急性非Q波心肌梗塞的临床特征

The Clinical Characteristics of Acute Non-Q Wave Myocardial Infarction

作者总结了２３例急件非Ｑ波心肌梗塞（ＮＱＭＩ），与同期１９２例急性Ｑ波心肌梗塞（ＱＭＩ）比较，发现ＮＱＭＩ在发病年龄、性别、易患因素等方面与ＱＭＩ相似；而住院期间心功能较好，严重心律失常发生率较低，心肌酶峰值幅度较小，峰值时间较早，持续时间较短。简要讨论了产生这种差别的可能原因，并指出ＮＱＭＩ梗塞后再发心绞痛，严重心律失常及再梗塞的机会较多，应引起临床重视。

Acute non-Q wave myocardial infarctions(NQMI,23 cases) were analysed as comparized with acute Q wave myocardial infarctions(QMI,192 cases) for the corresponding period.It was found that NQMI was less period.It was found that NQMI resembled QMI in age,sex and susceptible factors,but its cardiac function was better and the incidence of severe arrythmias was less than that of QMI.The peak activity of cardiac enzyme in NQMI was less,peak time earlier and positive duration shorter than that in QMI.The possible causes leading to this differences are discussed.In view of the more incidence of angina pectoris,severe arrythmias and reinfarctions post the first infarction,it is suggested that further active treatment should be taken to improve forward prognosis.
