From vulnerable plaque to blood healthy therapy.

Cardiovascular atherosclerotic disease is the leading cause of death in China and in Western nations. People with plaque or stenosis in the coronary artery or the carotid artery are the most susceptible population to suffer from acute events. Current investigations showed that plaque with the characteristics of intra-plaque hemorrhage or a thin cap with a large lipid core was causally associated with vulnerable plaque and plaque rupture. Of the many plaque ruptures occurring in patients with atherosclerotic disease, very few will trigger symptomatic events, rendering it exceedingly difficult to predict adverse outcomes. The assumption that identifying lesions prone to rupture will prevent acute coronary events was unrealistic. Factors in blood, especially those risk factors associated with thrombosis, play an important role as a bridge between plaque rupture and subsequent clinical events. Since there is little management to efficiently decrease the frequency of plaque rupture or erosion, blood healthy therapy, as a therapeutic apheresis to decrease the blood hypercoagulability to modulate the blood to be thrombosis resisting, should be considered as a potential therapeutic approach to reducing the incidence of acute coronary syndrome and stroke.
