Abstract

Background: Focused evaluations on potential sex differences in the angiographic findings of the coronary arteries are scarce. This study was performed to compare the angiographic extent and localization of coronary stenosis between men and women. Methods: A total of 2348 patients (mean age 62.5 years and 60% women) with stable chest pain undergoing invasive coronary angiography (CAG) were recruited from the database of the nation-wide chest pain registry. Obstructive coronary artery disease (CAD) was defined as ≥ 50% stenosis of the left main coronary artery and/or ≥ 70% stenosis of any other epicardial coronary arteries. Results: Although women were older than men (64.4 ± 10.3 vs. 59.5 ± 11.4 years, P < 0.001), men had worse risk profiles including high blood pressure, more frequent smoking and elevated triglyceride and C-reactive protein. The prevalence of obstructive CAD was significantly higher in men than in women (37.0% vs. 28.4%, P < 0.001). Men had a higher prevalence of LM disease (10.3% vs. 3.5%, P < 0.001) and three-vessel disease (16.1% vs. 9.5%, P = 0.007) compared to women. In multiple binary logistic regression analysis, the risk of men having LM disease or three-vessel disease was 7.4 (95% confidence interval 3.48–15.97; P < 0.001) and 2.7 (95% confidence interval 1.57–4.64; P < 0.001) times that of women, respectively, even after controlling for potential confounders. Conclusions: In patients with chest pain undergoing invasive CAG, men had higher obstructive CAD prevalence and more high-risk angiographic findings such as LM disease or three-vessel disease.
