(A) Conscious echocardiography of the left ventricle indentified significant decreases in tumor-induced anterior and posterior wall thickness in diastole, heart weight to body weight ratio (HW/BW), and relative wall thickness, that were not identified when 500 mg/kg/day resveratrol was given. (B) Representative M-mode recordings from images used in the analysis of (A). A one-way ANOVA was performed to determine significance, followed by a Holm-Sidak pairwise comparison to significance between groups. *p<0.05. BW, body weight, HW, heart weight; RWT=LVPW;d/s+LVAntW; d/s / LVEDD or LVEDS; LV mass (index)=[1.055* ( (ExLVD;d)3- (LVEDD;d)3). N=4 per group.
