A Routine Chest CT Scan Could Predict Your Heart Attack…

A Routine Chest CT Scan Could Predict Your Heart Attack Risk, No Extra Test Needed Coronary artery calcium scoring is a well established, powerful predictor of future heart disease. The problem is that measuring it properly has traditionally required a specialised, ECG gated CT scan, a dedicated test that's often not covered by insurance and remains significantly underused in practice. A major new study published in Circulation asks a genuinely practical question, could the far more common, routine chest CT scan, the kind ordered for entirely unrelated reasons, work just as well? Roughly 19 million standard, non gated chest CT scans are performed annually in the United States, compared to just 1.5 million dedicated gated calcium scoring scans. These standard scans are typically ordered for reasons unrelated to heart disease, checking for lung issues, for example, yet they often incidentally capture calcium buildup in coronary arteries. The question researchers wanted to answer, does this incidental information carry the same predictive power as a purpose built cardiac scan. Using data from the well established Multi Ethnic Study of Atherosclerosis, researchers analysed 2,472 participants who underwent both a specialised gated calcium scan and a standard
