To the Editor The US population is aging rapidly; geriatric and age-related physiological syndromes predispose older patients to significant complexity in disease management. In recent years, attention to frailty and multisystem dysregulation has increased substantially in the medical and surgical literature. Interest in frailty among cardiovascular disease investigators has flourished, yet controversy exists regarding the ascertainment of frailty syndrome among older patients. The tools to assess frailty are numerous, and some of these tools may result in misclassification of frailty status in some patients.1
