Oral Anticoagulant Treatment

AbstractGiven the aging population, the burden of age-dependent diseases is growing. Despite this, elderly patients are often underrepresented in clinical trials and little data are available on current anticoagulant management and outcomes in this unique population, especially those aged 90 years or older. There is uncertainty, and a fear of “doing harm,” that often leads to de-prescription of antithrombotic agents in nonagenarian patients. Decision-making concerning the use of anticoagulant treatment needs to balance the risk of thrombotic events against the risk of major bleeding, especially intracranial hemorrhage. In this perspective, the development of direct oral anticoagulants (DOACs), acting as direct and selective inhibitors of a specific step or enzyme of the coagulation cascade, has dramatically changed oral anticoagulant treatment. In fact, given the lower incidence of intracranial hemorrhage, the favorable overall efficacy and safety, and the lack of routine monitoring, DOACs are the currently recommended anticoagulant agents for the treatment of both atrial fibrillation and venous thromboembolism even in very elderly patients. However, given the limited data available on the management of anticoagulation in nonagenarians, a few unanswered questions remain. In this review, we focused on recent evidence for anticoagulant treatment in atrial fibrillation and venous thromboembolism along with management of anticoagulation-related bleeding in nonagenarians.

Composite Outcome

Introduction: Randomized controlled trials that compared direct oral anticoagulants (DOACs) to vitamin K antagonists (VKA) for the treatment of venous thromboembolism (VTE), demonstrated both efficacy and safety of DOACs. The aim of the current study was to compare DOACs to VKA for the treatment of VTE in the elderly, in a real-life setting. Methods: A retrospective cohort study was performed in Rabin Medical Center encompassing a 7-year period. Hospitalized patients >65 years, with a diagnosis of VTE discharged with DOACs or VKA were included. The primary outcome was a composite of all-cause mortality, major bleeding, recurrent VTEs and hospitalizations throughout the follow-up period of one year. Results: A total of 603 patients were included in the final analysis. The mean age was 79.6 ± 8.5 years. The primary composite outcome occurred in 74.6% and 56.7% of the patients in the VKA group and DOACs group, respectively, hazard ratio 0.59, 95% confidence interval 0.46 to 0.76, in favor of the DOACs group. In a matched cohort analysis, the results were the same as the original analysis. Conclusion: In the elderly population, treatment of VTE with DOACs was associated with a lower rate of the composite outcome. DOACs are safe and effective for elderly patients with VTE.

Abstract Funding Acknowledgements Type of funding sources: None. Background- Low molecular weight heparin (LMWH) and direct oral anticoagulants (DOACs) have been proven to be more effective in the management of venous thromboembolism (MVTE). The efficacy and safety of LMWH or DOACs in treatment of recurrent or malignancy induced VTE is not studied in literature. Objective To compare the efficacy and safety of LMWH and  DOACs in the management of malignancy induced  VTE Methods- Electronic databases ( PubMed, Embase, Scopus, Cochrane) were searched from inception to November  28th, 2020. Dichotomous data was extracted for prevention of VTE and risk of major bleeding in patients taking either LMWH or DOACs. Unadjusted odds ratios (OR) were calculated from dichotomous data using Mantel Haenszel (M-H) random-effects with statistical significance to be considered if the confidence interval excludes 1 and p < 0.05.  Results- Three studies with 2607 patients (DOACs n = 1301 ; LMWH n = 1306) were included in analysis. All the study population had active cancer of any kind diagnosed within the past 6 months. Average follow-up period for each trial was 6 months. Patients receiving DOACs have a lower odds of recurrence of MVTE as compared to LMWH( OR 1.56; 95% CI 1.17-2.09; P = 0.003, I2 = 0). There was no significant difference in major bleeding among patients receiving LMWH or DOACs  (OR-0.71, 95%CI 0.46-1.10, P = 0.13, I2 = 22%) (Figure 1). We had no publication bias in our results (Egger’s regression p > 0.05). Conclusion- DOACs are superior to LMWH in prevention of MVTE and have similar major bleeding risk as that of LMWH.

The Difference

AbstractTreatment options for patients with venous thromboembolism (VTE) include warfarin and direct oral anticoagulants (DOACs). Although DOACs are easier to administer than warfarin and do not require routine laboratory monitoring, few studies have directly assessed whether patients are more satisfied with DOACs. We surveyed adults from two large integrated health systems taking DOACs or warfarin for incident VTE occurring between January 1, 2015 and June 30, 2018. Treatment satisfaction was assessed using the validated Anti-Clot Treatment Scale (ACTS), divided into the ACTS Burdens and ACTS Benefits scores; higher scores indicate greater satisfaction. Mean treatment satisfaction was compared using multivariable linear regression, adjusting for patient demographic and clinical characteristics. The effect size of the difference in means was calculated using a Cohen’s d (0.20 is considered a small effect and ≥ 0.80 is considered large). We surveyed 2217 patients, 969 taking DOACs and 1248 taking warfarin at the time of survey. Thirty-one point five percent of the cohort was aged ≥ 75 years and 43.1% were women. DOAC users were on average more satisfied with anticoagulant treatment, with higher adjusted mean ACTS Burdens (50.18 v. 48.01, p < 0.0001) and ACTS Benefits scores (10.21 v. 9.84, p = 0.046) for DOACs vs. warfarin, respectively. The magnitude of the difference was small (Cohen’s d of 0.29 for ACTS Burdens and 0.12 for ACTS Benefits). Patients taking DOACs for venous thromboembolism were on average more satisfied with anticoagulant treatment than were warfarin users, although the magnitude of the difference was small.

This study assessed epidemiologic data and clinical outcomes, including venous thromboembolism (VTE) recurrence and bleeding events, in patients with cancer-associated VTE, and assessed factors associated with clinical outcomes. Data were extracted from retrospective medical-chart review of adult patients diagnosed with cancer-associated deep vein thrombosis or pulmonary embolism who received anticoagulation treatment for ≥3 months. Patients were classified by: low-molecular-weight heparin (LMWH), direct oral anticoagulants (DOACs), and other anticoagulants. First VTE recurrence and bleeding events, and factors associated with their occurrence, were assessed during the initial 6 months of treatment. Overall, 623 patients (age: 63.7 ± 11.3 years, 49.3% male) were included (119, 132, and 372 patients in LMWH, DOACs and other anticoagulants groups, respectively). The cumulative 6-month incidence of VTE recurrence was 16.6% (total), 8.3% (LMWH), 16.7% (DOACs), and 20.7% (other); respective bleeding events were 22.5%, 11.0%, 12.3%, and 30.7%). VTE recurrence and bleeding rates differed only between LMWH and other anticoagulants (HR 2.4, 95% CI: 1.2-5.0 and 3.6, 1.9-6.8, respectively). These results highlight the importance of initial VTE treatment choice for preventing VTE recurrence and bleeding events. LMWH or DOACs for ≥3 months can be considered for effective VTE management in cancer patients.
