Abstract

Objective: To compare high resolution computed tomography coronary
angiography with conventional coronary angiography.
Methodology: This comparative study was carried outon 55 patients fulfilling the
inclusion criteria.They had already done CT angiography, then they underwent
invasive coronaryangiography at catheterization lab of Cardiology department,
Lady Reading Hospital Peshawar for segmental analysis of all four vessels i.e. left
main stem(LMS), left anterior descending artery (LAD), left circumflex(LCX) and
right coronary artery (RCA).
Results: Mean age was 53 ±10.168 (46-80), most 39(72%) were males while
16(28%) were females. In this study,sensitivity for the left main stem was 60%,
specificity 100%, PPV 100% and NPV 91%. For Proximal LAD, sensitivity was
100%, specificity 78 %, PPV 90 % and NPV was100%. For Mid LAD sensitivity
was 100%, specificity 93%, PPV75% and NPV 100%. For distal LAD, sensitivity
was 100%, specificity 92%, PPV55% and NPV 100%. In Proximal LCX, sensitivity
was 100% , specificity 87% , PPV 85% and NPV was 100%. For the Mid LCX the
sensitivity was 100%, specificity 95%, PPV 75% and NPV was 100%. For distal
LCX, the sensitivity was 100%, specificity 94%, PPV 62% and NPV 100 % . In
Proximal RCA, sensitivity was 100%,specificity 71%, PPV 66% and NPV 100%.
For Mid RCA sensitivity was 100%, specificity 92 %, PPV 94 % and NPV 100
%.For distal RCA, sensitivity was 75%, specificity 100%, PPV 100% and NPV
96%.
Conclusion: MDCTA angiography has potential diagnostic accuracy in the
detection of CAD as compared to conventional angiography.
