What Is a Hyperdynamic Heart?

Hyperdynamic states are conditions in which the cardiac output is increased above the normal limits at rest. The normal adult range for cardiac index

is 2.3 to 3.9 L/min for each square meter of body surface, and the normal total cardiac output ranges from 4.0 to 8.0 L/min.

What causes hyperdynamic?

The hyperdynamic circulation begins in the portal venous bed as a consequence of portal hypertension due to the increased resistance to flow from altered hepatic vascular morphology of chronic liver disease.

What does hyperdynamic mean on Echo?

Hyperdynamic circulation is abnormally increased circulatory volume. Systemic vasodilation and the associated decrease in peripheral vascular resistance results in decreased pulmonary capillary wedge pressure and decreased blood pressure, presenting usually with a collapsing pulse, but sometimes a bounding pulse.
