An
angina attack is often the result of atherosclerosis: they are
atheromatous plaque (deposition accumulation of various elements (fat,
blood, fibrous tissue, calcium deposits) that form the inner layer arteries, reducing their diameter.
The oxygen level made the heart decreases. The heart muscle hardly do his work, particularly in cases of stress, which causes pain in the chest.
The
pain is located behind the breastbone but may also radiate down the
left arm, back, top of the belly, in the neck, jaw or even teeth. Chest pain usually occurs during exertion, digestion or emotion, moments when the heart needs more oxygen.
