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: Increased blood pressure variability (BPV) is detrimental in the weeks to months after ischemic stroke, but it has not been adequately studied in the acute phase. We hypothesized that increased BPV in acute ischemic stroke (AIS) patients would be associated with worse outcome. Methods: We retrospectively reviewed inpatients at our hospital between 2010-2014 with an ICD-9 code of AIS; 213 were confirmed to have AIS by a vascular neurologist. A modified Rankin Score (mRS) after discharge was available in 148/213, at a mean of 86 ± 60 days. In 45/213 the discharge mRS was either 0 or 6, in which case they were included in the final analysis. BPV was measured as the standard deviation (SD) of each patient’s systolic blood pressure readings during the first 24 hours and 5 days of hospitalization (9,844 total readings), or until discharge if discharged in <5 days (Figure 1). The SBP SD was further divided in quartiles. A multivariate ordinal logistic regression with the outcome of mRS, the primary predictor of quartiles of SBP SD, and baseline NIH stroke scale (NIHSS) to control for initial stroke severity. Results: Mean±SD age was 64.2 ± 16.3 years, NIHSS was 12.6 ± 7.9, and mRS was 2.7 ± 2.1. The mean SBP SDs for the first 24 hours and 5 days were 12.1 ± 6.2 mm Hg and 14.1 ± 4.9 mm Hg. In the ordinal logistic regression model, the quartiles of SBP SD for the first 24 hours and 5 days were positively associated with higher mRS (OR = 1.37, 95% CI 1.01 - 1.74, p = 0.009; OR = 1.30, 95% CI 1.03 - 1.63, p = 0.028). This effect became even more pronounced in patients with the highest quartile of variability (OR = 2.76, 95% CI 1.29 - 5.88, p = 0.009; OR = 2.10, 95% CI 1.01 - 4.36, p = 0.046). Conclusion: In our cohort of 193 patients with AIS, there was a significant association between increased systolic BPV and worse functional outcome, after controlling for initial stroke severity. This data suggests that increased BPV may have a harmful effect for AIS patients, which warrants a prospective observational study.

Background: Per American Heart Association guidelines, blood pressure (BP) should be < 185/110 to be eligible for intravenous tissue plasminogen activator (tPA). It is shown that door to needle (DTN) time is prolonged in patients who require anti-hypertensive medications prior to thrombolysis in the emergency department (ED). To our knowledge, no studies have focused on pre-hospital BP and its impact on DTN times. We hypothesize that DTN times are longer for patients with higher pre-hospital BP. Methods: We conducted a retrospective review of acute ischemic stroke patients who presented between 1/2010 and 12/2010 to our ED through Emergency Medical Services (EMS) within 3-hrs of symptom onset. Patients were identified from our registry and categorized into two groups: Pre-hospital BP ≥ 185/110 (Pre-hsp HBP) and < 185/110 (Pre-hsp LBP). BP records were abstracted from EMS sheets. Two groups were compared using two-sample t-test or Wilcoxon rank sum test for continuous variables and Chi-square test or Fisher’s exact test for categorical variables. Results: A total of 107 consecutive patients were identified. Out of these, 75 patients (70%) were treated with tPA. Among the patients who received thrombolysis, 35% had pre-hospital BP ≥ 185/110 (n= 26/75). Greater number of patients required anti-hypertensive medications in ED in high BP group compared to low BP group (Pre-hsp HBP n= 14/26, 54%; Pre-hsp LBP n= 13/49, 27%, p < 0.02). Mean door to needle times were significantly higher in Pre-hsp HBP group. (mean ± SD 87.5± 34.2 Vs. 59.7±18.3, p<0.0001). Analysis of patients only within the Pre-hsp HBP group (n= 26) revealed that DTN times were shorter if patients received pre-hsp BP medications compared to patients in the same group who did not receive pre-hsp BP medication (n= 10 vs 16; mean ± SD 76.5 ± 25.7 Vs. 94.3 ± 37.7, p = 0.20) Conclusion: Higher pre-hospital BP is associated with prolonged DTN times and it stays prolonged if pre-hospital high BP remains untreated. Although the later finding was not statistical significant due to small sample size, pre-hospital blood pressure control could be a potential area for improvement to reduce door to needle times in acute ischemic stroke.
