Acupuncture improved cardiac function and reduced fibrosis. A Representative echocardiograms from parasternal long axis images in the Sham, MI and MI + PC6 groups. A summary of echocardiographic parameters is listed below (B–E). B Ejection fraction (EF), C fractional shortening (FS), D left ventricular anterior wall in diastole (LVAWd), E left ventricular posterior wall in diastole (LVPWd), F the serum cTnT level in the Sham, MI and MI + PC6 groups G the serum BNP level in the Sham, MI and MI + PC6 groups. H Tissue sections and fibrosis in the ventricle determined by calculating collagen deposition after Masson's trichrome staining in the Sham (left), MI (middle) and MI + PC6 (right) group mice.
