心肌梗死后早期心绞痛相关因素的探讨

STUDY OF THE FACTORS RELATED TO PREVIOUS ANGINA AFTER MYOCARDIAL INFARCTION

目的探讨梗死后早期心绞痛（PIA）的发生率及其相关因素，防止梗死面积扩展或发生再便，提高急性心肌梗死（AMI）患者存活率。方法分析AMI患者不同性别、年龄、梗死部位及不同心功能状态下PIA的发生率、发作诱因及发作时心电图改变等。结果PIA发生率为20．9％。与梗死部位、梗死面积、心功能状态及高血压有关。结论多支病变的大面积心肌梗死、心功能Ⅲ-Ⅳ级及并发高血压者，PIA发生率明显增高。

Objective To study the incidence and correlative factors of PIA after AMI, and to prevent extensive myocardial infarction or remyocardial infarction. Method Analysis was carried out about PIA incidence, inducing factors and indications of ECG among patients of different sex and age with different infarction position and heart function. Result The incidence of PIA turns out to be 20% in our group, which is closely related to the position and area of myocardial infarction and heart function as well as hypertension. Conclusion The incidence of PIA increases obviously in the patients with AMI extensive and heart function of Ⅲ-Ⅳ degree as well as in patients of hypertension.
