62yo Male 5yrs Post Cardiac Arrest, 90% Occlusion Of One

62yo male 5yrs post cardiac arrest, 90% occlusion of one of the cardiac arteries. So, the plaque that built up through bio-chemical/physical alchemy over multiple years, i.e. eating habits, snacking habits, working habits, exercise habits...in the end...biochemistry....all biochemistry...energy in and out...nano particles, macro particles all interacting. Q: If this chemical equation went in one direction, how does one reverse the equation...naturally. How do I get rid of arterial/vascular plaque, and how long to completely reverse...like smokers can reverse the (some/most) effects of smoking on their lungs and other body systems....how do we cleanse completely the vascular/neuronal/brain system of "plaque". Try your best to answer the question through chemistry and nutritional science...don't pass me/this of to big pharma. Please. I don't like their "alchemical magic" outcomes. People of the light can do better...eh?
