Coronary Artery Dimensions, Anatomic Findings and Distributions of Southern Turkey

Abstract

Major coronary artery (CA) diameters, including those of the left main coronary artery (LMCA) are important predictors of the success of revascularization therapies. In the international literature, there are some studies regarding angiographic CA findings in various populations. Our aim was to assess the LMCA and major CA diameters with Quantitative Coronary Analysis (QCA) software, and to report their distributions of East Mediterranean Turkish population. Materials and Methods: In 2016, 1139 patients who had normal CA were retrospectively included. Angiographic views were evaluated and CA diameters were measured using QCA. Results: There were 528 women (46.4%), and 611 men (53.6%) in our study group. The mean age was 57.3±11.4 years. Hypertension frequency was 46.3% (527 patients), and the frequency of diabetes mellitus was 12.2% (139 patients). There were 497 smoking patients (43.6%). The intermediate artery was seen in 183 (16.1%) patients. There were 106 (9.3%) rudimentary right CAs, 56 (4.9%) rudimentary circumflex arteries, and 1 (0.1%) rudimentary left anterior descending artery. Proximal and distal LMCA diameters and their circular areas were significantly greater in men. When coronary artery diameters were indexed to body surface area, there was no difference between genders. Conclusion: Our work is the largest scale study regarding quantification of coronary artery diameters of East Mediterranean Turkish population. Our findings are similar to those of Caucasians in general. We believe that the international literature will become richer with studies containing information regarding proximal and distal diameters, lengths, and areas of LMCA in various populations
