Welcome to Healthcare Magic
You are not clear on your statement. Angiography
is not a corrective surgery, it is just to see which blood vessels of the heart are damaged. If you meant angioplasty
then if you continue to follow bad habits like smoking
, eating fatty food then again high chance of blockage. Angioplasty will not repair all vessels of heart at one time so again if you do not follow proper diet and exercise you will get blockage. Bypass surgery
may be done more than once if required but there is more risk in doing multiple surgeries, better to prevent this by following your doctor's orders, avoid tobacco, paan, eat plenty of fresh fruits and green leafy vegetables and also do exercise as your doctor's advice.
