Measure
Higher Systolic Blood Pressure (SBP) Target
Lower systolic blood pressure to ≤180 mmHg and maintain for 24 hours. If anti-hypertensive medication used, then maintain ≥160 mmHg. Nicardipine: In the event where SBP values are above the randomly assigned target, intravenous nicardipine will be initiated at 2.5 mg/hr to lower the SBP. If SBP is still not reduced to below assigned target after 15 minutes, nicardipine dose will be increased by 2.5 mg/hr every 15 minutes until the target SBP or a maximum dose of 15 mg/hr is reached. Labetalol: If SBP is above target despite maximum nicardipine infusion for 30 minutes, 10-20 mg of intravenous labetalol will be added every 15 minutes. Hydralazine: If SBP remains unresponsive for 1 hr despite the use of maximum doses of nicardipine and labetalol, a Hydralazine will be added at the treating physician's discretion. Incidence of the latter scenario is anticipated to be exceedingly rare.
Lower SBP (<160 mmHg) Target
Lower systolic blood pressure to \<160 mmHg and maintain for 24 hours. If anti-hypertensive medication used, then maintain \>140 mmHg. Nicardipine: In the event where SBP values are above the randomly assigned target, intravenous nicardipine will be initiated at 2.5 mg/hr to lower the SBP. If SBP is still not reduced to below assigned target after 15 minutes, nicardipine dose will be increased by 2.5 mg/hr every 15 minutes until the target SBP or a maximum dose of 15 mg/hr is reached. Labetalol: If SBP is above target despite maximum nicardipine infusion for 30 minutes, 10-20 mg of intravenous labetalol will be added every 15 minutes. Hydralazine: If SBP remains unresponsive for 1 hr despite the use of maximum doses of nicardipine and labetalol, a Hydralazine will be added at the treating physician's discretion.

PRIMARY outcome

Timeframe: 90 days after treatment initiation

Modified Rankin score (mRS) is a scale for measuring the degree of disability or dependence of people who have suffered a stroke. 0 - no symptoms at all; 1 - no significant disability despite symptoms; able to carry out all usual duties and activities; 2- slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance; 3- moderate disability; requiring some help, but able to walk without assistance; 4 - moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance; 5 - severe disability; bedridden, incontinent and requiring constant nursing care and attention; 6- dead. Patient centered utility weights are applied to these scores as 1.0 for mRS level 0; 0.91 for mRS level 1; 0.76 for mRS level 2; 0.65 for mRS level 3; 0.33 for mRS level 4; 0 for mRS level 5; and 0 for mRS level 6. Unlike the mRS, the utility-weighted mRS runs from 0 to 1, with 0 being the worst.
