Abstract:
Objective:To explore the influence of blood pressure (BP) profiles 24 h after early endovascular treatment (EVT), including mean blood pressure and blood pressure variability, in clinical prognoses of patients with acute large vessel occlusion stroke (ALVOS) of anterior circulation 90 d after EVT.Methods:Clinical data and blood pressure profiles of patients with ALVOS of anterior circulation who received EVT in our hospital from July 2014 to February 2019 were prospectively collected. The 90-d modified Rankin scale (mRS) scores were used as clinical prognosis evaluation, and modified thrombdysis in cerebral infarction (mTICI) was used as evaluation criteria for recanalization of postoperative occlusive blood vessels. Multivariate Logistic regression analysis was used to determine the independent influencing factors for prognoses 90 d after EVT.Results:(1) Two hundred and sixteen patients were collected; 159 patients were with successful recanalization and 57 patients were with unsuccessful recanalization; 90 d after EVT, 95 patients (44%) had good prognosis and 121 patients (56%) had poor prognosis. As compared with patients in the good prognosis group, patients in the poor prognosis group had signficantly advanced age, signficantly higher proportion of patients with atrial fibrillation, signficantly higher baseline NIHSS scores, and signficantly lower baseline ASPECT scores ( P<0.05); and the differences of occlusion locus were statistically significant between patients from the good and poor prognosis groups ( P<0.05). Patients in the poor prognosis group had significantly higher baseline systolic blood pressure (SBP), mean SBP, max SBP, and significantly higher standard deviation, variable coefficient, and continuous variation of SBP, and statistically higher standard deviation, variable coefficient, and continuous variation of diastolic blood pressure (DBP) as compared with those in the good prognosis group ( P<0.05). Multivariable Logistic regression analysis showed that the standard deviation and continuous variation of SBP were independent influencing factors for clinical prognoses 90 d after EVT ( OR=1.116, 95%CI: 1.002-1.243, P=0.047; OR=1.116, 95%CI: 1.016-1.227, P=0.022). (2) In patients with successful recanalization, as compared with patients in the good prognosis subgroup, patients in the poor prognosis subgroup had signficantly advanced age, statistically higher proportions of patients with diabetes mellitus and atrial fibrillation and baseline NIHSS scores, and statistically lower baseline ASPECT scores ( P<0.05); and the differences of occlusion locus and first choices of treatment were statistically significant between patients in the good and poor prognosis subgroups ( P<0.05). Patients in the poor prognosis subgroup had significantly higher baseline SBP and max SBP, and significantly higher standard deviation, variable coefficient, and continuous variation of SBP, and statistically higher variable coefficient of DBP as compared with those in the good prognosis subgroup ( P<0.05). Multivariable Logistic regression analysis showed the standard deviation, variable coefficient, and continuous variation of SBP were independent influencing factors for clinical prognoses 90 d after EVT ( OR=1.164, 95%CI: 1.021-1.326, P=0.023; OR=1.191, 95%CI: 1.007-1.409, P=0.041; OR=1.141, 95%CI: 1.018-1.279, P=0.024). However, in patients with unsuccessful recanalization, there were no significant differences in blood pressure proliles between the good prognosis subgroup and poor prognosis subgroup ( P>0.05). Conclusion:The blood pressure variability 24 h after EVT is correlated with the clinical prognoses of patients with ALVOS of anterior circulation 90 d after EVT.
