Admission Blood Pressure As a Prognostic Marker in Acute Ischemic Stroke.

Abstract

Objective: To evaluate the relationship between Blood pressure (systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure) on admission and early mortality and morbidity in acute stroke patients and to see the prognostic significance of BP with mortality and morbidity in inpatients Design: Hospital based prospective observational study Setting: Conducted in the Department of General Medicine at Sri Devaraj Urs medical college, Kolar, Karnataka. Subjects: A total of 100 patients admitted within24 h from stroke. Main outcome measures are Mortality at 1 and 3day after stroke in relation to admission SBP and DBP. Results: 77.8% Mortality was seen in the subjects who had admission SBP of 161-180mmhg. 75% Mortality was seen in the subjects who had admission SBP>180mmhg. Both the extremity low and high admission SBP had very high mortality. 60% Mortality was seen in the subjects who had admission DBP 60-69mmhg. 85.7% Mortality was seen in the subjects who had DBP >110mmhg. Both the extremity low and high admission DBP had very high mortality. Conclusion: The described U-shaped curve appears to relate BP to clinical outcome, with the best outcome observed in normal or mildly elevated admission BP values, suggesting that both extremely high and extremely low admission BP-values are likely to affect outcome adversely.
