Key result
A single cTnT measurement on the third morning after STEMI strongly correlated with infarct size (r = 0.84, p < 0.0001) and inversely with LVEF (r = -0.63, p < 0.0001) at 3 months.
Why the study?
Does a single measurement of cardiac troponin T the third morning after onset of STEMI predict infarct size and left ventricular ejection fraction at 3 months in patients treated with thrombolysis?
Population
103 patients with their first ST-segment elevation myocardial infarction (STEMI) treated with thrombolysis
Design
Cohort
Follow-up
3 months

May support day-3 cTnT for post-STEMI prognostication; hypothesis-generating and requires prospective validation before practice change.

A single cTnT measurement on the third day after a first STEMI strongly predicts final infarct size and left ventricular ejection fraction at 3 months.
Bøhmer et al. (2009) conducted a cohort in ST-segment elevation myocardial infarction (STEMI) (n=103). Single measurement of cardiac troponin T (cTnT) was evaluated on Infarct size and left ventricular ejection fraction (LVEF) at 3 months (r = 0.84, p=< 0.0001). A single cTnT measurement on the third morning after STEMI strongly correlated with infarct size (r = 0.84, p < 0.0001) and inversely with LVEF (r = -0.63, p < 0.0001) at 3 months.
