Effects of lipid lowering therapy on progression of coronary and carotid artery disease.
Review
Overview
abstract
Recent data have extended the benefit of lipid lowering therapy to patients with only mildly to moderately elevated LDL-cholesterol, which is typical of patients with coronary artery disease. Meta-analysis of clinical trials of statin therapy with similar sample sizes indicated that the LDL-cholesterol level on treatment was as good a predictor of angiographic benefit as was the percentage reduction in LDL-cholesterol. We review evidence that management of triglyceride-rich lipoproteins, HDL, fibrinogen, lipoprotein particle size, LDL-oxidation, and lipoprotein (a) may also favorably influence atherosclerotic progression. Angiographic and arterial ultrasound trials of lipid lowering therapy have demonstrated benefits on disease progression that are consistent with benefits on myocardial infarction, stroke, and death reported in larger, lengthier trials.
