- Influence of Physical Training after a Myocardial Infarction on Left Ventricular Contraction Mechanics(2023) LIMA, Marcio Silva Miguel; DALCOQUIO, Talia Falcao; ABDUCH, Maria Cristina Donadio; TSUTSUI, Jeane Mike; MATHIAS, Wilson; NICOLAU, Jose CarlosBackground: Exercise plays a positive role in the course of the ischemic heart disease, enhancing functional capacity and preventing ventricular remodeling.Objective: To investigate the impact of exercise on left ventricular (LV) contraction mechanics after an uncomplicated acute myocardial infarction (AMI).Methods: A total of 53 patients was included, 27 of whom were randomized to a supervised training program (TRAINING group), and 26 to a CONTROL group, who received usual recommendations on physical exercise after AMI. All patients underwent cardiopulmonary stress testing and a speckle tracking echocardiography to measure several parameters of LV contraction mechanics at one month and five months after AMI. A p value < 0.05 was considered statistically significant in the comparisons of the variables.Results: No significant difference was found in the analysis of LV longitudinal, radial and circumferential strain parameters between groups after the training period. After the training program, analysis of torsional mechanics demonstrated a reduction in the LV basal rotation in the TRAINING group in comparison to the CONTROL group (5.9 +/- 2.3 vs. 7.5 +/- 2.9o; p=0.03), and in the basal rotational velocity (53.6 +/- 18.4 vs.68.8 +/- 22.1 degrees/s; p=0.01), twist velocity (127.4 +/- 32.2 vs. 149.9 +/- 35.9 degrees/s; p=0.02) and torsion (2.4 +/- 0.4 vs. 2.8 +/- 0.8 degrees/cm; p=0.02).Conclusions: Physical activity did not cause a significant improvement in LV longitudinal, radial and circumferential deformation parameters. However, the exercise had a significant impact on the LV torsional mechanics, consisting of a reduction in basal rotation, twist velocity, torsion and torsional velocity which can be interpreted as a ventricular ""torsion reserve"" in this population.
