Abstract
Objectives To analyze the clinical profile, adequacy of treatment with rivaroxaban and outcomes in octogenarians with atrial fibrillation (AF), taking rivaroxaban in clinical practice. Methods Observational and non-interventional study that included AF adults recruited from 79 Spanish centers, anticoagulated with rivaroxaban ≥ 6 months before being included. Data were analyzed according to age (≥ 80 vs. < 80 years) at baseline. Results Out of 1433 patients, 453 (31.6%) were octogenarians at baseline. Compared to younger patients, octogenarians had more comorbidities, higher CHA2DS2-VASc (4.5 ± 1.3 vs. 3.0 ± 1.4; P < 0.001) and HAS-BLED scores (2.0 ± 1.0 vs. 1.4 ± 1.0; P < 0.001). Overall, the dose of rivaroxaban was adequately prescribed in 83.4% of patients, but more frequently in the younger population (71.1% vs. 89.1%; P = 0.039). After a mean follow-up of 2.2 ± 0.6 years, annual rates of stroke + systemic embolism + transient ischemic attack, MACE, cardiovascular death and major bleeding were 1.03%, 1.24%, 1.03% and 1.75%, respectively, in octogenarian patients. Except for progressive heart failure death and major bleeding, rates of outcomes in octogenarians were similar compared to younger patients. In octogenarians, the concomitant use of antiplatelet agents and non-severe dementia were independently associated with the development of ischemic stroke, whereas previous coronary revascularization and heart failure with MACE, and higher HAS-BLED score with major bleeding. Conclusions In clinical practice, around one third of patients taking rivaroxaban are octogenarians. These patients have many comorbidities and a high thromboembolic risk. Despite that, rates of adverse events remain low. Rivaroxaban is adequately prescribed in the majority of octogenarians.

Abstract
Objective: To analyze the effectiveness and safety of rivaroxaban in patients with atrial fibrillation (AF). Methods: The clinical profile and outcomes of the EMIR study were indirectly compared with those of ROCKET-AF, eight other Spanish observational studies and XANTUS. Results: In EMIR, mean age was 74.2 years and CHA2DS2-VASc was 3.5. In the rivaroxaban arm of the ROCKET-AF trial, mean age was 73 years and CHADS2 was 3.5, whereas in the Spanish studies mean age ranged from 74.9 years to 78.4 years and CHA2DS2-VASc from 3.5 to 4.3. In EMIR, rates of stroke/systemic embolism, major adverse cardiovascular events, cardiovascular death and major bleeding were 0.57, 1.07, 0.63 and 1.04 events/100 patient-years, respectively. In ROCKET-AF, these numbers were 1.7, 3.91, 1.53 and 3.6 events/100 patient-years, respectively. In the Spanish studies, rates of stroke and major bleeding were 0-1.8 and 0.22-4.2 events/100 patient-years, respectively. In XANTUS, rates of stroke, major adverse cardiovascular events and major bleeding were 0.7, 1.8 and 2.1 events/100 patient-years, respectively. Conclusion: Despite the fact that rivaroxaban is prescribed for elderly patients with a high thromboembolic risk, rates of outcomes remain low.

Abstract
Aim: To analyze the frequency and variables related to inappropriate rivaroxaban dosage in clinical practice and its impact on outcomes after 2 years. Materials & methods: Postauthorization, observational, multicenter study, in which atrial fibrillation patients, treated with rivaroxaban ≥6 months were included. Results: A total of 1421 patients (74.2 ± 9.7 years, CHA2DS2-VASc 3.5 ± 1.6) were included. Overall, 22.9% received rivaroxaban 15 mg. The proper dose of rivaroxaban was taken by 83.3% (9.7% underdosed, 7.0% overdosed). Older age and renal insufficiency were associated with inadequate rivaroxaban dosage. There was a trend toward higher all-cause mortality among underdosed patients (adjusted hazard ratio 1.39; 95% CI 0.75-2.58), and more bleedings in overdosed patients (2.29 vs 0.80 events/100 patient-years; p = 0.14). Conclusion: In clinical practice, rivaroxaban is properly dosed in most patients.

Clinical profile and management of rivaroxaban in patients with atrial fibrillation in routine practice in Spain: data from six nationwide studies. Drugs Context 2019; 8:212606. [PMID: 31692949 PMCID: PMC6822684 DOI: 10.7573/dic.212606] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2019] [Revised: 09/03/2019] [Accepted: 09/09/2019] [Indexed: 11/21/2022] Open
Abstract
AIMS To analyze the clinical profile and management of patients with nonvalvular atrial fibrillation taking rivaroxaban in routine practice in Spain. METHODS Clinical data from the observational studies HEROIC (cardiology and hematology; n=1,727), EMIR (cardiology; n=1,493), BRONCE-AP (primary care; n=133), SILVER-AP (primary care; n=457), ALADIN (internal medicine and neurology; n=249), and ESPARTA (internal medicine; n=110) of patients taking rivaroxaban were analyzed. The clinical profile was compared with those of the XANTUS and ROCKET-AF studies. RESULTS Overall, mean age was 74.9±9.4 years, CHA2DS2-VASc score was 3.7±1.5, and 43.2% had a HAS-BLED score ≥3. Patients included in the HEROIC and EMIR studies were older and more frequently had a creatinine clearance <50 mL/min and a higher thromboembolic risk than those in the XANTUS study, and patients included in the ALADIN study were older and had more prior cerebrovascular disease, but a lower thromboembolic risk than those in the ROCKET-AF trial. In those studies with available data, medication adherence and satisfaction with rivaroxaban were high. CONCLUSION Bearing in mind differences according to the clinical setting of each study, atrial fibrillation patients taking rivaroxaban in Spain were elderly and had a high thromboembolic risk. Medication adherence and satisfaction with rivaroxaban were high.
