Psoriasis and Coronary Artery Disease in Hispanics

Psoriasis is an immune disorder characterized by chronic activation of systemic inflammation. Morbidity and mortality in patients with psoriasis is attributed mainly to cardiovascular disease. There are studies in Caucasians and African- Americans, but little is known about how psoriasis is associated to coronary artery disease (CAD) in Hispanics. We intend to describe the angiographic findings of a group of Puerto Rican patients with psoriasis. Retrospective cohort study of 46 patients with psoriasis were studied. Coronary angiographic reports were reviewed, and collected data was statistically analized. Population median age was 56, and 72% were males. Of the 46 patients, 27 had CAD by angiographic criteria (58.7%). Twelve patients were referred to bypass graft surgery, 8 underwent coronary stent placement, and 7 were treated medically. Whether psoriasis can be considered a risk factor for developing CAD is still on debate. More than 50% of our patients with psoriasis had angiographic evidence of CAD. Adjusting for traditional cardiovascular risk factors, we found no significant association (p>0.05) with CAD. We believe that inflammation plays a contributing role in the increased risk of CAD in these patients. The importance of this study relies on being the first retrospective analysis in a group of Hispanics trying to determine an association between coronary artery disease and psoriasis when in Puerto Rico, coronary artery disease is 30% less than in the United States.
