非Q波心肌梗塞的临床和冠状动脉病变特点

CLINICAL AND ANGIOGRAPHIC FEATURES OF NON-Q WAVE MYOCARDIAL INFARCTION

目的：研究非Ｑ波心肌梗塞的特点。方法：将非Ｑ波心肌梗塞和Ｑ波心肌梗塞病例作分析比较。结果：既往有心绞痛史和心肌梗塞者，发生梗塞后心绞痛者，在非Ｑ波心肌梗塞组分别为７１．２％、３７．３％及４９．２％，均显著地多于Ｑ波心肌梗塞组的５４．３％、２２．０％及１７．７％。冠状动脉造影示：有多支血管病变者，血管开放率及侧支循环形成，在非Ｑ波心肌梗塞组有７２．８％、７６．３％及４４％，显著地多于Ｑ波心肌梗塞组的３６．０％、４６．２％及２７．９％。结论：非Ｑ波心肌梗塞在临床和冠状动脉病变方面有某些特点。

Objective:To study features of non-Q wave myocardial infarction. Methods: Comparison of non-Q wave myocardial infarction (NQMI)with Q-wave myocardial infarction(QMI).Results:The pa-tients with NOMI had a significantly higher rate of preinfarction angina(71.2%vs 54.3%),previous myocardial infarction(37.3%vs 22%), multivessel diseases (72.8%vs 36%),post infarction angina (49.2%:vs 17.7%),patency rate of the infarct related artery(76.3% vs 46.2%),collaterals to oc-cluded infarct artery (44% vs 27.9%).In comparison with those of patients with QMI. Conclusion:There are some features in clinical and angiographic aspects of the non-Q wave myocardial infarction.
