Abstract

The optimal target of blood pressure (BP) in the acute phase of intracranial haemorrhage (ICH) is still controversial. Our aim was to evaluate safety and efficacy of intensive BP lowering compared to standard BP treatment in ICH. We conducted a systematic review and meta-analysis of all available randomized controlled trials recruiting patients with elevated BP in acute spontaneous ICH to intensive or standard BP-lowering treatment. Our primary outcomes were 3-month mortality, disability (modified Rankin Scale 3–5) and combined death or disability. Secondary outcomes were early neurological deterioration at 24 h, substantial haematoma enlargement within 24–72 h and 3-month non-fatal serious adverse events. We included six studies for a total of 4385 patients (mean age 62 years, 62.3% men). No differences were detected between the two treatment groups in 3-month mortality (RR = 0.99, 95% CI 0.83–1.17), disability (RR = 0.96, 95% CI 0.89–1.03) and combined death and disability (RR = 0.97, 95% CI 0.90–1.03). The rate of patients with early neurological deterioration, substantial haematoma enlargement and non-fatal serious adverse events was similar in the two treatment groups (RR = 1.03, 95% CI 0.88–1.19, RR = 0.85, 95% CI 0.70–1.03, RR = 1.07, 95% CI 0.90–1.28, respectively). An intensive BP control in the acute phase of ICH is not beneficial and should not be recommended. Therefore, the systolic BP target of less than 140 mmHg that is now suggested by guidelines needs to be reconsidered.
