Objective To analyze the immediate and follow-up results of routine percutaneous coronary intervention (PCI) with ST-segment elevation myocardial infarction (STEMI) over 5 years. Methods From March 1999 to February 2004, 311 consecutive STEMI patients underwent direct PCI. There were 250 males and 61 females, with an average age of 604 (26 to 85 years). 33 cases (106%) were 75 years old. Results The success rate of operation was 99% (30 8/311), no recurrence was 10 6% (25/35), 13 5% (4 2/311) was aortic balloon counterpulsation and 10 cases were used Remote protection device. Thrombosis occurred in 26% (8/30) of the patients. The in-hospital mortality rate was 55% (17/31 1) and the June mortality rate was 68% (17/250). Conclusions Direct PCI has expanded the indications for STEMI treatment and promptly restored the normal blood flow of infarction-related arteries. The survival rate of high-risk patients is high, and the hospitalization time is shortened
