LV/BV, left ventricular weight to body weight; HR, heart rate; bpm, beats/min; LVEDD, left ventricular end diastolic dimension; LVESD, left ventricular end systolic dimension; FS, fractional shortening (LVEDD - LVESD)/LVEDD; IVSD, interventricular septum diastolic thickness; IVSS, interventricular septum systolic thickness; LVPWD, left ventricular posterior wall diastolic thickness; LVPWS, left ventricular posterior wall systolic thickness, EF, ejection fraction. Data are the mean ± SEM of number of mice shown in parenthesis.
