Different modes of exercise have been reported to affect post-MI recovery differently: Intermittent aerobic exercise (IAE) is effective in diminishing pathological myocardial transformation in the post-infarction failing rat heart22, increasing peak oxygen uptake23 and improving functional capacity and life quality in patients with chronic heart failure (CHF)24, whereas mechanical vibration training (MVT) accelerates the reperfusion of vessels25 and elevates circulating levels of angiogenic regulators such as VEGF and MMP-2/9 in humans26. Here, MMP2 is linked to congestive heart failure.
