The Claim
Individuals older than 65 years with both low appendicular skeletal muscle mass and elevated insulin resistance have a nearly doubled risk of developing heart failure compared to those with moderate-stable levels of both measures, independent of age, sex, and cardiovascular comorbidities.
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.
Older adults with low muscle mass in their arms and legs and high insulin resistance have twice the risk of heart failure compared to those with moderate levels of both, even when accounting for age, sex, and other heart conditions.
See the scientific wording
The combined effect of low appendicular skeletal muscle mass and elevated insulin resistance synergistically increases heart failure risk in older adults, with individuals exhibiting both low-stable ASMI and low-stable eGDR having nearly double the risk compared to those with moderate-stable levels, even after adjusting for age, sex, and cardiovascular comorbidities.
As muscle mass decreases with age, the body loses key tissues that use sugar for energy, causing blood sugar to stay high for longer. This high sugar environment damages the heart's ability to use energy properly, forcing it to burn fat instead, which builds up as toxic fat deposits inside heart cells. Over time, the heart muscle thickens abnormally and becomes stiff, making it harder to pump blood, which leads to heart failure.
What the research says
1 studyOlder adults who have both low muscle mass and poor insulin sensitivity over time are almost twice as likely to develop heart failure as those with moderate levels of both, even when other health issues are taken into account.
