Summary

This trial found that in patients without reduced heart function or heart failure, beta-blockers did not have a significant impact on cardiovascular risk after CABG surgery.

Who is the study for?
The trial is for adults over 18 who've had coronary artery bypass graft surgery, are on beta blocker therapy at their 6-8 week check-up, and have a heart pumping function of at least 45%. It's not for those with past severe heart failure, recent abnormal heart rhythms or strokes around the time of their surgery.
What is being tested?
This study examines whether patients who've undergone bypass surgery but don't have high-risk features like severe heart failure can safely stop taking beta blockers—a common heart medication—without negative effects on their health.
What are the potential side effects?
While specific side effects aren't listed for stopping beta blockers in this context, generally reducing these medications can potentially lead to increased heart rate, blood pressure changes, and risk of chest pain or even a heart attack if done too quickly.
