The so-called "life chain" refers to a series of orderly steps and standardized and effective rescue measures for patients with cardiac arrest. These rescue sequences are connected together in the form of chain X, which constitutes a "survival chain" to save lives. The American College of Cardiology was officially launched, and it was described in the American Medical Journal in June 1992. Modern first aid, especially on-site rescue, is usually described in this way.
Acute coronary syndrome
Acute coronary syndrome (ACS) is a group of clinical syndromes caused by acute myocardial ischemia, including acute myocardial infarction (AMI) and unstable angina pectoris (UA), among which AMI is divided into ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI). Platelet activation plays an important role in the occurrence of ACS.
