Abstract BACKGROUND: The possible connection between psoriasis with cardiovascular disease and associated risk factors has been implied, but inconsistent results have been reported. OBJECTIVE: We sought to create an overview and statistical summary of the previous literature with elucidating subgroup analysis. METHODS: This was a meta-analysis of observational studies using random effect statistics. A systematic search of observational studies of psoriasis as study variable and cardiovascular disease and associated risk factors as outcome, published before October 25, 2012, was conducted. RESULTS: Of 835 references in the original search, 75 relevant articles were identified. We included 503,686 cases and 29,686,694 controls. Psoriasis was associated with cardiovascular disease in total (odds ratio [OR] 1.4; 95\% confidence interval [CI] 1.2-1.7), ischemic heart disease (OR 1.5; 95\% CI 1.2-1.9), peripheral vascular disease (OR 1.5; 95\% CI 1.2-1.8), atherosclerosis (OR 1.1; 95\% CI 1.1-1.2), diabetes (OR 1.9; 95\% CI 1.5-2.5), hypertension (OR 1.8; 95\% CI 1.6-2.0), dyslipidemia (OR 1.5; 95\% CI 1.4-1.7), obesity by body mass index (OR 1.8; 95\% CI 1.4-2.2), obesity by abdominal fat (OR 1.6; 95\% CI 1.2-2.3), and the metabolic syndrome (OR 1.8; 95\% CI 1.2-2.8), but not associated with cerebrovascular disease (OR 1.1; 95\% CI 0.9-1.3) and cardiovascular mortality (OR 0.9; 95\% CI 0.4-2.2). The strongest associations were seen in hospital-based studies and psoriatic arthritis. Population-based studies did not show significant associations, with the exception of dyslipidemia. LIMITATIONS: The heterogeneity of the studies makes clinical interpretation challenging. CONCLUSIONS: In aggregate, psoriasis was associated with ischemic heart disease and cardiovascular risk factors. The association was only significant for hospital-based studies, except for dyslipidemia, which was also significant in population-based studies.
