When there is severe damage to the heart muscle and necrosis of the heart muscle cells, it does not make much sense to do bypass surgery at this point.
Cardiac bypass surgery involves taking blood vessels from other parts of the body and transplanting them to the heart to replace the blood supply function of the diseased heart vessels, thus improving the blood supply to the heart muscle, relieving angina pectoris, and improving the patient’s cardiac function.
Cardiac bypass surgery is used for patients whose symptoms of myocardial ischemia cannot be controlled by medical treatment. It is the first choice for treating the left main stem of the coronary artery and is suitable for patients with multiple coronary artery lesions, coronary artery disease combined with heart failure, and diffuse coronary artery lesions.
When severe cardiac insufficiency exists, surgery is often not tolerated, so myocardial severe damage needs to be carefully evaluated, but most of them are inoperable, so you can consult with a professional physician for advice.
