Condition

Septic Shock

Septic shock is a life-threatening drop in blood pressure after a severe infection, when widened, leaky blood vessels leave organs short of blood flow. Angiotensin II, a hormone that tightens blood vessels, has strong evidence behind it: in one trial, 70% of people reached a target blood pressure within three hours, versus 23% on placebo. Those participants had shock that resisted standard drugs, so results mostly apply to that group.

GradeOutcomeEffectSizeStudiesPeopleStudies list
Thromboembolic Events

SAFETY CONCERN: ATHOS-3: 13% vs 5% thromboembolic events (DVT, arterial). Major imbalance in DVT. Concurrent DVT prophylaxis required. Systematic review (n=1,461): Similar rates in larger observational data (8.8% vs 9.4% VTE).

Worsens (the measure goes down)Moderate effect45 studies

and 42 more on the Angiotensin II page

Mean Arterial Pressure Response

ATHOS-3 (n=321): 70% achieved MAP ≥75 mmHg or ≥10 mmHg increase at 3h vs 23% placebo (P<0.001). 45% absolute increase in responders. Effective in catecholamine-resistant shock.

Improves (the measure goes up)Large effect44 studies

Vasopressor Dose Reduction

ATHOS-3: Significant reduction in background vasopressor requirements. Catecholamine-sparing effect allows reduction of norepinephrine doses. May reduce catecholamine toxicity.

28-Day Mortality

ATHOS-3: No significant mortality difference (46% vs 54%, P=0.12). Study not powered for mortality. Post-hoc AKI/RRT subgroup: 53% vs 30% survival (P=0.012). Mortality benefit uncertain.
