Psoriasis (Ps) and psoriatic arthritis (PsA) are, in addition to skin and osteoarticular lesions, accompanied by a variety of comorbidities, primarily cardiovascular diseases (CVDs), which contributes to shorter life expectancy by on an average of 5-7 years. There are scarce data on the prevalence and pattern of CVDs in a Russian cohort of patients with severe forms of Ps and PsA. Obtaining such information can contribute to the elaboration of programs for screening and prevention of CVDs in this patient group. Objective: to study the prevalence and pattern of CVDs in a hospital cohort of patients with severe forms of Ps and PsA. Subjects and methods. Medical records were retrospectively analyzed in 890 patients with severe forms of Ps (mean age, 51.9±11.6 years; mean Ps duration, 11.6±0.6 years); who had been treated at the Branch of the V.G. Korolenko Clinic, Moscow Research and Practical Center of Dermatovenereology and Cosmetology, in 2010 to 2015. The Psoriasis Area and Severity Index (PASI) averaged 49.4±0.5. The frequency of PsA was assessed by the code L40.5; that of SVDs was determined by the registered diagnoses in accordance with the codes of the International Classification of Diseases, 10th edition (ICD-10): hypertension (ICD-10 code I10-I15), coronary heart disease (CHD) (I20-I25), atherosclerosis (I70), and cerebrovascular disorders (I65-I66). Results and discussion. PsA was identified in 303 (34%) patients. There were a total of 516 (59%) patients with CVDs. Hypertension, CHD, atherosclerosis, and cerebrovascular disorders were more frequently recorded in patients with PsA than in those with PsA without arthritis. Conclusion. CVDs are recorded in more than half of the hospital cohort patients with severe forms of Ps. CVDs are more frequently recorded in PsA than in Ps without arthritis. Hypertension among the SVDs is a leader in its frequency in both groups; more than half of the patients were found to have CHD and atherosclerosis; cerebrovascular disorders were less common.
