Question

--Aggressive BP management (SBP <140) in atraumatic intracerebral hemorrhage (ICH) does NOT signifcantly improve mortality or disability compared with traditional goal (SBP <180) [1]

--However, a lower goal (SBP <140) has been shown to decrease hematoma size and be safe compared to a higher goal (SBP <180) [2]

Answer

The recently published ATACH-2 study investigated aggressive BP control in hypertensive acute atraumatic ICH/IPH (intraparenchymal hemorrhage). [1]

--Control group SBP 140-179 mmHg vs. intervention group SBP 110-139 mmHg with nicardipine infusion (control group actually had SBP 140-150 vs. intervention group SBP 120-130 most of the time).

--Study stopped early for futility. No difference in mortality or modified Rankin.

Previously, INTERACT2 demonstrated that aggressive SBP management (<140) was safe, decreasing hematoma expansion leading to a change in some individuals' practice. [2]
