The Claim
Genetically predicted systolic blood pressure mediates 27% (95% CI: 3% to 50%) of the association between higher body mass index and increased coronary artery disease risk.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Higher body mass index increases coronary artery disease risk, and 27% of this increase is explained by genetically predicted higher blood pressure.
See the scientific wording
Genetically predicted systolic blood pressure mediates 27% (95% CI: 3% to 50%) of the increased coronary artery disease risk from higher BMI, indicating that hypertension is a major, but not dominant, pathway through which obesity contributes to heart disease.
Extra fat tissue releases substances that raise blood pressure, which forces the heart to pump harder and damages the inside of arteries, leading to plaque buildup and heart disease.
What the research says
1 studyThis study found that about one-quarter of why being overweight increases heart disease risk is due to high blood pressure — the rest comes from other factors like diabetes. So controlling blood pressure helps, but it’s not the whole story.
