How Mutant Blood Stem Cells May Quietly Fuel Heart Disease as You Age
As people age, blood stem cells accumulate mutations that cause certain cell lines to expand. This process, called clonal hematopoiesis, is now strongly linked to increased cardiovascular risk in older adults. The mutant blood cells appear to ramp up inflammation, accelerating atherosclerosis and heart failure. This review covers how these rogue clones interact with age-related inflammation and what future therapies might look like.
Caloric Restriction Slows Aging Most in the Heart and Metabolism
Cutting calories doesn't slow aging evenly across all organs. In a two-year trial, 185 adults were randomly assigned to caloric restriction or normal eating. The caloric restriction group aged about one year less in their cardiovascular and metabolic systems over 24 months. Kidney aging, however, didn't budge, and liver aging only slowed modestly at the two-year mark.
