This study investigated the association between obesity type and obstructive coronary artery disease (CAD) in postmenopausal women. Study data were obtained from a nation-wide registry, composed of 659 women older than 55 years with chest pain undergoing elective invasive coronary angiography in the suspicion of CAD. Obstructive CAD was defined as angiographic findings of ≥50% diameter stenosis with any major epicardial coronary artery. Overall obesity was defined as a body mass index of ≥25 kg/m, and central obesity was defined as a waist circumference of ≥85 cm. A total of 311 women (47.2%) had obstructive CAD. The incidence of overall obesity was not different between participants with and without obstructive CAD (P = 0.340), but the prevalence of obstructive CAD was significantly higher in participants with central obesity than those without (55.5% vs 41.0%, P < 0.001). There was no significant difference in body mass index between participants with and without obstructive CAD (P = 0.373). Multivariable analysis showed that central obesity was associated with obstructive CAD even after controlling for potential confounders (odds ratio, 1.61; 95% confidence interval, 1.10-2.34; P = 0.013). However, overall obesity was not associated with obstructive CAD in the same multivariable analysis (P = 0.228). Central obesity but not overall obesity is associated with obstructive CAD in postmenopausal women with stable chest pain undergoing invasive coronary angiography. : Video Summary: Supplemental Digital Content 1, http://links.lww.com/MENO/A440.
