急性无Q波心肌梗塞的临床研究

Clinical Features of Acute Non-Q Wave Myocardial Infarction

本文探讨18例急性无Q波心肌梗塞的临床特点,并与120例急性Q波心肌梗塞作比较。结果表明急性无Q波梗塞较Q波梗塞有显著高的心绞痛史和既往梗塞发生率(27.8％对4.2％,P<0.01)。较低的血清磷酸肌酸激酶(CPK)峰值水平(均值为655.5对886.7U/L,P<0.05)。住院病死率无Q波梗塞低于Q波梗塞,而泵衷、室性心律失常,房室传导阻滞等并发症无显著差别。无Q波梗塞中ST段压低者的CPK峰值高于ST段升高者(774对398U/L,P<0.05),其症状也较严重。

The clinical features of 18 patients with acute non—Q wave myocardial infarction (NQMI) were studied and compared with that of 120 acute MI patients with Q—wave (QMI). Results showed that the incidence of pre—infarction angina and previous myocardial infarction in NQMI patients was higher than in QMI patient (27.8% vs 4.2% ,P<0.01). A lower peak level of serum creatine phosphokinase (CPK) was found in NQMI (655.5 vs 886.7U/L,P<0.05). In—hospital mortality of NQMI patients was less than that of QMI. However, there was no significant difference in the rates of complications, such as pump feilure, ventricular arrhythemias and atrioventricular block, etc. The results also showed that the peak CPK was higher and the clinical symptoms were more severe in NQMI with ST depression than that in those with ST elevations.
