Whether heart attack needs bypass surgery should be judged according to the specific circumstances, generally acute heart attack can not choose bypass, can choose stent or thrombolysis and other treatments.
Within 12 hours of acute myocardial infarction, coronary angiography + stent implantation can be preferred to effectively open the blood vessels and restore the blood supply to the myocardium, and the technology is relatively mature, with better therapeutic effects.
In addition to stent implantation, acute myocardial infarction within 6 hours, thrombolysis can also be used to restore myocardial blood supply, which can also save part of the damaged myocardium.
In the case of severe vascular disease, large diffuse myocardial infarction and multiple vessel blockage, coronary artery bypass surgery is required.
