studies indicate that lipid-lowering improves endothelial function. Current National
Cholesterol Education Program (NCEP) Adult Treatment Panel II guidelines consider
desirable low-density lipoprotein (LDL) cholesterol levels in patients with coronary
artery disease (CAD) to be ≤100 mg/dl,
8
although recent trials using statin lipid-lowering treatment in patients with CAD
have suggested there is no longitudinal benefit of lipid lowering among patients with
baseline LDL cholesterol <125 mg/dl.

Although coronary angiographic trials suggest that more intensive intervention (i.e.,
LDL cholesterol <100 mg/dl) is associated with improved results in terms of the regression
or arrest of progression of coronary lesions compared with more moderate LDL cholesterol
reduction,
11
no trial has directly assessed whether there is mortality benefit from lowering LDL
cholesterol levels to the NCEP goal of 100 mg/dl. To determine whether achievement
of the current NCEP cholesterol recommendations are consistent with beneficial endothelium-dependent
vasodilatation, we assessed endothelium-dependent brachial artery vasoreactivity noninvasively
in stable CAD patients. We hypothesized that achievement of LDL cholesterol ≤100 mg/dl
would be associated with more beneficial endothelial vasoreactivity than LDL cholesterol
>100 mg/dl in patients with CAD.To read this article in full you will need to make a payment
