Figure 6 Percentage of coronary artery disease (CAD) patients with either previous myocardial infarction, prior bypass surgery or a percutaneous coronary intervention who had a low-density lipoprotein (LDL) cholesterol level 130 mg/dl. Note that even the 90th percentile of performance in this survey yielded only 64.4% of patients achieving an LDL cholesterol of 130 mg/dl. In actuality, the National Cholesterol Education Program guidelines indicated that such patients with documented CAD need to have their LDL cholesterol levels lowered to <100 mg/dl.
