Statin therapy reduces coronary artery disease morbidity and mortality in p
rimary and secondary prevention trials including patients with elevated and
average cholesterol levels. The association between reduction of total or
low-density lipoprotein cholesterol and preventive benefit is well establis
hed, However, additional risk factors for coronary artery disease need to b
e incorporated into risk assessment to provide an accurate measure of globa
l risk for use in lifestyle intervention and drug therapy guidelines. Asses
sment of outcomes in the Air Force/Texas Coronary Atherosclerosis Preventio
n Study primary prevention trial, which involved patients with average chol
esterol levels and reduced high-density lipoprotein cholesterol (HDL-C), su
ggests the importance of on-treatment values of apolipoproteins B and A-I i
n predicting first major events in such a population. Other data, including
trials of fibrate therapy showing reduction in coronary artery disease eve
nts, support the importance of triglycerides and HDL-C in coronary artery d
isease risk. Challenges for future treatment guidelines include incorporati
on of emerging and novel risk factors into risk assessment, refinement of g
lobal risk measurement, and simplification for application to clinical prac
tice. (C) 2001 by Excerpta Medica, Inc.
