Prevalence of high-sensitivity cardiac troponin T in real-life cohorts of psoriatic arthritis and general population: a cross-sectional study

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
