摘要
４２例患者作了冠状动脉造影（ＣＡＧ），根据临床和ＣＡＧ诊断冠心病者３７例，不符合冠心病者５例。３７例冠心病，ＣＡＧ阳性２８例，敏感性７５．７％，特异性１００％，故阳性者能肯定诊断。同位素心肌显像诊断冠心病敏感性８６．５％，特异性６０％，故阳性意义需结合临床。运动心电图诊断冠心病敏感性５４．１％，特异性８０％，而阴性诊断价值仅为１９％。
Coronary arteriography(CAG)was performed for 42 patients,among them,37 cases were diagnosed as coronary heart disease(CHD)according to the clinical manifestations and CAG,another 5 cases were inconsistent with CHD.Among 37 cases of CHD,28 showed CAG positive,sensitivity:75.3%,specificity 100%,hence the diagnosis of positive cases might be identified.The sensitivity of diagnosis by isotope myocardial visualization was 86.5%,specificity:60%,hence positive diagnosis showd be combined with clinical manlfestations. The sensitivity of exercise electrocardiogram for diagnosing CHD was 54.1%,specificity:80%,while the negative diagnostic value was only 19%,hence the negative result was unable to exclude CHD completely.
