The effect of 24 h blood pressure levels on early neurological recovery after stroke 总被引:1,自引:0,他引:1
OBJECTIVES: To assess the influence of 24 h blood pressure (BP) levels on functional recovery 1 week after stroke and the effect of antihypertensive therapy on 24 h BP levels. DESIGN: Prospective study of patients admitted to hospital over 1 year with first in a lifetime stroke who underwent 24 h BP and casual measurements. Setting. Medical wards in a teaching hospital. Subjects. Of 160 patients, 72 patients admitted to hospital within 24 h of stroke onset were investigated. Patients with conditions and therapy that interfered with autonomic and sympathetic function were excluded. Interventions. All subjects underwent 24 h BP and casual recordings on admission to hospital and at day seven after stroke. The mean 24 h, day and night systolic BP (SBP) and diastolic BP (DBP) and their differences (nocturnal BP dip) were recorded. Patients were divided into three groups according to whether they were taking antihypertensive therapy during the first week: (i) no therapy, (ii) therapy continued after stroke, and (iii) new therapy introduced. Main outcome measures. Functional recovery (Rankin Scale 0-1) and neurological improvement [Scandinavian Stroke Scale (SSS) >/=3 points] by 1 week of stroke. Change in circadian 24 h BP over 1 week. RESULTS: For each 10 mmHg difference between day and night time DBP, the odds for making a complete recovery were 4.63 (95% CI: 1.57-13.7, P=0.01). For each 10 mmHg difference between day and night SBP, the odds for making an improvement in neurological status was 2.24 (95% CI: 1.16-4.32; P=0.016). Significant falls in 24 h DBP (P=0.01), daytime SBP (P=0.005) and mean arterial BP (MABP) (P=0.04) over 1 week were demonstrated in patients who had just commenced antihypertensive therapy (P=0.001). CONCLUSION: An increase in day to night time BP change is favourable in short-term outcome after acute stroke. Significant falls in BP are more likely in patients started on antihypertensive therapy for the first time. Further research is required to understand the effects of circadian BP rhythm on stroke outcome. 相似文献

High blood pressure (BP) is common in acute stroke and might be associated with a poor outcome, although observational studies have given varying results. In a systematic review, articles were sought that reported both admission BP and outcome (death, death or dependency, death or deterioration, stroke recurrence, and hematoma expansion) in acute stroke. Data were analyzed by the Cochrane Review Manager software and are given as odds ratios (ORs) or weighted mean differences (WMDs) with 95% confidence intervals (CIs). Altogether, 32 studies were identified involving 10 892 patients. When all data were included, death was significantly associated with an elevated mean arterial BP ([MABP] OR, 1.61; 95% CI, 1.12 to 2.31) and a high diastolic BP ([DBP] OR, 1.71; 95% CI, 1.33 to 2.48). Combined death or dependency was associated with high systolic BP ([SBP] OR, 2.69; 95% CI, 1.13 to 6.40) and DBP (OR, 4.68; 95% CI, 1.87 to 11.70) in primary intracerebral hemorrhage (PICH). Similarly, high SBP (+11.73 mm Hg; 95% CI, 1.30 to 22.16), MABP (+9.00 mm Hg; 95% CI, 0.92 to 17.08), and DBP (+6.00 mm Hg; 95% CI, 0.19 to 11.81) were associated with death or dependency in ischemic stroke. Combined death or deterioration was associated with a high SBP (OR, 5.57; 95% CI, 1.42 to 21.86) in patients with PICH. In summary, high BP in acute ischemic stroke or PICH is associated with subsequent death, death or dependency, and death or deterioration. Moderate lowering of BP might improve outcome. Acute BP lowering needs to be tested in 1 or more large, randomized trials. 相似文献

Investigations to date have demonstrated that the underlying etiology, causes and burden of stroke may be different for women and men. However, data regarding sex differences among young cerebral ischemic stroke patients remains scarce. We conducted this study in 669 young Chinese adults with acute ischemic stroke as determined by the modified Rankin Scale at discharge. Stepwise multiple logistic regression analysis confirmed that NIHSS score (OR 1.277; 95% CI 1.179-1.383, p=0.000), diabetes mellitus (OR 0.121; 95% CI 0.0209-0.718, p=0.020) and serum glucose levels on admission (OR 1.135; 95% CI 0.997-1.293, p=0.046) independently predict short-term outcomes at discharge in young female patients with acute stroke, but the significant variables related to male patients appeared to be Apo A1 (OR 0.165; 95% CI 0.035-0.776, p=0.023) and NIHSS score on admission (OR 1.458; 95% CI 1.325-1.605, p=0.000). In our series, our data suggest that there are several sex differences for risk of cerebral infarction in young patients, which have important implications for the diagnosis, management and prognosis of stroke in young adults. 相似文献

Low cholesterol levels are associated with short-term mortality in older patients with ischemic stroke 总被引:1,自引:0,他引:1
Zuliani G Cherubini A Atti AR Blè A Vavalle C Di Todaro F Benedetti C Volpato S Marinescu MG Senin U Fellin R 《The journals of gerontology. Series A, Biological sciences and medical sciences》2004,59(3):293-297
BACKGROUND: The possible relationship between serum total cholesterol (TC) levels and outcome following ischemic stroke is still controversial. We evaluated the association between TC levels and 30-day mortality in a sample of older patients with acute ischemic stroke. METHODS: We enrolled 490 older patients with severe ischemic stroke consecutively admitted to University Hospital's Internal Medicine or Geriatrics Department. Stroke type was classified according to the Oxfordshire Community Stroke Project. The data recorded included clinical features, medical history, electrocardiogram, and blood analyses. Patients were divided into three groups by TC levels: group I (TC<4.1 mmol/L), group II (TC 4.1-5.2 mmol/L), and group III (TC>5.2 mmol/L). RESULTS: The overall mortality was 27.7%. Mortality was higher in patients with low TC levels (47.4%) compared with those with normal and high TC levels (23.0% and 24.1%, respectively). The odds ratio (OR) for short-term death was 2.17 (95% confidence interval [CI] 1.22-3.85) in group I compared with group III, after adjustment for age and gender. This result did not change after adjustment for possible confounders (OR 2.87; 95% CI 1.23-6.68). A similar trend was observed after adjustment for the Oxfordshire classification, age, and gender (OR 1.67; 95% CI 0.83-3.33). CONCLUSIONS: Short-term mortality following ischemic stroke is higher in older participants with low TC levels, independent of a large number of factors. Low TC levels might be useful in identifying frail older participants at high risk of stroke short-term mortality. 相似文献

目的:探讨急性缺血性卒中患者血清胆红素水平与病情严重程度和短期转归的关系。方法纳入连续的120例急性缺血性卒中住院患者,105例同期健康体检者作为对照组。在入院24 h内检测血清总胆红素、直接胆红素、间接胆红素以及血脂、血糖等生化指标,入院当天采用美国国立卫生研究院卒中量表(National Institutes of Health Stroke Scale, NIHSS )评定神经功能缺损情况,NIHSS评分<8分定义为轻度卒中,≥8分定义为中重度卒中。在出院时或发病后14 d采用改良 Rankin 量表(modified Rankin Scale, mRS)评估临床转归,0~2分定义为转归良好,>2分定义为转归不良,并再次检测血清总胆红素、直接胆红素和间接胆红素水平。结果中重度卒中组血清总胆红素、直接胆红素和间接胆红素水平均显著高于轻度卒中组(P <0.01)和对照组(P <0.01)。多变量 logistic 回归分析显示,血清总胆红素[优势比(odds ratio, OR)1.855,95%可信区间(confidence interval, CI)1.390~2.475;P <0.01]、间接胆红素(OR 3.380,95% CI 1.271~11.901;P <0.05)和直接胆红素(OR 3.51,95% CI 1.062~11.473;P <0.01)水平升高均与基线病情严重程度存在显著独立相关性。单变量分析显示,入院时血清总胆红素水平升高与短期转归不良有关(P <0.05),但校正其他混杂因素后丧失统计学意义(OR 2.411,95% CI 0.803~7.243;P >0.05)。结论脑梗死急性期患者血清胆红素水平呈应激性升高,并且与神经功能缺损程度存在显著相关性,但与短期转归无关,可能是机体对卒中事件的一种防御反应。 相似文献

High initial blood pressure after acute stroke is associated with poor functional outcome 总被引:8,自引:0,他引:8
OBJECTIVE: To evaluate the relationship between high initial blood pressure and functional outcome in patients with acute stroke. DESIGN: An observational study based on the data from the Intravenous Nimodipine West European Stroke Trial (INWEST). INWEST was a placebo-controlled randomized study terminated prematurely; subsequent analysis found a correlation between diastolic BP (DBP) reduction caused by high-dose nimodipine and unfavourable outcome. Subjects. Of the 295 patients with acute ischaemic stroke (within 24 h) recruited in the INWEST, 265 were included in this analysis [n = 92 for placebo, n = 93 for low-dose nimodipine (1-mg h(-1)) and n=80 for high-dose nimodipine (2-mg h(-1))]. Definition. Initial BP was defined as BP at the time of randomization. Normal initial BP (NIBP)=systolic BP (SBP) 120-160 and DBP 60-90 mmHg (n=126). Four alternatives were defined as high initial BP (HIBP): (1) >160/90 (n=126), (2) >170/95 (n=106), (3) >180/100 (n=63), (4) >190/105 (n=45). Main outcome measures. Combined death or dependency (DD) (Barthel index < 60) at 21 days. RESULTS: In multiple logistic regression analyses, the odds ratio [OR] for DD at day 21 was significantly higher in patients with any definition of HIBP than with NIBP. For all patients, OR and 95% confidence intervals [CI] for 160/90 versus NIBP=3.1, 1.3-7.3, respectively; for 170/95=3.3, 1.4-8.1; for 180/100=7.0, 2.1-22.8; for 190/105=3.7, 1.1-12.4. For only placebo patients, OR and 95% CI for 160/90=4.8, 1.2-19.3; for 170/95=4.4, 1.1-17.8; for 180/100=12.7, 2.2-74.7; for 190/105=5.6, 1.1-30.0. The outcome was similar at 24 weeks but did not reach statistical significance for the placebo patients. CONCLUSION: Patients with HIBP had a poor functional outcome after acute stroke. 相似文献

Blood pressure (BP) monitored within 24 h from the beginning of intravenous thrombolysis (IVT) with alteplase, is one of the important factors affecting the prognosis of patients with acute ischemic stroke (AIS). This study aimed to explore longitudinal BP trajectory patterns and determine their association with stroke prognosis after thrombolysis. From November 2018 to September 2019, a total of 391 patients were enrolled consecutively during the study period, and 353 patients were ultimately analyzed. Five systolic (SBP) and four diastolic blood pressure (DBP) trajectory subgroups were identified. The regression analysis showed that when compared with the rapidly moderate stable group, the continuous fluctuation‐very high level SBP group (odds ratio [OR]: 2.743, 95% confidence interval [CI]: 1.008–7.467) was associated with early neurological deterioration (END). Both the rapid drop‐high level SBP (OR: 0.448, 95% CI: 0.219–0.919) and DBP groups (OR: 0.399, 95% CI: 0.219–0.727) were associated with early neurological improvement (ENI). Moreover, there was a U‐shaped correlation between the OR value of SBP trajectory group and favorable outcome (the modified Rankin Scale [mRS] score 0–2) at 3 months: the slow drop‐low level SBP group represent a well‐established unfavorable outcome risk factor (OR:5.239, 95% CI: 1.271–21.595), and extremely high SBP—the continuous fluctuation‐very high level SBP group, are equally associated with elevated unfavorable outcome risk (OR:3.797, 95% CI: 1.486–9.697). The continuous fluctuation‐very high level DBP group was statistically significant in mRS (OR: 3.387, CI: 1.185–9.683). The BP trajectory groups show varying clinical features and risk of neurological dysfunction. The findings may help identify potential candidates for clinical BP monitoring, control, and specialized care. 相似文献

Manipulation of blood pressure (BP) in acute stroke may improve outcome. Despite various studies, data on the prognostic significance of early BP in stroke remain unclear. Therefore, we studied the relationship between various BP variables in the acute phase of stroke and functional outcome at 3 months. Blood pressures were collected by reviewing BP records of 817 patients who were admitted to our stroke unit between 1987 and 1992. Besides the first systolic and diastolic admission BP (SBP and DBP), we also used the mean of the daytime as well as the night-time systolic and diastolic BP values. Finally, we studied the relationship between the decrease in BP between day 0 and 4 and outcome. As dependent outcome variable we used the Rankin handicap score at 3 months dichotomized in a score >3 (poor outcome) vs a score 3 (good outcome). A total of 430 patients were admitted within 24 h following stroke onset. There was no significant relationship between the systolic and diastolic BP and the outcome at 3 months. Only night-time systolic BP 165 mm Hg (odds ratio (OR) 2.8; 95% CI 1.1-6.8), night-time diastolic BP 60 mm Hg (OR 8.1; 95% CI 1.1-58.3), and a decrease in daytime diastolic BP between day 0 and 4 of 10 mm Hg (OR 3.0; 95% CI 1.1-7.9) showed a significant relationship with poor outcome. Our findings suggest that admission BP values may not reliably reflect any impact of BP on stroke outcome. They also suggest a potential differential effect of BP manipulation: increasing or decreasing BP may be beneficial for patients with BP extremes in one direction, but detrimental for those with BP values in the opposite direction. 相似文献
