Coronary Calcium Scores Highly Effective in Identifying Heart Disease Without Known Risk Factors

Findings from the study were presented at the American Heart Association’s Scientific Sessions 2023 in Philadelphia on Nov 11, 2023.

In the study, Intermountain researchers identified 429 heart attack patients who also had coronary artery calcium scans. Of those, 369 had standard modifiable risk factors (SMuRF), like a diagnosis or treatment of hypertension, hyperlipidemia, diabetes, and or smoking; and 60 did not (SMuRF-less).


Researchers examined these patients’ calcium artery scan scores, and then also major adverse cardiovascular events, like another heart attack, stroke, or death, at 60-days and long term.

Researchers found that SMuRF-less patients had high rates of, and higher percentile of, coronary calcium scores. They also found that 77% of these patients met their criteria for preventative therapy, like statins and/or aspirin. Patients with SMuRF, as expected, also had high CAC scores and percentiles. Outcomes were more favorable overall for SMuRF-less patients and for those patients with lower coronary artery calcium scores.

“We’re missing about a quarter of people who are at risk for heart attack events because we’re still relying on just the standard risk factors,” said Dr. Anderson. “We haven’t been doing scans in low-risk patients that don’t have these common risk factors, but that may need to change given our findings, so that we can identify these seemingly low-risk patients who care not, and provide preventive therapy.”
