Supports differential genetic effects on BP reactivity by stressor in older adults; leaves open replication and outcome links.
Do genetic factors influence cardiovascular reactivity to cold and mental activity in late adulthood?
Genetic factors significantly contribute to blood pressure reactivity during mental stress, but not cold stress, in older men.
