Question

One of the patent's discharge diagnoses is diastolic dysfunction which is a:

A) decline in performance of one or both ventricles of the heart when it is contracting to propel blood out of the heart

B) Condition that occurs when the lungs cannot remove all of the carbon dioxide the body produces. This causes body fluids, especially the blood, to become too acidic.

C) Decline in performance of one or both ventricles of the heart when it is relaxed and filling with incoming blood that is being returned from the body through the inferior and superior vena cavae

D) heart valve disorder of the pulmonary valve which seperates the right ventricle of the heart of pulmonary artery

Explanation / Answer

Decline in performance of one or both ventricles of the heart when it is relaxed and filling with incoming blood that is being returned from the body through the inferior and superior vena cavae

Blood from the lungs is carried into the left ventricle by the pulmonary vein and blood from other parts of the body is carried into the right ventricle. When the heart is functioning normally, blood from the lungs passes into the left atrium via the pulmonary vein and into the left ventricle. However, if the ventricle wall does not relax properly or is thick and stiff, the ventricle does not fill in the usual manner and blood is drawn back into the atrium and eventually into the lungs.

The abnormal stiffening of the ventricular wall and subsequent inadequate ventricular filling is referred to as diastolic dysfunction and when this leads to blood building up in other organs such as the lungs, diastolic heart failure is diagnosed.
