Congestive heart failure is a pathophysiological condition in which the heart's output is insufficient to meet the needs of the body and lungs. [10] The term "congestive heart failure" is often used because one of the most common symptoms is congestion or fluid accumulation in the tissues and veins of the lungs or other parts of a person's body ...
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 .
Alright, so heart failure can affect the right ventricle, or the left ventricle, or both ventricles, so someone might have, right-sided heart failure, left-sided heart failure, or both (which is called biventricular heart failure), each of which can have systolic or diastolic failure.
Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing , leg or feet swelling, and fatigue. [1] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of multiple organs by fluid ...
The failure of ventricular relaxation also results in elevated end-diastolic pressures, and the end result is identical to the case of systolic dysfunction (pulmonary edema in left heart failure, peripheral edema in right heart failure). [citation needed] Diastolic dysfunction can be caused by processes similar to those that cause systolic ...
