Vectorcardiographic analysis of the QRS loop in hypertensive heart disease.

The authors made a quantitative and qualitative vectorcardiographic analysis (Frank lead system) in 47 patients with hypertensive heart disease compared with a control group of 16 normal subjects. The magnitude and the angle of the maximum QRS vector, the sense of rotation of the QRS loop, the magnitude of the maximum posterior deflection (Sz), of the anterior maximum one (Rz), of the maximum leftward one (Rx), and of the maximum rightward one (Qx), the length (L) and the width W) of the QRS loop, as well as the angle of the maximum T vector were measured. A significant difference, in all planes of the maximum QRS magnitude between the normals and the AHT was found, while the maximum QRS angle was not significantly different. The quantitative analysis of the veg made in the horizontal plane revealed significant differences for the Sz, Rx, L, and the relation Rz/Sz. The quantitative analysis made according to Varriale et al. (1966) revealed a prevalence of the cases of type I A (72.3%) and I B (21.3%).

Blood and cerebrospinal fluid catecholamines in the chronic obstructive bronchopneumopathy.

In our research we have aimed at studying the blood- and cerebrospinal fluid catecholamines' behaviour by means of von Euler-Floding's method, in a group of 30 patients, between 33 and 83 years, with chronic obstructive bronchopneumopathy, evolving from over ten years (even in younger persons). The total catecholamines in the cerebrospinal fluid have double values as against those in the blood, corresponding to the proportion found in a group of healthy subjects. On the contrary, the catecholamine fractions, occurring both in the blood and in the cerebrospinal fluid, have a diffent behaviour as against the normals, the adrenaline percentage exceeding by far the value of 23% recorded by these latter, going up to 46.95% in the blood and up to 47.68 in the cerebrospinal fluid. The increase of the adrenaline percentage may represent a pathogenetical factor, added to the other metabolic and hemodynamic factors, in the genesis of the chronic cardiopneumopathy; and the noxious effect acting on the whole myocardium supports the thesis according to which, earlier or later, in chronic obstructive bronchopneumopathy the left ventricle starts to suffer, as an integrant part of the clinico-morphological image.

Investigations on some coagulability tests in atherosclerosis.

Coagulation and fibrinolysis were investigated in a group of atherosclerosis patients, a group of neonates and a control group, determining the clot retraction time, the amount and quality of the blood platelets, and euglobulin lysis time. The results showed that fibrinolytic activity values are about equal in the two experimental groups, whereas clot retraction time, number of thrombocytes, thrombocyte adhesiveness, and agglutination sharply differed. Hyperadhesiveness and hyperagglutination were found in 75% of the atherosclerosis patients, with a clot retraction time of 79% and 290,000 thrombocytes/mm3 as compared to the hypoadhesiveness and hypoagglutination found in all the neonates, in which clot retraction was 43% and the number of thrombocytes 115,000. All values differed from those of the control lot.
