STUDY OBJECTIVE To evaluate the efficacy and tolerability of lovastatin under controlled conditions in heterozygous familial hypercholesterolemia. DESIGN Randomized, double-blind, placebo-controlled, multicenter trial. SETTING Five lipid clinics with a central laboratory and coordinating center. PATIENTS 101 adult patients with heterozygous familial(More)
Angiotensin-converting enzyme inhibitors improve endothelial function, inhibit experimental atherogenesis, and decrease ischemic events. The Quinapril Ischemic Event Trial was designed to test the hypothesis that quinapril 20 mg/day would reduce ischemic events (the occurrence of cardiac death, resuscitated cardiac arrest, nonfatal myocardial infarction,(More)
A high-resolution method of spectral analysis, of the class generally called "maximum entropy method," was used in a study of aortic porcine valve closing sounds in 37 patients (ages 19 to 76). Spectra from 27 normal xenografts, implanted from 2 weeks to 61 months previously, were characterized by a dominant frequency peak, F1, at 89 +/- 15 Hz (mean +/-(More)
We have evaluated the efficacy of plant sterol preparations from two different sources and in two different physical forms in lowering the plasma cholesterol of a total of 46 patients with type II hyperlipoproteinemia when given in addition to appropriate diet therapy. In addition, the mechanisms of the hypocholesterolemic effect were investigated in 7(More)
BACKGROUND Lesion composition, rather than size or volume, determines whether an atherosclerotic plaque will progress, regress, or rupture, but current techniques cannot provide precise quantitative information about lesion composition. We have developed a technique to assess the pathological state of human coronary artery samples by quantifying their(More)
The feasibility of localizing human atherosclerotic plaques by gamma scintillation camera external imaging with technetium-99m-labeled low density lipoproteins (99mTc-LDL) was tested in 17 patients who had atherosclerosis. Imaging demonstrated focal accumulation of radiolabel consistent with 99mTc-LDL sequestration by plaques in the carotid, iliac, or(More)
CONTEXT Little is known regarding carotid intimal medial thickness (IMT) in HIV-infected women and the risk factors for subclinical atherosclerosis in this population, including antiretroviral therapy and the metabolic syndrome. OBJECTIVE Our objective was to assess carotid IMT in relationship to HIV status and antiretroviral therapy in HIV-infected women(More)
