cardiovascular system
• hearts exhibit enlarged papillary muscles of the left ventricles
• however, no myofibrillar disarray is seen and heart weight to body weight ratios are normal and do not indicate cardiac hypertrophy
• hearts exhibit enlarged interventricular septa muscle
• myofibrils from ventricular, septal, and papillary muscles exhibit an increase in the calcium sensitivity of force
• however, no significant difference in the kinetics of calcium-dependent activation and calcium-dependent relaxation is seen in papillary muscle fibers
• echocardiography does not show any differences, with left ventricular chamber dimensions in systole and diastole, and ejection or shortening fractions similar to controls
