In this study, we examined whether large blood pressure reductions are associated with hypoperfusion and ischemia in the perihematomal region in acute intracerebral hemorrhage (ICH) patients. Perfusion and diffusion weighted imaging were performed within 24 hours of ICH onset. Hourly blood pressures were recorded from hospital admission to MRI. Hypoperfusion and presence of diffusion lesions in the perihematomal region were found to be associated with the absolute and percent degree of reduction from admission systolic blood pressure to mean treated systolic blood pressure.
