In Reply We agree that following an acute MI, infarct healing and wall thinning may
not be completed for weeks to months. In our population, patients with an acute MI within 2 weeks of
potential enrollment were excluded, and 71% of enrolled patients had a history of prior MI.
We do not have data concerning the time between the diagnosis of MI and the performance of
delayed-enhancement CMR imaging. However, if our population had included a sizable fraction of
patients with relatively recent MI, the reported prevalence of 19% with regional wall thinning may
represent an underestimate compared with a population in which all patients with an MI within the
last 6 months were excluded.
