WebBlood Volume. In heart failure, there is a compensatory increase in blood volume that serves to increase ventricular preload and thereby enhance stroke volume by the Frank-Starling mechanism. Blood volume is augmented by several factors. Reduced renal perfusion results in decreased urine output and retention of fluid. WebRenal perfusion is reduced in heart failure, and prostaglandins become increasingly important in controlling renal plasma flow and fluid homeostasis. NSAIDs, however, reduce prostaglandin synthesis, thus decreasing glomerular filtration and resulting in salt and water retention. 214,228 NSAIDs act by inhibiting both COX-1 and COX-2.
