小面积心肌梗死与缺血性心肌病的相关性分析

Correlation analysis of small area myocardial infarction and ischemic cardiomyopathy

1998年1月1日至2001年12月31日896例住院患者中,缺血性心肌病65例,占7.3％(65/896),包括小面积心肌梗死38例,占58.5％(38/65),大面积心肌梗死27例,占41.5％(27/65)。缺血性心肌病为心肌细胞的血供长期不足,冠状动脉有多支病变。小面积心肌梗死,不仅在急性期作血管再通,还应防治它的危险因素。

Totally 896 medical records were statistically analyzed from Jan. 1, ] 998 to Dec. 31 , 2001. There were 65 cases (7. 3%,65/896) of ischemic cardiomyopathy .of which 38 cases (58. 5% .38/65) were myocardial infarction in small area, 27 cases(41. 5% ,27/65) were in large area. The causes of ischemic cardiomyopathy were lack of blood supply in cardiac cells for a long time and pathological changes in branches of coronary artery. If myocardial infarction in small area occurred,the blood vessels should be opened again in acute period, and the risk factors must be prevented and treated.
