    AbstractThe optimal management of blood pressure (BP) during acute stroke is controversial. We aimed to investigate whether (1) acute BP has differential impact on clinical outcome of ischemic stroke (IS) and spontaneous intracerebral hemorrhage (ICH), and (2) the magnitude of such an effect varies from the very acute phase to the postacute phase of the two diseases. BP values were automatically recorded at 15-min intervals within the first 48 h in consecutive patients with stroke onset less than 24 h before Stroke Unit admission. Growth mixture models were applied to evaluate the association between binary outcome measures [(1) early neurological deterioration (defined as a ≥4-point increase in 48-h National Institutes of Health Stroke Scale [NIHSS] score), (2) 90-day unfavorable functional status (modified Rankin Scale [mRS] 3-6), and (3) 90-day mortality] and the latent heterogeneity of maximum BP trajectories over time, expressed by two (high/low) BP latent classes within stroke groups. After exclusions, 264 patients (198 IS, 66 ICH) were included. High systolic BP (sBP) class was associated with (1) a direct ~15% increased risk of early neurological deterioration [risk difference (RD), +0.151; 95% confidence interval (CI) +0.039 to +0.263] and ~4% worse 48-h outcome for ICH with respect to IS (RD, +0.038; 95% CI +0.005 to +0.071), (2) a ~28% increased risk of 90-day unfavorable outcome in the group of patients with ICH with respect to IS [IRD = RD(ICH) - RD(IS), +0.289; 95% CI +0.010 to +0.571], and (3) no significant effect on 90-day mortality. The influence of acute BP values on mid-term stroke outcome varies depending on the stroke subtype.
