[Peculiarities of systolic and diastolic function of left and right ventricles in elderly and geriatric patients with stable effort class II-III angina during formation of chronic heart failure].
In order to reveal peculiarities of function of cardiac ventricles in functional class (FC) II-III chronic heart failure (CHF) Doppler echocardiography (DE) and myocardial tissue Doppler echocardiography (TDE) were carried out in 108 middle aged, elderly and old patients. Patients with signs of FCIII CHF had pronounced impairment of global contractile function of left and right ventricles (LV and RV) with RV ejection fraction (EF) higher than LV EF. These patients had lower parameters of central hemodynamics, high parameters of pulmonary hypertension, increased thickness of RV free wall, greater percentage of irreversible LV and RV myocardium in response to deep breath, more pronounced derangements of RV and LV diastolic filling. In patients with FC II of CHF and moderate RV dysfunction its pump function is determined by degree of impairment of systolic function, diastolic filling, while in patients with FC III of CHF and pronounced dysfunction of RV myocardium its pump function is to a lesser degree determined by ventricular contractile function, but becomes dependent on diastolic filling of RV and the state of LV.
