This study is testing a new type of biological heart valve that features an 'easy change' system, designed to make future replacements simpler. Researchers will implant these valves in 500 people with aortic valve disease and track complications like blood clots, infections, and …

This study tests two ways to treat a slow heart rate caused by overactive nerves, without using a permanent pacemaker. One method uses freezing (cryoablation) and the other uses burning (radiofrequency) to calm the nerves. Sixty adults aged 18 to 60 with symptoms like fainting or…

This study tests a new way to reduce heart damage after a severe heart attack (STEMI). Doctors will cool the heart's arteries during the standard procedure to open blocked vessels. The goal is to see if this cooling prevents further injury and improves heart function. The trial i…

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 is testing whether a special heart scan (SPECT) can detect problems in the heart's smallest blood vessels, called microvascular dysfunction. Researchers will measure how the heart muscle moves and pumps blood in 75 people with and without coronary artery disease. The g…

This study looks at whether giving intravenous iron (Ferinject) to heart failure patients with low iron can improve their quality of life and walking ability. About 100 hospitalized adults with a specific type of heart failure (HFpEF) will receive either iron infusions plus diet …

This study looks at medical records of 1,000 older heart patients in Russia to see if they were prescribed potentially harmful medications during the COVID-19 pandemic. Researchers will use a medical database to count how often these risky prescriptions happened and check for dan…

This study is a registry that collects information from all suspected heart attack cases in Tomsk, Russia. It aims to track how many people die within 28 days and one year after a heart attack. No new treatments or drugs are being tested—just observation and data gathering.

This study looks at tiny structures inside heart cells called mitochondria in people with heart failure and clogged arteries. Researchers will take small heart tissue samples during bypass surgery and compare them with blood tests. They want to see if damaged mitochondria are lin…

This study follows 80 adults who had coronary bypass surgery to see how developing pneumonia in the hospital affects their heart and lung health over the next year. Researchers will compare patients who get pneumonia with those who don't, using blood tests, heart and lung functio…

This study follows 160 heart failure patients who are scheduled for coronary artery bypass surgery. Researchers want to see if measuring a substance called GDF-15 in the blood before surgery can help predict who will have serious heart problems in the next year. The study does no…

This study uses an online survey to understand how medication use, self-medication, and other factors affect healthy aging in adults 18 and older. Researchers will look at drug interactions, polypharmacy (taking five or more medications), and genetic factors in a subgroup. The go…
