老年非心脏手术围手术期的心肌缺血

作者对７０例老年普通外科手术患者围手术期的心肌缺血情况进行分析，结果表明（１）冠心病，高龄（〉７５岁）患者与术中心肌缺血有显著相关性（Ｐ〈０．０５）；（２）术中及术后心动过速（〉１００／ｍｉｎ）、血压升高（收缩压〉２１．３ｋＰａ）与ＳＴ段下降有显著相关性（Ｐ〈０．０５）；（３）牢冠患者围手术期心肌缺血主要表现为无症心状缺血；（４）术后４８ｈ内心肌梗死发生的高危期。

Perioperation myocardial ischemia in elder patients undergoing noncardiac surgery

We studied 70 cases of noncardiac surgery and analysed the data of perioperative myocardial is-chemia,The results showed:In noncardiac surgical elder patients with coronary artery disease(1)mvocar-dial ischemia during ope-ration is related to coronary artery dise-ase(P<0.005)and age over 75(P<0.05);dial ischemia during operation is related to coronary artery disease(P<0.005)and age over 75(P<0.05);(2)the persistently elevated heart rate and blood preaxure during postoperative period are associated with ECG ST segrnent ehange(P<0.05);(3)perloperative myocardial ischemia is clinically silent throughout the entire period and therefore difficult to detect;(4)the time of 48 h after surgery is a high risk period of my-ocardial infarction.
