摘要
观察了106例急性心肌梗塞(AMI)病人心肌梗塞前心绞痛(Pre-IA)和梗塞后心绞痛(PIA)的发生情况。根据有无PIA的发生,将病人分为组Ⅰ(PIA阳性51例)和组Ⅱ(PIA阴性55例)。依据有无Pre-IA的存在,将两组病人进一步划分成4个亚组(ⅠA、ⅠB,ⅡA和ⅡB),然后以Pre-IA的存在来预测PIA的发生,其预测的敏感性为60.00％,特异性为60.66％(X^2=4.43,P<0.05)。
The relation between the occurance of pre-infarction angina (Pre-IA) and post-infarction angina ( PI A)was studied in 106 cases of acute myocardial infarction ( AMI ) . The cases were classified into groups I and II accord-ing to the occurance of PI A and subdivided into I A, IB, II A and IIB according to the presence of Pre-IA, so as to calculate the sensitivity and specificity of Pre-IA in predicting the occurance of PI A (sensitivity
=IA/IA+IIA%), specificity = IIB/IB+IIB % ) . The sensitivity was found to be
60.00% and the specificity 60.66%.
