Combining vascular imaging data with information on traditional cardiovascular risk factors could improve the accuracy of cardiovascular risk stratification in patients with psoriatic disease (PsD), according to a new research published in Arthritis & Rheumatology.
The cohort study included 559 adults with PsD who underwent ultrasound assessment of the carotid arteries at baseline between 2009 and 2015 to assess the burden of atherosclerosis. Information about cardiovascular risk factors was collected and used to calculate the expected cardiovascular risk using the Framingham Risk Score (FRS). Participants were followed until December 31, 2017.
A total of 23 patients experienced confirmed cardiovascular events (CVE). The rate of first CVE during the study period was 1.11 events per 100 patient years (95% CI 0.74-1.67). When analysed separately, total plaque area (TPA) (HR 3.74; 95% CI 1.55-8.85; P=.003), mean carotid intima media thickness (cIMT) (HR 1.21; 95% CI 1.03-1.42; P=.02), max cIMT (HR 1.11; 95% CI 1.01-1.22; P=.03) and high TPA category (HR 3.25; 95% 1.18-8.95; P=.02) predicted incident CVE after controlling for FRS.
"Our study suggests that ultrasound can also be used to identify patients that are at high cardiovascular risk who may be missed by the conventional methods such as the FRS," said senior author Lihi Eder of the University of Toronto.
