Blood pressure and death risk in heart failure patients
This study looks at whether average blood pressure (MAP) is linked to survival in people with heart failure. If you are an adult with heart failure symptoms, participating may help doctors better understand how blood pressure affects outcomes.

Can you stop beta-blockers after heart failure recovery?
This trial tests whether people whose heart function has returned to normal after heart failure can safely stop taking beta-blockers. It aims to see if staying on the medication is still needed or if stopping is just as safe.
Paris, IDFAges 18 years+ - NCT06519292Recruiting
Heart side effects from immunotherapy in cancer patients
