There is a circulatory overload which may lead to pulmonary edema secondary to an elevated diastolic pressure in the left ventricle. These individuals usually have a normal systolic function but symptoms are those of heart failure. With time, this overload causes systolic failure. Ultimately cardiac output can be reduced to very low levels. [1]
Hypervolemia, also known as fluid overload, is the medical condition where there is too much fluid in the blood. The opposite condition is hypovolemia, which is too little fluid volume in the blood. Fluid volume excess in the intravascular compartment occurs due to an increase in total body sodium content and a consequent increase in ...
Heart failure is usually associated with a volume overloaded state. Therefore, those with evidence of fluid overload should be treated initially with intravenous loop diuretics. In the absence of symptomatic low blood pressure intravenous nitroglycerin is often used in addition to diuretic therapy to improve congestive symptoms. [8]
“This has to do with fluid overload in the lungs as a result of the heart not pumping the way it should.” Fluid overload can also lead to swelling (or edema) in the legs or abdomen of people ...
Beyond this, there is volume overload, and stroke volume is diminished. Volume overload refers to the state of one of the chambers of the heart in which too large a volume of blood exists within it for it to function efficiently. Ventricular volume overload is approximately equivalent to an excessively high preload. It is a cause of cardiac ...
In the lungs, the extra fluid accumulates into the air sacs within the lung, causing difficulties in oxygen getting into the blood. This results in low blood oxygen levels and shortness of breath. In the arms and legs, the fluid accumulates in the tissues, causing swelling. This is most prominent in the legs due to the effects of gravity.
Aortic regurgitation causes both volume overload (elevated preload) and pressure overload (elevated afterload) of the heart. [14] The volume overload, due to elevated pulse pressure and the systemic effects of neuroendocrine hormones causes left ventricular hypertrophy (LVH). [9] There is both concentric hypertrophy and eccentric hypertrophy in AI.
In the heart, concentric hypertrophy is related to increased pressure overload of the heart, often due to hypertension and/or aortic stenosis. The consequence is a decrease in ventricular compliance and diastolic dysfunction, followed eventually by ventricular failure and systolic dysfunction. [citation needed]
