Implication

Does not support clinical use in hypertension; leaves open translation of vascular protection from rat models to humans.

Key Points

This study investigates how potassium supplementation affects mortality and hemorrhage in hypertensive rats, independent of blood pressure reduction.
Studied stroke prone spontaneously hypertensive rats and hypertensive Dahl salt-sensitive rats.
Compared groups receiving K+ supplements to control groups with no K+ supplements.
Measured mortality rates and incidence of cerebral hemorrhage between groups.
Potassium reduced mortality from 83% to 2% in spontaneously hypertensive rats (98% reduction).
A 40% incidence of cerebral hemorrhage was observed in rats not receiving K+, while none occurred in K+ recipients.
Dahl salt-sensitive rats showed a mortality reduction from 55% to 4% with K+ supplementation (93% reduction).
