May I know life expectancy for those who went through coronary artery bypass surgery?

Providing that they make conscious efforts to maintain healthy life. Using vein for this surgery affect the patient's life expectancy?

    Typically, the saphenous vein from the leg and the left internal mammary artery (LIMA) are used for the bypass. Veins used either have their valves removed or are turned around so that the valves in them do not occlude blood flow in the graft. LIMA grafts are longer-lasting than vein grafts, both because the artery is more robust than a vein and because, being already connected to the aorta, the LIMA need only be grafted at one end. For this reason, the LIMA is usually grafted to the left anterior descending artery (LAD), which supplies the left ventricle, the part of the heart that pumps oxygenated blood around the body. Alternatively, an artery such as the radial artery from the arm, may be used in place of a vein. This is believed to prolong the life of the grafts but this has yet to be proven.

    Prognosis following CABG depends on a variety of factors, but successful grafts typically last around 10-15 years.

    I had sextuple bypass surgery for 10 blockages 22 years ago in 1993 at age 36 at Hoag Hospital, Newport Beach, CA. They did something right as I am still on that first set of veins and artery. Last angiogram 13 years after surgery showed all bypasses 100% open. I'm lucky since I have normal to low blood pressure and of course I do my part by not smoking, eating fairly healthy overall, exercise and am not overweight.

    My grandfather had a triple bypass (they used veins from his leg). This was at least 10 years ago, and he's still going strong. But, he takes his meds, goes to his appointments, exercises daily, and eats healthy. Way to go grandpa!

    It depends on the patency of the grafts and the left ventricular function. If both are fine, it is excellent. In general arterial graft (LIMA) has better patency rates than vein graft.
