When considering heart disease warning signs, most people think of chest pain or breathlessness. However, a subtle indicator known as Frank’s sign—a diagonal crease on the earlobe—has been linked to cardiovascular issues. First noted by Dr. Sanders T. Frank, this crease may signal underlying problems with blood vessels and heart health. Research has associated Frank’s sign with conditions such as coronary artery disease, peripheral vascular disease, and high blood pressure. While not everyone with this crease will develop heart issues, it may carry more significance when combined with traditional risk factors like smoking, high cholesterol, and obesity. Experts suggest that the depth and presence of the crease on both ears could influence its relevance to heart health. If you notice a diagonal crease and have other risk factors, consulting a healthcare professional is advisable. Early detection through assessments like blood pressure checks and cholesterol testing can help mitigate the risk of serious heart-related events.
