This study examined the renal and blood pressure effects of an
acute IV salt load given over 3 hours to young and old
normotensive patients. The salt load caused a marked rise in
blood pressure, especially systolic, in the elderly patients but
not in the young subjects. The increase in BP was found despite
the fact that the elderly excreted significantly more sodium
during the 6 hour study period, persumably due to a pressure
natriuresis. The data suggest that elderly patients are
susceptible to increased blood pressure with salt loading. The
presumptive mechanism is a decrease in vascular compliance.
