Cardiovascular diseases remain the primary cause of death. 1 Myocardial infarction (MI), angina, and stroke take> 16 million lives every year, but the underlying mechanisms by which these often-fatal cardiovascular events occur tend to escape attention. 2 Atherosclerosis is the underlying pathological inflammatory vascular disease not only responsible for most MIs and strokes, but it accounts for 29% of deaths worldwide. 1, 3
Once believed to be a passive process, it is now understood that atherosclerosis takes an active route involving several cell types, with contributions from a multitude of organ systems, molecular mechanisms, and other pathological conditions, including, but not limited to, hypertension, hyperlipidemia, and type 2 diabetes mellitus. 1, 3–5 Atherosclerosis is characterized by the accumulation of lipids, fibrous elements, and inflammatory cells within the vascular wall of medium and large muscular and elastic arteries. 1, 3, 6 Atherosclerotic plaque formation leads to intimal thickening and luminal stenosis. 1 Reduction of blood flow ensues, leading to ischemia of the brain, heart, and extremities and clinically manifesting as MI, angina, or stroke. The main features of atherosclerosis are endothelial dysfunction, intimal thickening, inflammation, and vascular calcification (VC). 4, 7, 8 These processes are considered a consequence to vascular injury. 1 VC is characterized by calcium deposition in the walls of the vasculature. 5 Expansion of the calcified lesion leads to thrombus formation and, if significant enough, vascular occlusion. Although the exact mechanisms for VC are unknown, there has been an increase in interest about the role Wingless (Wnt) signaling plays in
