Title: Scandinavian Candesartan Acute Stroke Trial
Brief Summary: The purpose of this trial is to assess whether the blood pressure lowering agent candesartan (an angiotensin receptor type 1 blocker) is effective when given to patients with acute stroke and elevated blood pressure.

Hypothesis:

AT1 receptor blockade with candesartan in acute stroke will:

1. reduce the risk of death or major disability at 6 months by a 6% absolute risk reduction, relative to placebo.
2. reduce the risk of the combined event of "vascular" death, myocardial infarction, or stroke during the first 6 months by a 25% relative risk reduction, relative to placebo


Options:
A: Inclusion Criteria:

* Age 18 years or older
* IV nicardipine can be initiated within 4.5 hours of symptom onset.
* Clinical signs consistent with the diagnosis of stroke, including impairment of language, motor function, cognition, and/or gaze, vision, or neglect.
* Total Glasgow Coma Scale (GCS) score (aggregate of verbal, eye, and motor response scores) of 5 or greater at time of emergency department (ED) arrival.
* International normalized ratio (INR) value \< 1.5
* CT scan demonstrates intraparenchymal hematoma with manual hematoma volume measurement \<60 cc.
* For subjects randomized prior to IV antihypertensive administration: SBP greater than 180 mmHg\* prior to IV antihypertensive treatment (this includes pre-hospital treatment) AND WITHOUT spontaneous SBP reduction to below 180 mmHg at the time of randomization OR
* For subjects randomized after IV antihypertensive administration: SBP greater than 180 mmHg\* prior to IV antihypertensive treatment (this includes pre-hospital treatment) AND WITHOUT SBP reduction to below 140 mmHg at the time of randomization.
* Informed consent obtained by subject, legally authorized representative, or next of kin.

  * Notes: The unit "mmHg" stands for "millimeters of mercury", a standard way of measuring blood pressure. Patients with SBP \< 180 mmHg should be monitored for 4.5 hours from symptom onset as their SBP may rise to eligible levels before the eligibility window closes.

Exclusion Criteria:

* ICH is due to previously known neoplasms, arteriovenous malformation (AVM), or aneurysms.
* Intracerebral hematoma considered to be related to trauma.

7. Coiling material used, which has not been approved by local health authorities.
8. Use of liquid embolism aneurysmal treatment or flow diverting device.

    * "Large territorial infarct" refers to infarcts detected during the endovascular coiling procedure or immediately post-procedure (i.e., CT performed for suspicion of cerebral infarct or other complication). This does not imply having to wait 24-48 hours post-procedure to perform the protocol-mandated CT scan in order to randomize a patient. Evaluation for a new major neurological deficit post-procedure implies reversal of sedation and performance of a GCS examination (verbal scores in intubated patients may be extrapolated from the eye-opening and motor scores using predefined values). If a new major neurological deficit does not improve within 12 hours after the coiling procedure, the patient cannot be included.
