Coagulation is blood clotting. Chelation is powerful anti-coagulant. However the main effect is not just anti-coagulant but rather removal or polishing of rough or ulcerated atherosclerotic plaque. The effect of which remarkably reduce the chance of (micro) burst of the plaque that trigger clotting in minutes or hours at the site. Autopsy on patients who died within six to eight hours of Myocardial Infarction showed 75% died of blood clot and those who died after 48 hours almost always (98%) died of blood clot.
