Neuralgia and the Diseases that Resemble it. Anstie Francis Edmund

СКАЧАТЬ History and Symptoms.– Cardiac neuralgia usually shows itself for the first time with considerable abruptness. The patient may or may not have been consciously ill before the actual seizure, but it rarely happens, even when the heart has notoriously been the subject of some organic disease, that there has been any thing to lead him to expect the kind of attack from which he now suffers. In the midst of some little unusual effort, or even without this kind of provocation, suddenly the patient is attacked with severe pain, usually at the lower part of the sternum; this pain darts through to the back and left shoulder, and nearly always runs down the left arm. Sometimes, indeed, it is felt acutely over a large area of the chest, and runs down both arms; this is the case in a patient now under my care, in whom the affection is more obviously a neurosis, and less attended with coarse organic changes, than is usually the case. Along with the pain, which is always very distressing, but varies greatly in severity in different cases, there is a variable amount of another sensation which can be compared to nothing but cramp, or rather compression; the patient usually describes it as feeling as if some one were grasping the heart in his hands, and, when this sensation is at all prominent, the idea of impending death is most strongly impressed on the sufferer's mind. His outward appearance seems to confirm the idea. In cases where the sense of compression is great, the face is of an ashen gray; the lips white, with a faint livid tinge; the pulse small, feeble, and unrhythmical, or imperceptible, at the wrist; cold perspiration breaks out upon the face; in short, all the signs of approaching dissolution are present. In cases where the suffering is chiefly or entirely confined to severe pain, of a darting or burning character, the state of the circulation is often different. The heart bounds against the ribs, in rapid and painful palpitation, the face is flushed deep crimson, the pulse at the wrist is large, bounding, but very compressible; in fact, the outward appearance of the patient is so different from that of one who suffers from the more depressing kind of angina, that it is difficult to consider the two affections as essentially similar. But there can be no question, if we carefully examine the matter, that they are mere varieties of the same disorder, especially as they both may successively occur in the same person.

      The course of cardiac neuralgia varies extremely. Supposing the malady to be purely neurotic, and not complicated with organic disease, which forms a constant source of cardiac embarrassment, then the patient may only experience one or two attacks, under some special circumstances of exhaustion, which may never recur; or, on the other hand, he may develop a strong tendency to cardiac neuralgia which may beset him during almost any number of years. In the latter case, it is an even chance whether the patient will at last sink from the anginal affection; for, even supposing him to escape any fatal intercurrent disease of an independent nature, the fatal event may be at last produced by cerebral softening, or by apoplexy, or other central nervous disease. In fact, the frequency with which the latter kind of termination occurs is very significant of the essential nature of the disease.

      The manner in which cardiac neuralgia commences varies very greatly. In the celebrated case of Dr. Arnold, the first attack did not occur till he was forty-seven years of age; it at once assumed full intensity, and proved fatal in two hours and a half. There is also reason to believe that Dr. Arnold's father died in a first attack of angina. I have myself known a first attack prove fatal in the course of an hour; there was very considerable ossification of the coronary arteries and fatty degeneration of the heart-walls. Again, there are many cases which commence gradually, and with great mildness, and with little appearance of danger to life in the first attacks; but the subsequent attacks are progressively more severe and dangerous up to a fatal result, after weeks, months, or years. On the other hand, I have known three instances in which the first attacks of spasmodic heart-pain very nearly proved fatal, but the subsequent fits were milder (in one there was no second attack): all those patients are living, six, eight, and three years respectively, after their first attacks.

      It can hardly be doubted that neuralgic spasm is the true cause of sudden death in some cases of stenosis of the aortic orifice, which, but for some accidental circumstances, would not have died suddenly at all, but would have gone through a long and gradual course of deterioration. I particularly remember an instance in which extreme and calcareous constriction of the aortic orifice, in a boy not yet come to puberty, was entirely unsuspected, until one day, in running fast, he screamed out and fell down, and was almost instantaneously dead. I remember another case very similar, in which extreme mitral constriction produced almost as sudden death, apparently from painful spasm, under the same kind of exertion. On the other hand, sudden death, when produced by the form of heart-disease which (as Dr. Walshe points out) is most likely to cause such a catastrophe, viz., aortic regurgitation pure, without hypertrophy, does not seem to be due to painful spasm, but to simple and complete failure of the muscular power, and is perhaps partly of the nature of paralysis from a syncopal condition of the brain, the unhypertrophied heart having become for the moment unable to supply blood enough to the brain to carry on nervous function at all.
