What is the outcome after someone survives a heart attack?

Depends...: The outcome will depend on how much damage was done to the heart muscle during the heart attack. If the damage was minimal, there may be no residual symptoms but if there is a lot of damage, there may be shortness of breath with activity or at rest, chest pain with activity, fluid in the lungs or legs, etc. Cardiac rehabilitation can be very helpful after a heart attack so see your doctor!
