摘要
目的:探讨心肌梗死患者经皮冠状动脉介入治疗(PCI)术后心电图改变与心功能的关系。方法:回顾性分析2014年6月~2016年6月于我院进行经皮冠状动脉介入治疗手术的98例急性ST段抬高型心肌梗死患者的临床资料,按照手术前与手术后1h心电图检查结果,将ST段回落<50%的36例患者设为回落不良组,剩余T段回落≥50%62例设为对照组。对比两组患者手术之前和手术之后12h心肌梗死溶栓试验治疗(TIMI)血流分级,比较术后6个月左室舒张末期内径(LVD)、左室射血分数(LVEF)、二尖瓣环舒张早期峰值运动速度(Em)及二尖瓣环舒张晚期峰值运动速度(Am),计算Em/Am,对比术后3个月6min步行试验。结果:手术前两组心肌梗死患者TIMI血流分级差异无统计学意义,手术后12h对照组心肌梗死患者TIMI血流分级显著优于回落不良组,差异有统计学意义;回落不良组心肌梗死患者术后6个月LVD显著高于对照组,回落不良组心肌梗死患者术后6个月LVEF、Em/Am显著低于对照组,差异有统计学意义;回落不良组心肌梗死患者术后3个月6min步行试验步行距离显著低于对照组,差异有统计学意义。结论:心电图指标是反应心肌梗死患者经皮冠状动脉介入治疗术后心功能恢复状况的重要指标,具有重要临床价值。
Objective To explore the treatment of percutaneous coronary intervention in patients with acute myocardial infarction(PCI) between electrocardiogram and cardiac function after surgery. Methods A retrospective analysis of clinical data from June 2014 to June 2016 in our hospital 98 cases of acute ST elevation myocardial infarction patients after percutaneous coronary intervention surgery, before surgery and in accordance with the after the operation of 1 h ECG examination results, the ST segment of <50% in 36 cases as the fall bad group, the remaining T segment ≥50% 62 patients as control group. Before and after the comparison of two groups of patients with surgery and 12 h surgery treatment of thrombolysis in myocardial infarction(TIMI) flow classification, left ventricular end diastolic diameter is 6 months after the operation(LVD), left ventricular ejection fraction(LVEF), mitral annular peak early diastolic velocity(Em) and mitral annulus peak late diastolic velocity(Am), calculated Em/Am, compared to 3 months after 6 min walk test. Results Before surgery two groups of patients with myocardial infarction TIMI flow grade difference was not statistically significant, 12 h after operation, the control group of patients with myocardial infarction was significantly better than the TIMI flow grade down bad group, the difference was statistically significant; fall bad group of myocardial infarction patients 6 months after LVD was significantly higher than the control group. Fall bad group of myocardial infarction patients 6 months after surgery, LVEF, Em and/Am were significantly lower than the control group, the difference was statistically significant; fall bad group of myocardial infarction patients 3 months after surgery, 6 min walk test walking distance was significantly lower than the control group, the difference was statistically significant. Conclusion ECG index is an important index the recovery of cardiac function in patients after percutaneous coronary intervention in patients with myocardial infarction
