Episode 960: Frank's Sign - A Marker for Coronary Artery Disease

Contributor: Travis Barlock MD
Educational Pearls

  • Frank's sign is a curious physical exam finding first described in the literature in 1973
    • Bilateral earlobe creases are recognized as a marker of coronary artery disease and cerebrovascular disease
  • Some studies have found an increase in all-cause mortality in patients with bilateral diagonal earlobe creases
  • The pathophysiology is still not fully understood
    • One 2020 study found histopathological changes associated with diagonal earlobe creases, potentially linking them via a model of hypoxia/reoxygenation
