目的通过对急性心梗患者临床指标的观察,评价缺血预适应对急性心肌梗死患者预后的影响。方法296例急性心梗患者依发病前24小时内有无心绞痛分为缺血预适应组(IP组)和无缺血预适应组(NIP组)。观察两组间ST段抬高程度、心肌酶峰值、心电图积分、左室射血分数(EF)、室壁瘤、右束支阻滞、休克、心衰的差异。结果IP组ST段抬高的程度(P<0.05)、心肌酶峰值(P<0.05)、心电图积分(P=001)、室壁瘤(P<0.05)、右束支阻滞(P<0.05)、休克(P<0.05)、心衰(P=0.01)的发生机会均低于NIP组。EF(P=0.02)则高于NIP组。结论IP现象可明显改善急性心梗患者的预后。
Objective To evaluate the effect of ischemic preconditioning on the prognosis of patients with acute myocardial infarction by observing the clinical features of patients with acute myocardial infarction. Methods 296 patients with acute myocardial infarction were divided into ischemic preconditioning group (IP group) and ischemic preconditioning group (NIP group) with or without angina pectoris within 24 hours before onset of disease. The difference of ST segment elevation, myocardial enzyme peak, electrocardiogram score, left ventricular ejection fraction (EF), aneurysm, right bundle branch block, shock and heart failure were observed. Results The level of ST segment elevation (P <0.05), peak myocardial enzyme (P <0.05), ECG integral (P = 0.001), aneurysm (P < ), Shock (P <0.05), heart failure (P = 0.01) were lower than the NIP group. EF (P = 0.02) was higher than NIP group. Conclusion IP phenomenon can significantly improve the prognosis of patients with acute myocardial infarction.
