摘要
目的评估急性心肌梗塞患者采用急诊PTCA及支架治疗的临床疗效。方法8例急性心肌梗塞患者施行急诊PTCA术，其中4例行冠状动脉内支架植入术。结果所有患者冠脉再通均获成功，TIMI分级均达到皿级，残余狭窄＜20％。所有患者胸痛均在术后2小时内明显缓解；除1例ST段持续增高外，其余7例均在术后2小时下降＞50％；心肌酶峰明显提前，平均距术后1314±4．6小时，CK峰值达2869．0±1050．23．CK－MB峰值为120．92±86.96；术中及术后出现再灌注心律失常5例。结论急诊PTCA和支架植入术可为急性心肌梗塞提供更早期和更安全的再灌注治疗。
Objective To evaluate the clinical results of percutaneous transluminal coronary angioplasty (PTCA) and intracoronarystent for acute myocardial infarction. Methods Authors performed emergent PTCA for 8 cases including 4 stenting in acute myocardial infarction. Results Infarct - related coronary arteries were recanalized and TIMI Ⅲ flow was achieved in all patients. Residual stenosis less than 20 %. Chest pain in all patients were relieved rapidly. The ST segments fell by 50% or more from their elevated levels within 2 hours after PTCA. CK and CK - MB peaks anticipated were after successful PTCA, the values of peaks CK and CK - MB were 2869. 0±1050. 23 and 120. 92±86. 96, respectively. Arrhythmia after reperfusion occurred in 5 cases. Conclusion Both emergent PTCA and intracoronary stent were safe and effective for treating acute myocardial infarction, PTCA can elevate more complete and earlier reperfusion rate of infarct related artery patency.
