title: Inhibition of platelet aggregation by abnormal high density lipoprotein particles in plasma from patients with hepatic cirrhosis.
abstract: ADP-induced aggregation of normal washed platelets was measured by nephelometry in the presence of plasma high density lipoprotein (HDL) from normal subjects and from 30 patients with hepatic cirrhosis. HDL, at one-eighth of its plasma concentration, inhibited platelet aggregation; the effect of cirrhotic HDL (40% [SD 29%] inhibition) was significantly greater than that of normal HDL (16% [11%]). The mean apolipoprotein E content of cirrhotic HDL was significantly higher than that of normal HDL, and strongly inhibitory HDL contained twice as many apolipoprotein-E-rich particles as weakly inhibitory HDL. Inhibition of platelet aggregation was correlated with the apolipoprotein E content of HDL from patients with cirrhosis.
