Heart failure is recognized as one of the most common indications for hospitalization amongst adults aged >65 years in United States with estimated Medicare cost to be 17 billion or more. Chronic heart failure is one of the most life threatening cardiovascular disorder thought to affect nearly six million US population with 600,000 new cases every year. The heart is responsible for perfusion to all vital organs including kidneys and dysfunction in either affects both the vital organs. When dysfunction of heart leads to dysfunction of kidneys or vice versa it is referred to as cardio renal syndrome (CRS). The underlying pathophysiology for CRS has been poorly understood and considered multifactorial. Worsening renal function defined as increase in serum creatinine of >0.3mg/dl from baseline occurs in 20-30% of patients with ADHF and is associated with greater length of hospital stay, hospital readmission and death. A number of interventions have been used including giving diuretics which helps in decongestion and helps the heart pump blood more effectively. Sometimes these therapies are not effective and may even lead to worsening of renal function. In such cases , inotrope agents which increase the contractility of the heart have been used to help pump more blood to vital organs. There have been very few trials assessing the efficacy of these agents for improving kidney function .The investigators aim to assess the renal recovery with two such agents - dobutamine and milrinone in patients with cardiorenal syndrome who are coming with acute decompensated heart failure
In stage 3 chronic kidney disease (CKD) the risk of death due to cardiovascular causes is high and greatly exceeds the risk of progression to end stage renal failure. This high cardiovascular risk is predominantly due to sudden cardiac death and heart failure, manifestations of left ventricular hypertrophy and fibrosis. Aldosterone appears to play an important role in the causation of this myocardial disease both by direct inflammatory and fibrotic myocardial effects and via increased arterial stiffness due to hypertrophy, inflammation, and fibrosis within the media of large arteries. Levels of aldosterone are high in CKD despite sodium overload and treatment with angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) drugs due to the twin phenomena of aldosterone escape and breakthrough. In a previous British Heart Foundation funded study, Birmingham investigators showed that the addition of the mineralocorticoid receptor blocker (MRB) spironolactone to background therapy with ACE inhibitors or ARBs caused reductions in the prognostically important parameters of arterial stiffness and LV mass. Because spironolactone therapy was also associated with significant falls in arterial pressure it remains possible that these effects were mediated simply by blood pressure reduction. In this multi-centre, randomised controlled study, the effects of treatment with spironolactone on LV mass and arterial stiffness in patients with stage 3 CKD on established ACE or ARB therapy will be compared to those of chlortalidone, a control anti-hypertensive agent. Early stage chronic kidney disease is highly prevalent and new, cost effective treatment strategies are required to reduce cardiovascular risk. This study is designed to provide the rationale for a larger study of morbidity and mortality with MRB therapy in early stage CKD.
Patients at moderate and high risk for contrast induced nephropathy (CIN) should receive sufficient hydration before application of contrast to prevent CIN, but hydration could obviously increase the preload for congestive heart failure (CHF) patients. It is important to make an individual hydration protocol for patients with dysfunction of heart and renal to reduce the incidence rate of CIN. This prospective, randomized, double-blind, comparative clinical trial randomly selected 264 patients with estimated glomerular filtration rate, (eGFR) <60 ml/min per 1.73 m2 and CHF undergoing coronary angiography to receive either the convention hydration (n=132) or the central venous pressure (CVP) guided hydration (n=132).
Although the traditional determinant of renal dysfunction in heart failure was suggested as decreased cardiac output and renal hypo perfusion, recent studies have demonstrated the association of persistent systemic venous congestion and kidney dysfunction. Relief of the congestion has demonstrated to improve renal functions in decompensated heart failure. The current trial was set up to investigate the changes of renal venous impedance and renal arteriolar resistivity indices with diuretic therapy, in patients with congestive renal failure. The investigators asked whether measurement of renal venous impedance index or renal arteriolar resistivity index can guide the practice of diuretic therapy.
This is a single-blind, randomised, clinical trial assessing the efficacy of Hydralazine and Isosorbidedinitrate combination (oral agents) in HF patients with renal dysfunction.
Among adult individuals with type 2 diabetes mellitus and at risk for heart failure with impaired relaxation of the heart mildly reduced kidney filtration function (Type 4 cardiorenal syndrome) this trial will evaluate the quantitative impact of 38 weeks of treatment with exenatide extended-release injections versus placebo. on a cardiac biomarker blood test score, cardiac fibrosis seen on magnetic resonance scanning, cardiac strain identified by ultrasonography and strain rate imaging, and a kidney urine biomarker score.
Cardiorenal Syndrome (CRS) is prevalent among end-stage renal disease (ESRD) patients. Recently, its prevalence is rising. There are several different clinical presentations of this syndrome. It has a high rate of morbidity and mortality. The purpose of this study is to find the connection between the heart pathology and its effect on ESRD patients. This will aid in choosing the appropriate medical therapy for these patients, and hopefully, aid in increasing their quality of life, and decrease their morbidity and mortality.
Although inotropes have a favorable effect on central hemodynamics in patients with heart failure, their effect on renal hemodynamics is incompletely defined. The purpose of this study is to evaluate the efficacy of a 75 min intravenous infusion of levosimendan compared to a 75 min infusion of dobutamine on renal hemodynamics and function in patients with chronic heart failure and signs of cardiorenal syndrome. The investigators hypothesis is that patients treated with levosimendan will show greater increases in renal blood flow and glomerular filtration rate (GFR) than those treated with dobutamine.
The purpose of the trial is to investigate the safety and effectiveness of renal denervation for the treatment of chronic heart failure (CHF).
