Abstract
- Reperfusion early during myocardial infarction improves ejection fraction and this improvement may represent myocardial salvage in the injured segment. Alternatively, reperfusion of injured myocardium may cause intramyocardial hemorrhage with resultant increased stiffness causing a dyskinetic segment to become akinetic, thus improving ejection fraction without concomitant myocardial salvage. To evaluate this possibility, diastolic stiffness was assessed in a closed chest, anesthetized, normothermic dog model immediately after a 1 or 3 h occlusion of the left anterior descending coronary artery and during the 4 weeks after occlusion.
