The question as to the permissibility of marriage to girls and women affected with heart disease cannot, in fact, be answered by any general proposition; and each case demands separate inquiry and a careful balancing of individual considerations. I have known cases in which the marriage of young girls suffering from morbus cordis was equivalent to a sentence of death, the execution of which was delayed for a few months only. On the other hand, I have known many women belonging to the upper classes and suffering from cardiac defects to pass through numerous pregnancies and to give birth to a number of children with no more than trifling disturbances of compensation. I am acquainted with a lady who when a young girl was urgently advised against marriage, on account of extensive aortic valvular incompetency, by two celebrated physicians. The advice was disregarded, and this lady is now the mother of four children, the eldest of whom is twenty-two years of age, and her general condition is in no way worse than it was before her marriage. The dangers of marriage in women suffering from morbus cordis are in my opinion generally overrated.
The degree to which a woman affected with heart disease will be injured by married life, will depend on the nature of the cardiac affection, on the time it has already existed, on the adequacy of compensation or the intensity of existing disturbances of compensation, on the general state of nutrition of the patient, on the more or less favorable social position, and on the manner in which sexual intercourse is regulated.
My own opinions in respect of this question may be summed up as follows: A woman who has comparatively recently (within a few years) acquired a valvular defect, and in whom the disease has run such a course that, in consequence of dilatation of certain chambers of the heart and of hypertrophy of those segments of the myocardium on which increased work has been thrown, and thus in consequence of adaptation of the cardio-vascular apparatus to the new conditions, the circulation and distribution of the blood take place in a manner closely resembling that in which these functions are effected in a normal, healthy individual—in a word, a woman in whom the valvular disease appears to be adequately compensated,—if, in addition, the patient is well nourished, if the hæmatopoietic function has not undergone any notable disturbance, if the muscular system is powerful and the nervous system possesses sufficient power of resistance—then marriage may be permitted without hesitation. In the case of such a girl or woman, we can confidently assume that the adequate compensation of the valvular disease will enable the heart to meet with success the claims made upon its reserve energies by sexual intercourse, by pregnancy, and by parturition, and that these processes will not involve any excessive danger to life.
A woman with valvular heart disease, even when that disease is well compensated, will indeed during pregnancy and still more during parturition and the early days of the puerperium, be liable to suffer from various manifestations of cardiac disorder. The action of her heart will be subject to paroxysmal increase in frequency and force, sometimes also there may be transient attacks of cardiac asthenia; at the same time the breathing will become more frequent and deeper, and occasionally, even, there may be severe dyspnœa. Perhaps also symptoms of venous congestion may manifest themselves, digestive disturbances, sense of pressure in the head, swelling of the feet, œdema of the abdominal wall, even slight albuminuria. Just after childbirth, moreover, an abnormally intense depression of the circulation with infrequency of the heart’s action will be liable to ensue. In the great majority of cases, however, in which the conditions detailed above are fulfilled, the disturbances of compensation occasioned by pregnancy and the puerperal state will not seriously threaten life; and as soon as the puerperal period has been safely passed through, the heart will again be competent for its duties and will do its work as well as before.
These statements apply, not only to cases of well-compensated valvular disease, especially mitral insufficiency, mitral stenosis, and aortic insufficiency, but also to cases in which the heart has made a good recovery after an attack of pericarditis, and to cases of moderately extensive disease of the myocardium consequent on acute articular rheumatism or the acute infections.
As indispensable conditions for such a favorable prognosis, we naturally assume that the pregnant woman is in a position to command the extreme bodily care that in her condition is doubly needful, that she is able to avoid all severe physical exertion, and that she will be subjected to continuous medical supervision in respect of the adoption of suitable dietetic and hygienic measures.
Such a favorable prospect as regards marriage in cases of well-compensated heart disease will, however, be clouded in the case of women who are either very anæmic or predisposed to nervous disorders; nor is the prognosis favorable as regards women in whom the heart disease is either congenital, or acquired in early youth, or as regards women contemplating marriage when already well up in years.
For in very anæmic women, even when the heart is quite sound, frequently recurring attacks of tachycardia often occur during pregnancy, in the absence of any obvious exciting cause; œdema of the lower extremities, and the formation of extensive varices, are also common. Increased nervous reflex irritability has also an unfavorable influence upon cardiac innervation. In cases, again, in which the heart disease is of long standing, the functional capacity of the heart is so notably depressed that the organ is likely to prove incompetent to meet the increased demands made upon it by the processes of pregnancy. Finally, in elderly women, superadded to the valvular defects, we have the dangers dependent upon the already beginning arteriosclerotic changes in the bloodvessels. In all such cases, therefore, it will be the duty of the physician to advise his patient not to marry; and in any case to impress upon her mind the extreme probability, amounting almost to certainty, of serious aggravation of the heart disease by marriage, with permanent impairment of the general health.
In cases of valvular disease accompanied by serious disturbances of compensation, and in cases of notable degeneration of the myocardium in which pronounced symptoms of cardiac muscular insufficiency have made their appearance, marriage must be absolutely forbidden, as directly imperilling life. When even moderate bodily exertion suffices to cause palpitation, increased frequency of the pulse, and shortness of breath, when extensive œdema of the lower extremities is present and fails to disappear even after the patient has been strictly confined to bed, when the pulse very readily becomes irregular both in rhythm and force, whilst the urine is often scanty and contains variable quantities of albumin, when conditions of cardiac asthenia readily arise, characterized by a small, irregular pulse, coldness of the extremities, cyanotic tint, nausea, respiratory need,[[42]] and syncopal attacks—in all such cases, whether the symptoms just described are dependent upon valvular defects, upon pathological changes in the arteries, or upon diseases of the myocardium, in all alike the occurrence of pregnancy is a true disaster, which in the vast majority of cases causes a great and enduring aggravation of the disease, and frequently enough costs the patient her life.
Even in such cases as were previously described, in which, the heart disease not being severe, the patient was told that marriage was permissible, it is the duty of the physician to lay down certain rigid rules regarding sexual activity.
