Copenhagen Heart Failure With Preserved Ejection Fraction

The study is a prospective, observational cohort study. Using risk factors for HFpEF, the Danish National Health Registries will be used to identify up to 5000 citizens with at least one risk factor for HFpEF relying on International Classification of Diseases, 10th revision (ICD-10), medication, and biochemistry. The investigators will only recruit patients from the Capital Region of Denmark. Participants will be recruited by sending recruitment letters to a secure electronic mailbox (eBoks) linked to the patients' social security numbers. The purpose of this study is to evaluate the identification and screening procedures for HFpEF outlined in this protocol. Additionally, the investigators aim to gauge the willingness of identified Danish adults with risk factors for HFpEF to participate in the study and to identify and address any barriers to their involvement. Overall, the investigators expect the results of this study can be used to guide future initiatives aimed at improving the identification and enrollment of patients with HFpEF, particularly among vulnerable populations.
