Triple Antithrombotic Therapy

Guidelines for antithrombotic therapy are complex, especially if a patient has several indications that require antithrombotic therapy. In general, no patient should receive lifelong double or triple antithrombotic therapy. In this overview, we outline the most common indications for mono, double and triple antithrombotic therapy; the preferred antithrombotic therapy and the recommended duration of therapy. Both antiplatelet therapy and therapeutic anticoagulation therapy with vitamin K antagonists or direct oral anticoagulants were included. European guidelines were used or, if no European guidelines were available, the Dutch guidelines were used.

Active Cancer

AbstractAtrial fibrillation (AF) is commonly diagnosed in the setting of active cancer. Because of an increased risk of either thromboembolic events or bleeding, the decision to initiate therapeutic anticoagulation in patients with active cancer can be challenging. Moreover, little is still known about the optimal anticoagulation therapy in the setting of AF and cancer, and no guidelines are as yet available. Considering that nonvitamin K antagonist oral anticoagulants (NOACs) are recommended as alternatives to vitamin K antagonists for stroke prevention in AF patients with CHA2DS2-VASc score ≥2, the authors performed a systematic review of the current literature to describe the efficacy and safety of NOACs in AF patients with malignancy.

Pharmacological Cardioversion

The therapeutic dilemma between rhythm and rate control in the management of atrial fibrillation (AF) is still unresolved and electrical or pharmacological cardioversion (CV) frequently represents a useful strategy. The most recent guidelines recommend anticoagulation according to individual thromboembolic risk. Vitamin K antagonists (VKAs) have been routinely used to prevent thromboembolic events. Non-vitamin K antagonist oral anticoagulants (NOACs) represent a significant advance due to their more predictable therapeutic effect and more favorable hemorrhagic risk profile. In hemodynamically unstable patients, an emergency electrical cardioversion (ECV) must be performed. In this situation, intravenous heparin or low molecular weight heparin (LMWH) should be administered before CV. In patients with AF occurring within less than 48 h, synchronized direct ECV should be the elective procedure, as it restores sinus rhythm quicker and more successfully than pharmacological cardioversion (PCV) and is associated with shorter length of hospitalization. Patients with acute onset AF were traditionally considered at lower risk of thromboembolic events due to the shorter time for atrial thrombus formation. In patients with hemodynamic stability and AF for more than 48 h, an ECV should be planned after at least 3 weeks of anticoagulation therapy. Alternatively, transesophageal echocardiography (TEE) to rule out left atrial appendage thrombus (LAAT) should be performed, followed by ECV and anticoagulation for at least 4 weeks. Theoretically, the standardized use of TEE before CV allows a better stratification of thromboembolic risk, although data available to date are not univocal.

Proportional Incidence

Abstract Background Falls from standing are common in the elderly and are associated with a significant risk of bleeding. We have compared the proportional incidence of bleeding complications in patients on either direct oral anticoagulants (DOAC) or vitamin K antagonists (VKA). Methods Our retrospective cohort study compared elderly patients (≥65 years) on DOAC or VKA oral anticoagulation who presented at the study site – a Swiss university emergency department (ED) – between 01.06.2012 and 01.07.2017 after a fall. The outcomes were the proportional incidence of any bleeding complication and its components (e.g. intracranial haemorrhage), as well as procedural and clinical parameters (length of hospital stay, admission to intensive care unit, in-hospital-mortality). Uni- and multivariable analyses were used to compare the studied outcomes. Results In total, 1447 anticoagulated patients were included – on either VKA (n = 1021) or DOAC (n = 426). There were relatively more bleeding complications in the VKA group (n = 237, 23.2%) than in the DOAC group (n = 69, 16.2%, p = 0.003). The difference persisted in multivariable analysis with 0.7-fold (95% CI: 0.5–0.9, p = 0.014) lower odds for patients under DOAC than under VKA for presenting with any bleeding complications, and 0.6-fold (95% 0.4–0.9, p = 0.013) lower odds for presenting with intracranial haemorrhage. There were no significant differences in the other studied outcomes. Conclusions Among elderly, anticoagulated patients who had fallen from standing, those under DOACs had a lower proportional incidence of bleeding complications in general and an even lower incidence of intracranial haemorrhage than in patients under VKAs.

Cancer History

Objective: To describe major events at follow up in octogenarian patients with atrial fibrillation (AF) according to anticoagulant treatment: direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs). Methods: A total of 578 anticoagulated patients aged ≥80 years with AF were included in a prospective, observational, multicenter study. Basal features, embolic events (stroke and systemic embolism), severe bleedings, and all-cause mortality at follow up were investigated according to the anticoagulant treatment received. Results: Mean age was 84.0 ± 3.4 years, 56% were women. Direct oral anticoagulants were prescribed to 123 (21.3%) patients. Compared with 455 (78.7%) patients treated with VKAs, those treated with DOACs presented a lower frequency of permanent AF (52.9% vs 61.6%, P = .01), cancer history (4.9% vs 10.9%, P = .046), renal failure (21.1% vs 32.2%, P = .02), and left ventricular dysfunction (2.4% vs 8.0%, P = .03); and higher frequency of previous stroke (26.0% vs 16.6%, P = .02) and previous major bleeding (8.1% vs 3.6%, P = .03). There were no significant differences in Charlson, CHA2DS2VASc, nor HAS-BLED scores. At 3-year follow up, rates of embolic events, severe bleedings, and all-cause death (per 100 patients-year) were similar in both groups (DOACs vs VKAs): 0.34 vs 1.35 ( P = .15), 3.45 vs 4.41 ( P = .48), and 8.2 vs 11.0 ( P = .18), respectively, without significant differences after multivariate analysis (hazard ratio [HR]: 0.25, 95% confidence interval [CI]: 0.03-1.93, P = .19; HR: 0.88, 95% CI: 0.44-1.76, P = .72 and HR: 0.84, 95% CI: 0.53-1.33, P = .46, respectively). Conclusion: In this “real-world” registry, the differences in major events rates in octogenarians with AF were not statistically significant in those treated with DOACs versus VKAs.

Pharmacological Cardioversion

For many patients with symptomatic atrial fibrillation, cardioversion is performed to restore sinus rhythm and relieve symptoms. Cardioversion carries a distinct risk for thromboembolism which has been described to be in the order of magnitude of 1 to 3 %. For almost five decades, vitamin K antagonist therapy has been the mainstay of therapy to prevent thromboembolism around the time of cardioversion although not a single prospective trial has formally established its efficacy and safety. Currently, three new direct oral anticoagulants are approved for stroke prevention in patients with non-valvular atrial fibrillation. For all three, there are data regarding its usefulness during the time of electrical or pharmacological cardioversion. Due to the ease of handling, their efficacy regarding stroke prevention, and their safety with respect to bleeding complications, the new direct oral anticoagulants are endorsed as the preferred therapy over vitamin K antagonists for stroke prevention in non-valvular atrial fibrillation including the clinical setting of elective cardioversion.
