【 摘 要 】

Background-Aortic coarctation (CoA) is reported to predispose to coronary artery disease (CAD). However, our clinical observations do not support this premise. Our objectives were to describe the prevalence of CAD among adults with CoA and to determine whether CoA is an independent predictor of CAD or premature CAD. Methods and Results-The study population was derived from the Quebec Congenital Heart Disease Database. We compared patients with CoA and those with a ventricular septal defect, who are not known to be at increased risk of CAD. The prevalence of CAD in patients with CoA compared with those with ventricular septal defect was determined. We then used a nested case-control design to determine whether CoA independently predicted for the development of CAD. Of 756 patients with CoA who were alive in 2005, 37 had a history of CAD compared with 224 of 6481 patients with ventricular septal defect (4.9% versus 3.5%; P = 0.04). Male sex (odds ratio [OR], 2.13; 95% confidence interval [CI], 1.62-2.80), hypertension (OR, 1.95; 95% CI, 1.44-2.64), diabetes mellitus (OR, 1.68; 95% CI, 1.09-2.58), age (OR per 10-year increase, 2.28; 95% CI, 2.09-2.48), and hyperlipidemia (OR, 11.58; 95% CI, 5.75-23.3) all independently predicted for the development of CAD. CoA did not independently predict for the development of CAD (OR, 1.04; 95% CI, 0.68-1.57) or premature CAD (OR for CoA versus ventricular septal defect, 1.44; 95% CI, 0.79-2.64) after adjustment for other factors. Conclusions-Although traditional cardiovascular risk factors independently predicted for the development of CAD, the diagnosis of CoA alone did not. Our findings suggest that cardiovascular outcomes of these patients may be improved with tight risk factor control. (Circulation. 2012; 126: 16-21.)
