Controlling Hypertension After Severe Cerebrovascular Event
A Multi-center Randomised Controlled Trial to Explore the Ideal Individualized Anti-hypertension Strategies in Patients With Severe Stroke at Acute Stage
The purpose of this academic lead study is to explore ideal blood pressure targets and optimum individualized anti-hypertension strategies in acute severe stroke.

Of high mortality and morbidity, severe stroke is associated with devastating damages in neurologic, respiratory, circulatory and many other systems. The outcomes of patients with severe stroke depend largely on medical strategies on acute stage, especially on blood pressure (BP) management. Unfortunately, so far no ideal BP range has been scientifically determined for patients with acute severe stroke.

The CHASE study aims to provide reliable data on the effects of individualized anti-hypertension strategy in patients with acute severe stroke (target recruitment 250) compared to standard guideline-based management of BP (target recruitment 250). Patients presenting with acute (<72h) severe stroke (GCS ≦ 12 or NIHSS ≧ 11) and elevated BP (systolic blood pressure ≧150 mmHg or diastolic blood pressure ≧ 100 mmHg) will be randomly assigned to individualized anti-hypertension treatment or guideline-based treatment for 7 days.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
  • Severe Stroke
  • Acute Stroke
  • Hypertension
Other: Blood pressure management policies
Other Names:
  • Labetalol Hydrochloride
  • Metoprolol tartrate
  • Hydralazine Hydrochloride
  • Glycerol Trinitrate
  • Phentolamine mesylate
  • Nicardipine
  • Urapidil
  • Esmolol
  • Clonidine
  • Enalaprilat
  • nitroprusside
  • Experimental: Individualized BP lowering
    Management policy is to lower the systolic or diastolic BP by 10-15% within 24 hours of randomization and sustained for 7 days. Sites were provided with protocols for different intravenous agents and used whichever routinely available drugs were in their hospital.
    Intervention: Other: Blood pressure management policies
  • Active Comparator: Guideline recommended BP lowering
    Patients received management of BP based on the standard guidelines at the time, as published by the Chinese Society of Neurology (CSN) in 2014. The attending clinician may consider commencing BP treatment and sustained for 7 days if the systolic BP > 200 mmHg or diastolic BP >110 mmHg in patients with ischemic stroke, and systolic BP > 180 mmHg or diastolic BP > 110 mmHg in patients with cerebral hemorrhage.
    Intervention: Other: Blood pressure management policies
