The Claim
Estimated glucose disposal rate (eGDR), calculated from waist circumference, HbA1c, and hypertension status, is independently associated with heart failure risk in older adults, with each one standard deviation increase in eGDR associated with a 27–30% reduction in heart failure risk after adjustment for multiple confounders.
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 older adults, a higher estimated glucose disposal rate (eGDR), which is calculated from waist size, blood sugar levels, and blood pressure status, is linked to a lower risk of heart failure. Each one standard deviation increase in eGDR corresponds to a 27–30% lower risk of heart failure.
See the scientific wording
Estimated glucose disposal rate (eGDR), a surrogate marker of insulin resistance calculated from waist circumference, HbA1c, and hypertension status, is independently associated with heart failure risk in older adults, with each one standard deviation increase in eGDR reducing risk by 27–30% after adjustment for multiple confounders.
As people age, they lose muscle mass, especially the type of muscle that uses sugar most efficiently. This makes it harder for the body to control blood sugar, causing insulin resistance. High insulin resistance forces the heart to burn fat instead of sugar, which damages heart muscle cells and causes the heart wall to stiffen. This stiffness prevents the heart from filling properly with blood, leading to heart failure.
What the research says
1 studyThis study found that older adults with better insulin sensitivity (measured by waist size, blood sugar, and blood pressure) had a much lower risk of heart failure — about 27–30% lower for each step up in insulin sensitivity, even after accounting for other health issues.
