Bill Blanchet MD interview will be very encouraging. He claims the reason we heard CAC scores only progress is that they were trying to manage results with statins. With his protocol, about third CAC scores regress and a third stay the same.
His views on aspirin, Vit D, Fish Oil and the other recent studies that claimed little efficacy well worth a listen for anyone.
