During 3.1 ± 0.7 years of follow-up, 137 patients (28%) had ≥1 VA. cTnT concentrations were associated with an increased VA risk (per log-unit, HR: 1.63; 95% CI: 1.31-2.01; <em>P</em> &lt; 0.001), also after adjustment for age, sex, body mass index, coronary artery disease, HF, renal function, and left ventricular ejection fraction (P &lt; 0.001).
