abstract：:The hydrostatic pressure (perfusion pressure) of the isovolumic isolated perfused rat heart regulated the hydrodynamics (water movement) of the myocardium. An abrupt (10 s) decrease in hydrostatic pressure caused an immediate decrease in oxygen consumption, left ventricular developed pressure, and wall thickness. Wall...

abstract：:An excess of thyroid hormone is known to produce cardiac dysfunction and failure, i.e., thyrotoxic heart. We studied the protective effect of coenzyme Q10 (CoQ10) on the thyrotoxic heart in 29 rabbits. A group treated with 1-thyroxine sodium salt (T4; 167 micrograms/kg) for 3 weeks showed marked decreases in the myoca...
