STENOSIS
Patients with STEMI received coronary angiography immediately after admission to the catheter laboratory, with a digital subtraction machine. The coronary angiography was performed by cardiologists in Beijing Friendship Hospital, and all STEMI patients received PCI surgery as soon as possible after admission to open the infarct-related coronary artery. Meanwhile, two interventional cardiologists judged the stenosis of the coronary artery by a double-blind method.
