How does carvedilol treat congestive heart failure?

Carvedilol is used very often for specific cases of congestive heart failure, high blood pressure, and treatment after a heart attack. Carvedilol is a beta blocker used to treat, but not cure, congestive heart failure. Beta blockers lessen the work that the heart has to do and, by doing so, help maintain a regular heartbeat. In this way, carvedilol helps to lessen the progression and symptoms of congestive heart failure.
