Efficacy and determinants of coronary artery calcium scoring

Overview

Recent medical research and clinical guidelines have evaluated the efficacy of coronary artery calcium (CAC) scoring compared to traditional cardiovascular risk assessment methods.

The CorCal Outcomes trial, involving 5,772 participants in the United States and presented at the European Society of Cardiology Congress, found no significant difference in major cardiovascular events between patients using CAC scores and those using traditional pooled cohort equation assessments, with both groups showing a 2.7% event rate. This imaging approach allows doctors to identify atherosclerosis directly rather than relying solely on traditional risk factors like blood pressure, smoking, or diabetes. Consequently, the 2026 American College of Cardiology and American Heart Association guidelines recommend selective use of calcium scoring for adults with an estimated 10-year risk between 3% and 10%.

Supporting these findings, a Northwestern Medicine study published in JAMA involving over 6,000 adults indicated that while CAC scans offer modest improvement for the general population, they are notably more effective for individuals in the “borderline” or “intermediate” risk categories (3% to 9% estimated risk). Dr. Nilay Shah noted that for these specific individuals, the scan can help clarify whether actual risk deviates from initial estimates based on age, sex, cholesterol, and blood pressure. This research suggests that when used alongside the American Heart Association’s PREVENT risk calculator, the scans add little value for those already classified as low or high risk.

Additionally, research published in Nature Communications from Northwestern Medicine has linked social determinants of health to cardiovascular outcomes. The study found that young adults living in neighborhoods with difficult social conditions—such as high crime rates, financial stress, and limited access to healthy food—were more likely to develop coronary artery calcium buildup later in life.
