According to the ATP III guidelines for LDL management, a person with 0-1 risk factors for coronary artery disease (see below) should have an LDL of less than 160 mg/dL. If the LDL is between 160-190, then diet/lifestyle modifications should be initiated. If the LDL is > 190, then medications (HMG-CoA reductase inhibitor or "statin") should be started. Coronary heart disease risks factors include tobacco use, hypertension, low HDL levels, a family history of premature heart disease (male < 55 years old or female < 65 years old), and age (men > 45 and women > 55). An HDL cholesterol of > 60 mg/dL counds as a negative risk factor (cancels out 1 risk factor).
