As we mention in the preceding article, the heart is a four chambered hollow muscle and double acting pump that is located in the chest between the lungs. Heart diseases caused by high blood pressure contributes to hardening of the arteries. High levels of bad cholesterol (LDL) build up in the arteries as a result of uncontrolled diet with high levels of saturated fat and trans fat. All these add to the formation of atherosclerosis lesions and eventually arterial blockage.
In this article, we will discuss heart disease affecting the heart chambers.

Heart failure is caused by the heart not pumping as much blood as it should and so the body does not get as much blood and oxygen that it requires. The malfunctioning of the heart chambers are because of damage caused by narrowed or blocked arteries leading to the muscle of your heart.

There are 4 heart chambers as follow:

• The left atrium




• 
  
  
  
• The right ventricle




• The right atrium




• The left ventricle.

Heart diseases affect the heart chambers include:

1. Congestive heart failure
Heart failure is caused by the heart not pumping as much blood as it should and so the body does not get as much blood and oxygen that it requires. The malfunctioning of the heart chambers are because of damage caused by narrowed or blocked arteries leading to the muscle of your heart.

a) Diastolic dysfunction:
The contraction function is normal but there's impaired relaxation of the heart, impairing its capability to fill with blood causing the blood returning to the heart to accumulate in the lungs or veins.

b) Systolic dysfunction:
The relaxing function is normal but there's impaired contraction of the heart causing the heart to not pump out as much blood that is returned to it as it typically does as a result of more blood remaining in the lower chambers of the heart.


2. Pulmonary heart disease
Pulmonary heart disease is caused by an enlarged right ventricle. It is known as heart disease resulting from a lung disorder where the blood flowing into the lungs is slowed or blocked causing increased lung pressure. The right side of the heart has to pump harder to push against the increased pressure and this can lead to enlargement of the right ventricle.
