M-mode echocardiography. a Representative echocardiography images of sham-operated, DMSO-treated, and tadalafil-treated mice at 28d post-MI. b Fractional shortening. c Anterior Wall Diastolic Thickness. d Left ventricular end diastolic diameter. e Left ventricular end systolic diameter. Tadalafil treatment ameliorated left ventricular remodeling following permanent coronary occlusion at 7 and 28 days by reducing dilatation, preserving fractional shortening and anterior wall thickness, P<0.05 vs. saline at 7 and 28 days post-infarction; n=5–9/ group
