缺血性脑卒中具有高病发率、高致残率、高病死率、高复发率及高医疗费用的特点,但到目前为止,对其真正有效的治疗手段仍很有限,因此寻找缺血性脑卒中的危险因素并及早进行预测、预防就显得格外重要。除了已知的众多危险因素如高血压、糖尿病、血脂异常、冠心病、吸烟、脑卒中家族史及老龄等之外,还有一些危险因素尚待发现。随着研究的不断深入,脑血管反应性降低在缺血性脑卒中发病、发展中的作用逐渐被证实,但尚未引起大家的足够重视,国内的相关研究更为少见。 相似文献

目的 调查社区卒中患者卒中后抑郁(PSD)的患病率及其相关影响因素. 方法在北京市城区选择五家二级医院所属社区卫生服务中心,登记2003年1月至2006年12就诊的缺血性脑卒中患者.采用抑郁自评量表(SDS)评价脑卒中患者PSD患病情况,同时还收集了脑卒中起病情况、脑卒中危险因素等资料. 结果共登记1089例脑卒中患者,其中1074例符合入选标准并有完整资料,平均年龄(65.0±8.9)岁,脑卒中病程中位数为13.0个月.PSD总患病率为49.9%(536/1074),其中轻、中、重度PSD分别占52.2%、36.0%和11.8%.不同脑卒中病程的PSD患病率差别不大,脑卒中后6个月内、7~18个月、18个月以上的PSD患病率分别是51.3%、47.1%和53.2%.PSD患病与文化程度、日常生活依赖、认知功能情况、脑卒中发作次数、文化程度独立相关. 结论在社区卫生服务机构就诊的缺血性脑卒中患者中有较高的PSD患病率,但是以轻中度为主,积极采取有效的早期干预,可以有效控制PSD的发生和发展,促进患者神经功能的康复,改善预后,提高生活质量.Abstract: Objective To estimate the prevalence and related risk factors of post-stroke depression (PSD) in ischemic stroke survivors from community-based medical centers in urban areas of Beijing.Methods Five community-based medical centers in urban areas of Beijing were selected.Patients with first-ever or recurrent ischemic stroke were evaluated from January 2003 to December 2006. The prevalence of PSD was evaluated by Self-Rating Depression Scale (SDS), and the information on the onset of stroke, vascular risk factors and living style was also collected.Results Totally 1089 stroke patients were registered, 1074 cases among which had complete information and met inclusion criteria. The mean age of the patients was (65.0 ± 8.9) years with a median stroke course of 13.0 months. The overall prevalence of PSD was 49.9% (536/1074), and the proportions of mild, moderate and major PSD were 52.2%, 36.0% and 11.8%, respectively. There were no significant differences in prevalence of PSD among different stages of stroke and the prevalence of PSD was 51.3% within 6 months after stroke onset, 47. 1% during 6-18 months and 53.2% after 18months. Low education, activities of Daily Living (ADL) dependence, cognition impairment and recurrence of stroke were independent risk factors for PSD.Conclusions The prevalence of PSD among ischemic stroke patients is higher in community-based medical centers, but most of PSD patients are mild or moderate. More effective early intervention should be adopted to decrease PSD,promote the recovery of neural function and improve their quality of life. 相似文献

Background and Objective To investigate the effects of simvastatin on lipid lowering therapy and platelet activation in elderly patients with hypercholesterolemia. Methods Fasting serum lipids, CD63, CD41a, serum glucose, hepatic and renal function, routine urine analysis (UA) were measured in 50 healthy subjects, and in 50 elderly patients with hypercholesterolemia before and after 4 weeks treatment with simvastatin (20mg daily for 4 weeks). Results 1. After simvastatin treatment for 4 weeks, the fasting serum level of lipids in elderly patients with hypercholesterolemia was significantly lower than before treatment (P<0.01). 2. CD63 and CD41a were decreased after treatment compared with before, respectively (1.36 0.34) vs (4.26 1.06), (P<0.01) and (123.54 19.73) vs (253.78 16.75), (P<0.01). 3. Changes in serum lipid level tended to be positively correlated with the declines in CD63 and CD41a, but there was no statistical significance (P>0.05). Conclusions The results suggested that lipid lowering therapy with simvastatin inhibit platelet activity.(J Geriatr Cardiol 2007;4:215-217.) 相似文献

Rapid effects of simvastatin on lipid profile and C-reactive protein in patients with hypercholesterolemia 总被引:3,自引:0,他引:3
BACKGROUND: Rapid lowering of low-density lipoprotein (LDL) cholesterol levels as well as C-reactive protein (CRP) by administration of drugs may produce early benefit to the coronary endothelium in patients with coronary heart disease and reduce angina and coronary events after revascularization. Limited information has been available in evaluating a potentially effective first 2-week therapeutic approach for the treatment of patients with hypercholesterolemia using a statin. HYPOTHESIS: The study was undertaken to investigate whether a rapid LDL cholesterol and CRP reduction can be achieved by 2-week simvastatin therapy using a common lipid-lowering protocol in patients with hypercholesterolemia. METHODS: Forty-two patients were randomly assigned to 20 or 40 mg/day of simvastatin. Blood samples were drawn at Day 0 and at Day 14 for measuring lipid profile, CRP levels, and hepatic enzymes in all patients. RESULTS: The results showed that both doses of simvastatin (20 and 40 mg) induced significant reductions in total cholesterol (TC, 25 and 38%) and LDL cholesterol (31 and 46%) compared with baseline. However, the highest dose of simvastatin (40 mg) resulted in significantly greater reductions in TC and LDL cholesterol (p = 0.04, p = 0.02, respectively) compared with the group receiving 20 mg (p < 0.04, p < 0.02, respectively). A less significant reduction was observed in mean triglycerides (TG) level (16 and 25%) compared with TC and LDL cholesterol. There was no significant difference in mean high-density lipoprotein (HDL) cholesterol levels compared with baseline in either group. In addition, both doses of simvastatin induced significant reductions in mean CRP levels on Day 14 (22.3 and 23.1%) in a non dose-dependent manner (p < 0.001, respectively. CONCLUSIONS: Our data suggest that a common daily dose of simvastatin, especially 40 mg, is an effective 2-week therapy for patients with hypercholesterolemia, and benefit to the vascular endothelium can be derived quickly by reduction of CRP levels. 相似文献

Summary We report the results of a two center study on the use of the HMG Co A reductase inhibitor, simvastatin, in 44 patients suffering from familial hypercholesterolemia or from primary hypercholesterolemia of unknown etiology. The study included two separate phases: Phase I was part of a multicenter, 4-week, placebo-controlled trial; phase II was a 6-month, open extension trial, the object of which was to reduce low density lipoprotein (LDL) cholesterol levels to below the 50th percentile by increasing the dose of simvastatin, by the use of additional lipid-lowering medication, or both. Our phase I results were commensurate with those reported for the entire international cohort of 272 patients, indicating a clear dose-response relationship, with approximately 75% of the maximum reduction in LDL-C levels being achieved with 20 mg/day and over 90% of the maximum being achieved with 40 mg of simvastatin per day. In the open extension trial, the results from the 2 centers were essentially similar. Total cholesterol fell by 29% on the 20 mg/day dose and by 34% on the full dose of 40 mg/day. LDL-C levels were reduced by 40% on the 40 mg/day schedule, and triglycerides also fell to between 20% and 40% below baseline values. HDL-C concentration rose by 14% and 17.6%. The effects of simvastatin were uniform, both within and between the two cohorts. The addition of cholestyramine caused a further substantial reduction in LDL-cholesterol to below 55% of the initial value in four patients, whereas bezafibrate further enhanced the fall in triglycerides and the increase in high-density lipoprotein cholesterol, but had only a slight effect on LDL-C levels. Adverse reactions included asymptomatic increases in plasma creatine kinase activity, generally associated with previous physical exertion, and transient rises in transaminase levels. In one patient with a history of alcoholic excess, transaminase levels were persistently greater than normal. These results indicate that the HMG Co A reductase inhibitor, simvastatin, is a powerful therapeutic agent for the lowering of plasma cholesterol levels in patients with genetic hypercholesterolemia. 相似文献

Summary Changes in plasma concentrations of high density lipoproteins (HDL) and triglycerides may partly explain the ability of cholesterol-lowering drugs to decrease the incidence of coronary heart disease. We measured the response of fasting plasma lipids, lipoproteins, and apolipoproteins in 46 subjects with Type IIa hypercholesterolemia treated with simvastatin for 3 months. The initial dose of simvastatin (10 mg/day) was subsequently increased up to 40 mg/day if the plasma cholesterol concentration had not fallen below 5.2 mmol/l. Plasma concentrations of HDL cholesterol and of the apolipoproteins AI and AII were increased by simvastatin. The increase in HDL cholesterol (9%) was due to increases in both subfractions (HDL2 17%; HDL3 7%), changes that would be consistent with a beneficial effect on cardiovascular risk. Simvastatin decreased plasma triglyceride concentrations by 25%. Plasma total cholesterol concentrations fell by 35% after 3 months of treatment; this fall was proportional to the initial concentration and was due almost entirely to a 45% fall in low density lipoprotein cholesterol. In contrast, plasma concentrations of lipoprotein Lp(a) were not affected by simvastatin. 相似文献
