Introduction: Previous studies have shown that hyponatremia is associated with unfavorable prognosis in patients with heart failure (HF). However, only few studies aimed at the evaluation of long-term outcome in hyponatremic patients hospitalized for HF.
Objectives: The aim of this study was to assess clinical characteristics and 1-year outcome of patients hospitalized for HF with hyponatremia at hospital admission.
Background: Resting heart rate (HR) has been proven to influence long-term prognosis in patients with chronic heart failure (HF). The aim of this study was to assess the relationship between resting HR at hospital admission and hospital outcome in patients with HF.
Methods: The study included Polish patients admitted to hospital due to HF who agreed to participate in Heart Failure Pilot Survey of the European Society of Cardiology.
