The impact of statin therapy on plasma levels of von Willebrand factor antigen. Systematic review and meta-analysis of randomised placebo-controlled trials.
Increased plasma levels of von Willebrand factor antigen (vWF:Ag) are associated with high risk of coronary artery disease. The effect of statin therapy on vWF:Ag levels remains uncertain. Therefore the aim of this meta-analysis was to evaluate the effect of statin therapy on vWF:Ag Levels.
 
Head-to-head comparison of statins versus fibrates in reducing plasma fibrinogen concentrations: A systematic review and meta-analysis.
Several studies suggest differences between fibrates and statins in lowering plasma fibrinogen (Fib) concentrations, but the evidence is not definitive. Therefore, the aim of this meta-analysis of head-to-head randomized trials was to compare the efficacy of statins and fibrates on plasma Fib concentrations.
 
Impact of statin therapy on coronary plaque composition: a systematic review and meta-analysis of virtual histology intravascular ultrasound studies.
Virtual histology intravascular ultrasound (VH-IVUS) imaging is an innovative tool for the morphological evaluation of coronary atherosclerosis. Evidence for the effects of statin therapy on VH-IVUS parameters have been inconclusive. Consequently, we performed a systematic review and meta-analysis to investigate the impact of statin therapy on plaque volume and its composition using VH-IVUS.
 
Statin Therapy and Plasma Coenzyme Q10Concentrations - A Systematic Review and Meta-Analysis of Placebo-Controlled Trials.
Statin therapy may lower plasma coenzyme Q10 (CoQ10) concentrations, but the evidence as to the significance of this effect is unclear. We assessed the impact of statin therapy on plasma CoQ10 concentrations through the meta-analysis of available RCTs.
 
Sleep changes following statin therapy: a systematic review and meta-analysis of randomized placebo-controlled polysomnographic trials.
Statin use might be associated with an increased risk of sleep disturbances including insomnia, but the evidence regarding sleep changes following statin therapy has not been conclusive. Therefore we assessed the impact of statin therapy on sleep changes through a systematic review and meta-analysis of available randomized controlled trials (RCTs).
 
Tibolone decreases Lipoprotein(a) levels in postmenopausal women: A systematic review and meta-analysis of 12 studies with 1009 patients.
Circulating Lp(a) is a recognized risk factor for cardiovascular disease (CVD). Tibolone may lower Lp(a), however, evidence of this effect remains to be confirmed. Meta-analysis suggests a significant Lp(a) reduction following tibolone (by 25.28%). Further studies are warranted to explore the mechanism of this effect. A place of tibolone in individuals at CVD risk needs to be further investigated.
 
Statin therapy reduces plasma endothelin-1 concentrations: A meta-analysis of 15 randomized controlled trials.
Raised plasma endothelin-1 (ET-1) levels may be a risk factor for vascular dysfunction and cardiovascular (CV) disease. This meta-analysis assessed the effect of statins on circulating ET-1 concentrations.
 
A systematic review and meta-analysis of the effect of statins on plasma asymmetric dimethylarginine concentrations.
The impact of statin therapy on plasma asymmetric dimethylarginine (ADMA) levels has not been conclusively studied. Therefore the aim of the meta-analysis was to assess the effect of statins on circulating ADMA levels.
 
Effects of flaxseed supplements on blood pressure: A systematic of review and meta-analysis of controlled clinical trial.
Many experimental and clinical trials suggested that flaxseed might be a potent antihypertensive, but the evidences concerning the effects of flaxseed supplements on blood pressure (BP) has not been fully conclusive. We aimed to assess the impact of the effects of flaxseed supplements on blood pressure through systematic review of literature and meta-analysis of available randomized controlled trials (RCTs).
 
Association between statin use and plasma D-dimer levels. A systematic review and meta-analysis of randomised controlled trials.
D-dimers, specific breakdown fragments of cross-linked fibrin, are generally used as circulating markers of activated coagulation. Statins influence haemostatic factors, but their effect on plasma D-dimer levels is controversial. Therefore, the aim of this meta-analysis was to evaluate the association between statin therapy and plasma D-dimer levels.
 
Lack of efficacy of resveratrol on C-reactive protein and selected cardiovascular risk factors - Results from a systematic review and meta-analysis of randomized controlled trials.
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.
 
In reply - Coenzyme Q10 and Statin-Induced Myopathy.
This is the reply to the letters by Drs Keller and Braillon to our meta-analysis on CoQ(10) and statin-induced myopathy.
 
Effects of Coenzyme Q10 on Statin-Induced Myopathy: A Meta-analysis of Randomized Controlled Trials.
The aim of the meta-analysis was to evaluate the efficacy of coenzyme Q10 (CoQ10) supplementation on statin-induced myopathy. We searched the MEDLINE, Cochrane Library, Scopus, and EMBASE databases (up to May 1, 2014) to identify randomized controlled trials investigating the impact of CoQ10 on muscle pain and plasma creatine kinase (CK) activity as 2 measures of statin-induced myalgia. The results of this meta-analysis of available randomized controlled trials do not suggest any significant benefit of CoQ10 supplementation in improving statin-induced myopathy. Larger, well designed trials are necessary to confirm the findings from this meta-analysis.
 
Analysis of vitamin D levels in patients with and without statin-associated myalgia - A systematic review and meta-analysis of 7 studies with 2420 patients.
Vitamin D (vit D) deficiency may be associated with an increased risk of statin-related symptomatic myalgia in statin-treated patients. The aim of this meta-analysis was to substantiate the role of serum vitamin D levels in statin-associated myalgia. The search included PUBMED, Cochrane Library, Scopus, and EMBASE up to April 1, 2014 to identify studies that investigated the impact of vit D levels in statin-treated subjects with and without myalgia. This meta-analysis provides evidence that low vit D levels are associated with myalgia in patients on statin therapy. Randomized controlled trials are necessary to establish whether vitamin D supplementation reduces the risk for statin-associated myalgia.
 
Statins decrease all-cause mortality only in CKD patients not requiring dialysis therapy—A meta-analysis of 11 randomized controlled trials involving 21,295 participants
Cardiovascular disease (CVD) is the leading cause of morbidity and mortality not only among the general population, but also in patients with chronic kidney disease (CKD). Several clinical trials have demonstrated that inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase (statins) are gaining widespread acceptance as a principal therapy for the primary and secondary prevention of atherosclerosis and CVD.
 
A meta-analysis of the role of statins on renal outcomes in patients with chronic kidney disease. Is the duration of therapy important?
Chronic kidney disease (CKD) is associated with cardiovascular disease (CVD). Beyond established risk factors these patients have additional predictors of CVD such as proteinuria, electrolyte imbalances, inflammation, increased oxidative stress, and endothelial dysfunction that greatly amplify vascular risk. Dyslipidemia is an independent risk factor for the progression of CKD.
 
The effects of statins on blood pressure in normotensive or hypertensive subjects — A meta-analysis of randomized controlled trials
Statins are the lipid lowering treatment of choice for reducing cardiovascular (CV) risk among those with established cardiovascular disease (CVD) or at high risk of incident disease. They inhibit 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase which leads to a decrease in circulating total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) concentrations. Many studies have also investigated the potential role of statins in blood pressure (BP) among patients with hypertension; however, there is still a controversy over whether statin use results in a significant decrease in blood pressure (BP).
 
Effects of statins on lipid profile in chronic kidney disease patients: a meta-analysis of randomized controlled trials
Chronic kidney disease (CKD) is defined as a glomerular filtration rate (GFR)560 mL/min/1.73 m2. The incidence of CKD is rising worldwide, and CKD is associated with increased cardiovascular (CV) morbidity and mortality. CKD with significant albuminuria/proteinuria is frequently associated with substantial alterations of serum lipid levels, most often with elevation in low-density lipoprotein (LDL) particle numbers and triglycerides (TG), and a reduction in high-density lipoprotein cholesterol (HDL-C)2. CKD increases the risk for end stage renal disease (ESRD), atherosclerotic disease, vascular calcification, as well as myocardial infarction, ischemic stroke and death. Even patients in the early stages of CKD are at increased risk of cardiovascular disease (CVD) and a large number of patients with CKD die before developing ESRD.
 
Statins in patients with chronic kidney disease – an attempt at recommendations
Chronic kidney disease (CKD) is associated with cardiovascular disease (CVD) even in the early stages of the disease and a large number of patients die from CVD before developing advanced CKD. Beyond established risk factors (e.g. hypertension, dyslipidaemia, obesity, smoking and diabetes) these patients might also have additional predictors of CVD such as proteinuria, electrolyte imbalances, inflammation, oxidative stress and endothelial dysfunction that amplify vascular risk. Dyslipidaemia is an independent risk factor for the progression of CKD. CKD with significant proteinuria is commonly associated with substantial alteration of serum lipid levels. The most common changes being lowered high density lipoprotein cholesterol (HDL-C) levels and elevated level of triglycerides (TG); hypercholesterolemia per se might be present in around 50% of patients on dialysis.
