[Percutaneous transluminal coronary angioplasty for acute myocardial infarction].

Objective: To investigate the indication, optimal time, feasibility, and safety of percutaneous transluminal coronary angioplasty (PTCA) for the treatment of acute myocardial infarction (AMI).

Methods: The direct PTCA and follow-up on 76 Q-wave type AMI patients were performed.

Results: There were 79 occlusive coronary arteries in 76 patients. Seventy-eight patients were successfully reperfused and the overall successful rate was 98.7%. Of them 77 were TIMI III and 1 was TIMI II. One case was not reperfused. After the reperfusion, one had an acute reocclusion and one was dead. None of them had the acute cardiac dysfunction and recurrence of AMI after the PTCA.

Conclusion: The direct PTCA is feasible and safe of AMI. For the patients whose AMI time is over 24 hours and still with obvious chest pain after the treatment of medicine, the direct PTCA may also be an alternative therapy.
