Psoriasis and coronary heart disease-not as severe as predicted.

BACKGROUND

Psoriasis is a systemic disorder involved in several disease processes, including cancer, metabolic syndrome and cardiovascular disease (CVD). Previous studies showed that psoriasis is most likely an independent risk factor for CVD, yet the extent of its impact on CVD and the extent of coronary artery disease (CAD) remains unclear. We investigated the correlation of psoriasis to the severity of CAD in age and gender-matched patients with CAD with and without psoriasis.

METHODS

This is a retrospective, case-control study of 59 patients with psoriasis who underwent coronary angiography were matched using a computer software to 59 patients without psoriasis according to age, gender, smoking status, hyperlipidemia, hypertension and diabetes. CAD severity was defined according to number of affected vessels (single vs. multiple) and location of lesions (proximal vs. distal).

RESULTS

CAD severity was significantly higher in the control group compared to the psoriasis group (P = 0.038). Among patients with psoriasis, 20.3% were disease free or with low severity (42.4%), while only 37.3% had severe CAD. Among patients without psoriasis, the majority had severe CAD (57.6%), followed by low severity (30.5%) or disease free (11.9%). We did not find an association of prior treatment with anti-inflammatory medications and the severity of CAD.

CONCLUSIONS

Our results show that although psoriasis may be a risk factor for CAD, psoriatic patients have a less severe CAD compared to the general population. The use of anti-inflammatory medications does not explain this finding.
