Plaque volume causes less blood to flow through the artery, it's of function of the vessel radius to the 4th power (and the length of the reduced diameter). So small changes in the diameter of the vessel can have large implications to the flow.
Lower flow to muscle walls of the heart causes demand myocardial ischemia, chest pain with exertion.
A drug that can reduce plaque volume is an amazing medical finding, especially considering the side effect profile. It can be used to treat:
1) Peripheral vascular disease and claudication (pain in leg muscles due to decreased blood flow)
2) Cerebrovascular disease caused by atherosclerosis of blood vessels in the brain
3) CAD, atherosclerosis in the heart leading to ischemia. Ischemia in the heart can cause chest pain and fatal cardiac arrhythmia's such as Ventricular Tachycardia or Ventricular Fibrillation
These disease processes are treated by current VERY EXPENSIVE surgical interventions such as:
1) Arterial bypasses and stents in femoral arteries
2) Carotid Endarterectomies & interventional Neurovascular procedures (Huge growing field)
3) Open Heart surgery, CABG's & Interventional stents place in heart arteries
None of this takes in the physiologic effects of reducing inflammation.
EPA does more than reduce plaque growth it reverses it and CHERRY IMO is a HUGE event.
