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 efficacy of emergency PTCA and stenting in patients with acute myocardial infarction. Methods 8 cases of acute myocardial infarction patients underwent emergency PTCA surgery, of which 4 cases underwent coronary stenting. Results All patients were successfully treated with coronary recanalization. The TIMI grade reached grade III and the residual stenosis was less than 20%. Chest pain in all patients was relieved within 2 hours after operation. Except for 1 case of ST segment, the remaining 7 cases were reduced by> 50% at 2 hours after operation. The myocardial enzyme peak was significantly earlier than that after operation, with an average of 1314 ± 4 after operation. 6 hours, CK peak reached 2869.0 ± 1050.23. The peak value of CK-MB was 120.92 ± 86.96. There were 5 cases of reperfusion arrhythmia during and after operation. Conclusions Emergency PTCA and stent implantation can provide an earlier and safer reperfusion therapy for acute myocardial infarction.
