Randomized Controlled Trial Multicenter Study
The speed of ultraearly hematoma growth in acute intracerebral hemorrhage.
The prognostic importance of the speed of early hematoma growth in acute intracerebral hemorrhage (ICH) has not been well established. We aimed to determine the association between the rate of increase in hematoma volume and major clinical outcomes in the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT) studies. The effects of early intensive blood pressure (BP) lowering according to the speed of hematoma growth were also investigated. ⋯ The speed of UHG in patients with ICH was continuously associated with increased risks of death or major disability, and from lower levels than previously reported (≥5 mL/h). The benefits of intensive BP lowering appear to be independent of the speed of bleeding.
