The validity of the diagnosis of heart failure (I50.0-I50.9) in the Danish National Patient Register.

CONCLUSIONS: The HF diagnoses (I50.0-I50.9) in the DNPR should be used with caution if validation is not possible. However, restricting analyses to patients registered with a primary diagnosis of HF or patients discharged from cardiology units may be a useful alternative in population-based studies. FUNDING: none. TRIAL REGISTRATION: not relevant. PMID: 29619925 [PubMed - in process]
