Blood Pressure Goals in Acute Stroke-How Low Do You Go?

Area of Science:

• Neurology
• Cardiology
• Emergency Medicine

Background:

• Elevated systolic blood pressure (BP) > 140 mmHg is common in acute ischemic stroke (75%) and intracerebral hemorrhage (ICH) (80%).
• Managing hypertension in acute stroke patients is critical for patient outcomes.

Purpose of the Study:

• To summarize and update current knowledge on managing elevated BP in acute stroke patients.
• To differentiate management strategies for ischemic stroke versus ICH.

Main Methods:

• Review of recent clinical trials and current guidelines.
• Analysis of evidence for BP reduction effects on stroke outcomes.

Main Results:

• BP reduction shows neutral effects on clinical outcomes in acute ischemic stroke.
• Guidelines recommend BP < 180/105 mmHg for ischemic stroke patients receiving intravenous thrombolysis, but optimal post-reperfusion BP is unclear.
• Randomized trials support immediate BP lowering to target systolic BP of 140 mmHg in acute ICH.

Conclusions:

• Aggressive BP reduction is not recommended for acute ischemic stroke due to lack of supporting evidence.
• Current guidelines recommend targeting systolic BP to 140 mmHg for acute intracerebral hemorrhage management.
