Abstract

Aims: To assess the value of three-dimensional echocardiography (3DE) parameters of LV volumes and systolic dyssynchrony index (SDI) for the prediction of LV remodeling after acute myocardial infarction (AMI) and to compare them with two-dimensional echocardiography (2DE) parameters. Methods: 2DE and 3DE were performed in 109 patients with AMI within 3 days from the onset of MI and 12 months after percutaneous coronary intervention (PCI). LV remodeling was defined as a ≥15% increase in the LV end-diastolic volume at follow-up. SDI was calculated as a standard deviation of the time from cardiac cycle onset to minimum systolic volume in 17 LV segments.  Results: LV remodeling was identified in 52 (49,1%) patients using 2DE and 46 (42,2%) patients using the 3DE method. Evaluated 3DE parameters, such as EDV [area under the receiver operating characteristic (ROC) curve (AUC) 0.78, sensitivity 72,4%, specificity 79,5%], end- systolic volume (AUC 0.73, sensitivity 70,7%, specificity 78,3%), SDI (AUC 0.79, sensitivity 81,6%, specificity 85,9%), had significant prognostic value for LV remodeling. According to the AUC, SDI had the highest predictive value.  Conclusion: 3DE volume parameters, especially 3D SDI, play important roles in the prediction of LV remodeling after AMI and can be used in clinical practice.
