SHARE-FI (Frailty Index in Elderly Cardiac) Calculator

SHARE-FI (Frailty Index in Elderly Cardiac Patients): Explanation and Clinical Context SHARE-FI is a validated tool designed to assess frailty in community-dwelling older adults, particularly useful in elderly cardiac patients. It uses five domains: exhaustion, loss of appetite, weakness (grip strength), slowness (walking speed), and low physical activity. Each domain contributes to a composite score that classifies patients as non-frail, pre-frail, or frail.

Frailty in cardiac patients has been associated with increased risk of hospitalization, mortality, and poorer outcomes after interventions. This tool helps clinicians stratify risk, optimize pre- and post-procedural care, and guide shared decision-making.
