The Study
Abstract 4363344: Very High-Risk Coronary Artery Calcium Score Without Excess Epicardial Fat Volume might not be Associated with Significant Obstructive Coronary Artery Disease
This study looked at a small group of people and noticed that those with high calcium in their heart arteries but not much fat around their heart didn't seem to have blocked arteries. But it didn't change anything—it just looked at what was already there—so we can't say the fat caused the blockage or didn't cause it.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
Some people have calcium buildup in their heart arteries, but if their fat around the heart is normal, they might not have dangerous blockages.

Key takeaways
Summary
Based on the study abstract and findings.
- 1This means having high calcium alone doesn't always mean you're at high risk — if your heart fat is normal, your risk may be much lower.
- 2All 55 people with high calcium scores but normal heart fat had no blockages; those with high heart fat had more inflammation and heart problems.

People with more epicardial fat have five times the rate of coronary events compared to those with less epicardial fat.
Among asymptomatic adults with high coronary artery calcium scores, those with normal epicardial fat volume have lower levels of C-reactive protein, a marker of systemic inflammation, regardless of their body weight.
Among adults with high coronary artery calcium scores but no symptoms, those with normal amounts of fat around the heart are less likely to have severe blockages in their coronary arteries, as confirmed by invasive or stress tests.
In people without symptoms of heart disease, having both excess fat around the heart and calcium buildup in the coronary arteries is a stronger predictor of future heart problems than calcium buildup alone.
People with very high calcium buildup in their heart arteries but normal fat around the heart are less likely to have blocked heart arteries than those with both high calcium and high fat around the heart.
People with high levels of fat around the heart and high coronary artery calcium scores show higher levels of systemic inflammation and signs of cardiovascular dysfunction, regardless of their body weight.
