Abstract

Objective To compare the presence of cardiovascular (CV) risk factors and established CV disease in patients with psoriatic arthritis (PsA) and the general population and to compare the 10-year risk of a fatal CV event calculated by the Systematic Coronary Risk Evaluation (SCORE) algorithm.

Methods Patients with PsA (n=338) and controls (n=50 468) were recruited from the Nord-Trøndelag Health Study 3. Age-adjusted and sex-adjusted prevalence rates of CV risk factors and comorbidity were calculated and the SCORE algorithm was applied.

Results There was an increased prevalence of angina pectoris (5.0% vs 3.6%, p=0.01), history of percutaneous coronary intervention (2.4% vs 1.4%, p=0.04), hypertension (45.3% vs 39.3%, p=0.01), obesity (32.0% vs 22.4%) and tobacco smoking (21.3% vs 16.4%, p=0.02) in patients with PsA compared with controls. Patients with PsA had elevated levels of C reactive protein (CRP; p<0.001), body mass index (BMI; p<0.001) and triglycerides (p=0.01). The median calculated CV risk in patients with PsA was low and comparable with controls (0.87 vs 0.83, p=0.24). The distribution across CV risk classes was similar among patients with PsA and controls.

Conclusions Patients with PsA have a higher risk of CV disease than the background population, although there was no difference between groups in 10-year risk of a fatal CV event estimated by SCORE. However, patients with PsA had elevated levels of CV risk factors not included in the SCORE algorithm, such as BMI, triglycerides and CRP.
