Cardiac disease

“ What I wish to maintain is that in cardiac degeneration of any kind, in chronic cardiac dilatation, and in the enlarged heart of Bright's disease and of emphysema, just as in ordinary valvular disease, attacks of distress, alarming both to patient and doctor, often occur which call for nothing more in the way of treatment than attention to some intercurrent influence—an indigestible meal, loaded bowels, a nervous shock, a thoughtless effort, a passing hardship or nervous strain. Digitalis and its allies, strychnine, alcohol, nitrites, iodides and the rest are out of place in such an event. ”

“ What method might be followed with advantage in making a complete diagnosis of heart disease in older subjects?
A man of 60 consults us about his heart. He says that it has caused him a good deal of concern lately. More specifically he describes a sense of oppression behind the sternum as often as he exerts himself, and palpitation with consciousness of irregular [32] cardiac action when he goes to bed. We inquire for other familiar cardiac symptoms, such as pain, angina, fluttering, faintness, giddiness, and a sense of impending death. ”

“ Not only has the profession suddenly woke up to the recognition of a form of enlargement of the heart which was fully described fifty years ago by physicians in our own country, but the public have made "dilated heart" a fashionable disease which calls for the advice of a specialist and an annual visit to a Continental spa. We ought to have advanced beyond this stage of cardiac pathology long before this time. Besides, of how much greater interest is it in our every-day work to study the causes or circumstances that lead up to disease than the simple state of disease itself! ”

“ But when we come to consider cardiac strain a little more closely, it may be just as easily maintained that every dilated heart, every dilated cardiac chamber, every dilated blood-vessel has been strained. Whether, on the one hand, valvular disease, Bright's disease or emphysema, or, on the other hand, myocardial degeneration, has disturbed that cardinal condition of a normal circulation that the driving power must always exceed the resistance ahead, over-distension and dilatation of the cavities, with excessive stretching of their walls, constitute or consist in mechanical strain. ”

“ ETIOLOGY Rheumatism is the cause of most instances of cardiac disease which date back to childhood or youth, while arteriosclerosis and chronic infection cause most cardiac diseases in the adult. In the former case it is the mitral valve which is the most frequently affected, while in the latter it is the aortic valve. Any cause which tends to induce arteriosclerosis may be a cause of chronic endocarditis, such as gout, syphilis, chronic nephritis, alcoholism, excessive use of tobacco, excessive muscular labor and hard athletic work. Lead is also another, now rather infrequent, cause. ”

“ But you will remember that we have found that cardiac dilatation may be present in every kind of cardio-vascular degeneration; that the arteries are naturally enlarged and thickened after middle life, and that we refused to call these changes morbid. Clearly, therefore, a purely anatomical diagnosis of this sort is insufficient. If you are asked what the prognosis is of fatty degeneration of the heart, you answer that you must first be told whether syphilitic or gouty disease of the coronary arteries, or strain, or alcoholism, or phosphorus-poisoning or anæmia is the cause of it. ”

“ In anemia when the patient is active the heart is generally rapid. The rapid heart from cardiac disease has already been considered. For the palpitation or rapid heart Just described there is little necessity for other treatment than what the acute or chronic condition would call for. With proper management the condition will improve unless the patient has an idiosyncrasy for intermittent attacks of slightly rapid heart, as from 100 to 120 beats per minute. ”

“ The more carefully heart disease, and particularly individual patients affected by various heart lesions, have been studied in recent years the more it has come to be appreciated that the most important element in the treatment of organic heart disease is the definite recognition of the difficulty of exact diagnosis of most cardiac conditions and the unfortunate tendency to make the prognosis worse than it really is. Many heart affections are quite compatible with long life. ”

“ Any one of the many circumstances that produce cardiac failure and dropsy in chronic valvular disease may lead to embarrassment and fresh dilatation of the simply enlarged heart: anæmia and chronic disease, the acute specific fevers including pneumonia, emphysema, granular kidney, gout, syphilis, tobacco and alcohol poisoning, as well as anxiety and worry, and in women the advent of the menopause ”

“ No disease, perhaps, needs cheerfulness and pleasantness and lack of anxiety, or frets more than does cardiac weakness. A tuberculous patient may sit on a mountain top with snow blowing about him, and recover; a heart patient must have sunshine and comfort.
The results of such sanatorium treatment of heart disease are often evident not only to the patient by an increase of general muscle strength, the ability to do ordinary things and perhaps even sustain muscular effort without dyspnea and cardiac discomfort, but also to the physician by the physical signs. ”

“ Respecting the course of the cardiac disease, we are not furnished with sufficient information. It was no doubt very rapid, for the frame could not long endure symptoms of so violent a kind, and the disorder must of necessity soon have come to a crisis ”

“ Cardiac failure accounts for most of the deaths, whether developed gradually with dropsy, which proves to be intractable; or progressing rapidly with great cardiac distress, including angina; or occurring suddenly, as it often does. Aneurysm makes its appearance in other instances, of which the patient dies, or he is carried off by general paralysis or Bright's disease.
What prospect have we to hold out to the man who has strained the walls of his heart by muscular effort? ”

“ His experience is not uncommon, and probably every physician who sees many cases of heart disease can recall a few of them. Ten years ago I saw a man past seventy suffering from distinctly irregular heart action, though he gave the history of having had cardiac irregularity for some years at least, and he is still alive, past eighty, and with his heart irregularity still present. I have a patient over seventy whom I know to have had irregular heart action for fifteen years, and he himself is sure that it has been present since he was about forty, at least. ”

“ The treatment is aimed at chronic heart disease, to develop a greater cardiac reserve strength; the whole object of the treatment is to strengthen the myocardium, either in conditions of its debility or in conditions of diminished compensation in valvular disease. Any treatment that will develop a reserve heart strength to be called on in emergencies, more or less similar to the reserve strength of a normal heart, tends to prolong the patient's life and health. ”

“ While angina pectoris and edema of the lungs were not infrequent causes of death in men, it was a rare cause of death in women. Dyspnea is a frequent symptom, and one for which many patients seek medical advice.
A constant systolic blood pressure of over 200 shows a probability that the patient will ultimately die either of uremia or of apoplexy. Janeway found that those patients who are to die from cardiac weakness show cardiac symptoms early in their disease. ”

“ 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. ”

“ In such girls, in whom menstruation has appeared late and been irregular, or who are perhaps entirely amenorrhoeic, cardiac troubles may be so pronounced that the physician may be led to suspect the presence of organic disease of the heart. The most prominent symptom is frequent and violent palpitation, with strong pulsation in the carotids, respiratory distress, and feeling of anxiety, on continued exertion or even on very slight occasion. On percussion, the heart is not found to be enlarged ”

“ Working with dedication and determination, they have developed new treatments and procedures, such as cardiopulmonary resuscitation, defibrillation, clot- dissolving medicines, angioplasty, and cardiac imaging devices, that have saved many lives. As a result of these advances, the death rate from coronary heart disease has fallen dramatically in our Nation, with a nearly 60-percent reduction since its peak in the mid-1960s. ”

“ Actual enlargement of the organ may, however, result from prolonged over-action, as in Basedow's disease, in the smoker's heart, and the irritable heart of neurasthenics, but it is usually slight. Increased dulness in the cardiac area may be due to a variety of causes, some of which may simulate hypertrophy, as pericardial effusion, aneurism, mediastinal growths, or displacement of the heart from pressure or the existence of malformation of the chest; but with the exercise of ordinary care the diagnosis can usually be made. There are two opposite conditions which not infrequently give trouble. ”

“ In addition to extrinsic dangers, particularly those of Bright's disease, cerebral thrombosis and hæmorrhage, and bronchitis, failure of the heart is liable to supervene and prove fatal from the gravest of all intrinsic causes, namely, coronary degeneration. As this increases, the myocardium is steadily more and more impoverished ”

“ Diseases of the heart and blood vessels remain the number one killer in the United States, but we have made substantial and heartening progress toward reducing the devastating toll. Deaths from coronary heart disease have declined by 25 percent during the past decade. ”

“ Even inflammation of the lining membrane of the heart often exists without any obvious fever or other manifest symptom of illness, and in the dissecting rooms of medical schools nothing is more common than to find traces of pre-existing heart disease in patients whose whole life had been passed without the suspicion of such a malady. ”

“ The diseases affecting the pericardium by continuity or contiguity of texture are chiefly myocarditis, tubercle of the lung and mediastinal glands, cancer of the same structures, pleurisy, pneumonia, and cancer of the oesophagus. On fibroid disease of the heart pericarditis is a frequent attendant.3 The diseases affecting the pericardium by a special election, and which are remote from the membrane, are, principally, acute articular rheumatism, Bright's disease, inflammation and other diseases of the liver, phlebitis, typhus, typhoid and eruptive fevers, scurvy, and acute alcoholism. ”

“ Inflammation of the muscular structure of the heart occurs in limited, circumscribed areas, as evidenced by post-mortem examination, and it is probably always somewhat involved in connection with pericarditis and endocarditis. It may readily be inferred that if the whole organ were inflamed death would ensue immediately. Usually myocarditis results from the preexistence of blood poisoning or of some infectious febrile disease.
Symptoms.—The chief symptoms are those of heart weakness. The heart beat is fast, weak, and often irregular. Respiration is difficult and rapid. ”

“ Fifty years ago, a heart attack meant an end to an active lifestyle, and, for a third of those stricken, it meant death. Thankfully, the past half-century has brought us an array of advances in the prevention and treatment of heart disease. ”

“ More than 64 million Americans suffer from one or more forms of cardiovascular disease, including high blood pressure, coronary heart disease, congestive heart failure, stroke, and congenital heart defects. ”

“ As long as the circulation in the heart itself is good and not impaired by coronary sclerosis, and as long as this slowly developing chronic myocarditis has not advanced far, cardiac symptoms will not be in evidence; but if these conditions occur, or if the blood pressure is so greatly increased as to damage the aortic valve or strain and dilate the left ventricle, symptoms rapidly appear, and the heart must be carefully watched. ”

“ ETIOLOGY The cause of an irregularly acting heart in an adult may be organic, as in the various forms of myocarditis, in broken compensation of valvular disease, Stokes-Adams disease, coronary disease, auricular fibrillation, auricular flutter, cerebral disease, and toxemias from various kinds of serious organic disease. The cause may be more or less functional and removable, such as tea, coffee, alcohol, tobacco, gastric indigestion and intestinal toxemia ”

“ There are few among us whose lives have not been touched by the devastating effects of heart disease. Cardiovascular disease, which includes heart disease and stroke, takes one million of our citizens each year, and heart disease remains the single leading cause of death in this country. ”
