Psoriasis is associated with a greater risk for cardiovascular procedure and surgery in patients with hypertension: A nationwide cohort study.

Psoriasis increases the incidence of hypertension and cardiovascular disease. However, its effect on the course of cardiovascular disease remains unknown. To investigate whether patients with psoriasis and hypertension have a higher requirement for cardiovascular procedure and surgery than patients with hypertension but without psoriasis, we used the Taiwan National Health Insurance Research Database to identify patients with new-onset hypertension during 2005-2006. Among these patients, those with psoriasis (n = 4039) were matched in a 1:1 ratio by age and sex with patients without psoriasis. The association between psoriasis and cardiovascular interventions was examined using time-varying Cox proportional hazards models. The mean follow-up period was 5.62 years. Psoriasis was associated with an increased risk for cardiovascular procedure and surgery in patients with hypertension (adjusted hazard ratio [aHR], 1.28; 95% confidence interval [CI], 1.07-1.53). When no psoriasis served as a reference group, the aHRs were higher for women than for men, and for patients aged 50-64 years than for younger and older patients. Patients with severe psoriasis or psoriatic arthritis tended to have higher risks of cardiovascular procedure and surgery than patients with mild psoriasis (aHR, 1.22; 95% CI, 0.98-1.51) or patients without psoriatic arthritis (aHR, 1.15; 95% CI, 0.84-1.58), respectively, did, although not reaching statistical significance. In conclusion, patients with hypertension and psoriasis had a greater requirement for cardiovascular interventions than hypertensive patients without psoriasis. More intense assessments for cardiovascular interventions may be necessary in patients with concurrent hypertension and psoriasis than general hypertension patients.
