The impact of intensive blood pressure management in the post-thrombolysis setting: a real-world observational study. Harper, B., Ranta, S., McNaughton, H., & Ranta, A.

Paper doi abstract bibtex aim: Systolic blood pressure (SBP) \textgreater180mmHg following stroke thrombolysis has been associated with increased bleeding and poorer outcome. Aiming for the guideline SBP of \textless180mmHg often leads to SBP overshoot, as treatment is only triggered if this threshold is passed. We tested whether a lower target would result in fewer high SBP protocol violations. method: This is a single-centre, sequential comparison of two blood pressure protocols. Between 2013 and 2017, the guideline-based post-thrombolysis SBP target of \textless180mmHg was compared with a new protocol aiming for 140–160mmHg. The primary outcome was rate of patients with SBPs \textgreater180mmHg. Secondary outcomes included rates of SBP \textless120mmHg, antihypertensive infusion use, symptomatic intracerebral haemorrhage (sICH) and 3-month functional independence (modified Rankin Score [mRS] 0–2). Results were adjusted for age, baseline function and stroke severity using regression analysis. results: During the 23 months preceding and 18 months following the transition to the new protocol, 68 and 100 patients were thrombolysed respectively. Baseline characteristics were similar between groups. The odds of one or more SBPs \textgreater180mmHg trended lower in the intensive group (adjusted odds ratio [aOR] 0.61; 95% confidence interval [CI] 0.32–1.17; p=0.14). There was a higher rate of SBPs \textless120mmHg (aOR 3.09; 95% CI 1.49–6.40; p=0.002) in the intensive BP protocol group. sICH rate and 3-month mRS 0–2 were similar between groups. conclusions: The more intensive post-thrombolysis BP protocol was associated with a significant increase in sub-optimally low BP events, with a non-significant trend toward fewer high BP protocol violations and unaffected patient outcomes.
