Cardiovascular disease risk factor management may help preserve physical function as we age
Overview
Managing cardiovascular disease (CVD) risk factors may play a role in preserving physical function during the aging process, according to new research published by The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences.
“Approximately 10% of older adults have muscle weakness and diminished physical function that leads to adverse health outcomes and physical disability,” said lead author Dr. Shivani Sahni. “Since loss of physical function contributes to reduced mobility, disability, institutionalization, and mortality, management of CVD risk factors can help preserve physical function with age,” said Dr. Sahni.
This study showed that vascular measures are associated with grip strength in cross-sectional analyses and change in gait speed (a measure of physical function) in longitudinal analyses.
Higher aortic stiffness was associated with loss of physical function over ~11 years, said Dr. Sahni, who is an Associate Professor of Medicine at Harvard Medical School .
Blood flow declines with aging, in part due to arterial stiffening. Consequent dysfunction in blood vessel dynamics may contribute to organ pathology and declines in muscle mass, explains Dr. Sahni. The current study utilized data from a large cohort of relatively healthy men and women and extends previous investigations by utilizing a longitudinal study design.
