Second: the need for limiting the amount and type of exercise taken, especially after eating, since the work of digestion requires all the power and strain of which the heart is capable, and since an additional tax placed upon it by muscular exertion might readily be just the final straw, the added fraction which weighs down the balance on the scale of life. Third: the advisability of abstaining from alcoholic beverages, unless specially prescribed by the physician in charge. Certain elderly people suffer from a condition known as senile heart, which is more or less associated with arteriosclerosis and high blood pressure. These individuals should be prevailed upon to take the precaution of regulating their habits of life, avoiding excesses of all kinds, not only on account of the weakened condition of the heart, but also on account of the condition of the arteries. They should avoid excitement and worry, since the very fact that they are worrying increases the blood pressure. Simple foods in limited quantities, five meals a day instead of three, and an avoidance of too much fluid, should be the keynote of their daily regime. Tact on the part of the nurse is necessary in all cases, both young and old. It is often more difficult to instill good dietary habits in heart patients, after acute symptoms have subsided, than to carry them out during the acute attack, when the life itself depends upon a rigid adherence to the diet prescribed. But as these rules and regulations are essential to the future welfare of the patient, he must be taught with care, and in such a way that he will not be alarmed to an extent when more harm than good will come of the teaching. The diet should consist chiefly of milk, eggs, rare meat in moderation (mutton, chicken, fish, and oysters), well-baked bread, well-cooked cereals, potatoes and green vegetables, and simple desserts. All foods which in any way cause gastric or intestinal disturbances must be avoided. If these disturbances arise during the course of the disease, the patient should be promptly returned to the strict milk diet. When edema is prominent, it is treated as already described in the treatment for the like condition in nephritis by the Karell or salt-free diet. The dietetic treatment given here is merely a guide to be used under certain conditions. The physician formulates the diet, and the nurse must understand what to expect and how to apply the treatment as the symptoms arise. SUMMARY ~Dietetic Treatment~, adjusted to relieve the weakened heart muscles and to save the organ from all possible strain. ~Three Stages~, during which the treatment changes according to the extent and progress made by the disease. First Stage: The diet is practically normal. Compensation is good, consequently no dietary measures save the limiting of alcoholic beverages are necessary.
