Active clinical trials for "Heart Failure"

The Study Purpose is to demonstrate the superiority of optimized remote patient management compared to optimized standard care in the management and prognosis of heart failure, in the prevention of recurrent atrial tachycardia or atrial fibrillation episodes and in the reduction of inappropriate shock therapies. The remote care allows early intervention in terms of drug therapy adjustment and cardiac resynchronization therapy (CRT-D) device reprogramming.

The Latin America CRT Study is a prospective, multicenter, interventional post-market release study conducted in Latin America. The geography includes Puerto Rico and the Caribbean, Mexico and Central America, and South America.

The Counter Pulsation Device (CPD) System 'Symphony' is intended to provide counter pulsation therapy for up to thirty (30) days to patients with chronic heart failure who have persistent worsening of their condition despite optimal medical therapy. Patients will be in New York Heart Association (NYHA) Class IIIb or IV heart failure and have exhausted all medical or surgical options.

The objective of this study is to evaluate the prevalence of sustained ventricular and supraventricular rhythm disorders in patients implanted with a CONTAK RENEWAL TR2 ventricular resynchronization therapy (CRT) device

Patients with reduced left ventricular function are at an increased perioperative risk and often need prolonged postoperative treatment on intensive care units. A significant portion of these patients require postoperative pacing. Right ventricular pacing has been shown to be hemodynamically deleterious The aim of this study is to determine which biventricular pacing after cardiac surgery, in patients with reduced left ventricular function (EF≤ 45%), is hemodynamically favourable.

We evaluated the preventive impact of vaccination on subsequent death events in 117 severe congestive heart patients requiring ventilator support without endotracheal intubations and aggressive medical therapy. They were randomly allocated in a single-blind manner as a unique intramuscular influenza vaccination or as controls. The first primary outcome evaluated at 6 months follow-up - cardiovascular death - occurred in 3% of the patients in the vaccine group Vs 17% in controls (p=0.022). The composite end point occurred in 33% of the patients in the vaccine group Vs 74% in control group, p = <0.001.

Coronary artery disease (CAD, cholesterol plaque buildup in the heart arteries) is the most common cause of left ventricular systolic dysfunction (weakening of the heart muscle). The standard test to find coronary artery disease is coronary angiography. This test is highly accurate but is invasive and carries a small risk of complications. This study investigates ultrasound of the carotid (neck) arteries as a screening test for severe coronary artery disease as a cause of left ventricular systolic dysfunction. It is hypothesized that carotid ultrasound will have excellent negative predictive value for severe CAD.

The study is designed to study the utility of 123I-mIBG as a diagnostic imaging agent to predict cardiac outcomes in subjects with heart failure and in comparison to subjects without cardiovascular disease.

The purpose of the ReLINQuish study is to characterize the relationship between subcutaneous impedance and hemodynamic measurements in patients with heart failure. Additionally, the relationship between changes in subcutaneous impedance and other physiologic parameters during acute decompensated HF events will be characterized.
