BACKGROUND: Evolocumab (AMG 145), a PCSK9 inhibitor, has been shown to decrease low-density lipoprotein cholesterol (LDL-C) levels. Doses of 140mg administered every 2weeks (Q2W) and 420mg administered every 4weeks (Q4W) are widely used, and both dosing schedules were effective in clinical trials. However, some researchers have speculated that 140mg Q2W administration has equal or even greater efficacy. This meta-analysis was performed to assess the differences in efficacy and safety between the two doses...

Background: Attempts to reduce the burden of vascular disease in advanced chronic kidney disease (CKD) by control of lipids have not been as successful as predicted. Aim: : To determine the extent to which the effectiveness of statins varies by kidney class. Design: Meta-analysis. Methods: We selected randomized trials of statin vs. placebo that gave outcomes for CKD3 (eGFR 30-59 ml/min), CKD4 (eGFR 15-29 ml/min), CKD5 (eGFR < 15 ml/min)/5D(dialysis) and transplant patients separately...

Proprotein convertase subtilisin/kexin9 monoclonal antibodies (PCSK9-mAb) have been studied intensively to identify their effect in lowering levels of low density lipoprotein cholesterol (LDL-C). However, the applicable target of PCSK9-mAbs remains inconclusive so far. Therefore, this first meta-analysis was carried out to clarify the therapeutic efficacy and safety of PCSK9-mAbs on the potential patients: familial hypercholesterolemia and statin-intolerant patients. All randomized controlled trials that met the search terms were retrieved in multiple databases...

OBJECTIVES: This study sought to determine prognostic value of nonobstructive coronary artery disease (CAD) for atherosclerotic cardiovascular disease (ASCVD) events and to determine whether incorporation of this information into the pooled cohort equation reclassifies recommendations for statin therapy as defined by the 2013 guidelines for cholesterol management of the American College of Cardiology and American Heart Association (ACC/AHA). BACKGROUND: Detection of nonobstructive CAD by coronary computed tomography angiography may improve risk stratification and permit individualized and more appropriate allocation of statin therapy...

The development of coronary revascularization has dramatically improved early cardiovascular outcomes in patients with acute coronary syndrome (ACS). However, patients who have experienced myocardial infarction (MI) are at high risk of recurrence of cardiovascular events compared with those who are healthy or have stable coronary artery disease. Acute coronary events induce further inflammatory responses and plaque vulnerability in either a coronary culprit or whole vessels. The majority of data have supported the importance of coronary risk management to prevent secondary events...

The global epidemic of obesity and diabetes underscores the urgency to develop strategies to prevent cardiovascular (CV) disease in this vulnerable population. Clinical guidelines are intended to help the clinician manage these patients, but guidelines are often discordant among professional organizations and not always evidence based. Clinicians must rely upon the best available evidence, and therefore we critically reviewed the evidence behind the American Diabetes Association (ADA) 2016 guidelines on the prevention of CV disease in diabetes...

BACKGROUND: Statins are one of the most common medications for stroke prevention. Increasing evidence indicates that the effect of statins against stroke may depend on the optimal adherence of the patients to the long-term therapies. However, the magnitude of the association between statin adherence and the risk of stroke has not been determined. OBJECTIVE: We conducted a dose-response meta-analysis to investigate the association between statin adherence and the risk of stroke...

In the treatment or secondary prevention of cardiovascular disease (CVD), there is general consensus that the absolute benefits of aspirin far outweigh the absolute risks. Despite evidence from randomized trials and their meta-analyses, older adults, defined as aged 65 years or older, are less likely to be prescribed aspirin than their middle-aged counterparts. In primary prevention, the optimal utilization of aspirin is widely debated. There is insufficient randomized evidence among apparently healthy participants at moderate to high risk of a first CVD event, so general guidelines seem premature...

The hydroxyl-methyl-glutaryl-coenzyme-A (HMG-CoA) reductase inhibitors of statin action are very effective and safe drugs, and they are widely used for the treatment of hyperlipidemia and the prevention of primary and secondary cardiovascular diseases (CVDs). However, recent meta-analyses of previous studies done with statins have shown that these drugs could induce new onset diabetes mellitus (NODM), especially in subjects prone to diabetes: obese, females, older age, Asian descent, and those with pre-diabetes or the metabolic syndrome...

BACKGROUND: The benefits of statin therapy are significantly compromised by noncompliance. Although elderly patients may have particular challenges with medication adherence and persistence, previous reviews on statin adherence have not focused on this population. Additionally, comparisons of adherence and persistence specific to statin indication (primary or secondary prevention) have not been thoroughly explored. OBJECTIVE: We aim to assess the extent of, and factors associated with, adherence and persistence to statin therapy among older populations (aged ≥65 years)...

PURPOSE OF REVIEW: Statins reduce cholesterol synthesis and promote low-density lipoprotein clearance from circulation. Beyond their cholesterol-lowering action, statins may interfere with haemostasis. This review aims to provide an update on the impact of statin treatment on markers of haemostasis and platelet function and on thrombosis-related outcomes. RECENT FINDINGS: Different coagulation factors are modulated by statins, leading to inhibition of coagulation and increased fibrinolysis...

BACKGROUND: The effect of preoperative statin treatment (PST) on the risk of postoperative acute kidney injury (AKI) after cardiac surgery remains controversial. We performed a meta-analysis of randomised controlled trials (RCT) to investigate whether PST could improve the renal outcomes in patients undergoing cardiac surgery. METHODS: We conducted a comprehensive search on PubMed, Embase and Cochrane Central Register of Controlled Trials. Randomised controlled trials which reported incidence of AKI and renal replacement treatment (RRT), mean change of serum creatine (SCr) and C-reactive protein (CRP), length of stay in intensive care unit (LOS-ICU) and hospital (LOS-HOS) were included...

Background -Relative risk reduction with statin therapy has been consistent across nearly all subgroups studied to date. However, in analyses of two randomized controlled primary prevention trials (ASCOT and JUPITER), statin therapy led to a greater relative risk reduction among a subgroup at high genetic risk. Here, we sought to confirm this observation in a third primary prevention randomized controlled trial. Additionally, we assessed if those at high genetic risk had a greater burden of subclinical coronary atherosclerosis...
