BackgroundThere have been limited data on sex-specific risk factors for coronary artery disease (CAD) in patients with stable chest pain. This study was performed to investigate whether risk factors for CAD differ by sex in stable symptomatic patients.MethodsData were obtained from a nation-wide registry, enrolling 1025 patients (age, 62.0 ± 11.0 years, 587 women) with chest pain who underwent elective invasive coronary angiography under the suspicion of CAD.ResultsA total of 373 patients (36.4%) had obstructive CAD (≥50% stenosis) (men vs. women: 33.8% vs. 38.3%, p = 0.135). In men, univariate analyses showed that age, renal function, total cholesterol, low-density lipoprotein cholesterol, triglyceride, C-reactive protein (CRP), left ventricular (LV) systolic function, and septal annular velocity of LV (e') were significantly associated with the presence of obstructive CAD. Among these factors, a high CRP level (≥0.50 mg/dL) was an independent predictor of CAD in multivariable analysis (odds ratio [OR], 2.93; 95% confidence interval [CI], 1.26-6.82; p = 0.012). In women, univariate analyses showed that age, waist circumference, heart rate, hypertension, diabetes mellitus, low high-density lipoprotein cholesterol, LV systolic function, LV mass index, e' velocity, E/e', and left atrial size were significantly associated with the presence of obstructive CAD. Among these factors, lower e' velocity (<6.35 cm/s) was an independent predictor of CAD in multivariable analysis (OR, 2.38; 95% CI, 1.21-4.70; p = 0.012).ConclusionsAmong patients with stable chest pain, inflammation and LV diastolic dysfunction are independently associated with obstructive CAD in men and women, respectively.
