详细描述
Acute coronary syndrome (ACS) refers to a group of conditions that include ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI), and unstable angina. It is a type of coronary heart disease (CHD), ACS is the most common cause of death in patients with CAD and it is estimated that about 661,000 people in the United States suffer from ACS in 2016 ,which highlights the importance of risk assessment for ACS.
Elevated remnant cholesterol, including cholesterol carried in VLDL and chylomicron remnants, is emerging as a causal risk factor for ASCV in addition to elevated LDL-cholesterol ,Studies of the general population have shown that risk of myocardial infarction, ischemic stroke and peripheral artery disease is increased in individuals with elevated remnant cholesterol. High-density lipoprotein-cholesterol (HDL-C) exhibits anti-atherosclerotic effects by neutralizing the pro-inflammatory and pro-oxidant effects of monocytes via inhibiting the migration of macrophages and LDL oxidation in addition to the efflux of cholesterol from these cells. Furthermore, HDL plays a role in suppressing the activation of monocytes and proliferation-differentiation of monocyte progenitor cells. Thus, accumulation of monocytes and reduction of HDL-C may participate in atherosclerosis and cardiovascular diseases (CVD) .
Global Registry of Acute Coronary Events (GRACE) score is a risk assessment system for ACS based on risk factors summarized from clinical cases.
The Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score is a scoring system for risk stratification based on the anatomical characteristics of coronary artery lesions to help cardiologists, interventionists and surgeons to grade the complexity of coronary artery lesions .
