The Relation of Angiographic-Based Coronary Artery Diameters with Gender and Traditional Cardiovascular Risk Factors in Patients with Normal or Mild CAD

Abstract

Background: Several physiological and pathological processes aect the diameter of coronary arteries. It seems that the patholog- ical increase or decrease in the size of coronary arteries is associated with cardiovascular events. Objectives: The aim of this study is to determine the relationship between the diameter of coronary arteries, gender, and traditional cardiovascular risk factors. Methods: In this cross-sectional study, we enrolled 96 patients who underwent coronary angiography at our tertiary research cen- ter. The patients' demographic data, cardiovascular risk factors, and coronary artery diameters were recorded using a digital sliding caliper. Results: Out of 96 patients with a mean age of 56.3 9.8 years, 62 (64.6%) were female. Among cardiovascular risk factors dyslipi- demia was the most prevalent (55 patients or 57.3%) followed by hypertension (45 patients or 46.9%) and smoking (17 patients or 17.7%). The means of the right coronary artery (RCA), left main coronary artery (LMCA), left anterior descending (LAD) and left cir- cumflex (LCX) diameters were 3.27 0.7 mm, 4.35 0.7 mm, 3.5 0.6 mm and 3 0.7 mm, respectively. The female and participants and participants with diabetes had smaller coronary arteries: these dierences have become statistically significant for LMCA and LAD in both groups (in women, the p value for LMCA and LAD were 0.04 and 0.02, respectively, and in those with diabetics, the p value for LMCA and LAD were 0.02 and 0.04, respectively). Conclusions: In our study, female participants and participants with diabetes have smaller coronary arteries. No statistically sig- nificant relationships were found between traditional coronary risk factors and the diameters of coronary arteries.
