Sudden Cardiac Arrest Survivorship: A Scientific Statement From the American Heart Association.

abstract：BACKGROUND:Although long-term lipid-lowering therapy improves endothelium-dependent vasodilatation in humans, it remains unknown whether the short-term removal of LDL per se ameliorates endothelial dysfunction. METHODS AND RESULTS:To examine the effects of a single session of LDL apheresis on endothelial function in p...
