Objective To compare the effect of emergency percutaneous transluminal coronanry angioplasty and thrombolytic therapy (PTCA) in acute myocardial infarction (AMI). Methods 52 cases of AMI were treated by emergency PTCA while 58 cases of AMI were treated by thrombolytic therapy, we then compared the clinical effect between two groups both in hospital and the follow-up period. Results In the emergency PTCA group, 3 cases died while 49 cases were successful (success rate 94.2%) and the average staying in hospital was 14.6 d. In this group the left ventricular ejection fraction (LVFT) was 45.5%?4.3%. During the follow-up period of 2～18 months, 3 cases of angina pectoris occurred again and 3 case accepted the treatment of selective PTCA in the emergency PTCA group. In the group of thrombolysis, 8 cases died while 50 cases were successful (the ratio of success rate 86.2%) and the average staying in hospital was 26.4 d. In this group the LVFT was 37.6?6.2. During the follow-up period of 2～18 months, 17 cases of angina pectoris occurred again and 17 cases accepted the treatment of selective PTCA in the thrombolysis group. Conclusion The infarct related arteries (IRA) can be revascularized with emergency PTCA in AMI. The treatment of emergency PTCA can reduce the ratio of sudden death and the days in-hospital ( P

Objective To observe the short term results of emergency PTCA and stent treatment of acute myocardial infarction Methods Analyze the 52 cases of acute myocardial infarction under PTCA and stent treatment in our hospital. Results The reopen rate of infarct related vessels is 100%. One of patients was not able to implant the stent. The post operative situation, ECG and myocardial enzyme are improved obviously without complication. The mean hospitalization period is about 2 weeks. 2 D echo shows EF was normal before discharge. Conclusion The reopen rate of infarct related vessels of AMI under emergency PTCA and stent treatment can short AMI patients′ hospitalization time and improve the myocardial pump function obviously.
