The Claim
Pericoronary fat inflammation, as measured by the FAI Score, is elevated in patients with atrial fibrillation independent of the severity of coronary artery stenosis and coronary calcium burden.
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.
Patients with atrial fibrillation have higher levels of inflammation around the heart arteries, measured by the FAI Score, even when their artery blockages and calcium buildup are similar to those without atrial fibrillation.
See the scientific wording
Pericoronary fat inflammation, measured by the FAI Score, is elevated in patients with atrial fibrillation independently of coronary artery stenosis severity and coronary calcium burden, suggesting that inflammation may be a distinct pathological feature in AF beyond traditional atherosclerosis.
Inflammation around the heart's main arteries changes the fat tissue there, making it swell with fluid and lose fat. This inflamed fat releases chemicals that spread directly to the left side of the heart, causing scarring and electrical chaos in the heart's upper chamber, which triggers irregular heartbeats.
What the research says
1 studyPeople with atrial fibrillation have more inflammation around their heart arteries than those without it—even when their arteries aren’t more clogged or calcified—suggesting this inflammation is its own problem, not just a side effect of artery disease.
