ATHOS-3

Design International RCT, n=344
Published 2017 (NEJM)
Result Angiotensin II increased MAP response at 3 hours (69.9% vs 23.4%) in vasodilatory shock refractory to high-dose conventional vasopressors. No significant mortality difference at 28 days.
Practice impact Led to FDA approval of angiotensin II as a vasopressor; now used as a third-line agent in catecholamine-refractory vasodilatory shock.
