冠状动脉旋磨术治疗老年冠状动脉重度钙化病变的效果

目的探讨冠状动脉旋磨术治疗老年冠状动脉重度钙化病变的效果。方法入选2014年1月至2016年1月期间在华西医院心血管内科治疗的冠心病患者80例。采用随机数字表法,将所有患者分为两组:旋磨组(n=40)和非旋磨组(n=40)。观察两组患者的手术情况及围术期并发症等。结果旋磨组的手术即刻成功率显著高于非旋磨组(92.50%vs70.00%),差异具有统计学意义(P0.05)。与治疗前相比,旋磨组和非旋磨组患者术后的左室射血分数均显著增加,差异具有统计学意义(P0.05)。旋磨组术中2例发生心室颤动,1例发生心脏骤停,未发现急性心肌梗死、心源性死亡、冠脉穿孔等并发症;非旋磨组未发生围术期并发症。结论冠状动脉旋磨术治疗老年冠状动脉钙化重度病变效果较好。

Efficacy of coronary rotational atherectomy in treatment of elderly severe coronary artery calcification

Objective To investigate the efficacy of coronary rotational atherectomy in the treatment of severe coronary artery calcification in the elderly. Methods Eighty patients with coronary heart diseases admitted in our department from January 2014 to January 2016 were recruited in this study. They were randomly divided into 2 groups, rotational atherectomy group (n=40) and non-rotational atherectomy group (control, n=40). Their operation and perioperative complications were observed and compared between the 2 groups. Results The immediate success rate was significantly higher in the rotational atherectomy group than in the control group (92.50% vs 70.00%, P<0.05). The postoperative left ventricular ejection fraction were significantly increased when compared with that before treatment (P<0.05). There were 2 cases of ventricular fibrillation and 1 case of cardiac arrest in the rotational atherectomy group, but no acute myocardial infarction, cardiac death, coronary perforation or other complications were found. No perioperative complication was observed in the control group. Conclusion Rotational atherectomy has good efficacy in the treatment of severe coronary artery calcification in the elderly.
