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.
