Kinetics of LDL subfractions.

abstract：:This article reviews the evidence that congestive heart failure is accompanied by an increased plasma norepinephrine concentration and that this is due not only to a reduced tissue clearance of the substance but also to a marked increase in sympathetic nerve activity. It also reports data that indicate that the sympat...
