It is for ICU patients who were unconscious right after return of heartbeat and meet specific timing and oxygen level requirements.
Genova, GEAges 18 years+ - NCT05537467Recruiting
Music during exercise for people with heart failure
This trial tests whether listening to music while you exercise can improve how well you can exercise when you have heart failure. It is mainly looking for adults who can safely do an exercise test and communicate in English.
Lexington, KentuckyAges 18 years+ - NCT05566483Recruiting
Study long COVID physiology and cardiopulmonary rehab effects
This study looks at how long COVID affects the body and whether cardiopulmonary rehabilitation improves quality of life and physical function. It may help participants better understand their symptoms and see if a structured rehab program improves daily abilities.
Aurora, ColoradoAges 18 years+ - NCT05569122RecruitingPhase 1
Studying an MRI contrast method in mitochondrial muscle disease
This Phase 1 study tests a special MRI approach (using a contrast agent) to better measure changes in muscles in people with mitochondrial diseases. It also includes some healthy volunteers and other critically ill patients to compare results and check safety.
Philadelphia, PennsylvaniaAges 10–60 - NCT05584722Recruiting
Study risk and resilience in pulmonary arterial hypertension
This study looks at how people with pulmonary arterial hypertension (PAH) and certain genetic risks cope and how their bodies respond over time. It may help researchers understand factors linked to better or worse outcomes, and how different people manage the condition.
Nashville, TennesseeAges 15–80 - NCT05595577Recruiting
Personalized exercise program to improve fitness during cancer care
This trial tests whether a tailored, home-based exercise plan can improve exercise capacity (how far and how safely you can be active) in people receiving cancer treatments that may affect the heart. It may help you build safer stamina while monitoring your heart health.
