BACKGROUND: High blood pressure (BP) is common in acute stroke and a predictor of poor outcomes. Treatment of acute stroke, before a distinction can be made between ischemic and hemorrhagic types, is challenging. We aimed to assess whether patients with presumed acute stroke benefit from pre-hospital BP lowering.
METHODS: We conducted a comprehensive systematic review and meta-analysis of randomized controlled trials from PubMed, Web of Science, Scopus, and Cochrane searches until June 2024. Dichotomous data were pooled using risk ratio (RR), and continuous data were pooled using mean difference (MD), both with a 95% confidence interval (CI), using (R version 4.3).
PROSPERO ID: CRD42024560200.
RESULTS: Our analysis included five RCTs encompassing 3,933 patients. There was no difference between early BP control and usual care regarding National Institutes of Health Stroke Scale (NIHSS) after 24 hours (MD: 0.65 with 95% CI [0.01, 1.29], P = 0.05), excellent neurological recovery (Modified Rankin Score (mRS) 0-1) (RR: 1.00 with 95% CI [0.91, 1.11], P= 0.98), functional independence (mRS 0-2) (RR: 1.04 with 95% CI [0.96, 1.13], P= 0.30), and independent Ambulation (mRS 0-3) (RR: 1.01 with 95% CI [0.95, 1.06], P= 0.84). Also, there was no difference between both groups in poor neurological recovery (mRS 4-6) (RR: 0.98 with 95% CI [0.91, 1.07], P= 0.68), all-cause mortality (RR: 1.02 with 95% CI [0.90, 1.15], P= 0.79), and any serious adverse events (RR: 1.04 with 95% CI [0.95, 1.15], P= 0.40). However, early BP control significantly increased the incidence of hypotension (RR: 2.24 with 95% CI [1.14, 4.38], P= 0.02) and headache (RR: 1.51 with 95% CI [1.01, 2.26], P= 0.04).
CONCLUSION: In patients with presumed hyperacute stroke and elevated blood pressure, the rapid initiation of blood pressure reduction in the ambulance very early after symptom onset had no significant benefit regarding functional outcomes in patients with undifferentiated stroke but with an increased incidence of hypotension and headaches.
