Low-density lipoprotein (LDL)cholesterol is usually described as the "bad cholesterol" because high levels are associated with an increased risk of acute coronary syndrome (ACS),stroke,and peripheral arterial disease (PAD).High LDL levels initiate the atherosclerotic process by infiltrating the vessel wall and binding to the matrix of cells beneath the endothelium.Total cholesterol levels below 200 are considered normal.High-density lipoprotein (HDL)cholesterol levels below 40 are at low risk of coronary artery disease.Triglyceride levels below 150 are considered normal.
