Background: The slight increase in cardiac troponin in the blood of patients with heart failure (HF) suggests that myofibrils are degraded in the myocardium and released in the circulation, reflecting a continuous and progressive injury process in the contractile system.
Objective: To correlate the serum levels of cardiac troponin T (TnT) at the hospital admission of patients with decompensated HF and prognosis.
Methods: A total of 79 consecutive patients, hospitalized due to decompensated HF, with LVEF < 45%, were included in the study.
