【摘要】：目的探讨急性ST段抬高型心肌梗死冠状动脉介入溶栓治疗(PCI)术后心电图(ECG)指标变化和心功能的临床关系。方法回顾性分析该院2014年1月至2015年12月收治的86例行PCI手术的急性ST段抬高型心肌梗死患者的临床资料,根据其术前及术后1 h ECG检测结果,ST段回落50%的29例患者为研究组,其余57例为对照组,术后3个月行6 min步行实验及超声心动图检查,比较两组患者检查结果。结果术前两组患者心肌梗死溶栓试验治疗(TIMI)血流分级无明显差异(P0.05),术后12 h均有明显改善,且对照组优于研究组(P0.05);研究组左室射血分数(LVEF)、二尖瓣环舒张早期峰值速度(Em)/舒张晚期峰值速度(Am)及6 min步行距离显著低于对照组,左室舒张末内径(LVD)显著高于对照组(P0.05)。结论 ECG指标是反映急性ST段抬高型心肌梗死PCI术后心功能恢复的良好指标,在临床应用上具有重要作用。
[Abstract]:Objective to investigate the relationship between changes of ECG and cardiac function after coronary intervention thrombolysis in patients with acute St segment elevation myocardial infarction (St segment elevation myocardial infarction). Methods the clinical data of 86 patients with acute ST-segment elevation myocardial infarction treated with PCI from January 2014 to December 2015 were analyzed retrospectively. According to the results of ECG examination before and 1 hour after operation, 29 patients with St segment retreating 50% were selected as the study group. The other 57 cases were used as control group. 6 min walking test and echocardiography were performed 3 months after operation, and the results were compared between the two groups. Results there was no significant difference in blood flow grade between the two groups in thrombolytic therapy of myocardial infarction before operation (P 0.05), and there was significant improvement at 12 hours after operation. Compared with the control group, the left ventricular ejection fraction (LVEFV), the peak velocity of mitral annulus in early diastolic phase and the walking distance of 6 min in the control group were significantly lower than those in the control group, and the left ventricular end-diastolic diameter (LVD) was significantly higher than that in the control group (P 0.05). Conclusion ECG is a good index to reflect the recovery of cardiac function after PCI in patients with acute ST-segment elevation myocardial infarction, and it plays an important role in clinical application.
