Recent analysis of the World Health Organization International Clinical Trials Registry showed that of 251 trials investigating heart failure treatments, a quarter excluded patients via an upper age limit, and 43% had at least one poorly justified exclusion criterion.1
An analysis of a large cohort of Medicare beneficiaries with heart failure—disease in which 80% of patients are older than 65 years old—reported that only a paltry 18%, 13%, and 25% of those over 65 met the enrolment criteria for the landmark SOLVD, MERIT-HF, and RALES trials. The analysis proposed convenience and study efficiency as possible reasons.2
We have known for years that older people are systematically …
