To the Editor Dr Pokorney and colleagues1 described low (8.1%) use of implantable cardioverter-defibrillators (ICDs) in older patients with myocardial infarction (MI) who met criteria for implantation. They inferred that many older patients with MI not referred for ICDs might have benefited with significant prolongation of life. They also suggested that modifiable system factors contribute to ICD underuse.
