How long does a typical heart by-pass surgery remain effective?

Answer 1

Coronary artery bypass graft (CABG) has been replaced by Off-pump CABG in almost all surgical clinics throughout the country. In this operation, transplantation of internal mammary artery (which runs longitudinally beneath the breast bone), so that its end is buried directly in the heart muscle, has improved circulation in many cases. Those who have done this operation claim good results in a large majority. In CABG, saphenous vein in the thigh is utilized as a free graft from the aorta to a portion of the coronary artery that is beyond the point of arteriosclerosis, obstruction or thrombosis.
The success of CABG depends upon the damage that has been caused to the heart following the myocardial infarction and prior to the surgery. [The thinning of the wall due to myocardial infarction may lead to cardiomegaly (enlargement of heart), distortion of valves and subsequent regurgitation of blood from ventricles to auricles.] Lifestyle changes are necessary -- such as not smoking, improved diet, regular exercise, and treating high blood pressure and high cholesterol. If the lifestyle of the patient is not changed, pedal edema and cardiac asthma may occur. In certain cases, the graft may be blocked by a thrombus affecting pumping efficiency of the heart. Having another serious medical condition (such as diabetes, peripheral vascular disease, kidney disease, or lung disease) may also affect the heart. In the majority of people who have the surgery, the grafts remain open and functioning for 10 to 15 years.

Answer 2

it all depends on how the person cares for themselves after the procedure..if they return to the same activities that led to the need for the surgery,( smoking,high fat diet,dormant lifestyle) then the effects won't be good for long...if a person does change their lifestyle for the better then theres no reason why they can not remain effective for the duration of the persons life

about 10 years. My fathers lasted 15, they didn't redo the bypass tho they used stints after that and they didn't have to use open heart surgery they went up thru the artery in his groin it was actually pretty cool cause he got to stay awake and watch on the TV.
