Detection of Coronary Artery Diseases: Comparative Study of Multidetector Computed Tomography Angiogram (64 slice scanner) and Conventional Angiogram.

ABSTRACT

Methods: It was cross sectional comparative study conducted in National Institute of Cardiovascular Diseases and Bangabandhu Sheikh Mujib Medical University. Total 80 patients were included in the study who underwent MDCT and coronary angiogram. Results: The sensitivity, specificity, positive predictive value, negative predictive value and accuracy or efficacy for single vessel disease were 87.5%, 96.4%, 91.3%, 94.7% and 93.75% respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy or efficacy for double vessel disease were 84.0%, 94.5%, 87.5%, 92.85% and 91.25% respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy or efficacy for triple vessel disease were 69.5%, 91.22%, 76.19%, 88.13% and 85.0% respectively. Conclusion: Coronary angiography is a promising technology that already appears to have high performance to assess patient base, vessel base and segment base sensitivity, specificity, positive predictive value, negative predictive value and accuracy in detecting coronary artery stenosis.
