摘要:

An evaluation of the management of patients with aneurysm of the aorta seems timely because of new and promising methods of treatment. The risks of nonoperative and operative treatment are presented from the experiences with 101 patients admitted to the Hospital of the University of Pennsylvania during the years 1950 through 1955. Follow-up data indicate that the mortality of nonoperative treatment is considerably greater than that of excision of the lesion, in spite of the poor operative risk of many patients in this group. The nonoperative mortality within 1 year of diagnosis was approximately 50 per cent. Many of these patients died of rupture of the aneurysm.

摘要:

Unusually comprehensive studies of pulmonary function in hypertensive patients during left ventricular failure and cardiac asthma are presented. These findings are compared to those in mitral stenosis with congestive failure and in pulmonary emphysema with right heart failure. All patients were severely dyspneic and bedridden.

摘要:

Clinical and experimental studies of acute myocardial infarction suggest that serum glutamic oxalacetic transaminase (SGO-T) levels may have both diagnostic and prognostic significance. The authors report their experience in 255 patients hospitalized because of chest pain strongly suggestive of acute myocardial infarction. The results of serial determinations are compared with the clinical data and the electrocardiographic findings. The data indicate that abnormally high levels have both diagnostic and prognostic significance.

摘要:

Although hypothermia is being used as an adjunct to general anesthesia, its cardiovascular effects in man are not fully known. In this report the authors present the hemodynamic changes observed in patients undergoing hypothermia under the clinical conditions of its practical usage in the operating room. Considerable variability in vasomotor and cardiac responses was encountered, indicating that uniform behavior of patients to this agent is not to be expected in the relatively uncontrolled operating room setting; therefore, it should be used conservatively, particularly in critically ill patients in whom unexpected reactions may be disastrous.

摘要:

Vascular responses to warming were studied in hemiplegic patients and after sympathectomy, using venous occlusion plethysmography of foot and leg. Comparisons were made with corresponding age groups. The pattern of response was essentially unchanged in hemiplegic patients, but was altered substantially where sympathetic pathways had been interrupted.

摘要:

Intracardiac surgery for rheumatic and congenital heart disease entails direct trauma to both normal and abnormal endocardium. This communication inquires into the incidence and nature of the endocardial infections that develop subsequent to this injury. On the basis of an examination of 2,263 patients operated upon for acquired and congenital heart disease during a 5-year period terminating in November 1955, bacterial endocarditis appears to be an infrequent complication of surgery, is caused by organisms not so commonly encountered in unoperated patients, and is characterized by a clinical pattern quite different from that ordinarily associated with bacterial endocarditis. The rate of attrition in this group of patients is high, and unquestionably is related to the antibiotic resistance of the unusual organisms and the severity of the basic heart disease.

摘要:

"Left heart" radiopotassium-dilution curves were carried out in 9 patients with rheumatic mitral valvular disease. From the curves, blood flow, circulation times, and "left heart" and aortic volumes were calculated. When this technic is used along with "left heart" pressure measurements, it appears to have a satisfactory reliability in demonstrating abnormalities of flow, volume, and mitral valve function. In theory, its proper application permits complete quantitation of these parameters.

摘要:

Dissecting aneurysm of the aorta is a not uncommon disease that usually produces severe symptoms and often leads to an early death. This article reports an unusual case in which the patient was nearly asymptomatic and died of unrelated causes. Autopsy revealed a healed dissecting aneurysm. The literature on dissecting aneurysm, emphasizing its pathogenesis and its relation to cystic medial necrosis, is briefly reviewed.

摘要:

Molar sodium lactate has been described as a safe and effective agent in the treatment of bradycardia accompanying complete heart block. However, in 12 patients with heart block, hypertonic lactate infusions produced ventricular tachycardia in 6 and an increased idioventricular rate in only 4. Isopropylnorepinephrine was more effective and without such hazard. The effects of alkalosis from molar lactate, 5 per cent sodium bicarbonate, and hyperventilation are compared. Of these 3, lactate was productive of the greatest ventricular acceleration.
