Patients with psoriasis may have an increased risk of cardiovascular disease and myocardial infarction. The aim of this study was to investigate whether psoriasis is associated with an increased prevalence of coronary artery disease (CAD) independent of established cardiovascular risk factors in patients undergoing coronary angiography. A retrospective cohort analysis was performed by linking records of all patients undergoing coronary angiography from 2004 through 2009 with dermatology medical records. From an overall cohort of 9,473 patients, we identified 204 patients (2.2%) with psoriasis before coronary angiography. Patients with psoriasis had higher body mass index (31.3 ± 8.1 vs 29.3 ± 7.1 kg/m 2, p <0.001) but the prevalence of other risk factors was similar. Median duration of psoriasis before cardiac catheterization was 8 years (interquartile range 2 to 24). Patients with psoriasis were more likely to have CAD (84.3% vs 75.7%, p = 0.005) at coronary angiography. After adjusting for established cardiovascular risk factors, psoriasis was independently associated with presence of angiographically confirmed CAD (adjusted odds ratio 1.8, 95% confidence interval 1.2 to 2.8, p = 0.006). In patients with psoriasis, duration of psoriasis >8 years was also independently associated with angiographically confirmed CAD after adjusting for established cardiovascular risk factors (adjusted odds ratio 3.5, 95% confidence interval 1.3 to 9.6, p = 0.02). In conclusion, patients with psoriasis and especially those with psoriasis for >8 years have a higher prevalence of CAD than patients without psoriasis undergoing coronary angiography.
