Blood Pressure Management in Acute Cerebrovascular Diseases

Introduction to Blood Pressure Targets

The American Heart Association recommends that blood pressure should generally NOT be treated unless systolic BP exceeds 220 mmHg or diastolic BP exceeds 120 mmHg in patients with acute ischemic stroke not receiving thrombolytic therapy 1, 2
The European Society of Cardiology suggests that if treatment is required, reduce blood pressure by approximately 15% during the first 24 hours, avoiding precipitous drops 3

The American Heart Association recommends that before thrombolysis, BP must be <185/110 mmHg in patients with acute ischemic stroke receiving thrombolytic therapy 4, 3
The American Heart Association suggests that during and after thrombolysis, maintain BP <180/105 mmHg for 24 hours in patients with acute ischemic stroke receiving thrombolytic therapy 1
The American Heart Association recommends the following BP monitoring schedule after rtPA administration in patients with acute ischemic stroke:

The American Heart Association recommends that for patients with mild to moderate intracerebral hemorrhage and systolic BP between 150-220 mmHg, target systolic BP of 140 mmHg (maintaining in the range of 130-150 mmHg) 5, 6
The American Heart Association suggests that initiate BP treatment within 2 hours of intracerebral hemorrhage onset and reach target within 1 hour to reduce hematoma expansion risk 5, 6
The American Heart Association recommends avoiding lowering systolic BP below 130 mmHg as this is potentially harmful in patients with intracerebral hemorrhage 5, 6

The European Society of Cardiology recommends that first-line agents for acute BP management include labetalol and nicardipine, which have reliable dose-response relationships and safety profiles 1, 3
The European Society of Cardiology suggests that labetalol is preferred for patients with tachycardia, and nicardipine is preferred for patients with bradycardia, heart failure, or bronchospasm 1

The American Heart Association recommends continuous BP monitoring for patients requiring IV antihypertensive medications 1, 7
The American Heart Association suggests that for patients with intracerebral hemorrhage, frequent BP checks are needed to avoid large fluctuations 5, 6
The Society of Critical Care Medicine recommends that in patients with impaired consciousness or high stroke severity, more intensive monitoring may be required 8, 7
