80% of the blocked heart vessels cannot be stented and can be treated with medication or coronary artery bypass grafting.
Severe stenosis of coronary artery needs stent implantation, but some patients can’t implant stent due to severe calcification, thin blood vessels or tortuous blood vessels, so they can be given medication and coronary artery bypass grafting treatment.
1. Drug therapy: patients with severe coronary artery disease need to take oral aspirin, atorvastatin and other drugs under the guidance of a physician to prevent platelet aggregation and stabilize arterial plaque, patients with angina pectoris can be given nitrate drugs at the same time, and if the heart rate permits, metoprolol can be added to reduce myocardial oxygen consumption.
2. Coronary artery bypass grafting: It is a surgical treatment, which can increase the blood supply to the diseased area through coronary artery bypass grafting, and it is an option for patients who cannot be treated with stenting in the clinic.
Patients who can not be placed in the stent should be given basic drug therapy, and at the same time, cardiac surgery consultation can be requested to clarify whether there is an indication for coronary artery bypass grafting, and coronary artery bypass grafting treatment can be given when necessary.
