The Claim
In community-dwelling adults aged 60–85 with preserved cardiac function, a faster annual decline in appendicular lean mass (25.1 g/year) is independently associated with a faster annual decline in left ventricular mass (0.73 g/year) after adjustment for age, sex, blood pressure, and body mass index.
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 with healthy heart function, people who lose skeletal muscle faster also lose heart muscle faster at a consistent rate, even when accounting for age, sex, blood pressure, and body weight.
See the scientific wording
In community-dwelling adults aged 60–85 with preserved cardiac function, a faster annual decline in appendicular lean mass (25.1 g/year) is independently associated with a faster annual decline in left ventricular mass (0.73 g/year), even after adjusting for age, sex, blood pressure, and body mass index, suggesting shared biological aging processes between skeletal and cardiac muscle tissues.
As people age, chronic low-grade inflammation and the buildup of damaged cells in muscles trigger fibrosis and reduce the ability of both arm and heart muscles to repair themselves, causing them to shrink at similar rates.
What the research says
1 studyIn older adults without heart disease, people who lose arm muscle faster also tend to lose heart muscle faster over time — even when you account for age, weight, and blood pressure — suggesting both muscles may age together due to similar underlying processes.
