Introduction
The study aimed to evaluate the prevalence and predictors of left ventricular (LV) reverse remodeling and its impact on long-term prognosis in patients with anterior ST-segment elevation myocardial infarction (STEMI).

Aim
To assess the percentage of reverse remodeling and its prognostic factors in anterior STEMI patients.

Material and methods
This observational study included 40 patients with first ever STEMI of the anterior wall. LV reverse remodeling was defined as the reduction of left ventricular end-systolic volume (LVESV) by ≥ 10% in 3D transthoracic echocardiography (3D-TTE) at 3-month follow-up. 3D-TTE and speckle tracking imaging were performed during index hospitalization, while 3D-TTE and cardiac magnetic resonance (CMR) were performed at 3 months following the procedure. Patients were followed up for a median time of 3.4 years in order to evaluate major adverse cardiovascular events.

Results
Left ventricular reverse remodeling at 3-month follow-up was confirmed in 15 (37.5%) patients. The presence of reverse remodeling was predicted by lower troponin levels (unit OR = 0.86, p = 0.02), lower sum of ST-segment elevations before (unit OR = 0.87, p = 0.03) and after PCI (unit OR = 0.40, p = 0.03), lower maximal ST-segment elevation after PCI (unit OR = 0.01, p = 0.03), lower wall motion score index (unit OR 0.40, p = 0.03) and more negative anterior wall global longitudinal strain (unit OR = 0.88, p = 0.045). Nine MACE were reported in the without reverse remodeling group only. Non-significantly better event-free survival in the reverse remodeling group was demonstrated (log-rank p = 0.07).

Conclusions
Development of reverse modeling in patients with optimal revascularization and tailored pharmacotherapy is relatively high. Further studies are warranted in order to adjudicate its prognostic role for the prediction of adverse events.
