To examine the cardiovascular risk factors in patients with psoriasis and the association between psoriasis and coronary artery, cerebrovascular, and peripheral vascular diseases.
Large Department of Veterans Affairs hospital.
The study included 3236 patients with psoriasis and 2500 patients without psoriasis (controls).
Main Outcome Measures
Using International Classification of Diseases, Ninth Revision, Clinical Modification, codes, we compared the prevalence of traditional cardiovascular risk factors and other vascular diseases as well as mortality between patients with psoriasis and controls.
Similar to previous studies, we found a higher prevalence of diabetes mellitus, hypertension, dyslipidemia, and smoking in patients with psoriasis. After controlling for these variables, we found a higher prevalence not only of ischemic heart disease (odds ratio [OR], 1.78; 95% confidence interval [CI], 1.51-2.11) but also of cerebrovascular (OR, 1.70; 95% CI, 1.33-2.17) and peripheral vascular (OR, 1.98; 95% CI, 1.32-2.82) diseases in patients with psoriasis compared with controls. Psoriasis was also found to be an independent risk factor for mortality (OR, 1.86; 95% CI, 1.56-2.21).
Psoriasis is associated with atherosclerosis. This association applies to coronary artery, cerebrovascular, and peripheral vascular diseases and results in increased mortality.
