Abstract: Acute myocardial infarction (AMI), the leading cause of cardiovascular disease morbidity and mortality worldwide, is caused by a sharp reduction or interruption of coronary blood supply, resulting in vascular necrosis of the affected myocardium and the inflammatory response plays an important role in the process of AMI. In recent years, studies have found that in addition to early white blood cells and their differential count, the ratio of some peripheral blood cells has good application value in risk stratification and prognosis assessment of AMI patients. This article reviews the research progress of various peripheral blood count indexes in the prediction of AMI-related diseases in recent years.
