Concentrations of highly sensitive cardiac troponin-I predict poor cardiovascular outcomes and adverse remodeling in chronic heart failure.

Highly sensitive troponin (hsTn) assays may predict cardiovascular (CV) events and left ventricular (LV) remodeling in patients with heart failure (HF). In this study, 99 subjects with LV systolic dysfunction (LVSD) were followed 10 ± 3 months with serial measurement of hsTnI by a novel method. hsTnI was detectable in all subjects and was above the 99th percentile of a normal population in 56.7 %. Supramedian baseline hsTnI concentration was associated with higher-risk clinical features and shorter time-to-first event (p = 0.008). Across serial measurements, more time spent ≤ 10.9 pg/mL was associated with a lower CV event rate after adjustment (odds ratio (OR) = 0.81; p = 0.008); rising hsTnI also predicted progressive LV remodeling. In conclusion, hsTnI detected significant myocardial necrosis in a majority of patients with chronic HF due to LVSD and when measured serially, provided independent risk information for poor CV outcomes and deleterious LV remodeling.
