Left ventricular failure

This study tests a new heart pump called BrioVAD for people with severe heart failure that doesn't get better with standard treatments. The pump uses magnetic levitation to help the heart pump blood. About 780 adults will get either the BrioVAD or an existing pump to see if the n…

This pilot study tests whether heart failure patients whose heart function has returned to normal can safely stop taking two medications (sacubitril/valsartan and dapagliflozin or empagliflozin). Eighty adults whose heart failure was caused by a treatable condition like a heart v…

This study tests whether the drug vericiguat can help children with heart failure caused by a weak left heart chamber. About 342 children aged 1 month to 18 years will receive either vericiguat or a placebo for 16 weeks. The main goal is to see if the drug lowers a key heart stre…

This study tests a small device called C-MIC that is implanted without open-heart surgery to help people with heart failure. It includes 22 adults with weak heart pumping (ejection fraction between 25% and 50%) despite standard medications. The device delivers microcurrents to th…

This study tests the long-term safety of finerenone, a medicine that may help the heart pump better by reducing inflammation and scarring. It is for children from birth to 18 years old with heart failure and a weak left ventricle. All participants will take finerenone along with …

This study is testing a new device called the BrioVAD, a mechanical heart pump for people with severe, advanced heart failure that doesn't get better with standard treatments. The goal is to see if the pump is safe and helps people live longer and feel better. About 60 adults wit…

This phase 3 study tests whether finerenone, a drug that blocks inflammation and scarring in the heart, can improve heart function in children aged 6 months to 18 years with heart failure and left ventricular systolic dysfunction. About 111 participants will receive either finere…

This study compares two common heart procedures—bypass surgery (CABG) and stenting (PCI)—in 358 people with weak hearts (ejection fraction 40% or less) and multiple blocked arteries. The goal is to see which approach leads to better survival, fewer heart attacks or strokes, and i…

This early study tests a device called ContraBand™, which is implanted in the lung arteries to reduce pressure on the heart. The goal is to see if it's safe and can improve exercise ability and symptoms in people with left-sided heart failure. About 55 adults with moderate to sev…

This study is testing a new mechanical heart pump, called the Corheart 6, in 53 people with advanced heart failure. The pump is implanted to help the heart pump blood. Researchers want to see if it is safe and effective at keeping patients alive, either until they can get a heart…

This study tests whether dapagliflozin, a drug already used for diabetes and heart failure, can help the heart heal better after a heart attack. About 450 adults who have had a heart attack and have weak heart pumping will receive either the drug or a placebo for 6 months. The go…

This study tests whether a newer, two-step hybrid ablation procedure works better than standard catheter ablation for people with persistent atrial fibrillation (a type of irregular heartbeat) and heart failure. About 120 participants will be randomly assigned to one of the two p…

This study tests whether a daily oral iron supplement (sucrosomial iron with vitamin C) can improve exercise ability and quality of life in people with chronic heart failure and iron deficiency. About 60 participants will receive either the iron supplement or a placebo for 24 wee…

This early-phase study tests whether injecting lab-grown heart cells (made from human embryonic stem cells) can safely improve heart function in 18 adults with chronic heart damage from a past heart attack. Participants receive one of three doses via a catheter, and researchers m…

This study tests whether a newer pacing method called left bundle branch pacing (LBBP) works better than the standard biventricular pacing for people with chronic heart failure and reduced pumping ability. About 60 adults with heart failure and a specific electrical delay in the …

This study will check how well a heart surgeon's visual estimate of the heart's pumping ability matches the more precise measurement from an ultrasound (TEE) during open-heart surgery. About 70 adults having planned heart surgery with a heart-lung machine will take part. The goal…

This study trains non-expert staff in GP practices to perform quick heart ultrasounds on people 65 and older. The goal is to find hidden heart valve disease or heart failure early, especially in diverse communities. Researchers hope this approach can reduce emergency hospital vis…

This study looks at how menopausal hormone therapy (MHT) affects the heart's ability to pump blood. Researchers will compare heart function in postmenopausal women who use MHT and those who don't. The goal is to understand the role of the nervous system in these changes. About 50…

This pilot study at Mayo Clinic will use cardiac MRI scans to examine how the heart's main pumping chamber changes in people with severe mitral regurgitation before and after valve repair surgery. The goal is to see if this approach can help identify patients at risk of developin…

This study looks at how a specific type of heart failure (left ventricular diastolic dysfunction) affects short-term results after heart surgery, especially in women. Researchers will track 1,000 patients undergoing cardiac surgery, comparing men and women to find differences in …

This study uses artificial intelligence to analyze electrocardiograms (ECGs) and identify people at high risk for developing left ventricular dysfunction, a type of heart muscle weakness. Researchers will then see if giving standard heart medications—like ACE inhibitors, beta-blo…

This study looks at whether simple, non-invasive skin tests can detect early signs of heart disease by measuring how well small blood vessels work. Researchers will study 900 people aged 60-75, comparing skin blood flow measurements with detailed heart scans. The goal is to find …

This study is looking at children ages 7 to 18 who have been newly diagnosed with high blood pressure. Researchers want to understand how certain hormones in the body, like angiotensin-(1-7), may contribute to damage in the heart, kidneys, and blood vessels. Over two years, they …

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…
