Rules and Regulations.—There are a few general rules which it has been found advisable to impress upon individuals suffering from a disease in which the muscles of the heart have become weakened. The compensation of the organ may improve, but there is still a danger of a reoccurrence or a further development more or less serious, and at times fatal. So for this reason, certain rules must be observed throughout life:
First: the necessity for keeping the meals small, simple, and digestible. Death at times occurs with symptoms of gastric disturbance, which is, after all, due to the heart. Consequently it is not wise to invite such disaster by overeating, or by the partaking of any food which is liable to bring about indigestion, either in the stomach or in the intestines. Most authorities advise four or five meals a day rather than the regulation three, and limit the fluids at meal time to a few ounces only, when any are allowed, and to a maximum amount of 1500 c.c. during the day, chiefly between meals.
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 régime.
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.
