Background And Objectives: The prevalence of atrial fibrillation (AF) and ischaemic heart disease (IHC) increases with age. They coexist in up to 20% of octogenarian patients, a situation that poses a therapeutic challenge. Trials that have addressed this scenario, which included a low percentage of octogenarians, showed that double therapy (single antiplatelet + anticoagulation) compared to triple therapy (double antiplatelet + anticoagulation) was associated with less bleeding events, especially with direct oral anticoagulants.

The new coronavirus SARS-CoV-2, which gives rise to the highly contagious COVID-19 disease, has caused a pandemic that is overwhelming health care systems worldwide. Affected patients have been reported to have a heightened inflammatory state that increases their thrombotic risk. However, there is very scarce information on the management of thrombotic risk, coagulation disorders, and anticoagulant therapy.

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.

Introduction: There is compelling evidence supporting the association between high on-treatment platelet reactivity (HPR) and low on-treatment platelet reactivity (LPR) to clopidogrel with atherothrombotic and bleeding events, respectively. However, it is uncertain if current cutoff values should be used in prasugrel- or ticagrelor-treated subjects. The objective of this analysis was to evaluate the pharmacodynamic (PD) efficacy of P2Y antagonists in a contemporary real-world population.

During the last few years, the number of patients receiving anticoagulant and antiplatelet therapy has increased worldwide. Since this is a chronic treatment, patients receiving it can be expected to need some kind of surgery or intervention during their lifetime that may require treatment discontinuation. The decision to withdraw antithrombotic therapy depends on the patient's thrombotic risk versus hemorrhagic risk.

Aims: To describe the prevalence and associated factors of inappropriate doses of direct oral anticoagulants (DOAC) in a national registry of patients of real clinical practice.

Methods And Results: Five hundred and thirty outpatients with atrial fibrillation treated with DOAC were included in a prospective, national, multicentre study. The appropriateness of the doses of DOAC was defined according to the recommendations of the European Heart Rhythm Association.

Background: Several bleeding risk scores have been validated in patients with atrial fibrillation (AF). The ORBIT score has been recently proposed as a simple score with the best ability to predict major bleeding. The present study aimed to test the hypothesis that the ORBIT score was superior to the HAS-BLED score for predicting major bleeding and death in "real world" anticoagulated AF patients.

Article Synopsis
  • Vitamin K antagonists (VKAs) are commonly used in treating nonvalvular atrial fibrillation (AF), especially in octogenarians, who have been found to possess a higher risk profile for stroke and bleeding.
  • A study involving 1,637 patients showed that those over 80 years old had significantly poorer renal function and higher risk scores for stroke and bleeding compared to younger patients.
  • Despite these risks, the quality of anticoagulation with VKAs, measured by international normalized ratio values, was found to be comparable between octogenarians and younger patients.

Introduction: Economic evaluations are becoming increasingly important due to limitations in economic resources, the expense of many new treatments, the need to allocate health spending as effectively as possible, and the need to inform decision makers. Based on the data from the apixaban studies (ARISTOTLE and AVERROES), several economic evaluations have been performed in various countries to demonstrate the efficacy of apixaban versus warfarin and aspirin or other new oral anticoagulants (NOACs) for preventing stroke in patients with non-valvular atrial fibrillation (NVAF).The aim of this study was to perform a systematic literature review of published economic evaluations with apixaban in the indication of stroke prevention in patients with NVAF.

Introduction: Atrial fibrillation (AF) is associated with an increased risk of thromboembolic events. Many patients with AF receive chronic anticoagulation, either with vitamin K antagonists (VKAs) or with non-VKA oral anticoagulants (NOACs). We sought to analyze variables associated with prescription of NOAC.

Background: Vitamin K antagonists (VKA) have a narrow therapeutic range, and literature analysis reveals poor quality of anticoagulation control. We sought to assess the prevalence of poor anticoagulant control in patients under VKA treatment in the prevention of stroke for atrial fibrillation (AF).

Hypothesis: Control of anticoagulation with VKA is inadequate in a high percentage of patients with AF.

Objectives: To assess the clinical characteristics and inter-hospital variability in the treatment and prognosis of patients with non-ST-segment elevation acute coronary syndromes.

Patients And Method: Data from the PEPA study, a prospective registry that enrolled 4,115 patients in 18 Spanish hospitals, were analyzed.

Results: The mean age of the patients enrolled was 65 years, 33% were women, and 26% had diabetes.
