[Cardiac tamponade from right ventricular rupture in severe lipomatosis].

A case of an 80 years old woman with II-degree obesity is presented. The patient showed no hemodynamic disturbances prior to her death despite bilateral cardiac overload causes by chronic pulmonary inflammatory processes and arterial hypertension. The rupture of the right ventricular cardiac wall with cardiac tamponade was due to the massive fatty infiltration of the cardiac wall and to the sharp increase of the hydrostatic pressure in the right ventricle in the course of pulmonary embolism.

[Clinical trial of the preparation clofazolin used intravenously].

The authors studied the hypotensive effect of the Bulgarian preparation Chlophazolin in ampoules of 0,15 mg, administered i. v. The study covered 50 patients, 44 of them with hypertonic disease II and III stage and the rest (6)--with renal and renovasal hypertension. The i. v. administration of chlophazolin was established to have a marked hypotensive effect and be expedient for the treatment of hypertonic crises and hypertension with high values. In a dose of 0,15 mg i. v. the preparation leads to a sharp decrease in the first 20 min, whereas during the following hours it is kept to lower values: systolic pressure-an average decrease of 30-40 mm Hb in a lying position, to 45-50 mm Hg in an erect position; the diastolic pressure-an average decrease of 10-15 mm Hg in a lying position to 20-25 mm Hg in an erect position. The hypotensive effect is better manifested in higher initial values of the pressure. It lasts approximately more than 13 hours but in 1/5 of the patients, with higher values of blood pressure, its effect is exhausted within 6-8 hours. Side effects of the preparation were registered in 26 per cent of the cases; orthostatic disturbances, sleepiness, dryness of the mouth, nausea. I. v. administration of chlopazolin does not change the excretion of urea and creatinine, diuresis and serum levels of sodium, potassium and chlorine.

[Anatomical and functional assessment of mitral stenosis using echocardiography before and after commissurotomy].

In 36 patients with pure mitral stenosis verified during catheterization and operation the results of echocardiography were compared with the operative findings. The changes in the mitral echogram and the degree of valve calcification before commissurotomy were studied. The hemodynamic changes in pulmonary circulation were approximately appraised by determining the degree of delay of the EF interval on the echogram of the anterior cusp of the mitral valve. Significant conformity between the dimished rate of diastolic movement of the anterior mitral cusp and the degree of mitral stenosis was established. The importance of the advancement of the posterior mitral cusp to the front of the horizontal line passing through point C of mitral valve closure in the appraisal of the degree of its stenosis is underscored.

[Effect of Production on the serum lipid and lipoprotein level in ischemic heart disease].

The serum lipids were dynamically followed up in 39 patients with ischemic heart disease treated with Prodectin. A gradual decrease of serum cholesterin is observed during the treatment period as well as of its content in alfa lipoproteins and of alfa lipoproteins themselves. A moderate decrease of triglyceride and total lipids develops in parallel with this, whereas free fatty acids considerably increase. In more than 1/3 of the patients the profile of hyperlipoproteinemia changed in the course of the treatment: the half of them turned to normolipoproteinemia, a number of the rest--into a more favourable type--II and IV type.

[Echocardiographic diagnosis of mitral stenosis].

One hundred forty nine subjects have their echocardiography recorded by Echoview apparatus, Picker firm. The echocardiographic parameters found in 72 patients in pure or almost pure mitral stenosis were confronted to those of 77 healthy subjects. The high sensitivity of the echocardiographic method is stressed upon in the differentiation of mitral stenosis. The most important echocardiographic criterion of mitral stenosis is the slowed down speed of the early diastolic movement, EF of the anterior mitral cusp and the shifting of the posterior mitral cusp forward from the line, passing through the point of the mitral closing. Confirmed diagnosis of mitral stenosis could only be obtained by the combination of those two echocardiographic changes. Echocardiographic significance is stressed in the establishment of the thickness of the two mitral cusps, increased number of component echolines and amplitude decrease in anterior mitral cusp opening in the assessment of the presence of mitral fibrosclerosis and calcinosis.

[Diagnostic value of the electrocardiographic changes during bicycle ergometer loading].

The diagnostic value of ST-T changes in working ECG on veloergometer with submaximal loading is assessed in 286 cases--83 with coronary disease, 44--healthy, 112 with indistinct precordial pains and neurovegetative dystonia and 46 with some other non-coronary heart diseases. The reduction of ST-segment 1 mm with horizontal or descending form is the most accurate criterium in the differentiation of pathological and normal ECG-reactions. An appropriate criterium for coronary disease diagnosis is also the negative T wave with an amplitude of 2 mm or more in at least three leads, regardless of its form and time of appearance. The reduction of ST segment with ascending form gives a considerable opportunity for positive false diagnosis. The false negative diagnosis is 24%. The causes are to be found in the appearance of rhythm and lead disturbances and insufficient loading.
