Can mild hypokinesis of the left ventricle be reversed? i began a hiit, weight toning program along with the excellent diet i already have, with the hope of improving my wall motion. is it possible?

If the hypokinesis was observed during a regular echocardiogram and not during a stress echocardiogram then it is likely irreversible. In contrast, if the hypokinesis is only observed during exercise but not in resting phase then that area may be reversed with medical therapy and exercise which can improve collateral circulation although the vascular lesion is not fixed by stent or bypass surgery.
