Lack of efficacy of resveratrol on C-reactive protein and selected cardiovascular risk factors — Results from a systematic review and meta-analysis o…
2015
Introduction: Numerous studies have suggested that oral supplementation with resveratrol exerts cardioprotective effects, but evidence of the effects on C-reactive protein (CRP) plasma levels and other cardiovascular (CV) risk factors is inconclusive. Therefore, we performed a meta-analysis to evaluate the efficacy of resveratrol supplementation on plasma CRP concentrations and selected predictors of CV risk. Methods:The searchincludedPUBMED,Cochrane Library,Web ofScience,Scopus,andEMBASE(up toAugust31, 2014) to identify RCTs investigating the effects of resveratrol supplementation on selected CV risk factors. Quantitative data synthesis was performed using a random-effects model, with weig…
Atorvastatin in stable angina patients lowers CCL2 and ICAM1 expression: Pleiotropic evidence from plasma mRNA analyses
2013
Objective: Statin pleiotropy is still an evolving concept, and the lack of clarity on this subject is due at least in part to the lack of a definitive biomarker for statin pleiotropy. Using plasma mRNA analysis as a novel research tool for the non-invasive in vivo assessment of gene expression in vascular beds, we hypothesised that atorvastatin lowers the plasmamRNA level from statin pleiotropy-target genes, and the reduction is independent of the reduction of low-density lipoprotein cholesterol (LDL-C). Design and methods: Forty-four patients with stable angina received atorvastatin therapy (20 mg/day, 10 weeks). Plasma chemokine (C-C motif) ligand 2 (CCL2) and intercellular adhesion molec…
Dietary fat interacts with the -514CT polymorphism in the hepatic lipase gene promoter on plasma lipid profiles in a multiethnic Asian population: th…
2003
We have previously reported an interaction between -514CT polymorphism at the hepatic lipase (HL) gene and dietary fat on high-density lipoprotein-cholesterol (HDL-C) metabolism in a representative sample of white subjects participating in the Framingham Heart Study. Replication of these findings in other populations will provide proof for the relevance and consistency of this marker as a tool for risk assessment and more personalized cardiovascular disease prevention. Therefore, we examined this gene-nutrient interaction in a representative sample of Singaporeans (1324 Chinese, 471 Malays and 375 Asian Indians) whose dietary fat intake was recorded by a validated questionnaire. When no str…
Blood pressure and LDL-cholesterol targets for prevention of recurrent strokes and cognitive decline in the hypertensive patient : design of the Euro…
2014
BACKGROUND AND OBJECTIVES:: The SBP values to be achieved by antihypertensive therapy in order to maximize reduction of cardiovascular outcomes are unknown; neither is it clear whether in patients with a previous cardiovascular event, the optimal values are lower than in the low-to-moderate risk hypertensive patients, or a more cautious blood pressure (BP) reduction should be obtained. Because of the uncertainty whether 'the lower the better' or the 'J-curve' hypothesis is correct, the European Society of Hypertension and the Chinese Hypertension League have promoted a randomized trial comparing antihypertensive treatment strategies aiming at three different SBP targets in hypertensive pati…
Cytomegalovirus infection with interleukin-6 response predicts cardiac mortality in patients with coronary artery disease.
2001
Background —Prospective data relating previous exposure to cytomegalovirus (CMV) to the risk of cardiac mortality are controversial. We investigated the effect of previous exposure to CMV infection on the risk of future cardiac disease–related death in relation to an underlying inflammatory response. Methods and Results —Coronary angiography was performed in 1134 subjects, and 989 patients with documented coronary artery disease were studied prospectively. CMV-IgG titers and interleukin (IL)-6 levels were measured before angiography. Increasing titers of CMV correlated with the elevation of IL-6 levels ( P <0.001) after adjustment for possible confounders. All patients were followed up …
Results of the Dyslipidemia International Study (DYSIS)-Middle East: Clinical Perspective on the Prevalence and Characteristics of Lipid Abnormalitie…
2013
BACKGROUND: Therapeutic intervention with low-density lipoprotein cholesterol-lowering agents known as statins has been demonstrated to reduce cardiovascular risk. However, many patients on statin treatment have persistent dyslipidemia and remain at a high risk of cardiovascular disease. Therefore, the objective of this study was to assess the frequency of lipid abnormalities in patients receiving chronic statin treatment. METHODS: As part of an international, cross-sectional, observational study, DYSIS-Middle East enrolled 2,182 patients in the United Arab Emirates (UAE), Saudi Arabia, Lebanon and Jordan. All patients were over 45 years of age and had been on statin treatment for at least …
Cholesterol levels and risk of hemorrhagic transformation after acute ischemic stroke.
2011
<i>Background:</i> The association between cholesterol levels and hemorrhagic transformation (HT) is still controversial. Studies investigating this issue are influenced by treatments as some are characterized by a higher risk of HT. The aim of our study was to evaluate, in a hospital-based series of patients not treated with thrombolysis, the relationship between cholesterol levels and HT. <i>Methods:</i> We retrospectively collected information about total cholesterol (TC) and low-density lipoprotein cholesterol (LDLC) levels at admission in a consecutive series of 240 patients with anterior ischemic stroke (IS). The TC and LDLC levels were arranged in 3 groups acc…
Alterations of a Cellular Cholesterol Metabolism Network Are a Molecular Feature of Obesity-Related Type 2 Diabetes and Cardiovascular Disease
2015
Obesity is linked to type 2 diabetes (T2D) and cardiovascular diseases; however, the underlying molecular mechanisms remain unclear. We aimed to identify obesity-associated molecular features that may contribute to obesity-related diseases. Using circulating monocytes from 1,264 Multi-Ethnic Study of Atherosclerosis (MESA) participants, we quantified the transcriptome and epigenome. We discovered that alterations in a network of coexpressed cholesterol metabolism genes are a signature feature of obesity and inflammatory stress. This network included 11 BMI-associated genes related to sterol uptake (↑LDLR, ↓MYLIP), synthesis (↑SCD, FADS1, HMGCS1, FDFT1, SQLE, CYP51A1, SC4MOL), and efflux (↓A…
Impact of Lower Versus Higher LDL Cholesterol Targets on Cardiovascular Events After Ischemic Stroke in Patients With Diabetes
2021
International audience; After an ischemic stroke with evidence of atherosclerosis, lipid-lowering treatment with a target LDL cholesterol of <70 mg/dL compared with 100 ± 10 mg/dL reduced the risk of subsequent cardiovascular events. In this analysis, we explored the effect in the subgroup of patients with diabetes compared with the subgroup without, as well as in those with newly diagnosed diabetes. Patients with ischemic stroke in the previous 3 months or transient ischemic attack within the previous 15 days and evidence of cerebrovascular or coronary artery atherosclerosis were randomly assigned at a 1:1 ratio to a target LDL cholesterol of <70 mg/dL or 100 ± 10 mg/dL using statin or eze…
Double-blind, crossover study of the clinical efficacy and the hemorheological effects of pentoxifylline in patients with occlusive arterial disease …
1984
The effect of a 3 month daily administration of 800 mg pentoxifylline (Trental 400 bds) or placebo was assessed under double blind crossover design in 18 patients (12 males and 6 females) with peripheral occlusive arterial disease in respect of painfree walking distance and various hemorheological and hemostasiological variables, platelet aggregation, serum cholesterol and triglycerides. In first treatment period walking distance significantly increased with pentoxifylline by 46% from baseline 121 ± 15 m and by 4% with placebo from baseline 134 ± 18 m. Pentoxifylline administration furthermore yielded significant decrease in whole blood and plasma viscosity and significant increase in eryt…
