[Left ventricle dilatational lesion. Problems of nosology, diagnostics, and treatment].

The article deals with the problem concerning the use of the term "specific cardiomyopathy", adopted by WHO in 1995, in cases of advanced left ventricle lesion in patients with valvular heart defects. The group of patients with dilated left ventricle cavity, related to acquired heart diseases, is rather heterogeneous and large in number, and includes about 50% of the patients who underwent an operation. In the authors' opinion, it is reasonable to divide them into the following main subgroups: patients with quickly regressing symptomatic left ventricle dilatation, resulting from volume overload; patients with valvular cardiomyopathy (the terminal stage of heart defect); patients with left ventricle dilatational lesion, typical of the intermediate stage with characteristic pathological remodeling and the disturbance of its segmental contractility. The authors consider such a division to be useful for further study of patients with left ventricle dilatation due to valvular heart defects.

[Changes in basic hemodynamic and electrocardiographic parameters in patients with severe vasorenal hypertension]. / Izmenenie osnovnykh gemodinamicheskikh i elektrokardiograficheskikh parametrov u bol'nykh s tiazheloi vazorenal'noi gipertenziei.

Major hemodynamic and electrocardiographic parameters were examined in 47 patients with severe vasorenal hypertension at rest, and in 20 patients after stress exposure. Three (hyper-, eu- and hypokinetic) types of circulation were demonstrated, like the ones seen in essential hypertension. Hemodynamic values at rest were indicative of relative cardiovascular compensation in severe vasorenal hypertension. Stress testing demonstrated that exercise disrupted that compensation. Arterial blood pressure response to physical stress showed no correlation to baseline values of the parameters examined.
