cardiovascular system
• left ventricle wall thickness at optimal volume is increased
• deposits of collagen in the right ventricle, left ventricle, and interventricular septum indicating cardiac fibrosis
• larger deposits of collagen are seen in calcified regions
• heart exhibits calcifications in the cardiac wall in most mice
• developed pressure, rate of pressure increase, and developed wall stress are reduced, suggesting that active force generation of the contractile apparatus is reduced
• heart exhibits lower developed pressure
• lower developed pressure is associated with a lower rate of pressure change (dP/dt) during the rising and falling phases of contraction
• heart exhibits increased diastolic pressures at all filling volumes
• active stress generated at maximal calcium concentration is lower in isolated skinned trabecular muscle
• the active force during the contraction of maximal calcium concentration at the end of the determination of calcium-sensitivity is slightly lower in isolated skinned trabecular muscle
• however, the calcium-sensitivity of force is unchanged
