There are a number of CVD known to man. One of the most common disorders is termed arteriosclerosis.
Arteriosclerosis is a generic term covering a number of diseases of blood vessels.
As a result of these structural changes there is a dysfunction in blood flow. One of the primary symptoms is elevated blood pressure. Blood pressure is usually elevated because the diseased arteries can no longer expand to allow larger volumes of blood through, particularly during periods of physical labor. Individuals stricken with this disorder usually experience undue fatigue when walking up a flight of stairs, for example. The most important type of arteriosclerotic disease is a condition called athero sclerosis.
