Abstract

Patients with psoriatic arthritis (PsA) are at increased risk of cardiovascular disease (CVD). High-sensitivity cardiac troponin T (hs-cTnT) is a novel biomarker of CVD. The objective of this study is to determine the prevalence of circulating hs-cTnT in patients with PsA compared to the general population and to characterize a PsA subset with detectable hs-cTnT. A cross-sectional analysis of serum hs-cTnT levels was performed in 116 consecutive patients with PsA and the Tel-Aviv Medical Center Inflammatory Survey cohort of the general population (n = 6052) as a control group. The level and prevalence of hs-cTnT (ng/L) were similar in the entire study population: 4.94 ± 4.4, 30.2% in PsA, 5.17 ± 6.7, 34.2% and 5.38 ± 4.3, 37.9% in unmatched and matched control groups according to age, gender and cardiovascular risk factors, respectively. Factors associated with detectable hs-cTnT in PsA included male gender (p = 0.002), age (p = 0.007), hypertension (p < 0.001), diabetes mellitus (p < 0.001), and smoking (p = 0.001). Axial disease, present in 25% of patients with PsA, was significantly associated with detectable hs-cTnT (p = 0.004). This association remained significant after adjusting for age, gender and traditional cardiovascular risk factors. No correlation between hs-cTnT levels and disease characteristics, PsA activity indices, C-reactive protein levels, or treatments for PsA was found. In summary, serum hs-cTnT was detectable in about the third of the PsA and control cohorts. In PsA, axial disease was significantly associated with detectable hs-TnT, warranting a particular attention to cardiovascular risk assessment in this sub-group. The role of hs-cTnT as a biomarker for CVD in PsA should be further investigated in prospective studies.
