ABSTRACT
OBJECTIVE:
To compare the diagnostic accuracy of 64-slice multislice computed tomography (MSCT) coronary angiography between female and male patients using conventional coronary angiography as the reference standard.DESIGN:
Diagnostic accuracy study.SETTING:
University hospital. PATIENTS 103 consecutive patients (51 men, 52 women, mean (SD) age 60 (10) years) with known and suspected coronary artery disease underwent 64-slice MSCT. MAIN OUTCOMEMEASURES:
Diagnostic accuracy of 64-slice MSCT to detect obstructive (>or=50% luminal narrowing) stenoses in men and women.RESULTS:
One male and two female patients were excluded from the analysis owing to non-diagnostic MSCT scans as a result of increased heart rate and breathing during the scan. Accordingly, on segmental level, 728/762 coronary segments were of sufficient quality in women (96% (95% CI 95% to 97%)) and 704/723 segments were interpretable in men (97% (95% CI 96% to 98%)). In the remaining 100 patients included in the further analyses, the sensitivity and specificity on a segmental level in women and men were 85% (95% CI 75% to 95%) vs 85% (95% CI 78% to 92%) and 99% (95% CI 98% to 100%) vs 99% (95% CI 98% to 100%), respectively. On a patient level, the sensitivity in women and men was 95% (95% CI 87% to 100%) vs 100%, specificity 93% (95% CI 83% to 100%) vs 89% (95% CI 74% to 100%), positive predictive value 91% (95% CI 79% to 100%) vs 94% (95% CI 86% to 100%), and negative predictive value 96% (95% CI 89% to 100%) vs 100%, respectively.CONCLUSION:
The findings confirm the high diagnostic accuracy of 64-slice MSCT coronary angiography in both male and female patients.
