目的　比较经皮冠脉状动脉介入治疗 (PCI)、溶栓治疗对梗死后心绞痛的影响。方法　对 97例首次急性心肌梗死 (AMI)患者分为PCI组、溶栓组及常规治疗组 ,观察治疗后梗死后心绞痛发生情况。结果　PCI组2 2例 ,术后有 2例发生梗死后心绞痛 ;溶栓组 32例 ,有 11例发生梗死后心绞痛 ;常规治疗组 4 3例 ,有 17例发生梗死后心绞痛 ;PCI组术后梗死后心绞痛发生率明显低于溶栓及常规治疗组 (P <0 0 5 ) ,而溶栓及常规治疗组无显著性差异 (P >0 0 5 )。结论　PCI能降低梗死后心绞痛发生率 ,改善患者预后 Objective To compare the effects of percutaneous coronary intervention (PCI) and thrombolytic therapy on post-infarction angina pectoris. Methods 97 patients with AMI were divided into PCI group, thrombolytic group and conventional treatment group. The incidence of post-infarction angina pectoris was observed. Results In the PCI group, there were 22 patients with angina pectoris after infarction in 2 patients and 32 patients in the thrombolytic group. Eleven patients developed angina pectoris after infarction. In the conventional therapy group, 43 patients had angina pectoris after angina pectoris. In the PCI group, The incidence of angina after infarction was significantly lower than that of thrombolysis and routine treatment (P <0.05), but there was no significant difference between thrombolysis and routine treatment (P> 0.05). Conclusion PCI can reduce the incidence of post-infarction angina and improve prognosis
