摘要:

Eight clinically proved cases of prolonged thiamine deficiency were evaluated by routine pathologic study. The microscopic features were evaluated by comparison with sections of myocardium obtained from normal individuals and individuals suffering from cardiac diseases of other varieties. No specific transitory or permanent alterations were demonstrable. It is concluded that beriberi heart disease is largely the result of a reversible biochemical abnormality and is not characterized by specific pathologic lesions.

摘要:

Estimation of pulmonary blood flow relative to systemic blood flow is a critical point in selecting patients with ventricular septal defect and severe pulmonary hypertension for operation. A detailed medical history, physical examination, thoracic roentgenograms, careful interpretation of electrocardiograms, cardiac catheterization, and biopsy of the lung provide approaches to the problem. In borderline cases, decision still may be extremely difficult. The authors usually favor operation, however, with recognition that this decision may be in error. Obviously proper evaluation for operation cannot assure uniformly good results. Method of conduct of operation, perfusion, and postoperative care determine the results.

摘要:

Long-term treatment of hypertension with chlorothiazide alone produces mioderate reduction in blood pressure in 66 per cent of patients with hypertension. This fall in pressure is due to a reduction in total peripheral resistance rather than a fall in cardiac output.

摘要:

Secondary R waves in leads V1or V3Rare definitely abnormal if the primiary R wave is high for the age group even though the R′ is small; if the secondary R wave is more than 6 mm.; or if the R′/S ratio exceeds 1. Other patterns may be found both in patients with heart disease and in normal subjects. In the abnormal cases, the QRS changes persist in leads taken below but in line with V1and V3R; but in normal cases, the secondary R waves usually disappear in the lower leads.

摘要:

Renal function studies have been carried out in both the recumbent and in the oblique position in 2 cases of orthostatic hypotension. In both cases a definite fall in plasma flow and glomerular filtration rate took place, but this occurred only after registration of a considerable fall in blood pressure.The filtration fraction remains unchanged after the fall in blood pressure. The extraction ratio remains unchanged after a considerable fall in blood pressure.The data may indicate that the renal function becomes normal if blood pressure is kept on a low level over a fairly long period. However, further observations are required before any definite conclusion may be drawn.

摘要:

Chronic idiopathic pericardial effusion is an unusual condition that causes severe congestive heart failure and may be an early stage in the development of constrictive pericarditis. A case is reported and some other cases from the literature are reviewed in order to present the clinical features and treatment of this condition.

摘要:

It has been demonstrated that intracardiac phonocardiography provides precise localization of the source of cardiovascular sounds. Can this technic be of practical help in the diagnosis of small or complicated ventricular septal defects? Is a ventricular septal defect ever silent? What mechanisms are responsible for the diastolic murmurs in ventricular septal defect? In an attempt to answer these problems, intracardiac phonocardiograms have been studied in 47 cases.

摘要:

A study was made of the configuration of the elastic tissue of the pulmonary trunk in 6 cases of idiopathic pulmonary hypertension. The ages of the patients ranged from 12 to 54 years. The pattern was that of the adult pulmonary type in the 5 female patients, whereas it more closely resembled the fetal, aorta-like type in the single male patient. These data are interpreted as indicating that idiopathic pulmonary hypertension is acquired in most cases but that it may be present from birth in a minority of instances.
