Comments on: The Coronary Artery Calcium Score and Stress Myocardial Perfusion Imaging Provide Independent and Complementary Prediction of Cardiac Risk http://www.thepreparedminds.com/archives/474 In the field of observation, chance favors the prepared minds.

In their study, they showed that CAC scoring and SPECT results provide independent and complementary predictors of a patient's cardiovascular disease risk. While a normal SPECT result predicts short-term event-free survival, the presence of a significantly elevated CAC score is associated with greater long-term risk for cardiac adverse events.
