PSORIASIS and co-morbidity no. 1 co-morbidity: PSA! evidence for increased risk for cardiovascular mortality –NEJM 1973, 288: 912 –BJD 1978, 99: 469 –JID 2001, 117: 1531 –Eur J Epidemiol 2004, 19: 225 but: –more smokers BJD 1996, 135: 859 –more diabetes ADR 1975, 254: 43 –more hypertension Dermatologica 1986, 172: 298 so: What is the role of PSO? –background: chronic inflammation causes atherosclerosis

PSORIASIS AND CAC Is there a correlation between disease severity and P-selectin expression? –monitoring of in- patients PASI FACS

PSORIASIS AND CAC Are PSO patients at risk to develop cardiac disease? –32 PSO patients –matched controls –spiral CT CAC score (Agatston)
