It is true that ischemic preadaptation, a concept pioneered in the United States in 1986, refers to repeated transient myocardial ischemia that produces a protective effect on the myocardium so that the myocardium develops a high degree of tolerance in the face of prolonged ischemia. Ischemic pre-adaptation refers to the induction of a protective effect on organs other than the ischemic organ against the ischemic-hypoxic condition when some organs of the body are subjected to a transient and reversible ischemic-hypoxic stimulus. Simply put, repeated, harmless ischemic pre-adaptation training for the human body can stimulate the body’s immune system stress function, thereby generating endogenous protective substances, which can protect the myocardium and participate in energy metabolism, to reduce the damage caused by ischemia and hypoxia for a longer period of time in the future, which can effectively avoid the occurrence of cardiovascular and cerebrovascular diseases such as cerebral infarction, myocardial infarction, and so on. Ischemic pre-adaptation is recommended to go to the regular hospital for consultation and conduct. Avoid leading to serious consequences.
