Carvedilol vs. Metoprolol Succinate for Heart Failure with ICD

This study, called CARVTOP-ICD, is comparing two common heart medications, carvedilol and metoprolol succinate, in people with heart failure with reduced ejection fraction (HFrEF) who also have an implantable cardioverter defibrillator (ICD). An ICD is a small device placed in your chest to help regulate your heartbeat and prevent sudden cardiac death. The study wants to see if one medication is better at preventing events like needing ICD therapy, being hospitalized for heart problems, or cardiovascular death. You could join if you are 18 or older, have an ICD for HFrEF, and are currently taking metoprolol succinate but are willing to switch to carvedilol. The study aims to enroll 2,000 participants and will follow them for up to 3 years.

Study design
This is a randomized study, meaning you would be assigned by chance to either continue metoprolol succinate or switch to carvedilol. It is an open-label study, so both you and your doctor will know which medication you are taking. The study plans to include 2,000 participants.
What's involved
You would be followed for up to 3 years, with regular check-ups that include looking at your ICD, checking how well you're taking your medication, and asking about your quality of life.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for up to 3 years to track the first occurrence of ICD therapy, cardiovascular hospitalization, or cardiovascular death.

  • Composite Endpoint: First Occurrence of ICD Therapy, Cardiovascular Hospitalization, or Cardiovascular DeathUp to 3 years

    This composite outcome measures the time to first occurrence of one of the following events: (1) ICD therapy (appropriate or inappropriate shocks or anti-tachycardia pacing), (2) hospitalization due to cardiovascular causes, or (3) cardiovascular death. Only the first event occurring during the study period will be counted per participant.
