OBJECTIVES

We sought to evaluate regional morphology and function in patients in their first week after having a reperfused anterior myocardial infarction (MI) using magnetic resonance (MR) myocardial tagging.

BACKGROUND

The mechanism of myocardial dysfunction in the remote, noninfarct-related regions is an unresolved issue to date.

METHODS

Sixteen patients with a first reperfused transmural anterior MI were studied with MR tagging at 5 ± 2 days after the event, and the results were compared with those of an age-matched control group regions. The left ventricle (LV) was divided into infarct, adjacent and remote regions. Magnetic resonance tagging provided information on the regional ventricular morphology and function.

RESULTS

Morphologically, an increase of the circumferential radius of curvature was found in the remote myocardium, whereas the longitudinal radius of curvature was increased in all …
