Frank's Sign: A Clinical Predictor of Ischaemic Strokes

Area of Science:

• Cardiology
• Neurology
• Clinical Medicine

Background:

• Frank's sign, characterized by a diagonal earlobe crease, has been previously associated with cardiovascular disease.
• Identifying novel, non-invasive markers for cardiovascular risk is crucial for early intervention.

Purpose of the Study:

• To prospectively assess the association between the presence of Frank's sign and the occurrence of ischaemic strokes.
• To determine if Frank's sign can serve as an independent predictor of ischaemic stroke.

Main Methods:

• Prospective observational study conducted over three months in a UK hospital.
• Inclusion of 137 consecutive patients admitted to stroke and elderly care wards.
• Physical examination for Frank's sign and analysis of demographic and medical history data, with statistical analysis using the chi-squared test.

Main Results:

• A significant association was found between the presence of Frank's sign and ischaemic strokes.
• This association remained significant even after excluding patients with pre-existing cardiovascular disease.
• The chi-squared test confirmed the statistical significance of the observed relationship.

Conclusions:

• Frank's sign may represent a valuable clinical predictor for ischaemic stroke.
• Healthcare providers can utilize this easily identifiable sign to identify at-risk individuals.
• Further research is warranted to explore the underlying mechanisms and refine the predictive utility of Frank's sign in stroke risk assessment.
