This early-stage trial tests a gene therapy called LX2006 in 8 people with Friedreich's ataxia who also have heart muscle disease. The therapy delivers a healthy copy of the FXN gene to heart cells using a modified virus. The main goal is to check safety over 5 years, while also …

This study was designed to test a new gene therapy called ASP2016 for heart problems caused by Friedreich Ataxia, a rare genetic disease. The therapy aimed to deliver a healthy copy of the faulty gene to help the heart. However, the study was withdrawn before any participants wer…

This study follows 10 people who already received LX2020 gene therapy for arrhythmogenic cardiomyopathy caused by a PKP2 gene mutation. Researchers will monitor them for years to see if the treatment remains safe and continues to help control the disease. The goal is to understan…

This early-stage trial tests a gene therapy called LX2020 for people with a heart condition called arrhythmogenic cardiomyopathy, caused by a change in the PKP2 gene. The study involves 10 adults who already have a defibrillator implanted. The main goal is to see if the treatment…

Researchers are testing whether artificial intelligence can combine ultrasound images with routine health data to track changes in a person's physiology over time. The study enrolls adults with heart, lung, kidney, or blood vessel conditions, as well as healthy volunteers. The go…

This study tests whether a new, more powerful 7 Tesla MRI can better detect scarring and swelling in the heart muscle of people with cardiomyopathy. Researchers will scan 13 adults aged 20-70 to see if the higher-resolution images improve diagnosis. The goal is to see if this adv…

This study monitors heart rate variability in 150 adults with type 2 diabetes who also have heart failure, chronic kidney disease, or both. Participants will wear a 24-hour heart monitor before and after starting a standard SGLT2 inhibitor medication. The goal is to understand ho…

This study gathers health information from children under 18 who have cardiomyopathy linked to mutations in the MYBPC3 gene. Researchers aim to map the disease's natural course, identify risk factors, and measure how it affects quality of life. By reviewing past and future medica…

This early-stage study will check if two different tablet forms of the drug HRS-1893 are processed the same way in the body. Thirty-six healthy adults will take both versions and have blood tests to measure drug levels. The goal is to see if the two formulations are equivalent, n…

This study looks at whether sensors inside implanted heart devices can warn of worsening heart failure. Researchers will track 500 adults with heart failure or cardiomyopathy who have a Boston Scientific ICD or CRT-D equipped with HeartLogic, Sleep Incline, and Apnea Scan functio…

This study examines genetic test results from over 600 people who had acute myocarditis (heart muscle inflammation) confirmed by MRI. Researchers want to find out how common certain gene variants are in this group and whether they are linked to worse outcomes like heart failure o…

This study looks at how inflammation and oxidation (chemical reactions in the body) might damage the heart and lead to heart failure. Researchers are tracking over 1,200 healthy adults aged 40+ (or 18+ with a family history of heart failure) to see if waste products in blood or u…

This study follows about 35 people with dilated cardiomyopathy caused by a BAG3 gene mutation, a condition that weakens the heart muscle. Over three years, researchers will monitor heart function, symptoms, and quality of life using tests like imaging and blood work. The goal is …

This study is for heart failure patients who do not have a specific heart rhythm pattern called left bundle branch block (non-LBBB). These patients often get a device called CRT-D, which combines a pacemaker and a defibrillator, but not everyone responds well. Researchers will fo…

This study looks at whether a smartwatch ECG can predict heart muscle disease (cardiomyopathy) in adult survivors of childhood cancer as well as a standard clinic ECG does. About 1,300 survivors will have both a standard 12-lead ECG and a 30-second Apple Smartwatch ECG. The goal …

This study looks at how sepsis, a severe infection, can cause heart problems in intensive care patients. Researchers will collect data, blood samples, and heart ultrasound images from 330 adults with septic shock. The goal is to find patterns that help doctors better diagnose and…

This study looks at whether a special PET scan can help doctors better predict sudden cardiac arrest in people with heart failure and blocked arteries. About 300 participants who already have a defibrillator will be followed to see if heart nerve damage, heart size, or blood mark…

This study looks at whether a special training program can help family doctors use focused heart ultrasound (FoCUS) to accurately detect common heart conditions like heart failure and valve disease. About 500 patients will get both a family doctor's FoCUS and a cardiologist's ful…

This observational study looks at 165 people with two different types of heart muscle thickening: syndromic/metabolic cardiomyopathy (SMCs) and hypertrophic cardiomyopathy (HCM). Researchers want to see if SMCs patients have worse heart outcomes like death or heart failure, and w…
