The role of anticoagulation in venous thromboembolism primary prophylaxis in patients with malignancy: A systematic review and meta-analysis of randomized controlled trials Venous thromboembolism (VTE) is a common cause of morbidity and mortality among patients with cancer. As such, we conducted a meta-analysis of randomized controlled trials (RCTs) that evaluated anticoagulants as primary prophylaxis against VTE in cancer patients.Pubmed/MEDLINE, Embase, and the Cochrane Library were screened (...) for all RCTs that used anticoagulation therapy in cancer patients for primary prevention of VTE. The primary outcomes were VTE events. Secondary outcomes included all-cause mortality, VTE-related mortality and major bleeding. A random effects model was used to report the risk ratios (RR) with 95% confidence intervals (CIs), and odds ratios (ORs) with Bayesian 95% credible intervals for both direct and network meta-analyses, respectively.Twenty-four RCTs were included totaling 13,338 patients (7197
Meta-Analysis of Oral Anticoagulant Monotherapy as an Antithrombotic Strategy in Patients With Stable Coronary Artery Disease and Nonvalvular Atrial Fibrillation Guidelines recommend oral anticoagulant (OAC) monotherapy without antiplatelet therapy (APT) in patients with nonvalvular atrial fibrillation (AF) with stable coronary artery disease (CAD) of >1 year after myocardial infarction or percutaneous coronary intervention. More evidences are required for the safety and efficacy of OAC
Benefits and Harms of Oral Anticoagulant Therapy in Chronic Kidney Disease: A Systematic Review and Meta-analysis. Effects of oral anticoagulation in chronic kidney disease (CKD) are uncertain.To evaluate the benefits and harms of vitamin K antagonists (VKAs) and non-vitamin K oral anticoagulants (NOACs) in adults with CKD stages 3 to 5, including those with dialysis-dependent end-stage kidney disease (ESKD).English-language searches of MEDLINE, EMBASE, and Cochrane databases (inception (...) to February 2019); review bibliographies; and ClinicalTrials.gov (25 February 2019).Randomized controlled trials evaluating VKAs or NOACs for any indication in patients with CKD that reported efficacy or bleeding outcomes.Two authors independently extracted data, assessed risk of bias, and rated certainty of evidence.Forty-five trials involving 34 082 participants who received anticoagulation for atrial fibrillation (AF) (11 trials), venous thromboembolism (VTE) (11 trials), thromboprophylaxis (6 trials
Left atrial appendage occlusion (LAAO) in patients with atrial fibrillation who have contraindications to oral anticoagulation SHTG Advice | 1 SHTG Advice 06-19 August 2019 In response to an enquiry from the National Advisory Committee for Heart Disease Left atrial appendage occlusion (LAAO) in patients with atrial fibrillation who have contraindications to oral anticoagulation Advice for NHSScotland Left atrial appendage occlusion (LAAO) may be offered to patients with non-valvular atrial (...) fibrillation deemed to be at high risk of ischaemic stroke, who have absolute contraindications to oral anticoagulation with warfarin and direct oral anticoagulants. Prior to undergoing the LAAO procedure, an individual patient risk assessment must be carried out by a multidisciplinary team. The potential future benefits of LAAO, the risks associated with the procedure, and the need for long- term antiplatelet therapy, should be discussed with each patient prior to making a treatment decision.

Extended Anticoagulation for VTE: A Systematic Review and Meta-Analysis The efficacy and safety of direct oral anticoagulants (DOACs) and vitamin K antagonists (VKAs) during extended anticoagulation for a VTE remains largely unknown, especially in terms of potential survival benefit. The goal of this study was to assess the effects of VKAs and DOACs on overall mortality and VTE-related mortality, as well as VTE recurrence and safety.PubMed, EMBASE, and the Cochrane Library were searched from (...) January 1990 through September 2018 for randomized controlled trials evaluating the effect of extended anticoagulants as secondary prevention for VTE compared with placebo. The primary outcome was the specific effects of standard-intensity VKAs and DOACs on overall mortality.Sixteen studies (12,458 patients) were included. DOACs were associated with a reduction in overall (risk ratio [RR], 0.48; 95% CI, 0.27-0.86; P = .01) and VTE-related (RR, 0.36; 95% CI, 0.15-0.89; P = .03) mortality, whereas VKAs
Oral anticoagulants in atrial fibrillation with valvular heart disease and bioprosthetic heart valves Current guidelines endorse the use of non-vitamin K antagonist oral anticoagulants (NOACs) in patients with atrial fibrillation (AF). However, little is known about their safety and efficacy in valvular heart disease (VHD). Similarly, there is a paucity of data regarding NOACs use in patients with a bioprosthetic heart valve (BPHV). We, therefore, performed a network meta-analysis
Oral anticoagulation in patients with chronic kidney disease: A systematic review and meta-analysis Data regarding the efficacy and safety of warfarin and non-vitamin K antagonist oral anticoagulant (NOAC) among patients with chronic kidney disease (CKD) remain scarce.Systematic review and meta-analysis of studies involving patients with CKD treated with oral anticoagulants were conducted to evaluate the following outcomes: ischemic stroke, intracerebral hemorrhage (ICH), combined ischemic (...) and hemorrhagic stroke (strokecombined), stroke or systemic embolism, mortality, and major bleeding events. CKD was defined based on creatinine clearance (CrCl) ranging from mild (CrCl: 60-89 mL/min), moderate (CrCl: 30-59 mL/min), to severe (CrCl: 15-29 mL/min).Fifteen studies (7 comparing NOAC vs warfarin and 8 comparing warfarin vs no anticoagulant) were identified comprising 78,053 patients. Warfarin (vs no anticoagulant) was associated with reduced risk of ischemic stroke (risk ratio [RR] = 0.68; 95
Meta-Analysis of Direct-Acting Oral Anticoagulants Compared With Warfarin in Patients >75 Years of Age Older patients with atrial fibrillation (AF) are at higher risk of thromboembolic events and oral anticoagulant (OAC)-related bleeding complications. This meta-analysis evaluates the efficacy and safety of direct-acting OACs (DOACs) compared with warfarin in older patients with nonvalvular AF. PubMed, Embase, and Cochrane Central databases were searched for randomized controlled trials
Incident Atrial Fibrillation, Dementia and the Role of Anticoagulation: A Population-Based Cohort Study Atrial fibrillation (AF) is associated with dementia. Anticoagulation may modify this relationship, but it is unclear if this is due to stroke reduction alone. Age- and sex-matched individuals from the U.K. Clinical Practice Research Datalink (2008-2016) with and without an incident diagnosis of AF were followed for a new dementia diagnosis. We estimated adjusted hazard ratios (aHRs (...) ) for incident dementia diagnosis in the AF cohort, overall and stratified by anticoagulation status, using the matched non-AF cohorts as reference. We performed a sensitivity analysis excluding individuals with stroke/transient ischaemic attack (TIA) before the observation period. Over 193,082 person-years (mean follow-up 25.7 ± 0.1 months), 347/15,276 AF (2.3%) and 1,085/76,096 non-AF (1.4%) were newly diagnosed with dementia (aHR, 1.31, 95% confidence interval, 1.15-1.49). The AF group had more co
Anticoagulation therapy in heart failure and sinus rhythm: a systematic review and meta-analysis Heart failure is a prothrombotic state, and it has been hypothesised that thrombosis and embolism cause non-fatal and fatal events in heart failure and reduced ejection fraction (HFrEF). We sought to determine the effect of anticoagulant therapy on clinical outcomes in patients with HFrEF who are in sinus rhythm.We conducted an updated systematic review and meta-analysis to examine the effect (...) of anticoagulation therapy in patients with HFrEF in sinus rhythm. Our analysis compared patients randomised to anticoagulant therapy with those randomised to antiplatelet therapy, placebo or control, and examined the endpoints of all-cause mortality, (re)hospitalisation for worsening heart failure, non-fatal myocardial infarction, non-fatal stroke of any aetiology and major haemorrhage.Five trials were identified that met the prespecified search criteria. Compared with control therapy, anticoagulant treatment
Resumption of anticoagulant therapy after anticoagulant-related gastrointestinal bleeding: A systematic review and meta-analysis Oral anticoagulation (OAC) is permanently discontinued in up to 50% of patients following a gastrointestinal (GI) bleed. A previous meta-analysis showed a reduced risk of thromboembolism and death, and a non-statistically significant increased risk of re-bleeding associated with resumption. We conducted an updated meta-analysis to determine the risks of recurrent GI
Direct oral anticoagulants in patients with venous thromboembolism and thrombophilia: a systematic review and meta-analysis Essentials We investigated direct oral anticoagulant (DOAC) use in venous thromboembolism and thrombophilia. A comprehensive search identified 10 studies, 8 of which were included in a meta-analysis. DOACs were overall safe and effective in patients with venous thromboembolism and thrombophilia. Efficacy/safety of DOACs was maintained in low-risk antiphospholipid syndrome (...) patient subgroup. SUMMARY: Background Direct oral anticoagulants (DOACs) are increasingly used in acute and long-term treatment of venous thromboembolism (VTE). However, their role in management of thrombophilia-associated VTE is controversial. Methods Through a comprehensive search on MEDLINE, Cochrane Library, and Clinicaltrials.gov, we identified 10 eligible studies, 8 of which reporting data on 1994 thrombophilia patients were included in a random-effects meta-analysis. Eligible studies were phase
Improving the Prescription of Oral Anticoagulants in Atrial Fibrillation: A Systematic Review Oral anticoagulant (OAC) prescription for stroke prevention in atrial fibrillation (AF) patients frequently does not follow current guidelines, with underuse in patients at high risk of stroke and substantial overuse in those at low risk. This review aims to systematically evaluate the effectiveness of interventions to improve appropriate OAC prescription in eligible AF patients for stroke prevention
