1. The coronary blood vessels surrounding the heart have derived their name from the fact that they encircle the heart like a crown, or corona. These vessels transport almost a half pint of blood every minute over the surface of the heart. Any sudden blockage of one of the coronary arteries deprives that section of the heart of its blood supply. Cardiac cells die, heart contractions may cease, and circulation may come to a standstill. If a coronary artery is completely plugged, the condition is called a coro-

nary occlusion or heart attack. The vascular pathologic disorder itself has been very variable. If the obstruction is only partial or in one of the smaller coronary tributaries, prompt treatment often leads to the individual's recovery. An occlusion in main coronary arteries is very serious and may cause sudden death. Other causes of the coronary disease in-
clude heavy physical exercise, aging, dietary habits, obesity, smoking, or hypertension.

2. Pain which had been developed in the heart may be due to a bloodflow deficiency in the coronary vessels. This is referred to (actually felt in) the left arm and shoulder. Such pain from the heart has been called angina pectoris. Angina pectoris may not actually be noticed until the work load is too great in relation to the flow in the coronary vessels. People who had experienced it repeatedly often do not feel pain unless they experience strong emotion. Others experience it much of the time.

3. Fortunately, the great majority of coronary disease patients will have recovered and have been able to lead active, useful lives, when they receive proper treatment under good medical supervision. There are many preparations which have been effective and are under clinical investigation at the present time.


4. Heart and artery diseases have been presently the number one health problem in the world. Cardiovascular ailments are by far the chief

causes of illness, disability, and death among both middle-aged and elderly people. Among these, coronary heart disease, illness of the blood vessels supplying the heart, is responsible for the greatest number of deaths (over 50 per cent of all cardiovascular diseases). Causes of other cardiovascular disease deaths, in order of decreasing importance, are stroke and hypertension. These three diseases are responsible for more than 80 per cent of all cardiovascular disease deaths.

5. Like cancer and emphysema, heart diseases appear to be related to the extension of the average life span. Certain factors are definitely involved in the high incidence of heart disease - the stress, diets high in saturated fats, the tendency toward obesity with age, lack of sufficient physical exercise, and the incidence of smoking. These factors appear to relate to a higher incidence of heart desease than in societies lacking these characteristics.

6. The severity and danger of heart and artery diseases which we had previously described cannot be minimized; a disease in an arm or leg may cripple a person, but a disease of the heart may lead to his death.

1. коронарных кровеносных сосудов вокруг сердца извлекли свое название от того, что они окружают сердце, как корона или corona. Эти суда перевозка почти половина пинты крови каждую минуту на поверхности сердца. Любое внезапное закупорки одного из коронарных артерий лишает этот раздел сердца его кровоснабжения. Сердечные клетки умирают, сердечных сокращений может прекратить и обращение может прийти к остановке. Если коронарные артерии полностью подключен, состояние называется Коро-ни капли непроходимость или сердечный приступ. Сосудистые патологические расстройства сам был очень изменчива. Если непроходимость только частично или в одном из небольших коронарного притоков, оперативное лечение часто приводит к его восстановления. Непроходимость в основных коронарных артерий является очень серьезной и может привести к внезапной смерти. Другие причины ишемической болезни в-заключить тяжелые физические упражнения, старение, пищевые привычки, ожирение, Курение или гипертонической болезни.2. боль, которая была разработана в сердце может быть из-за недостаточности кровотока в коронарных сосудах. Это называется (на самом деле чувствовал в) левую руку и плечо. Такая боль от сердца называется стенокардией. Стенокардия может фактически быть незамеченной до тех пор, пока Рабочая нагрузка слишком велика по отношению к потока в коронарных сосудах. Люди, которые пережили его неоднократно часто не чувствуют боли, если они испытывают сильные эмоции. Другие испытывают это много времени.3.
