Dynamics of mechanical dyssynchrony in patients with superresponse to cardiac resynchronisation therapy with a long-term follow-up

Aim. The aim is to assess clinical features of organism and morpho-functional properties of heart and to study the dynamics of mechanical dyssynchrony in patients with congestive heart failure and superresponse to cardiac resynchronization therapy. Material and Methods. 72 patients were examined (mean age 54.3±8.9 years) at baseline and during follow-up visits: 10.5±3.7 months, 52.0±21.4 months. Patients were divided into groups: I group (n=31) with decrease of left ventricle endsystolic volume.30% (superresponders) and II group (n=41) - decrease of left ventricle endsystolic volume
