Blood Pressure Lowering in Acute Stroke Trial (BLAST)

Summary

Patients who are suffering from a stroke often present to the hospital with elevated blood pressure. Elevated blood pressure in the setting of stroke increases the risk of brain swelling or bleeding into the brain. Even so, there has been concern about lowering the blood pressure with medications because the newly injured parts of the brain may not get the blood flow they need, thereby worsening the damage from the initial stroke. We hope to demonstrate that the drug valsartan can be used safely and modestly to lower blood pressure in acute stroke patients, without having a detrimental effect on brain blood flow or neurologic status. Novel MRI techniques to measure brain blood flow will be used in conjunction with clinical scales to demonstrate safety.
