A Spontaneous Decrease of Blood Pressure Occurs in Acute Ischemic Stroke with Favourable Neurological Course

Table 4: Basal BP measurement and 24-hour BP monitoring during the first and sixth day from stroke onset. Results are given in relation to early neurological improvement severity of stroke (group C and group D, as previously defined). Figures represent mean ± SE. SBP = Systolic blood pressure, DBP = Diastolic blood pressure, HR = Heart rate, PP = pulse pressure
