Abstract:
Acute coronary syndrome (ACS) is the syndrome including unstable angina pectoris and
acute myocardial infarction syndrome, and is a common acute disease of cardiovascular
system. ACS is with rapid development and poor prognosis, and can lead to different degrees
of heart function damage, and effective auxiliary examination indexes are needed to early
diagnose disease and predict prognosis. Red cell distribution width (RDW) is the index used
to measure red blood cell volume variation and dispersion degree. In recent years, studies
have confirmed that RDW has predicting effect on the risk of cardiovascular events and
prognosis, and the risk of coronary disease is larger in population with higher RDW
