Oxidized LDL induces ventricular myocyte damage and abnormal electrical activity?role of lipid hydroperoxides

Abstract

Ox-LDL induced cell damage and irregular electrical activity in ventricular myocytes. These effects were dependent on the lipid hydroperoxide content of ox-LDL and were similar to oxidative stress (OS) induced by various OS-generating systems. The observed effects may play a role for functional cardiac abnormalities in patients with increased ox-LDL levels.
