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.

| Grade | Outcome | Effect | Size | Studies | People | Studies 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 effect | 45 studies | |||
| 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 effect | 44 studies | |||
| Vasopressor Dose Reduction ATHOS-3: Significant reduction in background vasopressor requirements. Catecholamine-sparing effect allows reduction of norepinephrine doses. May reduce catecholamine toxicity. | Improves (the measure goes down) | Moderate effect | 44 studies | |||
| 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. | NoneNo effect | 44 studies | ||||
Key findings
- Thromboembolic EventsWorsens (the measure goes down)
- Mean Arterial Pressure ResponseImproves (the measure goes up)
- Vasopressor Dose ReductionImproves (the measure goes down)
Safety notes in the studies
- May reduce catecholamine toxicity.
