Abstract
Background: Psoriasis is known to be associated with metabolic syndrome, a well-established risk factor for ischemic heart disease and stroke. Emerging evidence indicates that psoriasis is an independent risk factor for cardiovascular disease and stroke. Objective: To evaluate whether psoriasis is independently associated with myocardial infarction (MI), ischemic heart disease (MI, angina pectoris, or coronary heart disease), and stroke, we conducted a cross-sectional study using the US National Health and Nutrition Examination Survey (NHANES) database. Methods: Data on clinical history of psoriasis, MI, angina pectoris, coronary heart disease, and stroke from the questionnaire as well as laboratory parameters on serum lipid and uric acid levels in the cycle years 2003-2006 and 2009-2012 were analyzed. Multivariate analysis with logistic regression modelling was performed with the aforementioned cardiovascular events or stroke as the dependent variables and with risk factors such as age, gender, ethnic group, current smoking status, alcohol consumption, metabolic syndrome, hyperuricemia, and psoriasis as independent variables. Results: There were 520 cases of psoriasis, and 108 of them had metabolic syndrome (20.8%). Well-established cardiovascular risk factors such as age, gender, ethnic group, smoking, alcohol consumption, metabolic syndrome, and hyperuricemia were also found to have significant associations with MI and ischemic heart disease (all P values <.001). Psoriatic patients were at significantly higher risks of developing MI (odds ratio [OR] 2.24; 95% CI: 1.27-3.95; P = .005) and ischemic heart disease (OR 1.90; 95% CI: 1.18-3.05; P = .008), but not stroke (OR 1.01; 95% CI: 0.48-2.16; P = .744), after adjustment was made for major cardiovascular risk factors. Conclusion: This study provides epidemiological evidence that psoriasis may be independently associated with the development of MI and ischemic heart disease. Physicians should be cognizant of any underlying cardiovascular risk factors, especially among psoriatic patients with metabolic syndrome, and manage them according to national guidelines.
