Particularities of rhythm and conduction disorders in heart failure patients with preserved ejection fraction admitted to a rehabilitation hospital

Abstract

Background: The mortality and prognosis of patients with heart failure with preserved ejection fraction have shown minimal improvement over the past 20 years, possibly since this condition is often accompanied by various other cardiovascular risk factors and comorbidities, the correlation with various rhythm and conduction disorders being yet to be elucidated. (2) Methods: This study investigated 134 patients with heart failure with preserved and reduced ejection fraction, analyzing the presence and clinical impact of rhythm and conduction disorders in this groups of patients.; (3) Results: Atrial fibrillation is the most common arrhythmia in patients with heart failure with preserved ejection fraction and rhythm and conduction disturbances are significantly associated with essen-tial hypertension (p = 0,005) and chronic pulmonary heart disease (p = 0,016) in this pa-tients; (4) Conclusions: heart failure with preserved ejection fraction is an intensely ar-rhythmogenic condition that requires optimal treatment strategies which are adapted to the multiple possibly associated comorbidities.
