Blood Pressure Measurement and Antihypertensive Therapy in Acute Stroke

Inappropriate management of high blood pressure in acute stroke can adversely affect outcome. We examined blood pressure evaluation and antihypertensive therapy during the first week post-stroke in 40 patients at a district general hospital with no stroke unit. In the first 24 hours, median frequency of blood pressure recording was 3 (range 1-12). After day 1, 11 (28%) had no blood pressure readings for one or two consecutive days. The side of measurement was not recorded in any patient. None of the 22 hypertensives (55%) had a bilateral measurement to exclude interarm inequality, and only 3 (7%) of all patients had postural readings to exclude orthostatic hypotension. Fourteen (35%) received antihypertensive therapy without meeting recommended indications; some even had low blood pressure. As most stroke patients are managed in general medical wards rather than stroke units, a greater awareness of these important aspects of blood pressure evaluation and therapy are needed among medical and nursing staff.
