急性不壁,正后壁心肌梗塞高危亚组的临床分析

ANALYSIS OF HIGH RISK SUBGROUP PATIENTS WITH ACUTE INFERIOR AND/OR POSTERIOR MYOCARDIAL INFARCTION

本文以心电图变化为依据,分析急性下璧和(或)正后璧心肌梗塞高危亚组的临床特点。结果表明,本组住院期间严重并发症多,死亡率高,近期预后较差,临床应采取积极有效的治疗措施。

Seventy-four cases with acute inferior and/or posterior myocardial infarction were studied. They were divided into two groups, group A and B, according to the reciprocal changes of ST segment in anterior precordial leads (V1-V6) during acute phase. In auhgroup B2, ST segment in anterior precordial leads did not return to base line simultaneously with the inferior ST elevation and were still depressed>0.2mV and SGOT peaks and QRS scores were significantly higher (P<0.01) than those in the other groups. All cases in subgroup B2 had serious complications, higher mortality and worsened prognosis during staying in the hospital. Subgroup B2 was called the high risk subgroup. The study suggests that high risk patients should be under close ohservation in order to take more active and effective measures to improve the prognosis.
