Abstract
BACKGROUND: Identifying low-risk acute heart failure patients safe for discharge from the emergency department is a major unmet need. METHODS AND RESULTS: A prospective, observational, multicenter pilot study targeting lower risk acute heart failure patients to determine whether hsTnT (high-sensitivity troponin T) identifies emergency department acute heart failure patients at low risk for rehospitalization and mortality. hsTnT was drawn at baseline and 3 hours. Phone follow-up occurred at 30 and 90 days. The primary end point composite of all-cause mortality, rehospitalization, and emergency department visits at 90 days (changed from 30 days because of lack of mortality events), analyzed using logistic regression. Secondary end points: 30- and 90-day all-cause mortality. hsTnT values less than the 99th percentile were defined as low hsTnT. Out of 527 enrolled patients, 499 comprised the initial analysis set. Of these, 332 had both 0- and 3-hour hsTnT drawn, of whom 319 completed 30 day follow-up. The average age was 62, 60% male, and 57% black. Median hsTnT was 26.4 ng/L (interquartile range, 15.1-44.3). There were 99 (21%) 30-day composite events, 13 (2.7%) deaths at 30 days, and 25 deaths (8.2%) at 90 days. Serial hsTnT values below the 99th percentile were not associated with a lower risk for the 90-day primary composite end point (odds ratio, 0.79; 95% CI, 0.42-1.50; P=0.4736). However, no deaths occurred in the low hsTnT group at 30 days with 1 death at 90 days. CONCLUSIONS: hsTnT did not identify patients at low risk for the primary outcome of rehospitalization, emergency department visits, and mortality at 90 days.
