Context: Four-dimensional speckle-tracking echocardiography (4D-STE) is ideal to accurately assess myocardial deformation. The novel 4D global area strain (GAS) uses global longitudinal and global circumferential strains (GCSs) to detect subtle changes in myocardium. Aims: The aim of this study was to determine the predictive value of 4D strain echocardiography for major adverse cardiovascular events (MACEs) in ST-elevation acute myocardial infarction (STEMI) patients after successful reperfusion by primary percutaneous coronary intervention (PCI). Settings and Design: This was a longitudinal study at a single center. Patients and Methods: We enrolled 170 patients who underwent successful primary PCI. Each patient was evaluated with 2D echocardiography and 4D echocardiography with 4D strain parameters and followed up over a year for the occurrence of MACE. Statistical Analysis Used: Chi-square test, independent t-tests, and multivariate logistic regression analysis were used. Results: Over 1 year of follow-up, 32 MACE were recorded. Patients with MACE were more likely to have had percutaneous transluminal coronary angioplasty done during the index primary PCI intervention, multivessel coronary artery disease, higher left ventricular end-diastolic and end-systolic dimensions (left ventricle end diastolic dimension (LVEDD) andleft ventricle end systolic dimension (LVESD), respectively), lower 2D left ventricular ejection fraction (LVEF), higher wall motion score index, higher baseline heart rate, higher end-diastolic and end-systolic volumes, lower 3D-LVEF, higher 4D global longitudinal strain, 4D-GCS, 4D-GAS, and lower 4D global radial strain (4D-GRS) (P < 0.005 for all parameters). The most powerful predictor for MACE among our study population is 4D-GAS, with the best cutoff value of 4D-GAS >−17 (P = 0.008; odds ratio = 20.668; confidence interval = 2.227–191.827). Conclusions: The novel 4D-GAS echocardiography predicts adverse clinical events in STEMI patients managed by successful primary PCI.
