Coronary calcium, as determined by electron beam computed tomography, and coronary disease on arteriogram. Effect of patient's sex on diagnosis.

摘要: Background Coronary artery calcium identified by electron beam computed tomography (EBCT) has potential for noninvasive localization of coronary atherosclerotic disease. However, the effect a patient’s sex on its diagnostic capability not been examined in clinical population. Methods and Results Fifty women 89 men had EBCT scans done an average 1 day after arteriography. Maximum arteriographic percent luminal diameter stenosis any was paired with total score each subject. The (age, 56±11 years [mean±SD]) were older than 47±7 years), but subjects matched indications arteriography extent disease as assessed Sensitivity, specificity, positive negative predictive values nearly identical women, regardless degree highly sensitive to presence (range, 94% 100%), ha...
