无症状脑梗死的临床意义 总被引:27,自引:0,他引:27
无症状脑梗死 (silentbraininfarction ,SBI)是指无卒中病史 ,无明确神经系统定位体征 ,由影像学或尸检发现的梗死灶 ,包括 2种情况 :一是无卒中史人群中存在的脑梗死灶 ;二是卒中患者中存在的不能解释其症状体征的梗死灶。“无症状”并非指机体处于无病痛的良好状态。脑梗死的机制是各种原因引起的脑血管闭塞 ,导致脑组织缺血缺氧坏死 ,因此绝大多数患者都能找到缺血的征兆。所谓的“无症状”主要是指无定位体征 ,并不排除如头痛、头昏、智能减退等一般症状。同时 ,还可通过这些蛛丝马迹及早发现患者脑缺血的情况… 相似文献

BACKGROUND: Inflammatory mechanisms in heart disease are of great interest. The proinflammatory cytokine interleukin (IL) 6 has been linked to increased morbidity in unstable angina pectoris and depressed myocardial function in heart failure (HF). METHODS: We studied the relation of IL-6 levels to C-reactive protein (CRP), infarction size, left ventricular function, and HF in acute myocardial infarction (MI) and after hospital discharge in 31 consecutive patients (19 males, mean age 69+/-13 years). Blood sampling for IL-6 was performed on admittance, four times on day 1, twice on day 2, and once daily on days 3-5, and 6 and 12 weeks later. Clinical signs of HF were evaluated daily during hospitalization and after 6 and 12 weeks. Echocardiography was performed on day 3 and at 6 weeks. RESULTS: IL-6 showed a curved time course with elevated levels already on admittance (mean+/-S.D. 19.3+/-26.9 ng/l), thereafter increasing to a peak on days 1 and 2 (maximum 68.5+/-152.9 ng/l), and then declining rapidly to lower, although not normalized, levels during hospitalization and at 6 and 12 weeks. CRP showed a similar time pattern, but with a later peak and a seemingly less rapid decline in levels. Mean levels of IL-6 and CRP on days 1-5 correlated highly (r=0.794, p<0.0001). IL-6 and infarction size did not correlate. HF during hospitalization and at 6 weeks was not related to IL-6; however, patients with HF at 12 weeks had higher IL-6 levels, both at 6 and 12 weeks. Patients on ACE inhibitors or diuretics at discharge had higher IL-6 levels at 6 weeks. IL-6 during hospitalization was not related to LVF; yet, patients with depressed LVF in the hospital and at 6 weeks had higher IL-6 levels at 6 and 12 weeks. CONCLUSIONS: IL-6 in acute MI shows a curved time course and is highly correlated to CRP. It peaks on days 1 and 2 and remains elevated even after 12 weeks. Increased IL-6 levels after hospital discharge are associated with HF and depressed LVF. Whether anti-inflammatory agents will influence left ventricular dysfunction and outcome postacute MI has yet to be determined. 相似文献

Plasma fibrinogen, C-reactive protein (CRP), and interleukin-6 (IL-6) levels in patients with acute myocardial infarction (AMI) receiving thrombolysis have been related to prognosis. The aim of this study was to investigate the time course of plasma fibrinogen, CRP, and IL-6 levels during the in-hospital phase in patients with AMI receiving thrombolysis, and their relationship to in-hospital and prognosis after 12-months follow-up. In 40 patients presenting with AMI within 6 hours of symptom onset and treated with thrombolysis, plasma fibrinogen, CRP, and IL-6 levels were measured on admission and after 6, 12, 24, 48, and 72 hours; 7 days; and 6 months. Patients with other diseases that can alter fibrinogen, CRP, or IL-6 levels were excluded. Patients had a clinical follow-up at 6 and 12 months, and the following cardiac events were recorded: cardiac death, recurrent angina, recurrent AMI, and heart failure. Plasma fibrinogen concentrations decreased significantly (p <0.01 vs admission levels) at 12 hours (425 +/-94 vs 322 +/-132 mg/dL), started to increase at 24 hours, reached peak value at 72 hours (602 +/-209 mg/dL), remained elevated at 7 days, and were back to admission levels at 6 months (375 +/-79 mg/dL). CRP levels increased significantly at 12 hours (0.73 +/-0.43 vs 0.23 +/-0.11 mg/dL, p <0.01), reached peak value at 72 hours (7.66 +/-3.28 mg/dL), decreased significantly on day 7 (2.32 +/-1.17 mg/dL), and at 6 months were within normal limits (0.49 +/-0.29 mg/dL). IL-6 levels increased significantly at 6 hours (14.03 +/-8.13 vs 6.37 +/-3.88 pg/mL, p <0.05), reached peak value at 24 hours (59.49 +/-23.57 pg/mL), started to decrease at 48 hours, and at 6 months were within normal limits (2.25 +/-1.24 pg/mL). During the in-hospital phase 33 patients had an uneventful course and 7 patients had complications (3 post-AMI angina; 4 heart failure). During the 12-month follow-up period 28 patients had an uneventful course, and 12 patients had complications (1 cardiac death, 5 recurrent angina, 2 recurrent AMI, and 4 heart failure). Regarding the in-hospital prognosis, fibrinogen, CRP, and IL-6 levels were significantly higher (p <0.05) in patients with complications from 48 to 72 hours, from 12 hours until day 7, and from 6 hours until day 7, respectively. During the 12-month follow-up period fibrinogen, CRP, and IL-6 levels were significantly higher in patients with complications (at 48, 24, and 24 hours, respectively) only in the subgroup of patients who had complications within the first 6 months following AMI. Multivariate analysis showed that CRP at 48 hours was the most important factor related to in-hospital prognosis (p = 0.02), and ejection fraction followed by CRP at 24 hours (p = 0.02) to 6-month prognosis (p = 0.018). Fibrinogen, CRP, and IL-6 levels alter in patients with AMI receiving thrombolysis, and are related both to in-hospital and to 6-month follow-up prognosis. 相似文献

Association between PRKCH gene polymorphisms and subcortical silent brain infarction 总被引:1,自引:0,他引:1
Serizawa M Nabika T Ochiai Y Takahashi K Yamaguchi S Makaya M Kobayashi S Kato N 《Atherosclerosis》2008,199(2):340-345
Recently, a large-scale genetic epidemiological study has shown significant association of single nucleotide polymorphisms (SNPs) in the protein kinase C η (PRKCH) gene with cerebral infarction, particularly, with lacunar infarction. To extend the findings, we tested association of two SNPs previously reported – rs3783799 and rs2230500 – in PRKCH with silent lacunar infarction (SLI), which has drawn substantial attention in the aging societies. Disease association was tested in the case–control study design. Subjects with and without SLI were recruited from people who underwent a health-screening examination including brain MRI. Two SNPs were genotyped and proven to be in complete linkage disequilibrium (D′ = 1.00, r2 = 1.00) and thus showed comparable results of disease association, which were reproduced in two panels collected independently. In the entire population involving 295 cases and 497 controls, two SNPs remained to be significantly associated with SLI under a dominant model even after adjustment for confounding factors such as hypertension (e.g., genetic effects of rs2230500, P = 0.0026 for AA + AG vs. GG, adjusted odds ratio = 1.27; 95% CI, 1.09–1.48). As the two SNPs appear to be common only in Asian people, further replication study is warranted in the other Asian populations as well as the Japanese. 相似文献

Frequency and pathogenesis of silent subcortical brain infarction in acute first-ever ischemic stroke 总被引:1,自引:0,他引:1
OBJECTIVES: We have often observed silent subcortical brain lesions on CT or MRI in first-ever ischemic stroke, but there is little published information on the relationship of these lesions to stroke subtypes. Here, we describe the incidence of MRI-detected silent subcortical brain lesions, including infarctions and white matter lesions, in a series of patients with first-ever ischemic stroke classified according to stroke subtypes. We also discuss the pathogenesis of these silent subcortical lesions. PATIENTS: We evaluated 171 patients with acute first-ever ischemic stroke. METHODS: The subjects were divided into three groups: lacunar, atherothrombotic and cardioembolic infarction groups. We evaluated silent subcortical brain infarction (SSBI), enlargement of perivascular space (EPS), and other white-matter lesions using MRI. RESULTS: Hypertension was observed in 67.6% of lacunar infarction, 57.1% of atherosclerotic infarction, and 54.1% of cardioembolic infarction. SSBI was more frequently observed in lacunar infarction than the others (lacunar vs. atherothrombotic vs. cardiogenic infarction, 81.5% vs. 44.4% vs. 42.1%, p=0.006). High-grade EPS (grade 2 or higher) was also observed more frequently in lacunar infarction than in the others (lacunar vs. atherothrombotic vs. cardiogenic infarction, 63.3% vs. 24.2% vs. 0%, p<0.001). Scheltens' score of silent subcortical lesions was significantly higher in lacunar infarction than in the others. CONCLUSIONS: The frequency of silent subcortical ischemic brain lesions was significantly higher in lacunar infarction than in atherosclerotic or cardioembolic infarction. We suggest that the pathogenesis of silent subcortical ischemic brain lesions is common to that of lacunar infarction, that is, small-vessel vasculopathy. 相似文献

AIM: The significance of preoperative serum IL-6, TNFα and CRP levels in the progression of colorectal cancer (CRC) has not been fully elucidated. Our intention was to investigate their role and identify their prognostic significance.METHODS: The IL-6, TNFα and CRP levels were measured in 74 CRC patients and the relationships between their elevations and both the clinicopathological factors and prognosis of patients were investigated. Serum concentrations of human IL-6 and TNFα were determined by enzyme-linked immunosorbent assay (ELISA). CRP was measured by an immunoturbinometric method. RESULTS: Median IL-6, TNFα and CRP levels were significantly higher in CRC patients than in normal controls. High levels of serum IL-6, TNFα and CRP were correlated with larger tumor size. Furthermore, high IL-6 and high CRP levels were associated with reduced overall survival. CONCLUSION: Serum IL-6, TNFα and CRP levels definitely increase in CRC patients. Pre-operative serum elevation of IL-6 and CRP was thus found to be predictor of the prognosis of CRC patients. The clinical value of TNFα in CRC needs to be further investigated. 相似文献
