Abstract
BACKGROUND
Prognostic value of high-sensitivity cardiac troponin T (hs-cTnT) assays have been assessed in selected populations in different studies and in registries of members of the general population with low cardiovascular risk. The aim of this study was to determine the prognostic value of hs-cTnT in an asymptomatic very-high cardiovascular risk Spanish population.
METHODS
From a previous prospective cohort of the TUSARC (troponina T UltraSensible en pacientes Asintomáticos de alto Riesgo Cardiovascular) registry, follow-up was conducted in 602 patients (93.18%). The association of high hs-cTnT (≥99th percentile value) and incidence of primary event was studied. A primary event was defined as a combined major cardiovascular event (incidence of cardiovascular death, decompensated heart failure, non-fatal cerebrovascular event, non-fatal myocardial infarction, or coronary revascularization). The association between high hs-cTnT and incidence of secondary events was studied as well.
RESULTS
In patients with high hs-cTnT, the incidence of primary event during follow-up was significantly higher (18.30% vs 3.67% P < .001): heart failure (6.25% vs 0.73% P < .001), cardiovascular death (7.29% vs 0.00% P < .001), and death from any cause (7.81% vs 0.98% P < .001).
CONCLUSIONS
In an asymptomatic very-high cardiovascular risk Spanish population, elevated hs-cTnT was significantly associated with incident major cardiovascular combined end point and incidence of heart failure, cardiovascular death, and death from any cause.
