Edema size continuously decreased from baseline (32.8 %LV) to 16.4 %LV at 6.5 months, while native T1 time within the edema remained significantly increased (1253 ±103 ms) compared to remote normal myocardium (1018 ± 43 ms) throughout all follow-ups.

Overview

Persistent T1 elevation signals incomplete resolution at 6 months post-AMI; hypothesis-generating for serial CMR monitoring in future cohorts.

Structured PICO

P
Population
11 patients after reperfused acute myocardial infarction (AMI)
I
Intervention
Serial native T1- and T2-mapping cardiac magnetic resonance imaging (CMR) at baseline (10 ±7 days), 7.2 ±1.4 weeks, 3.4 ±0.3 months, and 6.5 ±0.5 months
O
Outcome
Quantitative evaluation of resorption of myocardial edema (edema size and T1/T2 times)surrogate

Serial native T1 and T2 mapping reveals that myocardial edema following reperfused AMI decreases over time but persists for at least 6 months.
