Dilated cardiomyopathy

This study tested whether using a heart MRI to find scar tissue can help decide which people with mild-to-moderate heart failure should get a defibrillator (ICD) to prevent sudden cardiac death. About 449 adults with a weakened heart pump (ejection fraction 36-50%) and scar tissu…

This study tested two different methods of pacing the left side of the heart in people with severe heart failure. The goal was to see if pacing from inside the heart (endocardial) works better than the usual method from outside (epicardial). Only 6 adults took part, and the main …

This study tested an oral drug called ifetroban in 46 males aged 7 and older with Duchenne muscular dystrophy (DMD). The goal was to see if the drug is safe and can help prevent or treat heart problems, which are a leading cause of death in DMD. Participants received either ifetr…

This study tested a small device that delivers gentle electrical currents to the heart in 70 people with severe heart failure. Participants received either the device plus standard medications or medications alone. The main goal was to see if the device improved the heart's pumpi…

This study tested whether MitoQ, a drug that targets cell energy centers, can improve heart function in 53 people with dilated cardiomyopathy. Participants took MitoQ or a placebo for several months while researchers measured heart energy levels and pumping ability using MRI scan…

This study explores whether a cardiac MRI can safely and effectively gather the same heart pressure and flow measurements normally obtained through right heart catheterization, a more invasive procedure. Researchers will attempt to perform the catheterization inside the MRI machi…

This study tested a new MRI technique that lets patients breathe normally during heart scans, instead of holding their breath. Researchers used special software (GRICS) to remove motion artifacts. They compared the free-breathing images to standard breath-hold images in 30 adults…

This pilot study tested whether a portable 6-lead ECG device, paired with an artificial intelligence algorithm, can help screen first-degree relatives of people with dilated cardiomyopathy (a weakened heart muscle). The goal was to see if this mobile approach could detect reduced…

This study tested whether a personalized exercise program, guided by an Apple Watch, can improve fitness and well-being in people with dilated cardiomyopathy, a condition that weakens the heart. 300 adults aged 18-65 with the condition took part over 13 months. The main goal was …

This study looks at whether natural substances in the blood, called cardiac biomarkers, can help doctors manage children with cardiomyopathy—a disease of the heart muscle. The goal is to see if these blood tests could be a less invasive alternative to echocardiograms or MRIs for …

This study looks at how inherited heart rhythm problems (like Long QT Syndrome) and heart muscle diseases (like Hypertrophic Cardiomyopathy) affect the quality of life and physical activity of children aged 6 to 18. Researchers will compare 107 children with these conditions to 1…

This study collected information from over 15,000 people hospitalized with cardiomyopathy, a heart muscle disease. Researchers looked at how much these hospital stays cost and what the money was spent on. The goal was to understand the real-world financial impact and help manage …

This completed study looked at 262 people with dilated cardiomyopathy, a condition where the heart muscle is weakened and enlarged. Researchers used a special MRI technique (T1 mapping) to measure scarring (fibrosis) in the heart. They wanted to see if the amount of scarring coul…

This completed study looked at 60 heart failure patients with reduced pumping function and dangerous heart rhythms. Researchers compared metabolic profiles between those with ischemic (blocked arteries) and non-ischemic (other causes) heart disease. By analyzing blood samples, th…

This study looked for Fabry disease, a rare genetic disorder, in 409 Portuguese adults with unexplained heart muscle diseases. Researchers tested patients with different types of cardiomyopathy to see how many actually had Fabry disease. The goal was to better understand how comm…

This completed study looked at how the beta-blocker carvedilol helps the heart pump better in people with heart failure. Fifty-five patients with weak hearts took the highest tolerated dose for six months. Researchers measured changes in heart muscle contraction to understand the…

This completed study looked at 258 people with different types of cardiomyopathy (a disease of the heart muscle) to see if special imaging could predict stroke risk. Researchers used echocardiograms and MRI scans to measure blood flow in the heart and check for silent brain infar…
