Abstract: OBJECTIVE: The aim of this study was to evaluate characteristics of patients with heart failure (HF) with preserved ejection fraction (HFPEF) and to assess prognostic predictors in 2-year follow-up. Preserved right ventricular systolic function (PRV) was defined as the peak systolic tricuspid annular velocity (S’) >10.8 cm/s. RESULTS: HFPEF and HFREF patients had non-significantly different 2-year all-cause and CV mortality (28.6 % vs 37.0 %, 17.5 % vs 21.7 %). Patients with HFPEF and PRV vs dysfunctional RV had a better survival (76.6 % vs 56.3 %, p=0.045). In HFPEF, the patients who survived had a trend to better S’ (13.6±3.1 cm/s vs 11.9±3.4 cm/s, p=0.055), shorter QTc (427±42ms vs 454±42ms, p=0.058), and all-cause mortality was lowered only by anticoagulants (12.0 % vs 39.5 %, p=0.02). QTc interval and PRV emerged as predictors of all-cause mortality (HR 1.7 per 40 ms change, 95 % CI 1.1–2.6, p = 0.02, HR 0.38, 95 % CI 0.15–0.93, p=0.03). |
