A Novel Index of Assessing Atherosclerosis Regression and Plaque Stabilization

詳細技術說明

UC San Diego researchers have invented a novel index of atherosclerosis regression that is determined by measuring the plasma content of oxidized phospholipids. The index could provide valuable information to physicians who would use this index to measure the efficacy of treatment with statins or new anti-atherogenic drugs.

*Abstract

Oxidized phospholipids (OxPL) are present in vessel walls and have been shown to be pro-inflammatory and pro-atherogenic. When cholesterol is lowered by drugs or diet, the plasma levels of the OxPL increase, suggesting a movement or clearance of the phospholipids from the vessel wall into the circulation. This activity, then, is an important indicator that plaque stabilization and/or reduction is occurring. Currently, there are no plasma biomarkers that reflect the amount of plaque or determine the benefits of anti-atherosclerotic therapies.

Title: Methods for assessing atherogenesis by determining oxidized phospholipid to apolipoprotein B ratios
Usefulness: Methods for assessing atherogenesis by determining oxidized phospholipid to apolipoprotein B ratios
Summary: The method is useful for determining whether therapy is effective for treating coronary artery disease (claimed).
Novelty: Determining whether therapy is effective for treating coronary artery disease, by determining oxidized phospholipid and apoB levels in samples obtained before and after administration of therapy, and calculating atherogenesis index
