Heart failure, systolic

This study tests a device called Aortix, a small pump placed in the main artery, to help remove excess fluid in people hospitalized with acute heart failure who are not responding well to diuretic medications. About 320 participants will be randomly assigned to receive either the…

This early-stage trial will test a single dose of a new drug called LY3971297 in 90 people with two types of heart failure: preserved ejection fraction (HFpEF) and reduced ejection fraction (HFrEF). The main goal is to see if the drug is safe and what side effects occur. Particip…

This study compares two common heart procedures—bypass surgery (CABG) and stenting (PCI)—in 754 people with severe coronary artery disease and a weak heart pump. The goal is to see which approach better prevents death, stroke, heart attacks, or repeat procedures over 5 years. Par…

This study tests two water pills—acetazolamide and metolazone—added to standard diuretics in 320 adults hospitalized with acute decompensated heart failure. The goal is to see which drug clears fluid buildup faster and more safely, reducing hospital stays and complications. Parti…

This study tests whether pacing the heart to mimic the speed of a workout can improve heart function in people with heart failure. Fifty-two adults with a weak heart and an implanted defibrillator will receive either active pacing or a sham (fake) pacing for 6 weeks. Researchers …

This study looks at how extreme head-down positioning (Trendelenburg) and gas inflation during robotic surgery affect the heart's ability to pump blood. Researchers will monitor 80 patients—some with normal heart function and some with heart failure—using a special probe and brai…

This observational study looks at how fitness level relates to bacteria in the mouth and blood flow to muscles. Researchers will collect mouth swabs, saliva, and blood samples, and measure exercise capacity in 70 adults with heart failure, peripheral artery disease, or overweight…

This study is tracking 1,000 adults with psoriasis to see how their skin condition relates to heart disease. Researchers will use blood tests and heart imaging to find early signs of heart problems. The goal is to better understand why people with psoriasis have higher rates of h…
