Elevated blood pressure (BP) is the leading modifiable risk factor for stroke and the benefit of BP lowering therapy on the stroke risk reduction is well established. The optimal BP target for preventing stroke and other vascular events have been controversial, but the evidences from epidemiological studies and randomized controlled trials (RCTs) support intensive BP lowering for greater vascular protection, particularly for stroke prevention. For secondary stroke prevention, the evidence of intensive BP lowering benefit is limited since only a single RCT for patients with lacunar infarctions was conducted and most data were driven by exploratory analyses. In acute intracerebral hemorrhage, immediate BP lowering targeting systolic BP<140 mm Hg is recommended by guidelines based on the results from RCTs. In contrast, in acute ischemic stroke, early BP lowering is not usually recommended because of no benefit on functional outcome and future vascular events and potential harm of stroke progression. This review aims to summarize the updated evidence for optimal BP management for primary and secondary stroke prevention and in patients with acute stroke.
