In acute spontaneous intracerebral hemorrhage (ICH), immediate blood pressure (BP) management plays a crucial role in minimizing hematoma expansion. Determining the exact target pressure requires balancing the risk of ongoing bleeding against cerebral hypoperfusion and end-organ damage. Guideline Recommendations
Per NICE guidelines, clinicians should rapidly reduce SBP to 130–140 mmHg within the first hour of initiating treatment. This target should be maintained for 7 days to stabilize the patient.
Key Trial Insights
INTERACT-2: Established that lowering SBP to around 140 mmHg is safe and improves functional outcomes compared to standard conservative management.
ATACH-2: Tested an aggressive SBP target of 110–130 mmHg. The trial revealed no significant advantage in functional recovery and noted a higher incidence of acute kidney injury and adverse events.
Practical Takeaway
For emergency and acute stroke teams, lowering SBP too slowly leaves the patient at risk for hematoma growth, while dropping SBP below 130 mmHg increases the risk of renal compromise and systemic hypotension. Aiming for 130–140 mmHg within 60 minutes strikes the optimal therapeutic balance.
