| Abstract

The advent of multi-slice computed tomography (CT) technology has provided a new promising tool for non-invasive assessment of the coronary arteries. However, as the prognostic outcome of patients with normal or non-significant finding on computed tomography coronary angiography ( CTCA) is not well-known, this study was aimed to determine prognostic value of CTCA in patients with either normal or non-significant CTCA findings. This retrospective cohort study was performed on patients who were referred for CTCA to the multi-detector CT scan unit. From 527 patients with known or suspected coronary artery disease( CAD )who had undergone CTCA at least 1 year previously, data of 465 patients who had normal (no stenosis, n=362) or non-significant (stenosis <50 percent of luminal narrowing, n=103) CTCA findings were analyzed, and prevalence of cardiac risk factors and major adverse cardiac events (MACE) were compared between these group. In addition, correlation between these factors and number of involved coronary arteries was also determined. After a mean follow-up duration of 13.11+ - 4.63 months, except 3 patients who died of non-cardiac problems, all 465 participants were alive. Prevalence of MACE was 0 percent and 3 percent in normal CTCA group and non-significant group respectively . After controlling for age, no correlation was found between the number of involved coronary vessels and the prevalence of MACE (p-value: 0.57). A normal CTCA could be associated with extremely low risk of MACE over the first year after the initial imaging, whereas non-significant obstruction in coronary arteries may be associated with slightly higher risk of MACE.
