Arterial hypertension in acute stroke. Current therapeutical indications

Abstract

Acute stroke (the first hours after its onset) is accompanied in over 70% of cases by rapid and significant increases in blood pressure, above normal values. The acute or reactive hypertensive response occurs both in patients with a history of hypertension and in normotensive patients. The greatly increased BP values, not controlled therapeutically, can be followed by the increase in the volume of the cerebral infarct and hemorrhagic transformation or the expansion of the hematoma and the increase in intracerebral pressure, respectively in ischemic or hemorrhagic stroke. This paper especially refers to the therapeutic control of hypertension in various situations (conditions): 1. Laboratory emergencies; 2. Hospital treatment with out thrombolytics or thrombolysis; 3. Endovascular treatment in acute stroke; 4. BP control in hemorrhagic stroke; 5. Continuation or discontinuation of antihypertensive treatment. The updated recommendations for the treatment of HTN in acute stroke result from clinical studies and recommendations of the recent ESO and AHA/ASA Guidelines.
