In the modern understanding, thoracic toad (angina pectoris) in its typical manifestation is pain behind the sternum or in the heart area, arising due to a lack of oxygen in the heart muscle, in most cases caused by the fact that the request for blood flow from the heart muscle exceeds its flow through the coronary vessels. The latter is usually caused by damage to the walls of the arteries of the heart, most often by their atherosclerosis. Violation of coronary blood flow may be the result of dynamic changes (spasm) in a certain area of the coronary system. But sometimes the need for oxygen exceeds its usual size, and this also causes pain in the heart area. Such conditions arise as a result of an increase in the intake of catecholamines into the blood, which has been reported by many, and first of all by Raab. Various experiences also lead to an excessive intake of catecholamines into the heart. The resulting metabolic disorders in the heart muscle can manifest pain. The variety of mechanisms leading to breast toad makes it difficult to prevent it.
