Abstract
Background
Blood pressure (BP) management at the initial stage of stroke caused by large-vessel occlusion (LVO) remains challenging. We assessed the association between baseline BP and clinical and safety outcomes of endovascular treatment (EVT) in different stroke etiologies.
Methods
Patients with acute ischemic stroke and anterior circulation LVO were screened from a prospective, multicenter registry of EVT from November 2017 to March 2019. The primary outcome was poor 90-day outcome (modified Rankin Scale score 3–6). The safety outcome was 24 h post-procedure parenchymal hematoma (PH). The Trial of Org 101072 in Acute Stroke Treatment criteria were used for etiologic stroke classification. Restricted cubic spline and binary logistic regression analysis were performed to examine the association between study outcomes and natural log-transformed BP.
Results
In subgroup analyses, a U-shaped correlation existed between baseline mean arterial pressure (MAP) and poor outcome in large-artery atherosclerosis stroke only. Higher MAP was an independent risk factor compared with a central reference value (≥ 133 mm Hg vs 96–115 mm Hg; adjusted OR [aOR], 2.50; 95 % CI, 1.09 to 5.71, P = 0.030). Whereas elevated MAP was associated with PH (aOR, 1.58; 95 % CI 1.04 to 2.39, P = 0.030 for a ln10-unit increase in natural log-transformed MAP) in the range <110 mm Hg exclusively for cardioembolic stroke.
Conclusion
Whether it is cause or epiphenomenon, baseline BP was associated with 90-day outcome in large-artery atherosclerosis stroke, whereas in cardioembolic stroke baseline BP was correlated with post-procedure PH within a certain range. Identifying these features based on etiological subtypes may offer a reference for BP management in acute LVO stroke.
