[Interrelationship between functional state of the right ventricle and severity of heart failure in patients with ischemic heart disease and depressed left ventricular function].

Dobutamine Doppler echocardiography was carried out in 56 patients (n=56) with ischemic heart disease and depressed left ventricular function (left ventricular ejection fraction <40%) and chronic heart failure. Clinical signs of heart failure were moderate (NYHA class I-II) in 34 and severe (NYHA class III-IV) in 22 patients. Patients with moderate and severe clinical heart failure had similar degree of left ventricular myocardium impairment however those with severe symptoms had more pronounced right ventricular (RV) dysfunction (greater suppression of global and local RV contractility, greater percentage of irreversibly dysfunctional RV myocardium, lower RV contractile response to dobutamine infusion, more pronounced disturbances of RV diastolic filling).

[Sigmental right ventricular contractile function in patients with ischemic heart disease].

Segmental right ventricular function was assessed by dobutamine stress echocardiography in 101 patients with ischemic heart disease and multiple coronary artery lesions. At rest local wall motion abnormalities were found in 69% of patients. Overall 505 segments of the right ventricle were analyzed (5 per patient).

[Risk factors and methods of prevention of complications in digestive organs after myocardial revascularization in patients with generalized atherosclerosis].

The clinico-hemodynamic and angiographic findings in 66 patients with ischemic heart disease were analysed to identify the risk factors of complications in the digestive system and to determine the methods for their prevention after myocardial revascularization. It was found that complications in the gastrointestinal tract develop after extracorporeal circulation more often in patients with lesions of the visceral branches of the abdominal aorta than in those without them. With purposeful preventive therapy and observance of definite precautions before, during, and after the operation, the incidence of complications in abdominal organs and the organs of the retroperitoneal space reduced to one fourth while the nature of these complications was less aggressive.
