Biomarkers to Classify Heart Failure
Heart FailureThe purpose of this study is to evaluate existing biomarkers and see if they can be used to accurately diagnose the etiology of heart failure.

Heart FailureIschemic CardiomyopathyThe aim of the study is to investigate safety and efficacy of intramyocardial implantation of allogeneic mesenchymal stem cells in patients with end-stage ischemic cardiomyopathy undergoing left ventricular assist device implantation.
Study of Renal Denervation in Patients With Heart Failure
Heart FailureCongestive heart failure is a common disorder in which the heart cannot pump enough blood to meet the needs of the rest of the body. Poor sodium handling by the kidneys is a damaging effect of heart failure, and it leads to symptoms of congestion such as shortness of breath or ankle swelling. Recent studies suggest that reducing the nerve activity to a kidney could reduce sodium retention and blood pressure. An improvement in the way the kidneys handle sodium may reduce disease progression and decrease symptoms for heart failure patients.
Dietary Approaches to Stop Hypertension in 'Diastolic' Heart Failure 2 (DASH-DHF 2)
Diastolic Heart FailureHypertensive Heart DiseaseThe purpose of this study is to examine how dietary changes affect the heart and blood vessels in patients with hypertension (high blod pressure) who have a condition called 'heart failure with preserved ejection fraction" (HFPEF). This condition is also known as "diastolic heart failure" or "heart failure with normal ejection fraction", and occurs even though the heart's pumping function is normal.
Safety and Efficacy of Doxycycline in Patients With Non-Ischemic Cardiomyopathy
Non-ischemic CardiomyopathySystolic Heart Failure (NYHA II-III)Non-ischemic cardiomyopathy and heart failure are highly influenced by the presence of systemic inflammation. Doxycycline is a FDA-approved drug to treat bacterial infections which also shows powerful anti-inflammatory effects. In this study we plan to determine the effects of Doxycycline in patients with stable heart failure and non-ischemic cardiomyopathy on peak of aerobic exercise capacity (peak V02) and ventilator efficiency measured with a cardiopulmonary test.
Circulating RNAs in Acute Congestive Heart Failure
Acute Congestive Heart FailureHeart Failure With Reduced Ejection Fraction1 moreThe purpose of this American Heart Association-funded and NIH-funded study is to examine circulating RNAs in the acute CHF setting, how they change with decongestive therapy, and their function in vitro and in vivo. The investigators are testing the hypothesis that ex-RNA levels change significantly during decongestion therapy and can be used as a marker of those individuals who respond to CHF therapy (in terms of cardiac structure or outcome). Additionally, the translational research design allows the investigators to assay the effects of these RNAs on tissue phenotypes in vitro.

Rehabilitation by Eccentric Exercise in Heart Failure Patients
Chronic Heart Failure PatientRehabilitation ProgramAs part of the regular rehabilitation program for chronic heart failure (CHF) patients, the addition of dynamic eccentric endurance (ECC) exercise sessions to the conventional concentric cycling program (CON) would enable greater gains in functional capacity that the CON alone. Furthermore, in the case of severe heart failure, results of conventional exercise rehabilitation remains limited on account of the poor physical fitness and deconditioning. Dynamic ECC has been shown to enhance muscle mass and improve muscle strength in subjects with functional limitations comparable to those in CHF, but to date reports on effects on muscle endurance and overall functional capacity remain scarce or non-existent. Investigator hypothesize that a combination of these two types of training will allow both an improvement in strength and oxidative muscle capacities. These benefits must be objectified at the level of the walking distance covered in 6 min (6-WT).
