Conclusions
In this study, we investigated the hypothesis that cardiovascular
rehabilitation after an uncomplicated AMI, through a supervised program
of 16 weeks of physical exercise, would have a positive impact on the LV
contraction mechanics. Despite the known benefits of exercise in the
overall health of practicing individuals, there was no significant
improvement in the LV longitudinal, radial and circumferential
deformation parameters. However, exercise had a significant impact on
the LV torsional mechanics, particularly composed of reduced basal
rotation, twist velocity, torsion and torsional velocity. This outcome
can be interpreted as a ”LV torsional reserve” in individuals who
exercised in post-AMI, possibly a physiologically more efficient
torsional mechanics emerging from routine physical exercise.
