[Exercise training of patients in a health resort after surgery for rheumatic heart disease].

We studied the effect of cardiovascular system function on the response to terrain cure in the course of rehabilitation of 88 patients after surgical correction of valvular defects in conditions of low-mountain health resort. We have found that the response to the above exercise depends on functional condition of the cardiovascular system (the degree of correction of hemodynamic disorders related to valvular disease, the degree of myocardial hypertrophy and dilation of the chambers, left ventricular contractility). Terrain cure exercise promotes improvement in regulation of cardiovascular system and mobilization of its reserves.

[Carbonate mineral baths in the combined treatment at a piedmont health resort of patients operated on for rheumatic heart defects].

The response of the cardiovascular system of 64 patients operated for rheumatic heart disease to mineral carbon dioxide baths was studied in the course of rehabilitation in low-mountain health resort. It was found that the above baths have a training effect on the cardiac muscle, improve myocardial metabolism. They are an essential factor in combined sanatorium treatment of patients after surgical correction of valvular defects.

[Changes in lipoprotein metabolism during the rehabilitation of ischemic heart disease patients after aortocoronary bypass at a health resort in the foothills].

284 patients with IHD after coronary artery bypass operation have undergone rehabilitation at low-mountain health resort Kislovodsk. The study of lipoprotein metabolism has detected a positive trend in this metabolism as shown by lowering of blood cholesterol, low density lipoproteins, phospholipids and triglycerides, elevated levels of high density lipoproteins.

[The rehabilitation of patients following the surgical treatment of ischemic heart disease at a low-altitude health resort].

We developed well grounded differentiated methods of rehabilitation treatment in low mountains for patients after surgery for ischemic heart disease. Evaluation of the results was carried out with due account for variety of clinical course of the disease, condition of coronary and myocardial reserves of the heart and concomitant diseases. 475 males aged 22-65 years who underwent aorto-coronary bypass surgery for CAD were examined.

[The reaction of the cardiovascular system to terrain cure in patients with ischemic heart disease who have undergone surgical myocardial revascularization].

Muscular training in IHD patients who have undergone surgical revascularization of the myocardium should be planned on the individual basis regarding functional condition of the cardiovascular system. Patients with reduced left ventricular contractility should exercise under Holter ECG monitoring to control episodes of ventricular arrhythmia.

[Changes in cardiovascular function of ischemic heart disease patients on the course of rehabilitation at low-mountain health resort after surgical revascularization of myocardium].

Sanatorium treatment at low-mountain resort of IHD-patients subjected to surgical revascularization brought an increase in exercise tolerance, a positive trend in ECG parameters, improvement in left ventricular myocardial contractility. The benefit is especially pronounced in patients with IHD of functional class I, II and normal contractility of the left ventricular myocardium.

[The dynamic clinical manifestations of ischemic heart disease during the rehabilitation at a low-altitude health resort of patients who have undergone surgical myocardial revascularization].

Left ventricular myocardial contractility was found essential in dynamics of clinical IHD picture in patients on rehabilitation treatment at low mountain resorts. All the patients have previously undergone surgical myocardial revascularization. Patients with normal left ventricular myocardial contractility benefited most of all.

[The terrain cure under moderate altitude hypoxia in the combined sanatorium-health resort treatment of patients with ischemic heart disease after aortocoronary bypass].

Muscular exercise in the form of terrain walking proved to be a useful component of combined conditioning of coronary heart disease patients after aortocoronary shunt functional class 1 and 2. In conditions of moderate altitude resort such training mobilizes cardiovascular reserves of CHD patients. The outcome of the above sanatorium rehabilitation depends largely on contractility of left ventricular myocardium.

The mitral valve replacement by the new-type bioprostheses (features of design and long-term results).

The BAKS bioprostheses were created in our centre and they have the following features: (1) to reduce immunogenicity they underwent a combined fermentochemical treatment which resulted in the native xenovalve consisting of collagen and elastic fibres only; (2) in cutting out the valve the natural aortic sinuses were preserved; and (3) the xenovalve was fixed on a functional frame of an original design. From 1979, BAKS have been implanted in 243 patients with the isolated mitral valve reumatic injury. The patients age varied from 11 to 59 years; 91 patients (37.

[The use of the results of current instrumental methods of cardiological examination in the sociomedical expert assessment of patients with rheumatic heart defects].

Altogether 103 patients with rheumatic heart disease were examined within different times after prosthetics of heart valves (mitral or aortal). The purpose was to elaborate the principles of applying the data of instrumental methods of cardiological examination to the improvement of disability criteria. The examination included echocardiography, tetrapolar chest rheography and ECG exercise test.

[The clinico-functional assessment and work capacity of patients undergoing repeated operations on the mitral valve].

A complex of examinations (ECG, echocardiographic and X-ray evaluations of heart volumes and cavities, treadmill-test) was performed in 82 patients before and after reoperations on the mitral valve. The type of recorrection was found to be associated with the degree of positive dynamics of the results. The data obtained contradicted to hyperdiagnoses of primary medical-labor examination commission establishing the II group of invalidism in 86 +/- 4% (M +/- m) of the examined patients.

[Characteristics of immunologic homeostasis in the late period after reconstructive operations on the heart valves].

The immune status, i.e. T and B lymphocytes and their populations, was assessed after heart valve replacement or reconstruction in 70 patients with acquired heart defects.

[Sanatorium-resort treatment in a low-mountain region of patients with ischemic heart disease after aortocoronary bypass].

Sanatorium treatment of patients with coronary heart disease performed in Kislovodsk 6-8 months after aortocoronary bypass leads to a substantial improvement of the functional status of patients without anginal episodes and with Functional Classes I and II angina pectoris.

New cardiac bioprostheses: theory, experiments, and 10 years of clinical use.

The biological valve "BAKS" has the following specific features: (1) it is practically devoid of immunogenicity due to fermentative-chemical treatment; (2) it is completely treated with glutaraldehyde through gradual soaking in solutions of increasing concentration; (3) the biological part is fashioned taking into account the biomechanics of the aortic root; (4) the polypropylene stent is functional due to the use of the principles of bionics in valve construction; and (5) practically no thromboemboli occur, because of the special morphologic organization of the cuff and the distant location of the bioprosthesis leaflets from the stent edge. In the Department of Heart Surgery of the National Research Center of Surgery, "BAKS" valves have been used in 237 patients undergoing isolated mitral valve replacement for rheumatic heart disease. Of these 35% were younger than 35 years, 93.
