So far, systematic reviews have suggested an increased risk of cardiovascular diseases (CVD) in psoriatic patients, though some results have been conflicting. The aim of this study was to update the current level of evidence through a systematic search in MEDLINE, EMBASE and Cochrane Central Register databases. In total, 13 high-quality observational studies estimating the incidence of CVD were included. Patients with mild psoriasis had an increased risk of stroke [Hazard ratio (HR) = 1.10, 95% CI: 1.0-1.19] and myocardial infarction (MI) (HR = 1.20, 95% CI: 1.06-1.35), but not cardiovascular death. The risks of both stroke (HR = 1.38, 95% CI: 1.20-1.60), MI (HR = 1.70, 95% CI: 1.18-2.43) and cardiovascular death (HR = 1.37, 95% CI: 1.13-1.67) were increased in patients with severe psoriasis. In conclusion, this updated meta-analysis confirmed that patients with psoriasis have an increased risk of CVD, especially those with severe psoriasis.
