Filter by:The purpose of this study is to evaluate the selective cytopheretic device on the immune dysregulated state of congestive heart failure(CHF) with CRS and to assess the benefit of the device to improve cardiovascular and renal function. The study will enroll eligible patients in the ICU with acute on chronic systolic heart failure and worsening renal function due to cardiorenal syndrome while awaiting LVAD implantation. In this study patients who are eligible and agree to participate will receive treatment with the SCD. The treatment will be for 6 hours a day up to 6 days. Additionally, participants will have additional study procedures and be evaluated to determine if their kidney function improves enough to undergo LVAD implantation.
The prospective single-center study investigates the association between changes in Doppler-derived renal venous flow and cardiac surgery-associated acute kidney injury (CSA-AKI).
Following cardiac surgery, right ventricular function may be altered leading to increase central venous pressure and decrease in renal blood flow. The investigator's standard care includes use of diuretic to avoid interstitial fluid accumulation. The aim of the study is to assess cardiac and renal function before and after depletion by using diuretics
ITISHOPE4HF is a randomized controlled trial of telerehabilitation in a heart failure population. The goal is to evaluate if a home-based telerehabilitation project can increase physical activity in heart failure patients. Patients will be provided telerehabilitation or advice on physical activity (standard care).
Predictive value of renal venous flow profiles for adverse outcomes in patients with right heart failure
The goal of this trial is to evaluate whether subantimicrobial-dose of doxycycline (20mgBID) will affect serum and urine biomarkers of fibrosis in patients with pre-dialysis chronic kidney disease.
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
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.
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.
