The Claim
In asymptomatic middle-aged adults with elevated low-density lipoprotein cholesterol (LDL-C) and no coronary artery calcium (CAC = 0), approximately 28% have non-calcified atherosclerotic plaque detected by coronary computed tomography angiography (CCTA), indicating that CAC scoring may fail to identify early atherosclerosis in this high-risk subgroup.
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 a heart scan shows no calcium buildup, nearly 3 in 10 middle-aged people with high 'bad' cholesterol still have soft plaque in their arteries — meaning the usual heart risk test might miss early warning signs.
See the scientific wording
Among asymptomatic middle-aged adults with high LDL-C and no coronary artery calcium (CAC = 0), approximately 28% still have non-calcified plaque detected by CCTA, suggesting that CAC scoring alone may miss early atherosclerotic changes in high-risk individuals.
What the research says
1 studyThe study found that nearly 3 in 10 people with high cholesterol and no calcium in their heart arteries still had soft plaque, which a calcium scan wouldn't catch. This supports the idea that calcium scans alone might miss early heart disease.
