QTc at discharge should not guide post-MI risk stratification; leaves open whether medication-adjusted or serial QTc adds value in contemporary cohorts.

Does QTc interval at discharge predict long-term prognosis in survivors of acute myocardial infarction?
Routine measurement of QTc interval at discharge after an acute myocardial infarction does not offer long-term prognostic value, largely due to confounding effects of medications like digitalis.
Ahnve et al. (1980) conducted a cohort in Acute Myocardial Infarction (n=463). QTc interval measurement at discharge was evaluated on Long-term prognosis. Measurements of QTc interval at discharge had no long-term predictive value for prognosis in survivors of acute myocardial infarction.
