Impairment of cardiac function causes renal damage. Renal failure after heart failure is attributed to hemodynamic derangement including reduced renal perfusion and increased venous pressure. One mechanism involves apoptosis and is defined as cardiorenal syndrome type 1. Erythropoietin (EPO) is a cytokine that induces erythropoiesis under hypoxic conditions. Hypoxia inducible factor 1 alpha (HIF-1α) plays a regulatory role in cellular response to hypoxia. Protective effects of EPO on heart, kidney and nervous system are unrelated to red blood cell production...

BACKGROUND: Signs and symptoms of volume overload are the most frequent reason for hospital admission in acute heart failure (AHF). Diuretics are mainstay treatment, but their optimal type and dose regimen remain unclear, especially in patients with cardiorenal syndrome. METHODS: This prospective study aimed to include 80 AHF patients with volume overload and cardiorenal syndrome. Through a 2 × 2 factorial design, patients were randomised towards (1) combinational treatment with acetazolamide and low-dose loop diuretics versus high-dose loop diuretics; and (2) open-label oral spironolactone 25 mg OD given upfront versus at discharge...

The cardiorenal syndrome has been defined as a situation in which therapy to relieve congestive symptoms of heart failure is limited by a decreased renal function. The resistance to conventional diuretic treatment makes difficult managing these patients. Tolvaptan, a selective vasopressin-2 receptor antagonist, has been used successfully in adults with this pathology but the experience with children is very limited. A five-year-old girl with renal failure waiting for a heart transplant is presented. Tolvaptan (0...

Cardiorenal syndrome (CRS) describes the concurrent failure of cardiac and renal function, each influencing the other. Malnutrition and cachexia frequently develop in patients with heart failure or kidney failure. However, no information is currently available on the prevalence of malnutrition in CRS patients. We studied CRS patients admitted to an internal medicine ward during a 5-month period and evaluated their clinical characteristics and nutritional status. Malnutrition risk was assessed by using the validated screening tool NRS-2002 whilst body composition was assessed by bioimpedance analysis and muscle function was measured by handgrip (HG) strength...

BACKGROUND: Peritoneal dialysis (PD) is one of the corner stones of renal replacement therapy and should be strongly considered if preemptive kidney transplantation is not available. SUMMARY: There are several initiatives that may help the growth in the use of PD around the world. First, PD is an underused and valuable option in patients with heart failure and the chronic cardiorenal syndrome, especially in those with frequent hospitalizations despite optimal medical therapy...

Hypertension is common in patients with chronic renal disease particularly those with diabetes. It is sometimes resistant to the pharmacological treatment. The mineralocorticoid receptor antagonist spironolactone may be indicated here. The mineralocorticoid receptor antagonists have a Class 1, Level A indication for the treatment of heart failure with reduced ejection fraction. There is an associated risk of worsening renal function and of hyperkalemia which does not hinder their clinical benefit. However, an appropriate biological monitoring is warranted, along with potential dose adaptations...

Resolvins are innate, immune responsive, bioactive mediators generated after myocardial infarction (MI) to resolve inflammation. The MI-induced bidirectional interaction between progressive left ventricle (LV) remodeling and kidney dysfunction is known to advance cardiorenal syndrome (CRS). Whether resolvins limit MI-induced cardiorenal inflammation is unclear. Thus, to define the role of exogenous resolvin D (RvD)-1 in post-MI CRS, we subjected 8-12-wk-old male C57BL/6 mice to coronary artery ligation. RvD1 was injected 3 h after MI...

Worsening renal function and azotemia in patients with heart failure (HF) are strongly associated with disease severity and poor prognosis. Increasing interest in this correlation led to the description and classification of cardiorenal syndrome (CRS). We evaluated the role of neutrophil gelatinase-associated lipocalin (NGAL) in the early detection of CRS in dogs with HF. Ten healthy dogs and 31 dogs admitted with HF were included in our study. NGAL and troponin-I were measured on samples collected on the day of admission; creatinine was measured on admission and again on day 7...

Inter-organ crosstalk plays an essential role in the physiological homeostasis of the heart and other organs, and requires a complex interaction between a host of cellular, molecular, and neural factors. Derangements in these interactions can initiate multi-organ dysfunction. This is the case, for instance, in the heart or kidneys where a pathological alteration in one organ can unfavorably affect function in another distant organ; attention is currently being paid to understanding the physiopathological consequences of kidney dysfunction on cardiac performance that lead to cardiorenal syndrome...

Functional magnetic resonance (MR) imaging of the kidneys has gained interest recently, especially in the detection of early changes in acute kidney injury or to predict progression of chronic kidney disease (CKD). The application of these methods to cardiorenal syndrome (CRS) is novel. CRS is widely accepted as a complex clinical problem routinely faced by clinicians. In this issue, Chang et al ( 1 ) present their preliminary experience applying blood oxygen level-dependent (BOLD) MR imaging to the kidneys in mice with experimental myocardial infarction...

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...
