The presence of a fold in the earlobe indicates an extremely high risk of developing coronary heart disease. Current research has found that people with folds in their earlobes have a 40% or higher chance of developing coronary heart disease, much higher than those without folds in their ears. This suggests a special genetic constitution, and such patients are extremely prone to hyperlipidemia, while coronary vessels are prone to atherosclerosis, and the chances of acute myocardial infarction are much higher. Therefore, for such people, they should pay more attention to their lifestyle, strictly quit smoking and drinking, and have a low-fat diet to prevent the occurrence of coronary heart disease.
