Hypertension is a Leading Cause of Nontraumatic Intracerebral Hemorrhage in Young Adults.

OBJECTIVE: To evaluate the etiology and discharge outcome of nontraumatic intracerebral hemorrhage (ICH) in young adults admitted to a comprehensive stroke center. METHODS: A retrospective chart review was performed on patients with a discharge diagnosis of nontraumatic ICH admitted from 7/1/2011 to 6/30/2016. Data was collected on demographics, clinical history, ICH score, hemorrhage location, do-not-resuscitate (DNR) orders, likely etiology, and discharge disposition. Categorical data was reported as percentage. Chi-squared test was performed to evaluate association of location of ICH, etiology of ICH, and ICH score with the discharge outcome. RESULTS: Sixty-three patients met the study criteria, with mean age 35.4 ± 6.4 years including 26 (41%) women and 40 (64%) whites. Headache (65%) and change in mental status (48%) were the most common presenting symptoms. Hemorrhage was most commonly seen in the deep structures in 29 (46%) patients followed by lobar ICH in 14 (22%) patients. The most common etiology of ICH was hypertension in 23 (37%) patients, followed by vascular abnormalities in 18 (29%) patients. Forty-two (67%) had good outcome defined as discharge to home (n = 25) or acute inpatient rehabilitation (n = 17). Twenty-one (33%) patients had bad outcome with discharge to skilled nursing facility (n = 6), hospice (n = 1) or died in the hospital (n = 14). Hospital DNR orders were noted in 11 (18%) patients. Higher ICH score (P < .0001) and use of DNR orders (P < .0001) were associated with bad outcome. All 11 patients with DNR orders died in the hospital. Location or etiology of hemorrhage were not associated with discharge outcome. CONCLUSIONS: Hypertension, a modifiable risk factor, is a major cause of nontraumatic ICH in young adults. Aggressive management of hypertension is essential to halt the recent increased trends of ICH due to hypertension. Early DNR orders may need to be cautiously used in the hospital.

Stereotactic aspiration for hypertensive intracerebral haemorrhage in a Chinese population: a retrospective cohort study.

Objective: We aimed to compare the therapeutic effects of stereotactic aspiration and best medical management in patients who developed supratentorial hypertensive intracerebral haemorrhage (HICH) with a volume of haemorrhage between 20 and 40 mL. Methods: The clinical data of 220 patients with supratentorial HICH with a volume between 20 and 40 mL were retrospectively analysed. Among them, 142 received stereotactic aspiration surgery (stereotactic aspiration group) and 78 received best medical management (conservative group). All were followed up for 6 months. Multivariate logistic regression and Kaplan-Meier survival curves were used to compare the outcome between the two groups. Results: The rebleeding rate was lower in the group that had stereotactic aspiration when compared with the group with medical treatment (6 [4.2%] vs 9 [11.5%], χ2=4.364, p=0.037). After 6 months, although the mortality rate did not differ significantly between the two groups (8 cases [5.6%] vs 10 cases [12.8%], χ2=3.461, p=0.063), the rate of a favourable outcome was higher in the group who received stereotactic aspiration (χ2=15.870, p=0.000). Logistic regression identified that medical treatment (OR=1.64, p=0.000) was an independent risk factor for an unfavourable outcome. The Kaplan-Meier curves indicated that the median favourable outcome time in the stereotactic aspiration group was 59.5 days compared with that in the medically treated group (87.0 days). The log-rank test indicated that the prognosis at 6 months was better for those treated with stereotactic haematoma aspiration (χ2=29.866, p=0.000). However, the 6-month survival rate was similar between the two groups (χ2=3.253, p=0.068). Conclusions: Stereotactic haematoma aspiration significantly improved the quality of life, although did not effectively reduce the rate of mortality. When selected appropriately, patients with HICH may benefit from this type of surgical intervention.

Determinants of Early Versus Delayed Neurological Deterioration in Intracerebral Hemorrhage.

Background and Purpose- We investigated factors associated with early and delayed neurological deterioration (END and DND, respectively) after acute spontaneous intracerebral hemorrhage in the main INTERACT (Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial)-2. Methods- INTERACT-2 was a randomized trial of early intensive versus guideline-recommended blood pressure lowering in hypertensive intracerebral hemorrhage (<6 hours from symptom onset) patients. END and DND were defined as a ≥4-point increase on the National Institutes of Health Stroke Scale or ≥2-point decrease on Glasgow Coma Scale, in periods baseline to 24 hours and 24 hours to 7 days, respectively. Multivariable logistic regression models were used to determine independent predictors of END and DND and 90-day outcomes (death and dependency on the modified Rankin Scale). Results- Of 2598 participants, 450 (17.3%) had either END or DND. Non-China recruitment, higher systolic blood pressure, larger baseline hematoma volume, left hemisphere hematoma location, intraventricular hemorrhage, subarachnoid extension, heterogeneous hematoma density, and cerebral white matter lesions, were predictors of END (all P≤0.045). Higher systolic blood pressure, lower diastolic blood pressure, higher glucose, larger baseline hematoma volume, intraventricular hemorrhage, lobar location, brain atrophy, and heterogeneous hematoma density were predictors of DND (all P≤0.042). END and DND were both related to death, and death or major disability (modified Rankin Scale scores of 3-6), in adjusted analyses ( P<0.001). Conclusions- Common variables, most directly related to the intracerebral hemorrhage morphology and underlying cerebral features, determine END and DND and their influence on poor outcomes of death and major disability.

Serum calcium levels at admission is associated with the outcomes in patients with hypertensive intracerebral hemorrhage.

BACKGROUND/OBJECTIVE: Hypertensive spontaneous intracerebral hemorrhages (ICH) cause significant morbidity and mortality. In this study, we aimed to investigate the association between calcium level at admission and outcome in hypertensive ICH patients. METHODS: 658 hypertensive ICH patients were enrolled from January 2012 to January 2016 in this retrospective study, and demographic, clinical, laboratory, radiographic, and outcome data were collected. The associations between serum calcium level and initial hematoma volume, hematoma enlargement and functional outcome were assessed. RESULTS: Lower calcium level at admission was associated with larger initial hematoma volumes, baseline NIHSS and mRSscore (p < .05), but not with platelet count, activated partial thromboplastin time and international normalized ratio on admission (p > .05). For outcome assessment, 30 days mortality and 6 months mRS were adjusted for age, gender and time from onset to admission, cigarette smoking, alcohol drinking, history of hypertension, baseline NIHSS score, Baseline mRS score and hematoma position, lower calcium level at admission was associated with worse outcomes. CONCLUSION: Low calcium level at admission is associated with worse outcome and might be a prognostic factor for acute ICH.

Development and validation of the hypertensive intracerebral hemorrhage prognosis models.

To develop and validate the prognosis model of hypertensive intracerebral hemorrhage based on admission characteristics, which would be applied to predict the 3-month outcome.For developing the prognosis models, we studied data from 325 patients with retrospectively consecutive hypertensive intracerebral hemorrhage admitted between 2012 and 2016. The predictive value of admission characteristics was tested in logistic regression models, presenting 3-month outcome as the primary outcome. The performance of the models was tested by discrimination and calibration. After development, internal and external validations were used to test the function.The multivariate analysis of logistic regression indicated that age, Glasgow coma scale score, pupillary light reflex, hypoxemia, intracerebral hemorrhage volume, blood glucose, and D-dimer level were independent factors of the hypertensive intracerebral hemorrhage prognosis model. The prognosis model based on those admission risk factors worked well. The receiver operating characteristic curve was used to analyze the discriminant ability of model A, model A + B, and model A + B + C. Specifically, the area under the receiver operating characteristic curve increased from 0.816 (model A; 95% CI, 0.760-0.872) to 0.913 (model A + B + C; 95% CI, 0.881-0.946), and the models were not overoptimistic and were applicably confirmed by internal and external validations respectively.This prognosis model could be used to predict the prognosis of patients with hypertensive intracerebral hemorrhage early, simply and accurately, contributing to the clinical treatment eventually.

The "Blush" Sign on Computed Tomography Angiography is an Independent Predictor of Hematoma Progression in Primary Hypertensive Hemorrhage.

BACKGROUND AND PURPOSE: Hypertension is an important etiology of intracerebral hemorrhage (ICH) in neurosurgical practice. Contrast extravasation on computed tomography angiography, known as the "spot sign", has been described as an independent predictor of hematoma progression and clinical deterioration. However, its role in hypertensive ICH alone has not been determined and is the primary aim of this study. MATERIALS AND METHODS: A retrospective review was carried out of patients with hypertensive ICH admitted to our institution between May 2014 and December 2016. Evaluation of the neuroimaging studies of these patients revealed two distinct morphologies, "spot" and "blush" sign. These distinct signs and covariates were tested for association with hematoma expansion and mortality using multivariate logistic regression. The accuracy of the "spot" and "blush" signs as predictors of hematoma expansion and mortality was determined using receiver-operator characteristic (ROC) analysis. RESULTS: A total of 54 patients were identified as hypertensive ICH during the study period. "spot" sign was observed in 11 (20.4%) of the study population. Contrast extravasation (blush-sign) was seen in 7 (14.8%) patients. The "blush" was an independent predictor of hematoma expansion (odds ratio [OR] 6.052; confidence interval [CI] 1.036-15.945 [P = .012]) and mortality (OR 3.305; CI 1.240-25.414 [P = .032]). With ROC analysis, the "blush" sign was found to have a better predictive value for significant hematoma expansion (area under the curve [AUC]: .795) than the spot sign (AUC: .432). CONCLUSION: The "blush" sign has better accuracy for predicting hematoma expansion in hypertensive ICH and could be used to risk stratify these patients for early therapeutic interventions.

Influence of Bleeding Pattern on Ischemic Lesions After Spontaneous Hypertensive Intracerebral Hemorrhage with Intraventricular Hemorrhage.

BACKGROUND: Concomitant acute ischemic lesions are detected in up to a quarter of patients with spontaneous intracerebral hemorrhage (ICH). Influence of bleeding pattern and intraventricular hemorrhage (IVH) on risk of ischemic lesions has not been investigated. METHODS: Retrospective study of all 500 patients enrolled in the CLEAR III randomized controlled trial of thrombolytic removal of obstructive IVH using external ventricular drainage. The primary outcome measure was radiologically confirmed ischemic lesions, as reported by the Safety Event Committee and confirmed by two neurologists. We assessed predictors of ischemic lesions including analysis of bleeding patterns (ICH, IVH and subarachnoid hemorrhage) on computed tomography scans (CT). Secondary outcomes were blinded assessment of mortality and modified Rankin scale (mRS) at 30 and 180 days. RESULTS: Ischemic lesions occurred in 23 (4.6%) during first 30 days after ICH. Independent risk factors associated with ischemic lesions in logistic regression models adjusted for confounders were higher IVH volume (p = 0.004) and persistent subarachnoid hemorrhage on CT scan (p = 0.03). Patients with initial IVH volume ≥ 15 ml had five times the odds of concomitant ischemic lesions compared to IVH volume < 15 ml. Patients with ischemic lesions had significantly higher odds of death at 1 and 6 months (but not poor outcome; mRS 4-6) compared to patients without concurrent ischemic lesions. CONCLUSIONS: Occurrence of ischemic lesions in the acute phase of IVH is not uncommon and is significantly associated with increased early and late mortality. Extra-parenchymal blood (larger IVH and visible subarachnoid hemorrhage) is a strong predictor for development of concomitant ischemic lesions after ICH.

Current management of spontaneous intracerebral haemorrhage.

Intracerebral haemorrhage (ICH) is the most devastating and disabling type of stroke. Uncontrolled hypertension (HTN) is the most common cause of spontaneous ICH. Recent advances in neuroimaging, organised stroke care, dedicated Neuro-ICUs, medical and surgical management have improved the management of ICH. Early airway protection, control of malignant HTN, urgent reversal of coagulopathy and surgical intervention may increase the chance of survival for patients with severe ICH. Intensive lowering of systolic blood pressure to <140 mm Hg is proven safe by two recent randomised trials. Transfusion of platelets in patients on antiplatelet therapy is not indicated unless the patient is scheduled for surgical evacuation of haematoma. In patients with small haematoma without significant mass effect, there is no indication for routine use of mannitol or hypertonic saline (HTS). However, for patients with large ICH (volume > 30 cbic centmetre) or symptomatic perihaematoma oedema, it may be beneficial to keep serum sodium level at 140-150 mEq/L for 7-10 days to minimise oedema expansion and mass effect. Mannitol and HTS can be used emergently for worsening cerebral oedema, elevated intracranial pressure (ICP) or pending herniation. HTS should be administered via central line as continuous infusion (3%) or bolus (23.4%). Ventriculostomy is indicated for patients with severe intraventricular haemorrhage, hydrocephalus or elevated ICP. Patients with large cerebellar or temporal ICH may benefit from emergent haematoma evacuation. It is important to start intermittent pneumatic compression devices at the time of admission and subcutaneous unfractionated heparin in stable patients within 48 hours of admission for prophylaxis of venous thromboembolism. There is no benefit for seizure prophylaxis or aggressive management of fever or hyperglycaemia. Early aggressive comprehensive care may improve survival and functional recovery.

Joint Effects of GWAS SNPs in Coagulation System Confer Risk to Hypertensive Intracerebral Hemorrhage.

Recent genome-wide association studies (GWAS) have identified numerous single nucleotide polymorphisms (SNPs) associated with coagulation system, including hemostatic factors and hematological phenotypes. However, few articles described the relationships between these SNPs and the risk of hemorrhagic stroke. The aim of our study was to evaluate the roles of these SNPs as risk factors and survival predictors for hemorrhagic stroke. Thirteen SNPs from GWAS in coagulation system were genotyped in a Chinese Han population including 1000 patients with hemorrhagic stroke (intracerebral hemorrhage, ICH = 743; subarachnoid hemorrhage, SAH = 257) and 1044 population-based controls. The associations between the genetics risk score (GRS) and risk of hemorrhagic stroke as well as post-stroke adverse outcomes were determined. No individual SNP was associated with the risk of hemorrhagic stroke. The GRS was calculated by summing the number of risk alleles of each SNP, and a total of 13 SNPs were included. Meanwhile, the GRS cutoffs values were defined to be close to quartiles or tertiles in control subjects. For quartiles, individuals with GRS about 8-9, 10-11, ≥12 had 1.28 (OR 1.28, 95% CI 0.98-1.68, p = 0.067)-, 1.36 (OR 1.36, 95% CI 1.04-1.79, p = 0.026)-, 1.53 (OR 1.53, 95% CI 1.13-2.07, p = 0.006)-fold increase in ICH risk compared to those with GRS ≤7, respectively; for tertiles, individuals with GRS about GRS 9-10, ≥11 had 0.98 (OR 0.98, 95% CI 0.78-1.23, p = 0.067)- and 1.26 (OR 1.26, 95% CI 1.00-1.59, p = 0.048)-fold increase in ICH risk compared to those with GRS ≤8, respectively. Further stratification analyses indicated that this association was only found in hypertensive ICH subjects. However, no statistical difference was found in the volume of hematoma, activities of daily living scale as well as hospital death in the ICH patients based on GRS values. Joint effects of SNPs associated with low coagulation factor levels might confer risk to ICH patients with hypertension. However, the clinical value on risk stratification and survival prediction was limited.

Comparison of endoscopic evacuation, stereotactic aspiration and craniotomy for the treatment of supratentorial hypertensive intracerebral haemorrhage: study protocol for a randomised controlled trial.

BACKGROUND: Hypertensive intracerebral haemorrhage (HICH) is the most common form of haemorrhagic stroke with the highest morbidity and mortality of all stroke types. The choice of surgical or conservative treatment for patients with HICH remains controversial. In recent years, minimally invasive surgeries, such as endoscopic evacuation and stereotactic aspiration, have been attempted for haematoma removal and offer promise. However, research evidence on the benefits of endoscopic evacuation or stereotactic aspiration is still insufficient. METHODS/DESIGN: A multicentre, randomised controlled trial will be conducted to compare the efficacy of endoscopic evacuation, stereotactic aspiration and craniotomy in the treatment of supratentorial HICH. About 1350 eligible patients from 10 neurosurgical centres will be randomly assigned to an endoscopic group, a stereotactic group and a craniotomy group at a 1:1:1 ratio. Randomisation is undertaken using a 24-h randomisation service accessed by telephone or the Internet. All patients will receive the corresponding surgery based on their grouping. They will be followed-up at 1, 3 and 6 months after surgery. The primary outcome is the modified Rankin Scale at 6-month follow-up. Secondary outcomes include: haematoma clearance rate; Glasgow Coma Scale 7 days after surgery; rebleeding rate; intracranial infection rate; hospitalisation time; mortality at 1 month and 3 months after surgery; the Barthel Index and the WHO quality of life at 3 months and 6 months after surgery. DISCUSSION: The trial aims to investigate whether endoscopic evacuation and stereotactic aspiration could improve the outcome of supratentorial HICH compared with craniotomy. The trial will help to determine the best surgical method for the treatment of supratentorial HICH. TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT02811614 . Registered on 20 June 2016.

Effect of integrated traditional Chinese and Western medicine therapy for acute hypertensive intracerebral hemorrhage: a meta-analysis.

Intracerebral hemorrhage (ICH) is an important public health problem associated with high mortality and morbidity. The aim of this study was to evaluate the clinical efficacy of integrated traditional Chinese (TCM) and Western medicine (WM) therapy for acute hypertensive ICH. Randomized controlled trials were searched in PubMed, Medline, Embase, Wanfang and CNKI database published between January 2000 and June 2016. Our results showed that integrated TCM and WM therapy appeared to be able to improve the clinical effect for patients with acute hypertensive ICH.

Continuing versus Stopping Prestroke Antihypertensive Therapy in Acute Intracerebral Hemorrhage: A Subgroup Analysis of the Efficacy of Nitric Oxide in Stroke Trial.

BACKGROUND AND PURPOSE: More than 50% of patients with acute intracerebral hemorrhage (ICH) are taking antihypertensive drugs before ictus. Although antihypertensive therapy should be given long term for secondary prevention, whether to continue or stop such treatment during the acute phase of ICH remains unclear, a question that was addressed in the Efficacy of Nitric Oxide in Stroke (ENOS) trial. METHODS: ENOS was an international multicenter, prospective, randomized, blinded endpoint trial. Among 629 patients with ICH and systolic blood pressure between 140 and 220 mmHg, 246 patients who were taking antihypertensive drugs were assigned to continue (n = 119) or to stop (n = 127) taking drugs temporarily for 7 days. The primary outcome was the modified Rankin Score at 90 days. Secondary outcomes included death, length of stay in hospital, discharge destination, activities of daily living, mood, cognition, and quality of life. RESULTS: Blood pressure level (baseline 171/92 mmHg) fell in both groups but was significantly lower at 7 days in those patients assigned to continue antihypertensive drugs (difference 9.4/3.5 mmHg, P < .01). At 90 days, the primary outcome did not differ between the groups; the adjusted common odds ratio (OR) for worse outcome with continue versus stop drugs was .92 (95% confidence interval, .45-1.89; P = .83). There was no difference between the treatment groups for any secondary outcome measure, or rates of death or serious adverse events. CONCLUSIONS: Among patients with acute ICH, immediate continuation of antihypertensive drugs during the first week did not reduce death or major disability in comparison to stopping treatment temporarily.

A prospective study of in-hospital mortality and discharge outcome in spontaneous intracerebral hemorrhage.

BACKGROUND: Intracerebral hemorrhage (ICH) is associated with high mortality and morbidity. Various clinical and imaging predictors of mortality have been observed in previous studies. AIMS: To study factors associated with in-hospital mortality in patients with ICH and observe the disability status of patients [assessed by modified Rankin scale (mRS)] at the time of discharge. DESIGN: Prospective observational study. MATERIALS AND METHODS: All consecutive patients with acute hypertensive ICH admitted during the study period were enrolled. Data recorded included: Demographics, clinical, biochemical and cranial computed tomography (CT) findings. Primary outcome was defined as either death or survival within the hospital. mRS was used to assess outcome at discharge. RESULTS: Of the total 214 patients with ICH (193 supratentorial and 21 infratentorial), 70 (32.7%) patients died during the hospital stay. On bivariate analysis, low Glasgow Coma Scale (GCS) score, ventilatory assistance, higher hematoma volume, midline shift, hydrocephalus and intraventricular hematoma (IVH) were associated with mortality. ICH grading scale (ICH-GS) and ICH scores were higher in patients who died (P < 0.0001). Ninety-five (44.6%) patients underwent a neurosurgical intervention; 66 (45.8%) patients among the survivors compared with 29 (41.4%) among those who died (P = 0.54, Odds Ratio (OR) 0.83, 95% Confidence Interval (CI) 0.46-1.48). Independent predictors of mortality included a higher baseline hematoma volume ( P = 0.04 OR 1.01, 95% CI 1.00-1.02), lower GCS ( P = 0.01 OR 2.57, 95%CI 1.25-5.29), intraventricular extension of hematoma ( P = 0.007 OR 2.66, 95% CI 1.26-5.56) and ventilatory requirement (P < 0.0001 OR 8.34, 95%CI 2.75-25.38). Among survivors (n = 144), most were disabled [mRS 0-3, 7 (4.8%) and mRS 4-5, 137 (95.13%)] at discharge. CONCLUSIONS: Low GCS, higher baseline ICH volume, presence of IVH and need for ventilatory assistance are independent predictors of mortality. Most of the patients at discharge were disabled. Surgery did not improve mortality or outcome.

Relationship between serum leptin levels and clinical outcomes of hypertensive intracerebral hemorrhage.

Circulating leptin is associated with cardiovascular events but the relationship between leptin and the clinical outcomes of intracerebral hemorrhage (ICH) is unclear. This study was to investigate the relationship between circulating leptin and the short-term clinical outcomes of ICH. Fifty-seven patients with hypertensive ICH (stroke group), 50 patients with hypertension (hypertension group), and 41 healthy subjects (control group) were recruited to this study. Serum levels of leptin were measured by radioimmunoassay. The serum level of leptin in the stroke group (14.6 ± 3.3 ng/L) was significantly higher than in the hypertension (10.2 ± 2.9 ng/L, P < 0.05) and control group (4.7 ± 3.3 ng/L, P < 0.01). Nine patients (15.8%) in the stroke group died during hospitalization. The mean National Institute of Health Stroke Scale (NIHSS) score of the surviving patients at admission and before discharge was 16 ± 6 and 9 ± 5, respectively (P < 0.01). There was a significant correlation between the serum leptin level and predischarge NIHSS scores (r = 0.62, P < 0.01). After adjusting age, sex, ICH volume and location, fasting blood glucose, fasting insulin levels, and systolic blood pressure (SBP) multivariate analysis showed that a high leptin level (>10 ng/L) was an independent predictor for in hospital mortality (adjusted risk ratio (RR), 3.6; 95% confidence interval (CI): 1.22-17.62; P = 0.02). In conclusion, serum leptin levels were increased in patients with hypertensive ICH. High leptin levels were associated with a poor functional recovery following ICH.

Risk factors of early death in patients with hypertensive intracerebral hemorrhage during hospitalization.

Hypertensive intracerebral hemorrhage (ICH) is the deadliest, most disabling and least treatable form of acute cerebral accident. A large number of patients die in a short time after the hemorrhage. However, the risk factors of early death in this pattern are still in debate. A case control study of 273 patients with hypertensive ICH admitted to our hospital was carried out. The patients were divided into the death group and survival group according to clinical outcome during hospitalization. Any possible risk factors were assessed using univariate and multivariate analysis. The logistic regression analysis revealed that the following four factors were independently associated with early death: age [odds ratio (OR), 0.966; 95% confidence interval (CI), 0.936-0.997; P=0.0327], GCS score (OR, 1.192; 95% CI, 1.090-1.303; P<0.001) and systolic pressure (OR, 0.939; 95% CI, 0.772-1.142; P<0.001) at admission, and hematoma volume (OR, 0.8000; 95% CI, 0.807-0.959; P=0.0037). Cranial computed tomography imaging is an important examination method to evaluate the clinical outcome. Effective prevention of hypertension and adequate reduction of blood pressure at admission are recommended as the major measures to improve the prognosis of hypertensive ICH.

Meta-analysis of scalp acupuncture for acute hypertensive intracerebral hemorrhage.

OBJECTIVES: Scalp acupuncture (SA) is a commonly used therapeutic approach for primary intracerebral hemorrhage (ICH) in Traditional Chinese Medicine (TCM), but the efficacy and safety of SA therapy are still undetermined. The aim of this study is to systematically evaluate the efficacy and safety of SA therapy for the treatment of acute hypertensive ICH. METHODS: Literature reports with randomized controlled clinical trials and controlled clinical trials on SA therapy for acute hypertensive ICH were searched, and the efficacy and safety of SA therapy were evaluated by using the Cochrane systematic review methods. The primary outcome measures were death or dependency at the end of long-term follow-up (at least 3 months) and adverse events. The secondary outcome measure was neurological deficit improvement at the end of the treatment course. RESULTS: Seven (7) independent trials (230 patients) were included in this study. All trials described the methods of randomization in which four trials had adequate concealment of randomization at the level of grade A, but no trial included sham acupuncture as a control group. None of the trials included "death or dependency" as a primary outcome measure. Four (4) trials contained safety assessments and stated that no adverse event was found, whereas the other three trials did not provide the information about adverse events. By using random effects statistical model, it was found that patients with acute hypertensive ICH who received SA therapy had significantly improved neurological deficit scores (Z = 4.97, p < 0.01). CONCLUSIONS: Although SA therapy is widely used to treat acute hypertensive ICH in TCM, the efficacy and safety of SA therapy remain to be further determined. No evidence is available on whether SA therapy can be used to treat acute ICH according to the primary outcome measure. However, SA therapy appears to be able to improve neurological deficit in patients with acute hypertensive ICH.

Emergency department control of blood pressure in intracerebral hemorrhage.

BACKGROUND: Early treatment of elevated blood pressure (BP) in patients presenting with spontaneous intracerebral hemorrhage (ICH) may decrease hematoma enlargement and lead to better neurologic outcome. STUDY OBJECTIVE: To determine whether early BP control in patients with spontaneous ICH is both feasible and tolerated when initiated in the Emergency Department (ED). METHODS: A single-center, prospective observational study in patients with spontaneous ICH was performed to evaluate a protocol to lower, and maintain for 24 h, the mean arterial pressure (MAP) to a range of 100-110 mm Hg within 120 min of arrival to the ED. An additional goal of placing a functional arterial line within 90 min was specified in our protocol. Hematoma volume, neurologic disability, adverse events, and in-hospital mortality were recorded. RESULTS: A total of 22 patients were enrolled over a 1-year study period. The average time to achieve our target MAP after implementation of our protocol was 123 min (range 19-297 min). The average time to arterial line placement was 84 min (range 36-160 min). Overall, 77% of the patients tolerated the 24-h protocol. The in-hospital mortality rate in this group of patients was 41%. CONCLUSIONS: Adopting a protocol to reduce and maintain the MAP to a target of 100-110 mm Hg within 120 min of ED arrival was safe and well tolerated in patients presenting with spontaneous ICH. If future trials demonstrate a clinical benefit of early BP control in spontaneous ICH, EDs should implement similar protocols.

Hypertension in the elderly: what is the goal blood pressure target and how can this be attained?

For the aging populations of Europe, many emerging health problems in addition to myocardial infarction and stroke are associated with hypertension. Recently, the role of hypertension in the risk of vascular cognitive impairment and dementia has been highlighted, and there are studies to show that control of hypertension may slow this process. Furthermore, as many elderly individuals will also develop type 2 diabetes or impaired renal function, the risk of hypertension in these patients is more pronounced. New guidelines have tried to provide evidence-based treatment algorithms in which control of hypertension is just one aspect of general risk factor control, with the aim of decreasing the total risk.

Intracerebral hemorrhage: getting ready for effective treatments.

PURPOSE OF REVIEW: Spontaneous intracerebral hemorrhage (ICH) is the most devastating type of stroke and a leading cause of disability and mortality in the United States and the rest of the world. The purpose of this article is to review recent advances in the management of spontaneous intracerebral hemorrhage. RECENT FINDINGS: Although no interventions have consistently shown an improvement of mortality or functional outcomes after ICH, results from multicenter prospective randomized controlled trials have shown that early hemostasis to prevent hematoma growth, removal of clot by surgical or minimally invasive interventions, clearance of intraventricular hemorrhage, and adequate blood pressure control for the optimization of cerebral perfusion pressure may constitute the most important therapeutic goals to ameliorate secondary neurological damage, decrease mortality, and improve functional outcomes after ICH. CONCLUSION: Several promising methods may be ready for routine clinical use in a few years to decrease disability and mortality from ICH.

[Mortality after surgical treatment of patients with hypertensive intracerebral hematomas].

Authors summarized the experience of specialized neurosurgical clinic for treatment of patients with stroke. From 1998 till 2008 1035 patients with hypertensive intracerebral hematomas were examined and treated in the clinic. 635 patients were operated, 400 received conservative treatment. Volumes of hematomas varied from 3 to 130 ml. Mean volume of hematoma in the "surgical" group was 52.9 ml (SD = 23.1), in the "conservative" group -- 37.2 ml (SD = 22.9). Two types of indications for surgery were defined: a) indications for life-saving surgery; b) indications for surgical treatment, implying achievement of good functional result. Hematomas were removed using different techniques: craniectomy or craniotomy -- 123 patients; minimally-invasive craniotomy and limited encephalotomy -- 78; puncture aspiration -- 65; puncture aspiration combined with local fibrinolysis (prourokinase) -- 291; combined procedures (including endoscopic) -- 49; external ventricular drainage -- 29. 30-days mortality in the "surgical" group was 29%, in the "conservative" group -- 38.7%. Critical volumes of hematomas of different localization with maximal effect on mortality were distinguished. Main causes of lethal outcome in the "surgical" group were the following: pulmonary artery thomboembolism -- 21.5%, pneumonia -- 29%, recurrent hemorrhage -- 19.5%. Therefore, surgical management of hypertensive intracerebral hematomas in selected groups of patients is associated with lower rate of mortality, in comparison with conservative management. Basically, it refers to the patients in severe condition, with volumes of hematoma above critical limits specific for certain localization.
