Relationships between the prevalence of electrocardiographic high-amplitude R and S waves, the stroke index, mean hemodynamic arterial BP and left-ventricular myocardial thickness (MT) were examined in a population of 411 individuals, aged 35-64 years. The prevalence of those waves is shown to have independent functional relationships with the stroke index and mean hemodynamic BP, irrespective of left-ventricular myocardial morphology. This functional approach is used to explain the causes of low sensitivity of electrocardiographic signs of left-ventricular myocardial hypertrophy when used for diagnostic purposes at population screenings.

The authors studied the data of echocardiography performed at the district diagnostic center rendering services for 337000 adult population. Altogether 487 patients were referred to the center for echocardiography. The main portion of the patients included 398 persons (81.7%) with suspected heart disease and prolapse of one of the cusps of the mitral valve. 326 persons (66.7%) were under 39 years. The experience in the use of echocardiography under the conditions of the specialized polyclinics (the diagnostic center) has shown the high efficacy of the technique during examination of the patients at the prehospital stage.

The obtained experience of echocardiography use in wide population examinations demonstrate that it is of practical value for diagnosis of lesions of heart valves or other heart structures (about 10% of pathology in grown-up population). The efficacy of the method could be highly increased (from 37% to 81%) if the investigation was performed in patients with murmurs above the heart area, with cardiovascular diseases in anamnesis and with marked ECG alterations. Children and adolescents exhibited mainly various types of mitral valve prolapse.

ECG assessment after the Minnesota code with defining "definite" CHD and "expected" CHD was used as one of the criteria of establishing diagnosis in mass screening of the population to find out CHD prevalence. A profound clinico-instrumental study of 100 men aged 20 to 59 with "expected" CHD showed that in 16% ECG-changes reflected true CHD, in 42% they were determined by noncoronarogenic causes. In 42% of the cases cardiovascular pathology was undetectable among the persons with "expected" CHD. Significant incidence of the noncoronarogenic pathology in the population is of interest to research.

The study analyses the results of examinations of 8 patients with cardiac myxoma (5 men and 3 women ranging from 21 to 54 years of age). In 6 patients, the tumour was localized in the left atrium, in 2 in the right atrium. The results of clinical, laboratory and instrumental examinations are analyzed, with special attention to ultrasound sectoral scanning, which proved to be particularly suitable for diagnostic purpose. Seven patients were successfully operated, one patient died postoperatively from thromboembolic complications.

Subcutaneous nodules on the leg were found in 40 (16%) of 250 male cardiologic in-patients, aged 17-65; they correlated, with a significant frequency with increased skin distensibility, overextension of the fingers and breast-bone deformation, mitral valve prolapse and atrial fibrillation. This feature can be used in the diagnosis of inherited generalized connective-tissue dysplasia.

In 57 patients with stenosis or occlusion of the terminal segment of abdominal aorta the authors measured the myocardial mass and the end diastolic volume of the left ventricle before the operation and 15-20 days after it (shunting or prosthesis of bifurcation of the abdominal aorta). Prior to operation increase of the myocardial mass of the left ventricle was found in 77.2% of patients. Patients with normal blood pressure had an increase in the myocardial mass at the expense of the thickening of the ventricular wall only, in patients with increased BP there was an increase in the thickness of the ventricular wall and also in the end diastolic volume. After the operation in patients with normal BP myocardial mass of the left ventricle reverted to normal. In patients with high BP the myocardial mass and the end diastolic volume of the left ventricle decreased. Myocardial hypertrophy in the patients studied is due to the increased resistance to blood ejection from the left ventricle caused by stenosis or occlusion of the abdominal aorta.
