Recurrent myocardial infarction identified by centralized troponin review: Insights from the MINT trial

Am Heart JPublished

  • Analysis of patients from the Myocardial Ischemia and Transfusion (MINT) trial
  • randomized to a liberal vs restrictive red blood cell transfusion strategy
  • centralized review of troponin levels collected for 3 days following randomization

Authors' conclusion

In patients with acute MI and anemia, centralized troponin review identified more than half of all recurrent MI events. Patients with centrally identified MI had a higher risk of cardiac death than those with no recurrent MI.

Study context

Population
Patients with acute myocardial infarction (MI) and anemiapatients in the MINT trial
Participants
3,504 patients
Comparison
Differences in cardiac, noncardiac, and all-cause death at 30 and 180 days were compared across patients with any site-reported MI, only centrally identified MI, and no recurrent MI.
  • site-reported MIn = 119
  • only centrally identified MIn = 156

Primary result

As reported in the abstract

Recurrent MI · within 30 days

Recurrent MI, of 3,504 patients

275 (7.8%)

By site-report, of the 275 recurrent MIs

119 (43.3%)

By central troponin review only, of the 275 recurrent MIs

156 (56.7%)

Further findings

OutcomeRR (95% CI)
Cardiac death · 30 days and 180 days — only centrally identified MI vs no recurrent MI · 30 days1.9 (1.0–3.4)
Cardiac death · 30 days and 180 days — only centrally identified MI vs no recurrent MI · 180 days1.7 (1.1–2.7)

Cardiac, all-cause and noncardiac death · 30 and 180 days

Rates of cardiac and all-cause death highest for site-reported MI, intermediate for centrally identified MI, and lowest for no recurrent MI
Rates of noncardiac death did not vary
