Hypertension in acute ischemic and haemorrhagic stroke

ABSTRACT

To know the pattern of systolic and diastolic blood pressure in hypertensive patients with acute ischemic and hemorrhagic stroke. Material and This study was conducted on 100 patients with acute stroke, admitted in Khyber Teaching Hospital from July 2000 onward. Hypertensive patients were finally selected for analysis. BP was recorded at arrival and 24 hours after admission. Out of 100 patients with stroke, hypertension was present in 72 cases. Out of these 72 patients, 44 cases [61.1%] had cerebral infarction [CI] and 28 cases [38.9%] had cerebral haemorrhage [CH]. Overall mean systolic BP at arrival [SBP-A] was 163 [ +/- 35.606] mm Hg. Mean SBP-A in patients with CI was 152.3 [ +/- 34.397] mm Hg and in patients with CH was 181.25 [ +/- 30.357] mm Hg. Overall 68% of hypertensive stroke patients had uncontrolled systolic BP at arrival. Overall mean diastolic BP at arrival [DBP-A] was 95. 97 [ +/- 20.733] mm Hg. Mean DBP-A in CI was 88.75[ +/- 17.854] mm Hg and in CH was 107.32[ +/- 20.115] mm Hg. The mean difference of DBP-A in CH and CI was 18.57mm Hg. Mean systolic BP and Mean diastolic BP, 24 hours after admission were 157.85 mm Hg and 92.08 mm Hg respectively. Majority of hypertensive stroke patients have uncontrolled blood pressure. Hypertension is a risk factor for both ischemic and hemorrhagic stroke. More elevation of blood pressure is more frequently associated with cerebral hemorrhage than cerebral infarction
