Here's the conclusion of one study published in Atherosclerosis [2007 Jan;190(1):224-31]: Coronary artery calcium score can identify individuals at increased risk for coronary heart disease events who otherwise would be considered low-risk based on clinical assessment. A coronary artery calcium score of zero is associated with very low risk for coronary heart disease in the short to intermediate term ( approximately 3.5 years) regardless of the number of risk factors present.
The mainstream hypothesis that LDL cholesterol drives atherosclerosis may have been falsified by non-invasive imaging of coronary artery plaque burden and progression -- this is the title of an excellent article published in 2009. In above study, 19 studies were cited which seem to falsify the hypothesis that LDL-C is the driving force behind atherosclerosis. The results of these studies were based on direct observation of coronary plaques (both calcified & non-calcified) by Electron Beam CT or Multidetector CT in large numbers of individuals of both sexes, over a wide range of age, ethnic background & cholesterol levels. Therefore, they cannot be easily dismissed.
