Pulmonary artery compliance: its role in right ventricular-arterial coupling.

abstract：:Regional myocardial anoxia was produced in dogs by perfusion of the left circumflex artery (LCA) with deoxygenated blood. Isolated sarcoplasmic reticulum fragments (cardiac relaxing system) showed decreased Ca2+ binding and uptake. The ability of isolated mitochondria to utilise long-chain fatty acids was markedly red...
