Authors' conclusion

This study highlights the value of routine comorbidity screening in HFpEF, identifying one new comorbidity per patient on top of three pre-existing conditions, most commonly sleep apnoea or iron deficiency. Treatment of existing comorbidities was often suboptimal.

Study context

Population

Participants
501 patients
Outcome
Diagnostic yield of standardized routine workup for comorbidities (laboratory testing, sleep apnoea screening, 24 h Holter, spirometry, exercise testing, 6 min walk test)
