From my understanding there are ways to slow plaque progression through diet, supplements, exercise. Plaque can increase as much as 40% per year and keeping progression to a minimal will lower the chances of an event. The only way to do this is through a CAC retest, radiation exposure is minimal. Although high CAC Score means risk is increased, there are probably many other factors involved in having an actual event. Lowering stress, meditation, mindfulness are probably all beneficial. I want to monitor my plaque progression percentage, so I plan to retest after a two year period.
