But there are some less well known physical signs of heart disease risk, which should perhaps become more well known by family members and friends, in order to recommend or persuade those with the risk factors to seek professional help with testing, diagnosis and treatment. The physical sign, that being externally visible, even if the person doesn't feel unhealthy, is called Frank's sign, or diagonal earlobe crease (Więckowski, Gallina, Surdacki & Chyrchel, 2021).
While the earlobe crease is a little known and seldom-used, it is quick and non-invasive and easy to interpret and should be used according to the referenced study and others.
These studies suggest that the earlobe crease is a sign of chronic hypoxia (low oxygen levels), possibly from atherosclerosis (plaques in the major arteries which can reduce blood flow) and low oxygen supply to the cells and tissues.
The referenced study concluded that the diagnostic accuracy of the earlobe crease is comparable to the traditional electrocardiography (ECG) testing in detecting significant coronary stenosis/blockages and hypoxia. It shouldn't be the only test used, but isn't always a clinically accurate indicator in all cases. But it can give big clues to friends and family to look for this sign and recommend (or persuade) those with this sign to get some proactive testing and treatment if needed.
Medical advice and testing is needed for those with the Frank's earlobe crease, but medical advice does not include finding the root causes of the heart disease, but only to temporarily remove the issue with surgery and "manage" it with medications that cause more symptoms, and not about prevention or stopping the issue coming back.
Natural therapies are more focussed on prevention and finding and fixing the root causes in each person. This is where I can help - if you have this earlobe sign, or know someone who does, please see me for testing advice, and also for root cause analysis and proactive preventative advice and treatments.
