Cardiovascular comorbidities among patients with psoriasis: a national register-based study in China.

This study aims to illustrate epidemiology of comorbid CVD in the real-world clinical setting of patients with psoriasis in China. We used data of adult patients with psoriasis who were registered in the register of China National Clinical Center for Skin and Immune Diseases between August 2020 and September 2021. Psoriasis was clinically diagnosed following the national guidelines. Univariate and multivariate logistic regression models were used to examine the factors associated with comorbid CVD in patients with psoriasis. Of the 11,560 psoriasis patients (age ≥ 18 years, mean age 41.87 years, 64.88% males), 236 were ascertained with CVD, with the overall prevalence being 2.62%. Multivariate logistic regression analysis suggested that the odds ratio (95% confidence interval) of CVD in psoriasis patients was 2.27 (2.03-2.54) for older age (per 10-year increment), 0.65 (0.48-0.90) for female, 2.07 (1.39-3.06) for obesity (BMI ≥ 28 vs. < 24 kg/m), 2.55 (1.85-2.52) for smoking, 7.63 (5.86-9.94) for hypertension, 4.27 (3.76-4.85) for diabetes, 1.14 (1.00-1.30) for having a history of drug allergy, 2.27 (1.61-3.20) for having family history of psoriasis, and 1.76 (1.16-2.67) for severe disease (severe vs. mild) with a dose-response relationship (P < 0.001). In patients with psoriasis, comorbid CVD was associated with smoking, obesity, hypertension, diabetes, history of drug allergy, family history of psoriasis, and the psoriasis severity.
