If Doctor say there is 70% blockage in Heart. What does this mean? Does this mean that it is time to ask for By-pass surgery? Can't these blockage be removed by medicines?
i dont know what does your doctor even mean by saying blockage in heart,
but lets assume if he says blockage in the coronary vessels(heart vessels).. then the criteria for undergoing a heart by-pass surgery is any of the two or both..
1-if there is 3-vessel disease (means that if 3 or more vessels are involved)
2-if there is a large vessel disease.(means that if the main large coronary artery is involved)
if the above criteria is not fulfilled, then ya can undergo angioplasty
