代谢综合征在缺血性卒中患者心脑血管事件发生中的作用

Objective To explore the association between metabolic syndrome (MS) and risk of cardiovascular disease events (CVD) in patients with ischemic stroke. Method A total of 1087 patients with ischemic stroke were enrolled from 5 community-based medical centres and underwent baseline evaluation on risk factors of stroke during the period of Jar. 2003 to Dec. 2006. After baseline survey, all patients were followed up until Dec 31, 2008 and new CVD events were recorded. MS was defined using CDS criteria. Proportional hazard models were used to assess the HRus and 95% CI of CVD events associated with MS and other components. Results The prevalence of MS was 40. 4% at baseline. During an average follow-up of 3.5 years, 178 patients developed new CVD events. After adjusted for age, gender, smoking,drinking, marriage status, education level, hospitalization, recurrence of stroke, stroke duration,depression, cognition impairment and ADL, MS remains the independent predictor for the risk of CVD events. Compared with patients with non-MS, the risk of CVD events increased by 44% (HR:1.44, 95%CI:1.06-1.95 ). The risk of CVD also increased with the number of MS components. Compared with patients with 1 or less than 1 components of MS, the risk of CVD events increased by 30% (HR:1. 30,95%CI:0.83-2.04) in those with 2 components and by 69% ( HR: 1.69,95% CI: 1.11-2.56) in those with 3or more components of MS. Hypertension and hyperglycemia and impaired fasting glucose also served as independent risk factors for CVD event ( all P ＜ 0. 001 ) . Conclusions MS was independently associated with increased risk of CVD events in patients with ischemic stroke. There was a dose-response relationship between the numbers of MS components and the risk of CVD event.     

代谢综合征在缺血性卒中患者心脑血管事件发生中的作用

目的 探讨缺血性卒中患者合并代谢综合征(metabolic syndrome,MS)与心血管(cardiovascular disease,CVD)事件发病的关系.方法于2003年1月至2006年12月期间对北京市5家二级医院所属的社区卫生服务中心/站就诊的首次或二次缺血性卒中患者进行登记,进行基线调查,随后进行随访,记录CVD事件发病情况,随访截止到2008年12月31日.采用2004年中华医学会糖尿病学分会关于代谢综合征的建议定义MS,用COX比例风险模型计算风险比(HR)和95%可信区间(95%CI),并控制各种混杂因素.结果共入选1087例缺血性卒中患者,基线调查时MS患病率为40.4%.随访时间平均3.5年,共有178例患者新发CVD事件.结果显示,MS是CVD事件发生的独立预报因素,在控制了年龄、性别、吸烟、饮酒、婚姻、文化程度、就诊医院、卒中次数、卒中病程、抑郁状态、认知功能、ADL依赖等因素后,MS组CVD事件发病危险是非MS组的1.44倍(HR:1.44,95% CI:1.06～1.95);结果还显示,与仅有1个MS组分的患者相比,存在2个、3个以上MS组分的患者,其CVD事件发病的危险分别增加了30%(HR:1.30,95%CI:0.83～2.04)和69%(HR:1.69,95% CI:1.11～2.56).MS各组分中,高血糖和高血压是CVD事件发病的独立危险因素,危险分别增加了78%(HR:1.78,95%CI:1.26～2.52)和91%(HR:1.91,95%CI:1.11～3.30).结论 MS是缺血性卒中患者发生CVD事件的独立危险因素,CVD事件的发生与代谢组分异常的数量呈剂量反应关系.

Ankle-brachial index as a predictor of all-cause and cardiovascular disease mortality in 3733 Chinese patients with high cardiovascular risk

Objective To assess the association between 1-year risk of all-cause and cardiovascular disease （CVD） mortality and ankle-brachial index （ABI） in Chinese patients who were at high CVD risk. Methods Totally 3733 patients with high CV risk had bilateral ABI measurements at baseline and were followed up for 1-1.5 years. Patients were divided to four groups： 1） coronary heart disease （CHD）; 2） ischemic stroke （IS）; 3） diabetes mellitus （DM）; 4） very high risk group（VHR）, low ABI was defined as 〈0.9. Results A total of 3179 patients were analyzed. The prevalence of low ABI was 28.1%. At 1 year, all-cause mortality was 8.7%, and 27.6% was attributable to CVD; mortality due to CV events was 4.8% and 1.5%. After adjusting other risk factors the hazard ratio of low ABI was 1.623 for all-cause mortality and 2.304 for CVD mortality. Similar in patient with and without low ABI, respectively were found in four groups.Conclusion ABI is a strong and independent predictor ofrnortality. Patients with a low ABI have a substantially increased risk of all-cause mortality and CVD mortality （J Geriatr Cardio12010; 7：17-20）.     

Nonalcoholic fatty liver disease is a novel predictor of cardiovascular disease

AIM:To clarify whether nonalcoholic fatty liver disease(NAFLD)increases the risk of cardiovascular disease.METHODS:We carried out a prospective observational study with a total of 1637 apparently healthy Japanese men and women who were recruited from a health check-up program.NAFLD was diagnosed by abdominal ultrasonography.The metabolic syndrome(MS)was defined according to the modified National Cholesterol Education Program(NCEP)ATP Ⅲ criteria.Five years after the baseline evaluations,the incidence of cardiovascular disease was assessed by a self-administered questionnaire.RESULTS:Among 1221 participants available for outcome analyses,the incidence of cardiovascular disease was higher in 231 subjects with NAFLD at baseline(5 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage)than 990 subjects without NAFLD(3 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage).Multivariate analyses indicated that NAFLD was a predictor of cardiovascular disease independent of conventional risk factors(odds ratio 4.12,95% CI,1.58 to 10.75,P = 0.004).MS was alsoindependently associated with cardiovascular events.But simultaneous inclusion of NAFLD and MS in a multivariate model revealed that NAFLD but not MS retained a statistically significant correlation with cardiovascular disease.CONCLUSION:Although both of them were predictors of cardiovascular disease,NAFLD but not MS retained a statistically significant correlation with cardiovascular disease in a multivariate model.NAFLD is a strong predictor of cardiovascular disease and may play a central role in the cardiovascular risk of MS.     

Inflammatory markers and elderly patients with stroke

C-reactive protein (CRP) is associated with unfavorable outcome in patients with acute ischemicsyndromes and in patients with chronic stable angina.Elevated CRP levels suggestive of heightened inflammatorystate in vascular conditions are often associated with elevated interleukin-6 (IL-6) levels.The aim of our study wasto show the predictive importance of CRP and IL-6 levels in patients with ischemic stroke that has not been fullyelucidated.Design We studied 647 consecutive elderly patients (>65 years) with stroke who were documentedwith ischemic stroke,presence of significant carotid atherosderosis and absence of atrial fibrillation.The studypopulation included 150 patients (74 men,76 women,mean age 74±2).Patients underwent evaluation of highsensitive CRP and IL-6 levels at baseline,during hospitalization and at discharge.Results In-hospital mortalitywas 6%,1 year mertality was 15% and a second cerebrovascular event occurred in 12% of patients.Those with in-hospital events had significantly higher baseline CRP and IL-6 levels than patients without events (3.8+1.1 vs1.9±0.9 mg/L,P<0.01 and 13.8±3.4 vs 6.3±2.1 pg/ml,P<0.01,respectively).Also CRP and IL-6levels were significantly higher in those patients with an event within 3 months of discharge compared to patientswithout an event (3.6±1.3 vs 1.1±0.7 mg/L,P<0.01 and 14.2±3.7 vs 5.4±1.6 pg/ml,P<001,respectively).Both base line CRP levels and IL-6 were predictive of events both in-hospital and after 3 months whileCRP and IL-6 levels at baseline were not associated with a poor 1 year prognosis.Elevated CRP levels wereassociated with an unfavorable outcome only when IL-6 levels were also elevated.In a stepwise multivariate analysisIL-6 level was a stronger predictor of outcome than CRP.Conclusions In conclusion,elevated CRP and IL-6levels may identify elderly patients at increased medium term risk,but do not predict one year events in this subsetof patients.CRP levels predict events only when they are coupled with IL-6 levels.(J Ceriatr Cardiol 2004;1:44-48.)     

Biomarkers and potential pathogenesis of colorectal cancer-related ischemic stroke

AIM To investigate the specific biomarkers and potential pathogenesis of colorectal cancer-related ischemic stroke(CRCIS).METHODS A retrospective study was conducted on CRCIS patients(colorectal cancer patients with ischemic stroke without conventional stroke risk factors) registered at seven centers between January 2007 and December 2017. Clinical data and laboratory and imaging findings were compared with age-and sex-matched patients with colorectal cancer(CRC) without ischemic stroke that were admitted to the same hospital during the same period. Univariate and multivariate analyses were performed to analyze the independent risk factors for CRCIS. A receiver operator characteristic curve was configured to calculate the optimal cut-off value of the products of the independent risk factors for CRCIS. RESULTS A total of 114 CRCIS patients and 114 CRC patients were included. Multiple lesions in multiple vascular territories were common in CRCIS patients(71, 62.28%). The levels of plasma D-dimer, carcinoembryonic antigen(CEA), cancer antigen 125, and neutrophil count were significantly higher in CRCIS patients than in CRC patients. Multiple logistic regression analysis revealed that plasma D-dimer levels [odds ratio(OR) = 1.002, 95% confidence interval(CI): 1.001-1.003, P 0.001], CEA levels(OR = 1.011, 95%CI: 1.006-1.015, P 0.001), and neutrophil count levels(OR = 1.626, 95%CI: 1.268-2.087, P 0.001) were independent risk factors for CRCIS. In addition, receiver operator characteristic curve revealed that the area under curve for the products of plasma D-dimer, CEA, and neutrophil count was 0.889 ± 0.022(95%CI: 0.847-0.932, P 0.001), and the optimal cut-off value for the product was 252.06, which was called the CRCIS Index, with a sensitivity of 86.0% and specificity of 79.8%.CONCLUSION Hypercoagulability induced by elevated CEA and neutrophils may be an important cause of CRCIS. The CRCIS index, which serves as a biomarker of CRCIS, needs further study.     

Chronic pancreatitis and the heart disease: Still terra incognita?

BACKGROUND It has been suggested that chronic pancreatitis(CP) may be an independent risk factor for development of cardiovascular disease(CVD). At the same time, it seems that congestive heart failure(CHF) and CP share the responsibility for the development of important clinical conditions such as sarcopenia, cachexia and malnutrition due to development of cardiac cachexia and pancreatic exocrine insufficiency(PEI), respectively.AIM To explore the evidence regarding the association of CP and heart disease, more specifically CVD and CHF.METHODS A systematic search of MEDLINE, Web of Science and Google Scholar was performed by two independent investigators to identify eligible studies where the connection between CP and CVD was investigated. The search was limited to articles in the English language. The last search was run on the 1 st of May 2019.The primary outcomes were:(1) Incidence of cardiovascular event [acute coronary syndrome(ACS), chronic coronary disease, peripheral arterial lesions]in patients with established CP; and(2) Incidence of PEI in patients with CHF.RESULTS Out of 1166 studies, only 8 were eligible for this review. Studies regarding PEI and CHF showed an important incidence of PEI as well as associated malabsorption of nutritional markers(vitamin D, selenium, phosphorus, zinc,folic acid, and prealbumin) in patients with CHF. However, after substitution of pancreatic enzymes, it seems that, at least, loss of appetite was attenuated. On the other side, studies investigating cardiovascular events in patients with CP showed that, in CP cohort, there was a 2.5-fold higher incidence of ACS. In another study, patients with alcohol–induced CP with concomitant type 3 c diabetes had statistically significant higher incidence of carotid atherosclerotic plaques in comparison to patients with diabetes mellitus of other etiologies.Earlier studies demonstrated a marked correlation between the clinical symptoms in CP and chronic coronary insufficiency. Also, statistically significant higher incidence of arterial lesions was found in patients with CP compared to the control group with the same risk factors for atherosclerosis(hypertension,smoking, dyslipidemia). Moreover, one recent study showed that PEI is significantly associated with the risk of cardiovascular events in patients with CP.CONCLUSION Current evidence implicates a possible association between PEI and malnutrition in patients with CHF. Chronic pancreatic tissue hypoxic injury driven by prolonged splanchnic hypoperfusion is likely to contribute to malnutrition and cachexia in patients with CHF. On the other hand, CP and PEI seem to be an independent risk factor associated with an increased risk of cardiovascular events.     

Does body mass index impact on the relationship between systolic blood pressure and cardiovascular Disease? : meta-analysis of 419 488 individuals from the Asia Pacific Cohort Studies Collaboration

Elevated blood pressure and excess body mass index (BMI) are established risk factors for cardiovascular disease (CVD) but controversy exists as to whether, and how, they interact. Methods and Results The interactions between systolic blood pressure and BMI on coronary heart disease, ischemic and hemorrhagic stroke and CVD were examined using data from 419 448 participants (≥30 years) in the Asia-Pacific region. BMI was categorized into 5 groups, using standard criteria, and systolic blood pressure was analyzed both as a categorical and continuous variable. Cox proportional hazard models, stratified by sex and study, were used to estimate hazard ratios, adjusting for age and smoking and the interaction was assessed by likelihood ratio tests. During 2.6 million person-years of follow-up, there were 10 877 CVD events. Risks of CVD and subtypes increased monotonically with increasing systolic blood pressure in all BMI subgroups. There was some evidence of a decreasing hazard ratio, per additional 10 mm Hg systolic blood pressure, with increasing BMI, but the differences, although significant, are unlikely to be of clinical relevance. The hazard ratio for CVD was 1.34 (95% CI, 1.32-1.36) overall with individual hazard ratios ranging between 1.28 and 1.36 across all BMI groups. For coronary heart disease, ischemic stroke, and hemorrhagic stroke, the overall hazard ratios per 10 mm Hg systolic blood pressure were 1.24, 1.46, and 1.65, respectively. Conslusions Increased blood pressure is an important determinant of CVD risk irrespective of BMI. Although its effect tends to be weaker in people with relatively high BMI, the difference is not sufficiently great to warrant alterations to existing guidelines.     

Metabolic syndrome vs. its components for prediction of cardiovascular mortality: A cohort study in Chinese elderly adults

Objectives The predictive value of the metabolic syndrome (MetS) for mortality from all-cause and cardiovascular disease (CVD) in the Chinese population is unclear. The aim of this present study was to compare MetS with its individual components as predictors of mortality in Chinese elderly adults. Methods A cohort of 1,535 subjects (994 men and 541 women) aged 50 years or older was selected from employees of a machinery factory in 1994 and followed until 2009. Cox models were used to estimate the hazard ratios (HRs) predicted by MetS according to the harmonized definition and by its individual components. Results The baseline prevalence of MetS was 28.0% in men and 48.4% in women. During a median follow-up of 15 years, 414 deaths occurred, of these, 153 participants died from CVD. Adjusted for age and gender, the HRs of mortality from all-cause and CVD in participants with MetS were 1.47 (95% confidence interval (CI): 1.20–1.80) and 1.96 (95%CI: 1.42–2.72), respectively, compared with those without MetS. Non-significant higher risk of CVD mortality was seen in those with one or two individual components (HR = 1.22, 95%CI: 0.59–2.50; HR = 1.82, 95%CI: 0.91–3.64, respectively), while a substantially higher risk of CVD mortality only appeared in those with 3, 4, or 5 components (HR = 2.81–3.72), compared with those with no components. On evaluating the MetS components individually, we found that, independent of MetS, only hypertension and impaired glucose predicted higher mortality. Conclusions The number of positive MetS components seems no more informative than classifying (dichotomous) MetS for CVD risks assessment in this Chinese cohort.     

Patients with cardiac disease: Changes observed through last decade in out-patient clinics

AIM: To describe current profile of patients with cardio-vascular disease(CVD) and assessing changes through last decade.METHODS: Comparison of patients with established CVD from two similar cross-sectional registries performed in 1999(n = 6194) and 2009(n = 4639).The types of CVD were coronary heart disease(CHD),heart failure(HF) and atrial fibrillation(AF).Patients were collected from outpatient clinics.Investigators were 80% cardiologist and 20% primary care practitioners.Clinical antecedents,major diagnosis,blood test results and medical treatments were collected from all patients.RESULTS: An increase in all risk factors,except for smoking,was observed;a 54.4% relative increase in BP control was noted.CHD was the most prevalent CVD but HF and AF increased significantly,41.5% and 33.7%,respectively.A significant reduction in serum lipid levels was observed.The use of statins increased by 141.1% as did all cardiovascular treatments.Moreover,the use of angiotensin-renin system inhibitors in patients with HF,beta-blockers in CHD patients or oral anticoagulants in AF patients increased by 83.0%,80.3% and 156.0%,respectively(P < 0.01).CONCLUSION: The prevalence of all cardiovascular risk factors has increased in patients with CVD through last decade.HF and AF have experienced the largest increases.
