What is the target systolic blood pressure (SBP) for an older adult patient with a history of hypertension and cardiovascular disease experiencing a cerebrovascular bleed, such as an intracerebral hemorrhage, while on anticoagulant or antiplatelet therapy?

Target Systolic Blood Pressure for Acute Intracerebral Hemorrhage

For patients with acute intracerebral hemorrhage (ICH), target a systolic blood pressure of <140 mmHg, initiated as soon as possible and maintained acutely, as this reduces hematoma expansion and improves functional outcomes without compromising cerebral perfusion. 1

Acute Management Target

• Lower systolic BP to <140 mmHg acutely in patients with spontaneous ICH who present with elevated blood pressure (SBP ≥150 mmHg). 1
• This target should be achieved rapidly, ideally within the first 6 hours of hemorrhage onset, as earlier intervention shows trends toward improved outcomes. 2
• The previous conservative threshold of maintaining SBP <180 mmHg is outdated and insufficient for optimal outcomes. 2

Evidence Supporting Intensive Control

The recommendation for SBP <140 mmHg is based on:

• Recent pivotal trials demonstrating that acute BP reduction to approximately 140 mmHg is beneficial when bundled with comprehensive ICH care (neurosurgery when indicated, critical care access, glucose control, temperature management, coagulopathy reversal). 1
• Reduction of mean arterial pressure by 15% does not result in cerebral blood flow reduction as measured by positron emission tomography. 2
• Cerebral perfusion pressure should be preserved at >60 mmHg during BP lowering. 2

Special Considerations for Older Adults on Antithrombotic Therapy

For elderly patients (≥65 years) with ICH on antiplatelet or anticoagulant therapy, the same SBP target of <140 mmHg applies, but these patients require more intensive monitoring due to higher risk profiles:

• Patients on antithrombotic therapy have significantly stronger associations between elevated prehospital systolic BP and poor outcomes (in-hospital mortality OR 1.14 per 5 mmHg vs 0.99 in non-users, P=0.021). 3
• Elderly patients with severe ICH may benefit more from individualized BP-lowering treatment compared to younger counterparts, with improved functional independence at 90 days (21.6% vs 8.2%, OR 4.309). 4
• The combination of antithrombotic therapy and elevated BP creates a particularly dangerous scenario for hematoma expansion and mortality. 3

Critical Pitfalls to Avoid

Do not allow BP to drop too rapidly or too low:

• Rapid decline in BP during acute hospitalization has been associated with increased death rates. 2
• Maintain cerebral perfusion pressure >60 mmHg at all times. 2
• Avoid reducing mean arterial pressure by more than 15% initially. 2

Do not delay treatment:

• Elevated systolic BP is associated with hemorrhagic expansion, though the exact causal relationship remains debated. 2
• Patients in whom SBP was lowered within 6 hours showed trends toward improved outcomes. 2

Monitoring Requirements

• Use continuous intravenous BP monitoring for patients requiring continuous antihypertensive medications or those with deteriorating neurological status. 2
• Assess neurological status frequently using standardized scales (NIHSS, GCS). 2
• Monitor for signs of cerebral hypoperfusion, particularly in patients with increased intracranial pressure. 2

Long-Term Management Context

While the acute target is <140 mmHg, recognize that chronic hypertension management differs:

• For general elderly patients (≥65 years) with chronic hypertension, targets of 130-139 mmHg are appropriate. 5, 6
• However, the acute ICH setting requires more aggressive initial control to prevent hematoma expansion. 1
