Abstract
CONTEXT Stroke is one of the largest healthcare burdens in the United States and globally. It continues to be one of the leading causes of morbidity and mortality. Patients with acute ischemic stroke (AIS) often present with elevated blood pressure (BP). OBJECTIVES The objective of our study was to evaluate the association of systolic blood pressure (SBP) in the emergency department (ED) with stroke severity in patients with AIS. METHODS This observational study was conducted at an ED with an annual census of 80,000 visits, approximately half (400) of which are for AIS. The cohort consisted of adult patients who presented to the ED within 24 h of stroke symptom onset. BP was measured at triage by a nurse blinded to the study. Stroke severity was measured utilizing the National Institutes of Health Stroke Scale (NIHSS). Statistical analyses were performed utilizing JMP 14.0. This study was approved by our medical school's institutional review board. RESULTS Patients with higher SBP had significantly lower NIHSS scores (p=0.0038). This association was significant even after adjusting for age and gender. By contrast, diastolic blood pressure (DBP) did not appear to impact stroke severity. There was no difference in the DBP values between men and women. Higher SBP was also significantly associated with being discharged home as well as being less likely to die in the hospital or discharged to hospice. The DBP did not demonstrate this association. Neither the SDP nor the DBP were significantly associated with the hospital length of stay (LOS). In multivariate models that included age, gender, basal metabolic index (BMI), comorbidities, and ED presentation, elevated SBP was associated with better prognosis. CONCLUSIONS In this cohort of patients presenting with stroke-like symptoms to the ED, higher SBP was associated with lower stroke severity and higher rates of being discharged to home rather than hospice or death.

Abstract
Objective: The aim of this study was to investigate the clinical characteristics and factors associated with pediatric hypertension and target organ damage (TOD). Methods: We retrospectively reviewed clinical data from 205 children with hypertension treated in our hospital from 2007 to 2018. The patients were classified based on the type of hypertension (primary, secondary) and presence of TOD (heart, brain, retina). Logistic regression analysis was performed to identify the factors independently associated with hypertension and TOD. Results: There were 107 males, 97 females, and one intersex in this study, with an age range of 0.1-17.9 years. Majority of cases (177, 86.3%) had secondary hypertension, while 13.7% had primary hypertension. The most frequent cause of secondary hypertension was renal disease (59.32%). Elevated serum creatinine level (odds ratio [OR] = 7.22, 95% confidence interval [95% CI] = 1.6-32.62, P = 0.01), blood urea nitrogen (OR = 6.33, 95% CI = 1.81-22.19, P = 0.004), serum uric acid level (OR = 3.66, 95% CI = 1.20-11.22, P = 0.023), and albuminuria (OR = 3.72, 95% CI = 1.50-9.26, P = 0.005) were independently associated with secondary hypertension. Elevated serum uric acid and blood urea nitrogen levels were associated with left ventricular hypertrophy (OR = 6.638, 95% CI = 1.349-32.657, P = 0.02) and hypertensive encephalopathy (OR = 4.384, 95% CI = 1.148-16.746, P = 0.031), respectively. Triglyceride level correlated with hypertensive retinopathy (P = 0.001). Conclusion: Pediatric hypertension was most often secondary, with renal disease as the leading cause. Elevated levels of serum uric acid, blood urea nitrogen, serum creatinine, and albuminuria may indicate secondary hypertension in childhood. Elevated serum uric acid, blood urea nitrogen, and triglyceride levels were associated with left ventricular hypertrophy, hypertensive encephalopathy, and hypertensive retinopathy, respectively.

Abstract
BACKGROUND Telemedicine rapidly connects patients, with acute ischemic stroke symptoms, with neurovascular specialists for assessment to reduce chemical thrombolysis delivery times. Management of AIS includes maintaining target systolic blood pressures (SBP). In this retrospective study, we assess the efficacy of the telestroke (TS) system at a primary stroke center and the prognostic value of SBP throughout the transportation process. METHODS Patients presenting with acute-onset neurological symptoms to the TS hospitals network, over a 5-year period, were assessed. Those with a confirmed diagnosis of AIS were included. We examined demographics, presenting-NIHSS, last SBP before transfer from the network hospital and continuous BP during transport, stroke risk factors, hospital-course, door-to-needle (DTN) time, treatments, and modified Rankin Scale(mRS). Multivariate analysis was conducted to evaluate the prognostic value of SBP on stroke outcome. RESULTS Of 2,928 patients identified, 1,353 were diagnosed with AIS. Mean age was 66.6 years (SD = 15.4), 47.6% female. Most cases affected the MCA(44.5%). Mean presenting-NIHSS was 8.67(SD = 8.38) and mean SBP was 148 mmHg(SD = 25.39). 73.2% treated using a standard protocol, 23.7% given IVrt-PA, and 6.8% received mechanical thrombectomy(MT). Mean DTN was 96 min(SD = 46; 27.3% <60 min). Age, presenting-NIHSS and pre-existing hypertension were associated with higher mortality and/or higher mRS. SBP was not associated with higher mortality and morbidity. CONCLUSIONS This study displays better clinical outcomes at latest follow-up when compared to current international TS studies. SBP during transportation to the hub hospital did not prove to be a useful prognostic metric. However, future studies should address the limitations of this study to confirm these findings.

Abstract
We demonstrate the safety of artificially elevating the mean arterial blood pressure (MAP) greater than 85 mmHg or 10% above the mean MAP in patients with underlying hypertension during the acute post-operative period in patients undergoing surgery for resection of brain tumors. A retrospective review was undertaken of all patients undergoing surgery by the senior author between 2013 and 2018. Patients who underwent MAP therapy were analyzed for hemorrhagic and cardiac complications. A total of 1162 of 2270 post-operative brain tumor patients underwent MAP therapy after surgery for a minimum of 24 h post-operatively. Of these, 7/1162 (0.6%) patients experienced intra-cavitary hemorrhage within 5 days of surgery. Two of 7 (29%) patients were diagnosed with venous infarction. One of 7 (14%) patients experienced post-operative, intra-cavitary hemorrhage prior to the initiation of MAP therapy. The remaining 4/1162 (0.35%) patients experienced intra-cavitary hemorrhage post-operatively without clear etiology. In assessing cardiac outcomes, 2/1162 patients (0.2%) experienced elevated troponin levels. No patient demonstrated significant cardiac related morbidity or mortality within this cohort. Post-operative MAP therapy with a goal of maintaining MAP greater than 85 mmHg or 10% above the mean MAP in patients with underlying hypertension appears to be a safe intervention in brain tumor patients for at least 24 h in the post-operative period.

Abstract
Objective To assess relationships between blood pressure hemodynamic measures and outcomes after acute ischemic stroke, including stroke severity, disability and death. Methods The study cohort consisted of 189 patients who presented to our emergency department with ischemic stroke of less than 24 hours onset who had hemodynamic parameters recorded and available for review. Blood pressure (BP) was non-invasively measured at 5 minute intervals for the length of the patient's emergency department stay. Systolic BP (sBP) and diastolic BP (dBP) were measured for each patient and a differential (the maximum minus the minimum BP) calculated. Three outcomes were studied: stroke severity, disability at hospital discharge, and death at 90 days. Statistical tests used included Spearman correlations (for stroke severity), Wilcoxon test (for disability) and Cox models (for death). Results Larger differentials of either dBP (p = 0.003) or sBP (p < 0.001) were significantly associated with more severe strokes. A greater dBP (p = 0.019) or sBP (p = 0.036) differential was associated with a significantly worse functional outcome at hospital discharge. Those patients with larger differentials of either dBP (p = 0.008) or sBP (0.007) were also significantly more likely to be dead at 90 days, independently of the basal BP. Conclusion A large differential in either systolic or diastolic blood pressure within 24 hours of symptom onset in acute ischemic stroke appears to be associated with more severe strokes, worse functional outcome and early death

Abstract
Introduction. Acute and severe hypertension is common,
especially in patients with renal dysfunction (RD). Clevidipine is a rapidly
acting (t½∼1 min) intravenous (IV)
dihydropyridine calcium-channel blocker metabolized by blood and tissue
esterases and may be useful in patients with RD. The purpose of this analysis
was to assess the safety and efficacy of clevidipine in patients with RD.
Methods. VELOCITY, a multicenter open-label study of severe
hypertension, enrolled 126 patients with persistent systolic blood pressure
(SBP) >180 mmHg. Investigators pre-specified a SBP initial target range
(ITR) for each patient to be achieved within 30 min. Blood pressure monitoring
was by cuff. Clevidipine was infused via peripheral IV at 2 mg/h for at least 3
min, then doubled every 3 min as needed to a maximum of 32 mg/h (non-weightbased
treat-to-target protocol). Per protocol, clevidipine was continued for at least
18 h (96 h maximum). RD was diagnosed and reported as an end-organ injury by the
investigator and was defined as requiring dialysis or an initial creatinine
>2.0 mg/dl. Primary endpoints were the percentage of patients within the
ITR by 30 min and the percentage below the ITR after 3 min of clevidipine
infusion. Results. Of the 24 patients with moderate to severe
RD, most (13/24) were dialysis dependent. Forty-six percent were male, with mean
age 51 >14 years; 63% were black and 96% had a hypertension history.
Median time to achieve the ITR was 8.5 min. Almost 90% of patients reached the
ITR in 30 min without evidence of overshoot and were maintained on clevidipine
through 18 h. Most patients (88%) transitioned to oral antihypertensive therapy
within 6 h of clevidipine termination. Conclusions. This report
is the first demonstrating that clevidipine is safe and effective in RD
complicated by severe hypertension. Prolonged infusion maintained blood pressure
within a target range and allowed successful transition to oral therapy.

Abstract
Acute severe hypertension occurs in approximately 50% of patients with acute heart failure (AHF). Clevidipine, the latest-generation dihydropyridine calcium channel blocker, may be useful in the treatment of this patient population. The Evaluation of the Effect of Ultra-Short-Acting Clevidipine in the Treatment of Patients With Severe Hypertension (VELOCITY) trial enrolled 126 patients with systolic blood pressure (SBP) >180 mm Hg for treatment with clevidipine to a patient-specific prespecified initial target range (ITR) of SBP to be achieved within 30 minutes. Of the enrolled patients, 19 had AHF on presentation. Primary end points were the percentage in whom ITR was achieved within 30 minutes and the number whose SBP was below the ITR after 3 minutes of clevidipine infusion. Among the 19 AHF patients in VELOCITY, median time to ITR was 11.3 minutes (95% confidence interval, 7-19). ITR was reached in most patients (94%) within 30 minutes. No patient had hypotension below the ITR, and heart rate remained stable. At 18 hours, 16 of 19 patients had received continuous clevidipine infusion, and their SBP was reduced by mean of 50 mm Hg (25%) from baseline. There were no treatment-related adverse events or adverse events that led to clevidipine discontinuation. Clevidipine safely decreases SBP in AHF and does not cause unexpected hypotension. The results of this post hoc subgroup analysis suggest that clevidipine is safe, well tolerated, and efficacious in AHF patients with hypertension.

Abstract
Clevidipine is a new calcium channel blocker of the dihydropyridine class that is characterized by its ultra-short onset of action, vascular selectivity, small volume of distribution and extremely high clearance that coupled together result in an extremely short half-life of approximately 1 minute therefore permitting a rapid titration to the desired effect. Structurally similar to other dihydropyridines, clevidipine has an extra ester link that allows its rapid hydrolization to its inactive carboxylic acid metabolite in blood and extravascular tissues. Clevidipine’s metabolites are then primarily eliminated through urine and fecal pathways. Clevidipine does not affect cytochrome P450 (CYP) enzymes and no clinically significant drug interactions have been determined. In trials like the ESCAPE trials, ECLIPSE, and VELOCITY, clevidipine demonstrated a significant improvement in the management of acute hypertension when compared to placebo as shown in both ESCAPE trials. The ECLIPSE trial compared clevidipine to other drugs currently used in the management of acute hypertension, such as sodium nitroprusside, nitroglycerine and nicardipine; clevidipine was superior to all three agents; in providing blood pressure support, safety and tolerability clevidipine also showed a significant reduction in mortality rate (4.7% vs 1.7%, P =0.0445) when compared to sodium nitroprusside. In the VELOCITY trial clevidipine demonstrated a reduction in blood pressure of 6% at the 3 minute mark, 15% within 9.5 minutes and 27% at the 18 hour mark.

Abstract
Hypertension management is a common reason for visits to primary care physicians. One third of patients with hypertension do not have controlled blood pressure, and may present to the physician's office with hypertensive urgencies or emergencies. How to define severely elevated blood pressure, appropriate triage, and the clinical evaluation of those with hypertensive urgencies or emergencies is reviewed. Suggestions for pharmacologic therapy and follow-up are offered.
