BACKGROUND: The significance of cardiac troponin I (TnI) levels in @entity1 with acute @entity385 remains unclear. METHODS: Data were prospectively collected on 1718 @entity1 with acute @entity385 (2009-2010). @entity1 with positive TnI (peak TnI >= 0.1  g/L) were assigned to the @entity583 ( @entity583 ) group if they met diagnostic criteria. The remaining @entity1 with positive TnI were assigned to the no- @entity583 group. @entity1 were followed up for 1.4    1.1 years. Primary outcome was inhospital and long-term all-cause mortality. RESULTS: Positive TnI was present in 309 @entity1 (18%), 119 of whom (39%) were classified as having @entity583 . Positive TnI was independently associated with older age, @entity101 , smoking, peripheral @entity455 , @entity712 , higher systolic blood pressure, higher serum @entity1011 , and lower heart rate (P < .01). @entity1 with @entity583 had the highest inpatient mortality (P < .001) and the lowest survival rate by Kaplan-Meier analysis (P < .0001). Peak TnI greater than or equal to 0.5  g/L, particularly if satisfying criteria for @entity583 , was independently associated with long-term mortality (P < .0001); peak TnI less than 0.5  g/L alone was not when adjusted for covariates. CONCLUSION: Positive TnI greater than or equal to 0.5  g/L in @entity1 with acute @entity385 was independently associated with worse outcomes. @entity1 with diagnosis of @entity583 represent a particularly high-risk subgroup.
