动态脉压与急性心肌梗死预后相关性分析

Correlation Analysis between Prognosis of Acute Myocardial Infarction and Pulse Pressure

目的:探讨急性心肌梗死(AMI)患者动态脉压(PP)与心力衰竭、梗死后心绞痛及病死率的相关性。方法:随机选择AMI患者109例,同时行动态血压(ABPM),以PP≤50mmHg(1mmHg=0.133kPa)(A组,n=44),PP 51～60mmHg(B组,n=35),PP>60mmHg(C组,n=30)分为三组,对其进行分析。结果:随PP增加,心力衰竭、梗死后心绞痛及病死率的发生也明显增加。结论:急性心肌梗死患者中随着PP的增大,其心血管事件的发生率增加,提示预后不良,推测以PP作为观测指标,可预防心血管事件的发生,有助于改善心肌梗死患者的预后。

Objective： To explore the correlation between acute myocardial infarction（AMI） patients dynamic pulse pressure（PP） and heart failure,infarction angina pectoris,mortality.Methods：Random selection of 109 cases of patients with AMI,monitoring ambulatory blood pressure（ABPM）,into three groups：PP≤50mmHg（group A,n=44）,PP 51~60mmHg（group B,n=35）,PP60mmHg（group C,n=30）to analyze.Results：With the PP increasing,heart failure,infarction angina pectoris and mortality increased obviously.Conclusion：The patients with acute myocardial infarction with the increase of Pulse Pressure（PP）increase in the incidence of cardiovascular events,indicates poor prognosis.Conjecture that Pulse Pressure（PP）as observation index,help to prevention of cardiovascular events and improve the prognosis of patients with myocardial infarction.
