Abstract Purpose of Review In this review article we will discuss the acute hypertensive response in the context of acute ischemic stroke and present the latest evidence-based concepts of the significance and management of the hemodynamic response in acute ischemic stroke. Recent Findings Acute hypertensive response is considered a common hemodynamic physiologic response in the early setting of an acute ischemic stroke. The significance of the acute hypertensive response is not entirely well understood. However, in certain types of acute ischemic strokes, the systemic elevation of the blood pressure helps to maintain the collateral blood flow in the penumbral ischemic tissue. The magnitude of the elevation of the systemic blood pressure that contributes to the maintenance of the collateral flow is not well established. The overcorrection of this physiologic hemodynamic response before an effective vessel recanalization takes place can carry a negative impact in the final clinical outcome. The significance of the persistence of the acute hypertensive response after an effective vessel recanalization is poorly understood, and it may negatively affect the final outcome due to reperfusion injury. Summary Acute hypertensive response is considered a common hemodynamic reaction of the cardiovascular system in the context of an acute ischemic stroke. The reaction is particularly common in acute brain embolic occlusion of large intracranial vessels. Its early management before, during, and immediately after arterial reperfusion has a repercussion in the final fate of the ischemic tissue and the clinical outcome.

Background: Blood pressure variability (BPV) is associated with target organ damage progression and increased cardiovascular events, including stroke. The aim of this study was to evaluate the associations between short-term BPV during acute periods and recanalization degree, early neurological deterioration (END) occurrence, and functional outcomes in acute ischemic stroke patients who had undergone intra-arterial thrombectomy (IAT). Methods: We retrospectively analyzed 303 patients with large vessel occlusive stroke who underwent IAT. The following BPV parameters, measured over 24 and 48 h after IAT, were compared: the mean, SD, coefficient of variation (CV), variation independent of the mean (VIM) for both the systolic BP (SBP) and diastolic BP, and the proportion of nocturnal SBP risers. Results: BPV parameters decreased with higher recanalization degree. The mean SBP (SBPmean) over 24 and 48 h after IAT, and the SD of SBP (SBPSD), CV of SBP (SBPCV), and VIM of SBP (SBPVIM) during the 48 h following the procedure had significant associations with recanalization degree. Patients with END had higher BPV than that of those without END, and the difference was more evident for incomplete recanalization. Increased BPV was associated with a shift toward poor functional outcome at 3 months after adjustment, including recanalization degree (OR range for significant parameters, 1.26–1.64, p = 0.006 for 48 h SBPmean, p = 0.003 for 48 h SBPCV, otherwise p < 0.002). Conclusions: Short-term BPV over 24 and 48 h after IAT in acute ischemic stroke patients was related to recanalization degree, and END occurrence, and may be an independent predictor of clinical outcome.

ABSTRACT:Objectives:The association between blood pressure (BP) and short-term clinical outcome of acute ischemic stroke is inconclusive. We investigated the association between BP in the first 72 hours following admission and death in-hospital and neurologic deficiency at discharge among patients with acute ischemic stroke.Methods:A total of 2675 acute ischemic stroke patients confirmed by a computed tomography scan or magnetic resonance imaging were included in the present study. Blood pressure in the first 72 hours after admission and other study variables were collected for all ischemic stroke patients. Neurological functions National Institute of Health Stroke Scale (NIHSS) were evaluated by trained neurologists at discharge. The study outcome was defined as death in-hospital and neurologic deficiency (NIHSS≥10) at discharge.Results:Systolic and diastolic BP were significantly and positively associated with odds of study outcome in acute ischemic stroke. For example, compared to those with a systolic BP<140 mmHg, multiple-adjusted odds ratio (95% confidence interval) of study outcome was 3.29(1.22, 8.90) among participants with systolic BP of 180-219 mmHg,P<0.05; compared to those with a diastolic BP<90 mmHg, multiple-adjusted odds ratio of study outcome was 7.05(1.32, 37.57) among participants with diastolic BP ≥ 120 mmHg,P<0.05.Conclusion:Systolic BP≥180 and diastolic BP≥120 were significantly and positively associated with death in-hospital or neurologic deficiency at discharge among patients with acute ischemic stroke.
