ABSTRACT
Objective To analyse the rate of coincidence to suspected coronary artery disease (CAD) patient between positive exercise treadmill testing (TET) and coronary angiography (CAG) test.Method Two hundred and sixty-eight chest pain patients positive in TET were performed CAG test,coronary stenosis exceed 50% was diagnosed CAD. Results One hundred and seventy-six patients (65.67%) was diagnosed by CAG, 105 male and 71 female in them. Ninety-two (34.33%) patients was negative in CAG test. The false positive rate of TET between post-menopause patients (30.12%, 25/83 ) andmale patients (28.08%, 41/146) was no significant difference(P > 0.05 ); the difference of false positive rate between pro-menopause patients (66.67%, 26/39) and male patients (28.08% ,41/146) was statistical significance (P < 0.01 ). Conclusions The positive rate of CAG can be greatly improved by screening the chest pain patients though TET before CAG, if the positive in TET performed CAG only. TET false positive rate of pro-menopause female is significantly higher than post-menopause female or male.
ABSTRACT
Objective To study the morbidity rate of and relevance to coronary stenosis in cerebral infarction patients. Methods CT coronary angiography was performed in 112 cases of cerebral infarction after CT cerebral angiography. Multivariate logistic regression analysis was carried out between the clinical data and coronary stenosis. Results In 112 cases receiving CT cerebral angiography, the morbidity rate of coronary stenosis was 46.4%. In 95 cerebral infarction patients, the morbidity rate of coronary stenosis was 51.6%. Multivariate logistic analysis showed that age, hypertension, hyperlipeidemia, significant narrowing of cerebral artery were identified as independent predictors for coronary stenosis. Conclusions Heart examination with 64 row CT should be routinely performed after cerebral angiography in cerebral infarction patients,especially in those with age greater than 65 years, hypertension, hyperlipoidemia and significant narrowing of cerebral artery so as to detect coronary stenosis early.
