In this review, we discuss changes in GFR after LVAD placement, the incidence of AKI and associated mortality after LVAD placement, the management of AKI requiring RRT, and lastly, we review salient features about cardiorenal syndrome learned from the LVAD experience...

BACKGROUND: Heart failure is one of the most important complications of chronic kidney disease (CKD). However, few studies comprehensively investigated left ventricular (LV) structure and function in relation to 2 key CKD measures, estimated glomerular filtration rate (eGFR) and urine albumin/creatinine ratio (ACR). METHODS AND RESULTS: Among 4175 ARIC (Atherosclerosis Risk in Communities) participants (aged 66-90 years during 2011-2013), we quantified the association of eGFR and ACR with echocardiogram parameters of LV mass, size, systolic function, and diastolic function...

Biologically active epoxyeicosatrienoic acid (EET) regioisomers are synthesized from arachidonic acid by cytochrome P450 epoxygenases of endothelial, myocardial, and renal tubular cells. EETs relax vascular smooth muscle and decrease inflammatory cell adhesion and cytokine release. Renal EETs promote sodium excretion and vasodilation to decrease hypertension. Cardiac EETs reduce infarct size after ischemia-reperfusion injury and decrease fibrosis and inflammation in heart failure. In diabetes, EETs improve insulin sensitivity, increase glucose tolerance, and reduce the renal injury...

The interactions between heart and kidney are various and of clinical relevance. Worsening of one organ often influences the function of the other. With NYHA and KDIGO we have classification systems for heart and kidney failure and those should be used for cardiorenal systems as well. Furthermore there is a useful classification system for cardiorenal syndromes itself. Cardiorenal syndrome is a complex illness which should be treated by interdisciplinary medical teams. A key roll in pathophysiology is the renin-angiotensin-aldosteron-system (RAAS)...

INTRODUCTION: Cardiorenal syndrome (CRS) is common in acute heart failure (AHF), and is associated with dire prognosis. Levosimendan, a positive inotrope that also has diuretic effects, may improve patients' renal profile. Published results are conflicting. OBJECTIVES: We aimed to assess the incidence of CRS in AHF patients according to the inotrope used and to determine its predictors in order to identify patients who could benefit from the most renoprotective inotrope...

Epigenetics is defined as the heritable changes in gene expression patterns which are not directly encoded by modifications in the nucleotide DNA sequence of the genome, including higher order chromatin organization, DNA methylation, cytosine modifications, covalent histone tail modifications, and short non-coding RNA molecules. Recently, much attention has been paid to the role and the function of epigenetics and epimutations in the cellular and subcellular pathways and in the regulation of genes in the setting of both kidney and cardiovascular disease...

Despite the development of pharmacological inventions and new nonpharmacological techniques to prevent and treat heart failure (HF), the mortality rate in patients with symptomatic HF remains high. To conquer these difficulties, the pathophysiology of HF should be considered within a wide range of views. Given the diverse mechanisms of HF pathophysiology, renal and cardiac functions have close and complementary interconnections. Recent studies have suggested that communication between the kidney and heart through bidirectional pathways causes significant pathological changes...

Congestion is an integral component of cardiorenal syndrome and portends an adverse impact on the outcomes. Recent studies suggest that congestion has the ability of modulating the interactions between the kidney and the heart in this setting. Peritoneal dialysis (PD) is a home-based therapeutic modality that is not only offered to patients with end-stage renal disease to provide solute clearance and ultrafiltration, but it has also been used in patients with refractory heart failure and fluid overload to help optimize volume status...

Heart and kidney failure continued to be of increasing prevalence in today's society, and their comorbidity has synergistic effect on the morbidity and mortality of patients. Cardiorenal syndrome (CRS) is a complex disease with multifactorial pathophysiology. Better understanding of this pathophysiological network is crucial for the successful intervention to prevent advancement of the disease process. One of the major factors in this process is neurohormonal activation, predominantly involving renin-angiotensin-aldosterone system (RAAS) and arginine vasopressin (AVP)...

Longstanding hypertension ultimately leads to heart failure (HF), and as a consequence most patients with HF have a history of hypertension. Conversely, absence of hypertension in middle age is associated with lower risks for incident HF across the remaining life course. Cardiac remodeling to a predominant pressure overload consists of diastolic dysfunction and concentric left ventricular (LV) hypertrophy. When pressure overload is sustained, diastolic dysfunction progresses, filling of the concentric remodeled LV decreases, and HF with preserved ejection fraction ensues...

Takotsubo cardiomyopathy (TC) is a life-threatening syndrome with ambiguous pathophysiology. The interdependency between heart failure and kidney failure (KF) is well established, but the influence of KF on TC outcome is not known. This single-center cohort from January 2003 to September 2015 consisted of 114 consecutive patients with TC. They were divided into 2 groups according to the presence (n = 32, 29.6%) or absence (n = 76, 70.3%) of KF. The end point of this retrospective study was a composite of in-hospital events, all-cause mortality, rehospitalization due to heart failure, stroke, and recurrence of TC (mean follow-up: 5 years)...

Fabry's disease (FD) is a severe congenital metabolic disorder characterized by the deficient activity of lysosomal exoglycohydrolase alpha-galactosidase, characterized by glycosphingolipid deposition in several cells, such as capillary endothelial cells, renal, cardiac, and nerve cells. As a systemic disease leading to a contemporaneous myocardial and renal dysfunction, FD might be an example of cardiorenal syndrome type 5 (CRS-5). Kidney damage is commonly characterized by proteinuria, isosthenuria and altered tubular function when occurs at the second-third decade, azotemia and end-stage renal disease in third-fifth decade...
