To evaluate the association of lipoprotein(a) [Lp(a)] level with short- and long-term outcomes after coronary artery bypass grafting (CABG) and to assess the effect of a 12 month course of weekly lipoprotein apheresis on vein graft patency and coronary atherosclerosis course in post-CABG patients with hyperlipidemia.
Living parents of group A had a higher prevalence of arterial hypertension (42 vs 14% p < 0.01) and hyperlipidaemia (49 vs 26% p < 0.05) as well as higher levels of lipoprotein (a) [median (range) 27.2 (1-107) vs 15.6 (0.2-98) mg/dl; p < 0.05].
Several family members had hyperlipidemia and early onset of ischemic heart disease not due to the 10 bp deletion, and several family members had unexpectedly high serum lipoprotein(a) contributing to high concentrations of serum LDL cholesterol.
In hyperlipidemia and, in particular, elevated lipoprotein (a) [Lp(a)] levels there appears to be pronounced linkage between the development and progression of atherosclerosis.
