5 - Current and emerging therapies in atheroprotection



The global epidemic of cardiovascular disease (CVD) continues to rise, with atherosclerotic CVD remaining the lead cause of morbidity and mortality worldwide, comprising of 29% of all global deaths in 2003. A majority of these deaths were directly caused by coronary artery disease (CAD) or strokes. It is estimated that up to 50% of all deaths and disability due to CAD and strokes could be curtailed by a number of lifestyle and therapeutic approaches that directly target major cardiovascular risk factors.

Atherosclerosis is a systemic disease process involving multiple vascular territories. The presence of established vascular disease, regardless of the territory involved, portends the greatest risk of incident cardiovascular events. The prevalence of asymptomatic coronary stenoses of greater than 50% angiographic severity in non-disabling ischaemic stroke patients has recently been estimated to be 20%, and those patients afflicted with peripheral arterial disease have a probability of death due to CAD and stroke of 55% and 11% respectively. Given the significant systemic plaque burden in these patients coupled with corresponding high event rates, various anti-atherosclerotic and vascular protective therapies have the potential to significantly lower absolute clinical event rates.


Atherosclerosis is a chronic inflammatory condition, characterised by the accumulation of inflammatory cells, lipid and apoptotic material within the arterial wall. The endothelial cell layer, a single cell layer lining the lumen of the vasculature, serves to regulate permeability of the arterial wall, vascular tone and tendency for thrombus formation.
