Does congestive heart failure happen quickly?
Does congestive heart failure happen all of a sudden, or does the patient know before the doctor diagnoses him that he has a heart problem?
Congestive heart failure doesn't usually happen all of a sudden. The typical symptoms are fatigue and trouble breathing, which can go on for a long time and gradually get worse. That's how congestive heart failure typically occurs, but it could come on suddenly after an acute event like a heart attack or viral cardiomyopathy (infection of the heart).
