What is the average survival rate for a 58 year older man who have a quintuple bypass surgery? Just facts plz?
Prognosis following coronary artery bypass surgery depends on a variety of factor, but successful grafts typically final around 10-15 years. In general, coronary artery bypass surgery improve the chances of survival of patients who are at big risk (meaning those presenting with angina backache shown to be due to ischemic heart disease), but statistically after about 5 years the difference surrounded by survival rate between those who have have surgery and those treated by drug therapy diminishes. Age at the time of coronary artery bypass surgery is critical to the prognosis, younger patients near no complicating diseases have a giant probability of greater longevity. The older tolerant can usually be expected to suffer further blockage of the coronary arteries.
It must also be highlighted that more than four coronary arteries are not usually bypassed unless absolutly necessary, quintaple vehicle five, so five coronary arteries have be bypassed , though i suppose you already knew that.
I am sorry that i cannot provide an accurate survival rate for you, though given the information you hold supplied i would say that the survival rate is big, though prognosis is low. maybe between 3-10 years dependant on how the forgiving chooses their diet and excercise (you should talk to the physician nearly this).
I Hope This Has Helped You, and I Am Sorry About The Results
