Psychosocial stimuli and human plasma renin activity

DM Clamage, AJ Vander and DR Mouw

The effects of several types of acute psychosocial stimuli on plasma renin activity (PRA) were studied in normotensive healthy subjects. Puzzle-solving produced an increase in blood pressure but no significant change in PRA, although two of seven subjects did respond with large increases in PRA. Watching a disturbing movie also raised blood pressure, but did not alter PRA. In contrast, a combination of novelty, fear, and/or anticipation did constitute a significant stimulus for renin secretion; this was evidenced by the fact that naive subjects (who were not told in advance what to expect) had significantly higher PRAs on the first day of the 2-day puzzle-solving study. PRA on this day correlated strongly with anxiety proneness, as did the decrease from day 1 to day 2. We conclude that meaningful psychosocial stimuli can enhance renin secretion in susceptible individuals.
