Exercise,time: In general, there will be some improvement in ef over the 6-8 week following a heart attack. This is due to some shrinkage of the scar, and compensation by the undamaged part of the heart. Recovery will be improved with regular aerobic exercise, such as in a cardiac rehab program. Medications will definitely also help the process, and are a recommended part of the treatment.
