Figure 1 Example of Strain Curves in Infarcted and Remote Areas

Myocardial strain assessed in the acute phase compared with the myocardial scarring 9 months later (middle panel). At left, dyskinesia is shown in the infarcted area with systolic lengthening of the myocardium, followed by postsystolic shortening. A normal strain curve from the noninfarcted remote area with systolic shortening and diastolic lengthening is shown at right. Arrows indicate the peak negative strain values. MRI = magnetic resonance imaging.
