The Claim
In asymptomatic middle-aged adults in the United States who are classified as having low cardiovascular risk based on traditional assessment methods, 31.5% have evidence of subclinical coronary plaque and 18.3% have noncalcified plaque, with 76.7% of these individuals having a coronary artery calcium (CAC) score of zero, suggesting that traditional risk assessment may fail to detect early-stage atherosclerosis.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Even if middle-aged Americans seem healthy and have low heart disease risk, over 30% still have hidden plaque in their arteries — and most of them have a heart scan score of zero, meaning standard checkups might miss early warning signs.

In asymptomatic middle-aged U.S. adults classified as low cardiovascular risk, 31.5% have subclinical coronary plaque and 18.3% have noncalcified plaque despite 76.7% having a coronary artery calcium (CAC) score of zero, indicating that traditional risk assessment may miss early atherosclerosis.
What the research says
1 studyThe study found that many people with low heart disease risk and normal calcium scores still had hidden heart artery plaque, just like the claim says.
