| Research Abstract |
Objectives: We hypothesized that treatment with whole body periodic acceleration (WBPA) reverses left ventricular (LV) remodeling as a result of increased peripheral vasodilatory reserve in patients with old myocardial infarction (OMI). Methods: Thirteen OMI patients years who received full medication were randomly assigned to undergo 20 sessions of mild WBPA (Control group) or regular WBPA with the motion platform for 4 weeks (WBPA group). Mild WBPA was applied at 2 to 3 Hz and approximately +-0.3 m/sec2 for 45 min and regular WBPA was applied at approximately +-2.2 m/sec2. We repeated the blood sampling and treadmill exercise test. Results: Plasma BNP levels significantly decreased in the regular WBPA group. In the regular WBPA group, the exercise time until dyspnea onset significantly increased, and the double product at 0.1 mV ST depression. Conclusions: Treatment with regular WBPA for OMI patients ameliorates exercise capacity through central and peripheral effects.
