ACEIs may differentially affect salt sensitivity versus vasodilators in hypertension models; leaves open human translation and practice implications.
Does captopril or hydralazine alter arterial pressure-urinary output relationships in spontaneously hypertensive rats?
Captopril, unlike hydralazine, makes arterial pressure extremely salt-sensitive in spontaneously hypertensive rats, suggesting different mechanisms of long-term blood pressure control.
Kline et al. (1987) studied this question.
