Assessment of bleeding disorders in Sheehan's syndrome: are bleeding disorders the underlying cause of Sheehan's syndrome?

abstract：:Platelets play a key role in thrombotic vascular occlusion at the side of an atherosclerotic plaque. Malondialdehyde (MDA) derivatives are components of oxidized LDL. Recent studies suggest enhanced adhesion of platelets on oxidized LDL, but evidence of MDA-modified LDL contribution to enhanced platelet adhesion is mi...
