Angina pectoris, or angina, is most often characterized by pain in the heart and radiating in the left arm, associated with a feeling of anxiety. It is due to a narrowing of the caliber of the cardiac arteries (coronaries) causing a decrease in irrigation and thus oxygenation of the heart muscle. When these arteries are completely blocked, it is myocardial infarction.

The involvement of these coronary arteries is generally due to lipid deposits (atheroma). Its prevention is based on the fight against the risk factors of these plaques: diet low in saturated fats, regular practice of sports activities, cessation of tobacco as well as the fight against high blood pressure or diabetes

Treatment is based on medication management or surgery to prevent infarction in cases of greatest concern.
