I agree with cindy707, with this caveat... When I had my first heart attack
, I decided that exercise and diet alone would solve my problems and rejected prescription drugs and followed a holistic approach. My EF was in the same 30% range. Following the holistic approach, my EF dropped lower and had two additional heart attacks. After my seventh stent I mixed in conventional medications but continued weight loss and exercise, and I haven't had a heart attack since.
