AIMS: The purpose of the present study was to assess the evolution of left ventricular (LV) function after acute myocardial infarction (AMI) using global longitudinal peak systolic strain (GLPSS) during 1 year follow-up. In addition, patients were divided in groups with early, late, or no improvement of LV function and predictors of recovery of LV function were established. METHODS AND RESULTS: A total of 341 patients with AMI were evaluated. Two-dimensional echocardiography was performed at baseline, 3, 6, and 12 months. At baseline, LV function was assessed with traditional parameters and GLPSS. Global longitudinal peak systolic strain was re-assessed at 3, 6, and 12 months. Improvement of LV function was based on GLPSS and was observed in 72% of the patients. No differences were observed between patients with early and late improvement. The left anterior descending coronary artery as culprit vessel, peak cardiac troponin T level, diastolic function, and baseline GLPSS were identified as independent predictors of recovery of LV function. CONCLUSION: Improvement of LV systolic function occurred in the majority of patients during follow-up. Global longitudinal peak systolic strain, left anterior descending coronary artery as culprit vessel, peak cardiac troponin T level, and diastolic function were independent predictors of recovery of LV function. Quantification of GLPSS may be of important value for the prediction of recovery of LV function in patients after AMI.
