. Basically… Remedy for a heart attack is a complicated question. First it would have to be diagnosed by a procedure called a cardiac catherization or angiogram. This is where the doctor injects a radio-opaque die in the femoral (thigh) veins to determine the size of the lesion. There are also other tests like EKG which is a electrical signal of how the heart is functioning, or a CK-MB which is blood test for a heart attack. Thrombolytic therapy uses drugs to dissolve a clot. The most radical is a Coronary Artery Bypass Graft. This procedure uses arteries from your leg or other part of the body and is grafted on the heart bypassing the block artery. Which procedure is right for a patient is determined by the cardiologist based on the severity of the clot.
