The Claim
Patients with atrial fibrillation have significantly higher pericoronary fat inflammation, as measured by the FAI Score, than patients without atrial fibrillation, particularly around the left anterior descending artery, in the context of coronary artery disease.
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.
In people with coronary artery disease, those who have atrial fibrillation show higher levels of fat inflammation around the left anterior descending coronary artery compared to those without atrial fibrillation, as measured by the FAI Score.
See the scientific wording
Patients with atrial fibrillation exhibit significantly higher pericoronary fat inflammation, as measured by the FAI Score, compared to those without atrial fibrillation, particularly around the left anterior descending artery, suggesting a regional association between coronary perivascular inflammation and atrial fibrillation in individuals with coronary artery disease.
Inflammation around the main artery on the left side of the heart causes fat tissue there to swell and release chemicals that spread to the nearby upper heart chamber. This makes the tissue stiff and disrupts its electrical signals, leading to irregular heartbeats.
What the research says
1 studyPeople with a heart rhythm problem called atrial fibrillation have more inflammation in the fat around their main heart artery than those without it—even when their artery blockages are similar. This suggests the inflammation near the heart might be linked to the rhythm problem.
