The aim of the study was to of ventricular remodeling in patients with chronic heart failure (CHF) I-III functional class (FC). In patients with CHF left ventricular remodeling leads not only to re-structure of left ventricular (LV) which accompanied by dilatation and thinning of the cavity, reducing myocardial contractility, but also to changes of geometric shapes of left ventricular and to diastolic dysfunction of LV with domination of the disturbance of relaxation.
