What a great distinction there is between this mode of looking at these diseases and the German method was pointed out by Prof. Lindwurm of Munich, when he translated Prof. Stokes' work on the heart into German. Prof. Lindwurm said:
Thus our modern German works are to a greater or lesser extent only treatises on the physical diagnosis of organic affections of the heart. Stokes, on the contrary, resists this one-sided tendency which bases the diagnosis solely on physical signs and disregards the all-important vital phenomena; he lays less weight on the differential diagnosis of lesions on the several valves and on the situation of a sound than on the condition of the heart in general, and especially on the question as to whether a murmur is organic or inorganic, and whether the disease itself is organic or functional.
Broadbent on Cardiac Diagnosis.—What Stokes taught the English-speaking world so emphatically in the first half of the nineteenth century Sir William Broadbent was just as insistent about in the latter half. It is evident, then, that clinical experience has not changed its viewpoint in these matters in spite of all our study of the heart in the interval. In his paper on "The Conduct of the Heart in the Face of Difficulties" he has many suggestions that will prevent the physician of less experience from taking too pessimistic a view of heart symptoms. He said:
Moreover, the heart has very special relations with the nervous system; it reflects every emotion, beats high with courage, is palsied by fear, throbs rapidly and violently with excitement, and acts feebly under nervous depression; but it is not only through the cerebro-spinal system that the heart is influenced, it is in immediate relation with the vasomotor nervous apparatus, and in a scarcely less degree with the sympathetic system generally. Normally, afferent impulses are constantly flowing from the viscera to the central nervous system and by this reflex process their blood supply is regulated, and their functional activity is governed. These afferent impulses when perverted by functional derangement or disease may become serious disturbing influences.
The nervous system in a large and increasing proportion of people is unduly sensitive and excessively mobile, and the reactions to influences of every kind are exaggerated. In some a little emotional excitement gives rise to palpitation, and a piece of bad news or the bang of a door seems to stop the heart altogether. There is in such subjects no form or degree of cardiac disease which may not he simulated. [Italics ours.] Add a touch of hysteria on the lookout for symptoms and for someone to give ear to the narration of the unparalleled agonies of the sufferer, and the difficulties of the heart, and it may be added of dealing with them, are complete.
Typical Case.—We are prone to think that after the age of seventy the existence of definite heart murmurs with some tendency to blueness of the lips and of the fingers, with coldness of the hands, surely indicates the presence of a serious heart lesion. It is in old people, however, that such symptoms may be most deceptive. The outcome may prove that physical signs ordinarily presumed to be surely indicative of organic disease may be only signs of functional disorder, or at most may represent certain organic affections for which even the old heart is thoroughly capable of compensation. One such instance in my own experience is so striking that I venture to give it in detail.
This was the case of an old physician friend of some eighty years of age. His son had a summer lodge in the Adirondacks. Though for some sixty years the father had been living at the sea level in New York almost constantly, he went up to visit the son and be with his grandchildren at an elevation of nearly 2,500 feet. His heart began to bother him almost at once and he could not go up or down stairs or take any exercise without considerable discomfort, marked shortness of breath and a tendency to palpitation that was almost alarming. He continued his stay for several months in the hope that he would get used to the altitude, though there were always difficulties of circulation manifested by blue lips and finger nails. He returned to New York and placed himself under the care of a heart specialist who found what appeared to be evident signs of heart deterioration of muscular character complicated by valvular lesions. He consoled, the old gentleman by the reflection that a heart that had served his purposes so well for eighty years could not really be complained of if now it should show some signs of deterioration. He also insisted that any mental work would be almost sure to be injurious because of the calls upon the circulation that it would make.
The old gentleman was ordered South for the following winter with an absolute prohibition of any mental work. He had planned to revise an historical work on which he had been engaged for many years and which had served to keep him in good health perhaps more than anything else. This was put away entirely and he proceeded to try to get well doing nothing. Almost needless to say with nothing to do he did not get well. He had been an extremely busy man all his life, had worked at least twelve to fourteen hours a day for most of the preceding fifty years, and for him to do nothing would be quite as impossible as for a child to be kept in utter physical inactivity. His heart palpitation continued and grew worse. He was waked up at night by starts that seriously disturbed him and usually kept him from sleep for hours. As he said himself, after he had read the morning paper and gone to stool, there was nothing else for him to do all day except eat and sleep, and these incidents had never occupied any of his attention in the past. In spite of the doctor's orders he had his manuscript sent to him and proceeded to work. At once he began to grow better. At the end of three months he was feeling better than he had felt for several years. When I saw him, about his eighty-first birthday, he was looking better than he had for some time.
As he said himself in describing his case, his own experience had taught him that the more fuss a heart made the less likelihood was there of its having anything serious the matter with it, at least of such a character as would terminate life suddenly or unexpectedly. The serious heart lesions are those which give no symptoms, or but very slight ones, and the sudden deaths in heart disease usually come from the development of insidious symptoms that do not betray themselves to the patient until the fatal termination is on them. The more the patient himself has been disturbed by his heart, the less likelihood is there of its giving out suddenly. The subjective symptoms are usually due to the fact that the heart is actively overcoming external interference, or resenting over-attention to it in its work. Certain it is, that the neglect of it, so far as that is consonant with reasonably regular life, is the very best thing and the most important part of any prescription given for symptomatic heart disease, whether organic or functional, is to forget it just as far as possible.
