BACKGROUND: Psoriasis is a chronic inflammatory skin disorder affecting about 2% of white-skinned individuals. Epidemiological data on the prevalence and degree of coronary artery calcification (CAC) as an indicator for cardiovascular diseases in patients with psoriasis are contradictory. OBJECTIVES: To study the prevalence and degree of CAC as an indicator for cardiovascular diseases in 32 patients with psoriasis matched for age, sex and risk factors to an equally sized control population. METHODS: Noncontrast-enhanced 16-row spiral computed tomography was performed in patients and controls. RESULTS: We found a significantly increased prevalence (59.4% vs. 28.1%, P = 0.015) and severity (CAC score according to Agatston 3.7 vs. 0.0, P = 0.019) of CAC in patients with psoriasis. Multiple linear regression calculations identified psoriasis as a likely independent risk factor for CAC. CONCLUSIONS: Our results point towards the potentially systemic nature of the inflammatory processes underlying the pathogenesis of psoriasis, which may therefore be considered a potentially severe systemic disease.

Ludwig et al. (2006) conducted a case-control in Psoriasis and coronary artery calcification (n=64). Psoriasis vs. Matched control population without psoriasis was evaluated on Prevalence of coronary artery calcification (CAC) (p=0.015). Psoriasis was associated with a higher prevalence (59.4% vs 28.1%, P=0.015) and severity (Agatston score 3.7 vs 0.0, P=0.019) of coronary artery calcification compared to matched controls.
