Abstract
Objective To explore the value of clinical diagnosis of the 64-slice spiral CT coronary angiography (64-SCTCA)and serum lipid levels in coronary heart disease (CHD) .Methods Retrospectvely analyzed 90 elderly patients who received 64-SCTCA examination and taken coronary angiography (CAG)within 4 weeks .Based on the probability of CHD Duke model ,the subjects were divided into three groups ,including low ,middle and high risk group ,and 30 patients in each group .Taking CAG as the “gold standard” ,the accuracy of the estimation of 64-SCT-CA and blood lipid level was tested .Results The sensitivity ,specificity ,positive predictive value ,negative predictive value ,accuracy rate of 64-SCTCA in diagnosis of suspected CHD ,were 91 .30% (42/46) ,90 .24% (37/41) ,85 .71%(42/49) ,90 .24% (37/41)and 87 .78% (79/90)respectively .The sensitivity ,positive predictive value and accuracy ate of 64-SCTCA in diagnosis of elderly CHD in low risk group were significantly lower than those in middle and high risk group(P< 0 .05) .TC ,TG ,LDL-C and HDL-C were significantly changed when the coronary artery stenosis (P<0 .05) .Conclusion 64-SCTCA is useful in CHD screening and the blood lipid changes could be useful for diagnosing the degree of coronary artery stenosis .关键词
