Two thousand years ago, the Yellow Emperor's Neijing put forward that "the superior medicine treats the disease before it, the traditional Chinese medicine treats the disease of desire, and the inferior medicine treats the disease already". This scientific thought of "preventing disease before disease, preventing disease from degeneration" is a medical and health mode constantly summarized and improved by ancient Chinese doctors. "Upstream treatment" is a new concept, which was first mentioned in the treatment of atrial fibrillation (AF) in 2010. The purpose is to prevent the occurrence and progression of the disease from the level of pathogenic factors before the occurrence of atrial fibrillation. Time and space change, ancient and modern China and foreign countries coincide in medical decision-making mode.
