AIM: The aim was to evaluate clinical, morphological, functional features and mortality in patients with congestive heart failure (CHF) and different time of the best response to cardiac resynchronization therapy (CRT).
MATERIALS AND METHODS: 122 patients (82.8% men) with NYHA functional class III-IV (mean age 54.8 ± 9.6 years) were enrolled. At baseline, 1, 3 months and each 6 months after implantation we evaluated clinical and echocardiographic parameters. In 28 patients the best decrease of left ventricular end-systolic volume (LVESV) was achieved up to 3 months (1.1 ± 0.9 months, I group–early response) and in 94 patients–after 3 months (22.6 ± 14.9 months, II group–late response).
