Understanding Heart Disease

Heart disease is a condition of heart disorder experiencing interference. The form of disorder itself can vary. There are disturbances in the heart's blood vessels, heart rhythm, heart valves, or congenital disorders born. The heart is a muscle that is divided into four spaces. Two rooms at the top are the right and left atrium. Two back spaces are located at the bottom, the right and left ventricle. Between the right and left chamber is separated by the muscular wall (septum) that serves to prevent the mixing of oxygen-rich blood with the blood of poor oxygen.

 The main function of heart is to drain oxygen-rich blood to all parts of the body. After all organs of the body use oxygen in the blood, the poor blood of oxygen returns to the heart (right atrium), to be forwarded to the right ventricle through tricuspid valve. After the blood meets the right ventricle, tricuspid valve will close the usefulness of preventing blood from returning to the right atrium. Then, when the right ventricle contracts, the poor blood of oxygen will appear from the heart through the pulmonary valve and the pulmonary artery, then brought to the lungs to be filled with oxygen. The blood that has been enriched by oxygen, after it is taken to the left atrium through the pulmonary vein. When the left atrium contracts, the blood is passed to the left ventricle through the mitral valve. Once the left ventricle is filled with blood, the mitral valve closes to prevent the blood from returning to the left atrium. Then, the left ventricle will contract, and the blood will be streamed to all the body through the aortic valve. The circulatory cycle will remain repetitive.

Types of heart disease
The term heart disease involves a wide range of disorders in the heart, among others:
Coronary artery disease (coronary heart disease) – narrowing of the heart blood vessels.
Arrhythmias – Disorders of the heart rhythm.
Congenital heart disease – heart abnormalities from birth.
Cardiomyopathy – disorders of the heart muscle.
Cardiac infections – infections of the heart due to bacteria, viruses, or parasites.
Diseases of the heart valve – disorders in one or four erroneous heart valves.
