Abstract:
Background : Various diagnostic tests, invasive and noninvasive, are used in the diagnosis of coronary artery disease (CAD). Recently, coronary computed tomography angiography (CCTA), being noninvasive and due to its high spatial and temporal resolution, are widely used particularly in patients with low to intermediate probability. Studies on accuracy of CCTA in Iraq are scarce; therefore this study was carried out. Methods : A total of 260 patients were included in this study, they were recruited from the Iraqi Centre for cardiac disease (medical city complex) and Ibn Al - Bitar Cardiac Surgery Center for the period from December 2012 to August 2013. Direct interview for those who referred for CCTA was done and case records of those who did invasive coronary angiography (ICA) were reviewed. Requested information regarding demographic data (age,gender, residence, etc.), history of smoking, alcohol consumption, hypertension, diabetes and present complaints, review of prior tests (electrocardiography (ECG), chest x ray (CXR), echocardiography, treadmill test “TMT”, etc.), referral indication as stated by the physician and outcome data, were filled in questionnaire for each patient.Results : The mean age of patients was 56.7 ± 10.2 with males were predominant (62.3%). There was significant difference between CCTA results with age (p=0.003), left ventricle ejection fraction (LVEF %) (p=0.01), sex (p=0.04) and hypertension (p=0.03). No significant association between CCTA results with diabetes and cholesterol level (P= 0.7, and 0.6 respectively). No significant association was found between TMT findings with CCTA results (p=0.6) or ICA results (p=0.2). Also there was no significant association between ICA findings according to CCTA results (p=0.3). The calculated sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) values for CCTA was (80.7%, 0.0%, 70% and 0.0, respectively). There was significant association between CCTA results with the pretest probability of CAD (p=0.01).Conclusions : Low accuracy figures for CCTA were reported. Guidelines according to Iraqi situation may enhance accuracy
