Acta Cardiol. 2021 Oct;76(8):878-886. doi: 10.1080/00015385.2020.1797303. Epub 2020 Aug 19. PMID: 32812491.Abstract
Background: Relationship between the frequency of occurrence of bendopnea during the daily life of heart failure (HF) outpatients and clinical outcomes has never been evaluated before.
Methods: Turkish Research Team-Heart Failure (TREAT-HF) is a network between HF centres, which undertakes multicentric observational studies in HF. Herein, the data including stable 573 HF patients with reduced ejection fraction out of seven HF centres were presented. A questionnaire was filled by the patients, with the question 'Do you experience shortness of breath while tying your shoelace?', assessing the presence and frequency of bendopnea.
Results: To the question related to bendopnea, 48% of the patients answered 'yes, every time', 31% answered 'yes, sometimes', and 21% answered 'No'. Patients were followed for an average of 24 ± 14 months, and the patients who answered 'yes, every time' and 'yes, sometimes' to the bendopnea question were found having increased risk for both HF-related hospitalisations (HR:3.2, p < .001- HR:2.8, p = .005) and composite outcome consisting of 'HF-related hospitalisations and all-cause death in the multi-variate analysis (HR:3.1, p < .001- HR:3.0, p < .001). Kaplan Meier analysis for HF-related hospitalisation, all-cause death, and the composite of these were provided for these three groups, yielding significant and graded divergence curves with the best prognosis in 'no' group, with the moderate prognosis in 'sometimes' group, and with the worst prognosis in the 'every time' group.
Conclusion: For the first time in the literature, our study shows that the increased frequency of bendopnea occurrence in daily life is associated with poor outcomes in HF outpatients.
