High-output heart failure is a heart condition that occurs when the cardiac output is higher than normal because of increased peripheral demand. There is a circulatory overload which may lead to pulmonary edema secondary to an elevated diastolic pressure in the left ventricle .
High-output heart failure can occur when there is increased cardiac demand that results in increased left ventricular diastolic pressure which can develop into pulmonary congestion (pulmonary edema). [46] Several terms are closely related to heart failure and may be the cause of heart failure, but should not be confused with it.
The main pathophysiology of heart failure is a reduction in the efficiency of the heart muscle, through damage or overloading. As such, it can be caused by a wide number of conditions, including myocardial infarction (in which the heart muscle is starved of oxygen and dies), hypertension (which increases the force of contraction needed to pump blood) and cardiac amyloidosis (in which misfolded ...
Stage A Defined as: At high risk for heart failure but without structural heart disease (defects in the heart from aging, injury, infection, or heart defect at birth), or symptoms of heart failure.
“Heart failure (also called congestive heart failure) is a terrible name which suggests the heart has stopped working completely,” says Anthony Steimle, MD, a cardiologist and assistant ...
When high pressure is pushing on the walls of narrowed blood vessels, fluid leaves the inside of blood vessels and moves to the space just outside. This impairs necessary blood flow and cuts off circulating oxygen, which can lead to tissue death and permanent damage to the brain, heart, arteries, and kidneys.
