Bypass Surgery Statistics
Heart Bypass Surgery Statistics - 2013 Update
Bypass surgery is a major surgery which is usually done because the coronary arteries that bring blood to the heart muscle have become clogged with plaque, which is basically a build up of cholesterol and fat. When these arteries become blocked it can drastically slow down or stop blood from flowing through the heart's blood vessels. If the patient is fortunate, they will only have chest pain symptoms which gives them the opportunity to go to their doctor to find out what the problem is. However, if the arteries become too clogged, the first symptom could be a heart attack. Either way, it is very possible that bypass surgery is going to be required to relieve the problem. Of course each case will be dealt with differently according to the severity of the blockage and desires of the patient. If the blockage is not so severe that it needs immediate attention, their are other alternatives that can be tried first.
Because of the seriousness of the operation and the bypass surgery complications that can take place during and after the surgery, it is very essential the patient knows all facts and statistics pertaining to the operation. This way, they will be able to make an informed and knowledgeable decision as to whether or not to have the surgery.
Bypass surgery statistics can take on many variables. Age and present health condition are two very important factors that will be closely looked at. Below are a few bypass surgery statistics that you might be interested in knowing.
1 - The risk of death during a coronary artery bypass surgery or before the patient leaves the hospital is approximately 2 - 4 %
2 - Stroke occurs in 1-2% of bypass surgeries. These usually occur, but not always, in the more elderly patients.
3 - In 5 - 10 % of coronary artery bypass grafts, the graft fails and stops flowing blood to the bypassed artery within one year. This usually requires more surgery, with a smaller chance of long term benefits if it happens before full recovery from the first surgery.
Mortality rates may increase slightly for patients in the following categories.
1 - Patients over 70
2 - Those who were already in poor health before the time of the surgery
3 - The disease is in the left main coronary artery.
4 - Patients with diabetes.
5 - Patients with chronic lung problems and smokers.
6 – Patients who are excessively overweight.
7 - Women - Women usually have heart attacks at an older age than men, the average being 70. Because of the age factor, their mortality rates are usually a little larger than their counterparts. Also, they have smaller veins to work with, which can also be a contributing factor.
Long term bypass surgery statistics are as follows:
1 - 5 years after the bypass surgery survival expectancy is at 90%
2 - 10 years after surgery is 85%
3 - 15 years after surgery is 55%
4 - 20 years after surgery is 40%
There are two reasons for the lower rates at 15 years and beyond. The main one is the patient is at an older age, and the other is bypass grafts have a larger likelihood of causing problems after this long a period of time.
5 - Strokes occurred in 5-6% of the operations, but only 2% were severe.
6 - 70% of patients have a full relief from chest pain and are able to resume a normal lifestyle.
7 - 90% of patients have enough significant improvement they are pleased with the procedure.
8 - Approximately 3-4% of patients require exploration for bleeding. There are more risks involved in the second surgery since the body is still weak from the first.
9 - Internal mammary grafts have a higher percentage rate for remaining open for a longer period of time. For this reason, many physicians are turning to this method more often.
Heart disease is a serious medical problem that is the nation's number one killer by far. In most instances it can be avoided by a lifestyle which includes plenty of exercise, no smoking and a healthy diet. If you are under a doctor's care for heart related problems, follow their medical suggestions and diet plan to the fullest extent. We hope these bypass surgery statistics have been of interest or help.
