摘要:

SummaryThe angiocardiography is one of the most interesting improvements of modern cardiology. This method is particularly useful in the study of congenital heart disease. In such cases it should always be used to complete the data obtained by other methods of cardiac investigation (catheterization, measurement of the pressures in the cardiac chambers and in the pulmonary artery, exercise test etc.).In the case of Fallot disease, it enables us to locate the malformations exactly, to know just the reciprocal position of the aorta and the pulmonary artery, to determine precisely their size and to visualize the sub-clavian arteries. These findings enable us to decide as to the advisibility of a surgical operation of this heart condition.The angiocardiography also gives us important data for the diagnosis of inter-auricular septal defect, patent ductus arteriosus, tricuspid atresia, coarctation of the aorta, and so on.The authors report some observations from their collection showing the interest of this new method of investigation.

摘要:

SummaryThe intra-venous injection of 75 mgr of nicotinic acid determines a fall of the intra-arterial blood pressure, usually starting two minutes after the injection and lasting for about 5 to 10 minutes. In the studied cases, the cardiac output increases from 6 to 150 % according to tho cases. A marked acceleration of the circulation (oxymetric method) was noted. Some patients presented an increase of the oxygen consumption probably due to the hyperpnea. The blood volume, studied by the Gregersen method (intra-venous injection of T 1824) did not show any important changes. The plasmatic volume, after nicotinic acid injection shows an average value of 98 % of its initial level. This difference has no statistical signification.The increase of the cardiac output can be partly explained (at least in some cases) by the increase of the metabolism. It is yet mostly due to the peripheric vaso-dilatation.Such circulatory modifications make the nicotinic acid unsuitable for the treatment of coronary diseases.
