Background Psoriatic arthritis (PsA) is associated with higher prevalence and risk for cardiovascular morbidities [1,2].
Objectives The aim of the study is to substantiate these findings in our population and to examine additional aspects of cardiovascular morbidities, including congestive heart failure and cardiomyopathy.
Methods A retrospective, longitudinal, cohort case control study was performed on records of patients with PsA between 2000 and 2013 from the database of Israel's largest health care provider, Clalit Health Services. For each patient with PsA, 5 control patients without history of psoriasis or rheumatoid arthritis were chosen, matched for age and gender. The following morbidities were analyzed: ischemic heart disease (IHD), valvular heart disease excluding mitral valve prolapse, congestive heart failure (CHF), cardiomyopathy, idiopathic hypertrophic subaortic stenosis (IHSS), cerebrovascular accident (CVA), carotid artery disease, peripheral vascular disease (PVD), and aortic aneurism. T-test was used to compare continuous variables and Chi square test was used for categorical variables. Age, gender, socioeconomic status and ethnicity were entered into a multivariate regression model.
Results The study included 3161 patients with PsA, 1474 males (46.6%) and 1687 (53.4%) females with a mean age of 58.29±15.44 years, and 15,805 controls. Comparative analysis demonstrated higher prevalence of the following in the case cohort: IHD (18.95% vs. 14.49%) p<0.0001, valvular heart disease (6.99% vs. 5.10%) p<0.0001, CHF (5.98% vs. 4.61%) p<0.001, cardiomyopathy (1.28% vs. 0.80%) p<0.010, carotid artery disease (2.53% vs. 1.99%) p=0.053. and peripheral vascular disease (4.87% vs. 3.68%) p=0.001. Prevalence of IHSS, CVA and aortic aneurism were not significantly higher in the patients compared with the control group. The following were significantly more prevalent in patients than controls in multivariate regression analysis model: IHD (P<0.0001), CHF (P<0.0001), cardiomyopathy (p=0.011), and PVD (p=0.001) valvular heart disease (P<0.0001); and there was a trend to higher prevalence of carotid artery disease in PsA patients (p=0.066).
Conclusions A high prevalence of cardiovascular co-morbidities was found in this cohort of PsA patients. The spectrum of cardiac involvement was not limited to IHD, carotid artery disease and PVD, and included also increased risk of CHF, cardiomiopathies and valvular heart disease. A high index of suspicion, and close monitoring and treatment of cardiovascular risk factors are recommended.
