Diseases that alter systolic cardiac function can become severe enough to overwhelm the ability of the cardiovascular system to compensate for the systolic dysfunction (primarily renal sodium and water retention, leading to hypervolemia, leading to increased venous return to the heart, leading to increased stretch on the myocardium, leading to.

This study sought to determine the hemodynamic effects of oxygen therapy in heart failure high dose oxygen has detrimental hemodynamic effects in normal subjects, yet oxygen is a common therapy for heart failure. Cardiovascular failure, inotropes and vasopressors dobutamine β1 agonist increased heart rate increased myocardial oxygen consumption. Such concentrations have only slight vasoconstrictive effect on cerebral vessels and produce a small increase in venous oxygen tension, and probably in cerebral-tissue oxygen tension as well whether such increases in oxygen tension are sufficient to maintain cellular viability in areas that would otherwise be incorporated in the infarct is.
