JCMR 2020; 22:3. Hyper-acute cardiovascular magnetic resonance T1 mapping predicts infarct characteristics in patients with ST elevation myocardial infarction (CME)

Purpose/ Objective

The recovery of injured myocardium following acute myocardial infarction is unpredictable. Existing approaches rely on recognition of adverse outcomes after the acute phase of myocardial infarction, when myocardial injury is irreversible. Therefore, early recognition of a high-risk subgroup may enable patient selection for specific therapies to improve early outcomes and reduce future risk.

Following this activity, learns will be able to:

1. Native T1 mapping can provide a quantitative assessment of myocardial tissue composition in the setting of acute myocardial infarction. It can identify patients with larger extent of microvascular obstruction and infarct size at both 24 hours and 6 months follow-up.

2. Understand the lack of association between the native T1 at 24hrs and the standard infarct characteristics at 24hr and 6 months. This is an important negative finding that the community should be aware of, so that attention can be focused away from native T1 in this scenario
