Figure 2: Brief Myocardial Ischemia Produces Transient LV Dysfunction Consistent With Stunned Myocardium

A 10-min total left anterior descending coronary artery (LAD) occlusion caused a transient reduction in anterior wall thickening that persisted 1 h after reperfusion, indicative of myocardial stunning. However, regional function continued to improve and returned to normal 3 h after reperfusion. *p < 0.05 versus baseline. n = 5 at 120 min, 180 min, and 24 h; n = 10 at all other time points. LV = left ventricular.
