Objective To observe the efficacy and safety of percutaneous transluminal coronary angioplasty (PTCA) in the treatment of acute myocardial infarction. Methods Twenty-two patients with acute myocardial infarction underwent PTCA within 12 hours after the onset of disease. Twenty-eight of them received intracoronary stents. Anterior descending artery related artery infarction in 12 cases, 8 cases of right coronary artery, circumflex artery in 2 cases. Results Twenty-one cases were successfully operated. In the successful cases, the blood flow recovered to grade 3 with thrombolysis after thrombolytic therapy in TIMI grade 3, TIMI grade 2 in 2 cases and TIMI grade 2 in TIMI 2 grade. One patient died of acute left heart failure and cardiogenic shock. Conclusion PTCA is an effective safety measure for acute myocardial infarction with high success rate and few complications.
