Post-hoc analysis
myocardial ischemia
MYOCARDIAL ISCHEMIA
This analysis was performed because of the significant baseline difference in the extent of myocardial ischemia seen in the stress myocardial perfusion imaging. However, adjusting the baseline myocardial ischemia in an ANCOVA analysis was not effective because of this small sample size. So, we compared the patients with the extent of myocardial ischemia less than 30% of the left ventricle, and we found that myocardial ischemia improved depending on the extent of baseline myocardial ischemia only in the LIPUS group (P<0.01) but not in the placebo group (
