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.
There are some major types of heart diseases:
1. Type of heart disease affecting heart chambers
As we mention in the previous 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 needs. The malfunctioning of the heart chambers are due to damage caused by narrowed or blocked arteries leading to the muscle of your heart.
There are 4 heart chambers as follow:
The right atrium
The left atrium
The right ventricle
The left ventricle.
Heart diseases affect the heart chambers include:
A. 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 needs. The malfunctioning of the heart chambers are due to 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 ability 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 normally does as a result of more blood remaining in the lower chambers of the heart.
B. 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.

2. Heart Disease affecting heart muscles
In the case of heart diseases affecting heart muscles, the heart muscles are stiff, increasing the amount of pressure required to expand for blood to flow into the heart or the narrowing of the passage as a result of obstructing blood flow out of the heart.
Heart diseases affecting heart muscles include:
1. Cardiomyopathy
Heart muscle becomes inflamed and doesn't work as well as it should. There may be multiple causes such as high blood pressure, heart valve disease, artery diseases or congenital heart defects.
a) Dilated cardiomyopathy
The heart cavity is enlarged and stretched. Blood flows more slowly through an enlarged heart, causing formation of blood clots as a result of clots sticking to the inner lining of the heart, breaking off the right ventricle into the pulmonary circulation in the lung or being dislodged and carried into the body's circulation to form emboli .
b) Hypertrophic cardiomyopathy
The wall between the two ventricles becomes enlarged, obstructing the blood flow from the left ventricle. Sometimes the thickened wall distorts one leaflet of the mitral valve, causing it to leak. The symptoms of hypertrophic cardiomyopathy include shortness of breath, dizziness, fainting and angina pectoris.
c) Restrictive cardiomyopathy
The ventricles becomes excessively rigid, so it's harder for the ventricles to fill with blood between heartbeats. The symptoms of restrictive cardiomyopathy include shortness of breath, swollen hands and feet.
