Heart Symptoms in the Young.—In young people particularly it is important not to suggest the possibility of heart disease until there are definite signs in the circulation apart from the heart which place the diagnosis beyond all doubt. The psychotherapeutics of organic heart disease that is most important is that of prophylaxis. Patients' minds must be guarded as far as possible against disturbance from the thought that they have heart disease, for this of itself adds a new factor which tends to disturb compensation and adds to the heart's labor because worry interferes with the vasomotor mechanism. In this matter it seems advisable to repeat once more that there must be a complete reversal of the customs that have existed until now with regard to tuberculosis and heart disease. Consumptives have from the very nature of their disease a tendency to hopefulness which soon brings about a favorable reaction against the bad news, but heart patients derive no advantage from the announcement and, indeed, if they are of the nervous, worrying kind, the effect of it is likely to be cumulative. A week after being told the worst a consumptive has reacted vigorously and hopefully, and if he has a fair share of immunity, the scare will do good by making him take the precautions necessary to increase his resistive vitality. At the end of the same time a heart patient will be just realizing all the significance of the unfavorable diagnosis and prognosis of his case.
It may be urged that heart patients by knowing their condition will be preserved better from injuring themselves by over-exertion, but what we have said elsewhere about the value of exercise in the treatment of heart cases shows how much patients may be injured by having their exercise too much reduced and their activity inhibited by the dread consequent upon the announcement made to them. It is perfectly easy to insist with them that they shall not do sudden things, or take violent exercise, or overdo activity, without disturbing them by the dread words "heart disease."
CHAPTER III
CARDIAC NEUROSES
If, as all the authorities recognize, the attitude of mind toward organic heart disease is extremely important and when favorable is a most helpful therapeutic factor, it is easy to understand that in neurotic conditions of the heart this is of even more significance. The term "heart disease" is bound up with so many unfortunate and persistently unfavorable suggestions that it seems advisable not to use it with regard to non-organic conditions, even though it may be associated with the epithets functional or neurotic. For these the term cardiac neuroses, which avoids the implication of heart disease in the ordinary sense, seems preferable. Many of the cardiac neuroses are quite trifling. Many of them endure for years without producing any serious effect or disturbance of the general health. Many functional disturbances of the heart action which are extremely annoying may disappear entirely with judicious regulation of life. The one important condition in all of these cases is to be sure that the patient does not worry over the condition, for that [{322}] hampers heart activity and leads to functional disturbances of other organs which make the heart's work harder.
Varieties.—There are many forms of cardiac neuroses. Indeed, functional heart affections are so individual that it is hard to classify them. In every case it is extremely important to study the individual and recognize just what are the special factors bringing about the disturbance of heart action.
Palpitation.—In a certain number of the cases it will be found, indeed, that there is no real disturbance, but that in some way the heart action has been brought above the threshold of consciousness and has become noticeable to the patient. It must not be forgotten that the heart is an intensely active organ. Several gallons of blood are pumped through it every minute and yet it accomplishes its work, as a rule, with such noiseless, frictionless regularity that most people know nothing about it. When the action of the heart becomes conscious, it is usually spoken of as palpitation. Patients are sure to think that this must mean serious over-action, though, as a rule, no sign of over-action or at most a slight exaggeration of the muscular sounds of the heart will be found.
Missed Beats.—A further stage of this cardiac neurosis is the missing of beats. This occurs particularly in those whose attention has been directed for some time to their heart action by the presence of palpitation. It may be due to nothing more than this over-concentration of attention. It may be due, however, to mechanical disturbances, an over-distended stomach, constipation, or certain nervous factors.
Arrhythmia.—A third stage of cardiac neuroses consists of irregularity of the heart action, in which not only are the beats missed occasionally, but there may be certain heart sounds much less vigorous than others and the spaces between the sounds may be very unequal. This condition is usually said to be due to some serious condition of the heart muscles, and undoubtedly it often is. There is no doubt, however, that great irregularity of the heart may occur entirely as a neurotic condition without any organic affection and from factors quite extraneous to the heart itself.
Etiology.—There are three causative conditions for cardiac neuroses that deserve careful study and that can be very much modified by changing the attitude of the patient's mind toward his condition. The first of these is an over-attention to self such as is particularly induced by a life without much exercise and devoted to things intellectual. The direct causation is probably intimately connected with the second etiological factor in the production of cardiac neuroses. This consists of an absence of sufficient exercise for the heart itself, when it actually seems to disturb its own activity because adequate calls for exertion are not made on it to use up accumulated energy. Cardiac neuroses are seen particularly in those who having had considerable exercise in earlier years, have settled down to a sedentary life in which there are few calls made upon their muscular system. The third etiological factor is the most important. It is due to cardiac disturbance from the stomach and intestinal tract; this will be discussed in a [separate chapter].
Prognosis.—The prognosis in cardiac neuroses is always worse in the patient's mind than it ought to be. If then the physician shows that he is uncertain as to the real significance of the affection, some hint of this uncertainty will be communicated to the patient with resultant unfavorable suggestion. The [{323}] more carefully neurotic heart affections have been studied, the better the prognosis becomes. Morgagni in the olden time, Stokes and Corrigan in the early nineteenth century, Broadbent and MacKenzie in our time, have all emphasized the necessity for favorable prognosis. Even extreme irregularity is quite compatible with long life without any symptoms of serious circulatory disturbance. MacKenzie has, in his very careful studies of heart action, shown that extra systoles may cause marked irregularity in many forms without warranting unfavorable prognosis.
