Background: Psoriasis patients have a high prevalence of cardiovascular events and are thought to have a relative risk increase of 25% as compared to the general population. However, a causal relationship between psoriasis and cardiovascular disease has not been established. We sought to perform a systematic review of existing data regarding the presence of endothelial dysfunction and subclinical atherosclerosis in patients with plaque psoriasis.
Methods: A systematic literature search was performed, using Medline database and Ovid SP for relevant literature up to November 2012. Twelve studies met inclusion criteria from an initial search result of 529 articles.
Results: Among the twelve studies meeting inclusion criteria, two (17%) reported increased mean coronary artery calcification (CAC) in psoriatic patients. Six studies (50%) showed carotid intima-media thickness [CIMT] increase in psoriasis. Five studies (42%) examined flow mediated dilation [FMD], of which three showed decreased FMD in psoriasis patients. One study (8%) each demonstrated a decreased coronary flow reserve and increased arterial stiffness as assessed by pulse wave velocity.
Conclusions: Patients with psoriasis have an increased burden of subclinical atherosclerosis and endothelial dysfunction. Patients with greater severity and/or disease duration should be targeted for primary screening for cardiovascular disease risk reduction.
