<p>Thrombotic and embolic events contribute to the morbidity and mortality associated to Chronic Heart Failure (HF). Differently from patients with atrial fibrillation (AF) and HF, in which the benefit of anticoagulation is well documented, the use of these drugs in those with HF in sinus rhythm (without AF history) is controversial. In this systematic review from the Cochrane Collaboration, the authors evaluated the benefits and risks associated with oral anticoagulation (versus placebo) in this population. Only 2 randomized controlled trials were published (one with open-label design) enrolling a total of 324 patients. The results of the meta-analysis based on the best available evidence do not support the systematic use of oral anticoagulants in patients with HF and sinus rhythm for preventing death (overall or cardiovascular) or non-fatal cardiovascular events. Furthermore the major bleeding risk was significantly increased.<br /><strong>Keywords:</strong> Anticoagulation; Heart Failure; Sinus Rhythm; Systematic Review.</p>

Background: The evidence indicates that the optimal observation period following renal biopsy ranges between 6 and 8 h. This systematic review and meta-analysis explored whether differences exist in the complication rates of renal biopsies performed in outpatient and inpatient settings. Methods: We searched the MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews from 1985 to February 2020. Two reviewers independently selected studies evaluating the bleeding risk from renal biopsies performed in outpatient and inpatient settings and reviewed their full texts. The primary and secondary outcomes were risks of bleeding and major events (including mortality) following the procedure, respectively. Subgroup analysis was conducted according to the original study design (i.e., prospective or retrospective). Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using a random effect meta-analysis. Heterogeneity was assessed using the I2 test. Results: Data from all 10 eligible studies, which included a total of 1801 patients and 203 bleeding events, were included for analysis. Renal biopsies in outpatient settings were not associated with a higher bleeding risk than those in inpatient settings (OR = 0.81; 95% CI, 0.59–1.11; I2 = 0%). The risk of major events was also comparable across both groups (OR = 0.45; 95% CI, 0.16–1.29; I2 = 4%). Conclusions: Similar rates of bleeding and major events following renal biopsy in outpatient and inpatient settings were observed.

Abstract Introduction There is conflicting evidence on the risk–benefit ratio of oral anticoagulants (OAC) in heart failure (HF) patients without atrial fibrillation. We aimed to evaluate the efficacy and safety of OAC in HF patients in sinus rhythm. Methods A systematic literature search was conducted using PubMed and Embase. We included randomized controlled trials (RCT) and cohort studies, comparing OAC with antiplatelet or no treatment/placebo in patients with HF. Outcomes evaluated were stroke, myocardial infarction (MI), all-cause mortality, and major bleeding. Results Five RCTs and three cohort studies were included. OAC was associated with a reduced risk of ischemic stroke when compared with no treatment/placebo (odds ratio [OR] = 0.67, 95% confidence interval [CI]: [0.47, 0.94]) and antiplatelet therapy (OR = 0.55, 95% CI: [0.37, 0.81]). No significant reduction was found in MI, when OAC was compared with no treatment/placebo (OR = 0.82, 95% CI: [0.63, 1.07]) or antiplatelet therapy (OR = 1.04, 95% CI: [0.60, 1.81]). The all-cause mortality analysis showed no significant reduction when comparing OAC with no treatment/placebo (OR = 0.99, 95% CI: [0.87, 1.12]) or antiplatelet therapy (OR = 1.00, 95% CI: [0.86, 1.16]). The nonsignificant effect of OAC on all-cause mortality was supported by a meta-analysis of the three cohort studies (OR = 1.02, 95% CI: [0.75, 1.38]). Patients treated with OAC had a significantly higher risk of major bleeding than patients receiving antiplatelet therapy (OR = 2.16, 95% CI: [1.55, 3.00]) and a numerically higher risk when compared with no treatment/placebo (OR = 2.38, 95% CI: [0.87, 6.49]). Conclusion The present study does not support the routine use of OAC in patients with HF in sinus rhythm.

Background Previous meta-analyses of randomized controlled trials of oral anticoagulation in patients with heart failure and sinus rhythm reported reduced stroke risk and increased bleeding risk compared to antiplatelets or placebo. However, the effect estimates may be subject to imprecision, as all included trials were prematurely terminated; stroke was not the primary outcome and overall results were primarily driven by a single trial. Recently, new trial data became available. Aim To provide more accurate estimates of the effect of oral anticoagulation on stroke risk in heart failure patients with sinus rhythm by systematic review and meta-analysis of available randomized controlled trials including recently published evidence. Methods We searched PubMed and Scopus for full-text articles of randomized controlled trials of oral anticoagulation versus antiplatelet or placebo in heart failure patients with sinus rhythm published between inception and 28 August 2018. The outcomes assessed were any stroke, major bleeding, and death. Results In five trials (9490 patients; 21,067 patient-years), oral anticoagulation-treated patients had lower stroke risk (odds ratio (OR) 0.60, 95%CI: 0.46–0.78, absolute-risk-reduction: 1.3%, number-needed-to-treat: 77), higher major bleeding risk (OR: 1.92, 95%CI: 1.51–2.45, absolute-risk-increase: 2.0%, number-needed-to-harm: 50), and no significant difference in death rates (OR: 0.90, 95%CI: 0.73–1.11) compared to antiplatelets or placebo. Conclusions In the largest meta-analysis to date, oral anticoagulation is associated with a considerable reduction of stroke risk, which is offset by a significant increase in major bleeding risk. For every 1000 patients treated with oral anticoagulation rather than antiplatelet or no antithrombotic treatment for 2.21 years, 13 strokes are prevented but 20 additional major hemorrhages occur, without significant difference in death rates.
