What does a hyperdynamic left ventricle mean?
A hyperdynamic left ventricle (ejection fraction ≥ 70%) seen on stress radionuclide myocardial perfusion imaging bears strong association with diastolic dysfunction and is therefore a marker of heart failure with preserved ejection fraction in appropriate clinical setting.
Is hyperdynamic left ventricle serious?
In conclusion, the finding of a hyperdynamic LV is likely a sign of decreased preload to the LV rather than a sign of hypovolemia or sepsis. Close observation of the RV is important in patients with a hyperdynamic left ventricle, a potential sign that the patient has right-sided heart failure.
What is Hyperdynamic cardiac function?
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 ejection fraction?
Too high EF (more than 70%), which is called a hyperdynamic LVEF, is commonly found in patients with trauma in the intensive care unit [33]. Reduced EF in heart failure is caused by muscle damage that remodels the cells and reduces contractility.
What causes a hyperdynamic heart?
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.
How is Hyperdynamic treatment?
For hyperdynamic cardiovascular changes, administration of a combination of beta-blockers with sympathetic alpha-blockers is most effective in reversing this venom-induced effect. Avoid using beta-blockers alone because this leads to an unopposed alpha-adrenergic effect.
Is Hyperdynamic circulation serious?
Through a complicated and not completely defined series of events, this increased portal venous pressure leads to the development of a complex and dangerous cardiovascular condition termed the ‘hyperdynamic circulation.
How do you treat high cardiac output?
Many of the causes of high-output heart failure are curable. It’s a good idea to treat the underlying cause first. Your doctor may suggest other treatments, including a diet low in salt and water. You may also take diuretics (water pills) to help ease swelling.
