Sex Differences in Risk Factors Profile and Angiographic Pattern of the Patients Undergoing Coronary Angiography


Introduction: Coronary artery disease (CAD) is a costly problem and its presentations and risk factors may differ by sex. Objective: This study aimed to evaluate the risk factors profile and angiographic pattern of the patients undergoing coronary angiography, according to their gender. Methods: This cross-sectional study was conducted on 741 patients who were referred for coronary angiography from March to August 2018 at Imam Ali cardiovascular center, western Iran. Using a checklist, we collected the demographic, clinical, biochemical, and lab parameters and angiographic findings in these patients. Also, differences between groups were compared using Chi-square and independent t-tests. Results: Women were different from men in terms of the prevalence of hypertension (71.7% vs. 45.3%), diabetes mellitus (34.9% vs. 17.8%), and hypercholesterolemia (26.4% vs. 17.1%). Whereas, men were more likely to be smoker (28.7% vs. 0%) and obese (42.09±16.68 vs. 29.12±4.72). Total Cholesterol and Triglycerides were higher in women compared to men, which were statistically significant. Glucose plasma was significantly higher in women compared to men (p=0.01).  Both atherogenic (low-density lipoprotein (LDL)) and protective (high-density lipoprotein (HDL)) cholesterol were higher in women than men. Women were more likely to take antiplatelet (i.e. Aspirin) and antihypertensive therapies (i.e. beta-Blocker, angiotensin receptor blockers (ARBs), and angiotensin converting enzyme (ACE) inhibitors) than men. Also, it was shown that, Men were more likely to have two-vessel disease (p=0.041) and three-vessel disease (P=0.013) compared to women. Disease in the right coronary artery (RCA) (28.9% vs. 14.4%), circumflex (LCx) (26.0% vs. 15.3%), and left anterior descending (LAD) (37.8% vs. 26.4%) was more plausible to occur in men compared to women (p≤0.05). Conclusion: Access and use of health care programs are needed to control CAD risk factors. The findings of the current study showed the significance of gender in the extent of coronary artery blockages.
