脉压差水平对急性心肌梗死预后的影响

Effect of Pulse Pressure on Prognosis of Acute Myocardial Infarction

目的：探讨急性心肌梗死时脉压差水平对其预后的影响。方法：急性心肌梗死患者126例。根据脉压差水平分为2组：正常组：脉压差=30～50mmHg；对照组：脉压差〉50mmHg。对比分析2组梗死后心绞痛、心律失常、心功能情况、心梗面积（CK—MB峰值）、心源性休克及病死率。结果：两组的梗死后心绞痛、心律失常、心功能、心梗面积与病死率相比均有显著性差异。结论：脉压差增大者。发生急性心肌梗死预后不良。

Objective： To investigate the correlation between pulse pressure （PP）and the prognosis of patients with acute myocardial infarction（ AMI） . Method： 126 patients with AMI were divided into two groups： normal group ： PP = 30 - 50mmHg; controlled group： PP 〉 50mmHg. The differences in post - infarction angina, arrhythmia, heart function, infarct size （ CK - MB peak ） and the ratio of death were compared. Result： The occurrence rate of post - infarction angina, arrhythmia, heart function and infarct size （ CK - MB peak ） and the ratio of death in the controlled group were higher than those of the normal group with statistic significance （ P 〈 0.01 or P 〈 0.05 ）. Conclusion： The AMI patients with high pulse pressure have the worse prognosis.
