摘要(Abstract)：

目的探讨完全血运重建(CR)是否能够改善急性ST段抬高心肌梗死患者(STEMI)运动后心率恢复(HRR)及相关影响因素。方法回顾性分析2010年7月至2014年10月就诊于北京大学第三医院心内科接受急诊经皮冠状动脉介入治疗(PCI)且符合入选条件的STEMI合并多支病变(MVD)患者151例(MVD组),其中77例患者接受了完全血运重建(CR)为CR组,74例接受不完全血运重建(IR)为IR组;将89例单支病变(SVD)患者设为对照组(SVD组)。所有患者均于发病30 d内行心肺运动试验(CPET)评估运动停止1 min、2 min的心率恢复、HRR相对值(%HRR)、心率储备等指标。同时收集患者的临床特点、生化指标、超声心动图指标、冠状动脉造影结果等资料,比较CR组、IR组、SVD组3组间上述指标的差异。结果 240例患者中男212例(88.3%),平均年龄(55.5±10.9)岁。21例(8.8%)患者运动后伴有缺血性ST段改变,但3组间比较差异无统计学意义(P>0.05)。3组患者HRR2、%HRR2、心率储备差异均有统计学意义(P<0.05),其中与SVD组比较,IR组HRR2[(40.1±11.6)次/min比(46.1±13.8)次/min,P=0.005]、%HRR2[(42.4±14.7)比(50.2±21.6),P=0.007]、心率储备[(60.7±15.4)次/min比(67.2±14.6)次/min,P=0.010]均显著偏低;CR组HRR2[(44.7±14.0)次/min比(40.1±11.6)次/min,P=0.036]、%HRR2[(46.7±17.2)比(42.4±14.7),P=0.048]、心率储备[(66.0±17.0)次/min比(60.7±15.4)次/min,P=0.039]显著高于IR组,而SVD组与CR组比较差异无统计学意义(P>0.05)。CR组、SVD组HRR1亦高于IR组,但3组间比较差异无统计学意义(P>0.05)。对MVD患者行多元线性回归后提示CR是HRR2的独立影响因素,而与%HRR2、心率储备无独立相关。结论 CR可能有助于改善急性心肌梗死患者自主神经功能。
