Low levels of high-density lipoprotein cholesterol predict the presence of coronary artery disease in patients with aortic aneurysms.

To identify predictors of the presence of coronary artery disease (CAD) in patients with planned surgery for aortic aneurysms, we reviewed clinical profiles and angiography records of 191 patients with aortic aneurysms (34 thoracic, 137 abdominal, and 20 thoracoabdominal; 162 men; mean age, 75.2 ± 7.7 years). The incidence of CAD was 38.7% among all the patients. Patients with CAD had significantly low levels of high-density lipoprotein cholesterol (HDL-C) as compared with patients without CAD (45 ± 9 vs 51 ± 13 mg/dL; P = .009). Multivariate analysis showed that only low HDL-C levels were associated with the presence of CAD (adjusted odds ratio, 0.946; 95% confidence interval, 0.911-0.983; P = .004). The optimal cutoff level of HDL-C to predict CAD was 47.50 mg/dL. The CAD is common in patients with aortic aneurysms, and low levels of HDL-C are independently associated with the presence of CAD.
