Abstract

Background: The coronary artery diseases are public health problem responsible for millions of deaths yearly all over the world. Earlier detection of these diseases is essential in treatment and prevention of high morbidity and mortality. The aim of this study was to find out the accuracy of detecting significant coronary stenosis by computerized tomography angiography versus conventional coronary angiography.

Materials & methods: Present study was retrospective cross-sectional study implemented in Cardiac center at Erbil city, Kurdistan region-Iraq in duration of six months from 1st of April to 31st of September, 2023 on sample of 100 patients with suspected coronary artery disease. Saved records of patients who were admitted in cardiac center hospital were reviewed regarding conventional angiogram with computerized tomography angiography in radiology department of this hospital.

Results: There were no significant differences between CTA findings and conventional angiography findings regarding coronary stenosis detection, severity of stenosis, LAD stenosis, CX stenosis, RCA stenosis, LM stenosis, diameter of stenosis and area of stenosis (p>0.05). There was a highly significant relationship between CTA stenosis detection and conventional angiography stenosis detection (p<0.001) with validity findings of CTA in diagnosis of stenosis were (75.9% sensitivity, 80.4% specificity and 78% accuracy).

Conclusions: The computed tomography angiography has an acceptable accuracy in diagnosis of coronary artery diseases as compared to conventional invasive angiography.
