Prevalence of the Frank's sign by aetiopathogenic stroke subtype: A prospective analysis.

ABSTRACT:

Background and purpose

The Frank's sign is a diagonal earlobe crease running from the tragus to the edge of the auricle at an angle of 45°. Many studies have associated this sign with coronary artery disease and some with cerebrovascular disease. The objective of this study was to analyse the prevalence of the Frank's sign in patients suffering from acute stroke with a particular focus on its prevalence in each of the five aetiopathogenic stroke subtypes. Special interest is given to embolic stroke of undetermined source (ESUS), correlating the sign with clinical and radiological markers that support an underlying causal profile in this subgroup.

Methods

Cross-sectional descriptive study including 124 patients admitted consecutively to a stroke unit after suffering an acute
