| Popis: | Aim. Based on clinical parameters and diagnostic investigations, to create a complex model of personalized selection of patients with heart failure (HF) for cardiac resynchronization therapy (CRT). To establish the diagnostic value of the created model in predicting 5-year survival.Material and methods. The study included 141 patients with HF (men, 77,3%; women, 22,7%). The mean age of patients at the time of implantation was 60,0 [53,0; 66,0] years. All patients had New York Heart Association (NYHA) class II-IV HF, left ventricular ejection fraction (LVEF) ≤35%, and QRS ≥130 ms. Patients were randomly divided into training (n=95) and test (n=36) samples, which were comparable in main clinical and functional characteristics.Results. The index included parameters that had a significant relationship with 5-year survival according to the Cox regression: male sex, prior myocardial infarction, hypertension, QRS |
