Values are expressed as mean ± SEM. HW, heart weight; BW, body weight. LVEF, left ventricular ejection fraction; LVFS, left ventricular fractional shortening; LVIDd, left ventricular internal diameter at end-diastole; LVIDs, left ventricular internal diameter at end-systole. BK, bradykinin; PC, preconditioning; HOE, HOE140; LY, LY294002.
