Framingham and the Muddy Waters- Jeffrey Gerber, MD 

Thank you for posting the presentation. I've enjoyed Dr Gerber and Mr Cummin's book Eat Rich Long Long, and I've heard Ivor repeat that a high calcium score (in CT CAC scan) while it appears to predict risk, is less predictive if no further increase (or if the rate of increase is low). That a high calcium score at a single point in time can be a high risk, while that same-or only slightly higher-score at some later time has a reduced risk, is confusing. Unless we have an earlier point of reference, there's no way of knowing whether that first score was the same-or only slightly higher than-five years prior. Therefore, according to your findings, either 1) that exact same first score is NOT as high a risk as your chart would indicate, OR 2) the idea that the risk drops over time is faulty. At any rate, there must then be some other factor beside the amount of calcium deposit that makes the risk if the same amount is at one time high risk, and at a later time is low risk. ???
