Atherosclerosis

Arteriosclerosis is one of the most common diseases of the blood vessels. It refers to a thickening of the walls of the arteries due to the presence of calcium or lime. It has become a common ailment in modern times, accounting for much of the disability and high death rate among older people.

Arteriosclerosis is usually preceded by artherosclerosis, a kind of degeneration or softening of the inner lining of the blood vessels walls. The most risky places for such degeneration are the coronary vessels of the heart and the arteries leading to the brain. Arteriosclerosis results in the loss of elasticity of the blood vessels, with a narrowing of the smaller arteries, which interferes with the free circulation of the blood. These changes may gradually extend to capillaries and veins.

Arteriosclerosis is more frequent in men than women, especially in the younger age-group. It has been estimated that 40 per cent of all men over 40 years have a significant degree of obstruction of their coronary arteries and this can lead to heart attack at any time.
