摘要
目的:探讨急性前壁心肌梗死急诊经皮冠状动脉介入(percutaneous coronary interventions,PCI)术后1 hST段变化与心功能关系。方法:首次急性前壁心肌梗死行急诊PCI患者49例,比较PCI术前及术后1 h 12导联心电图抬高ST段的总和。按术后ST段回落程度分为两组:ST段回落良好组(A组),ST段回落不良组(B组)。观察患者PCI术前、术后1周心功能分级(Killip分级)。PCI术后3个月行超声心动图检查测量左室射血分数(LVEF)值。结果:两组患者PCI术前Killip分级差异无统计学意义;术后1周KillipⅠ级A组优于B组,差异有统计学意义(P<0.05)。术后3个月LVEF值A组明显优于B组,差异有统计学意义(P<0.01)。结论:PCI术后1 h ST段的变化,可反映心肌再灌注后的心功能情况,对早期临床预后评估和区分高危患者有积极意义。
Objective： To investigate the relationship between ST segment changes and heart function in patients with anterior wall acute anterior myocardial infarction treated by PCI. Methods： Fourty-nine patients with a first anterior wall acute anterior myocardial infarction were enrolled. The extent of the ST segment elevation and resolution in electrocardiograms on admission and one hour after PCI was analyzed. All the patients were divided into two groups. Group A： resolution of ST segment elevation≥50% ;Group B 〈 50%. Killip class were recorded on admission and one week after PCI and LVEF were recorded three months after PCI. Results： Killip class on admission were no statistically significant between A and B. Group A were significantly better than group B in killip class one week, and LVEF were significantly better than group B three months after PCI. Conclusion： ST segment changes one hour after PCI could reflect heart function after myocardial reperfusion. It had clinical practical value for the evaluation of the early prognosis of the disease and distinction of high-risk patients.
