A member asked:

Can ejection fraction of 35% after heart attack... in general be improved by cardiac excersize, or meds only. is ef based only on amt of damage?

EF: Ejection fraction is a measure of contractile function. It is related to the state of the muscle and the preload and afterload of the heart. When decreased by heart attack, it may improve a bit with healing, or revascularization; sometimes a bit by meds but large improvements are not usual.

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.
