Objective: To ascertain the clinical profile, management and rates of thromboembolic and bleeding complications in a contemporary cohort of patients with nonvalvular atrial fibrillation (NVAF) on rivaroxaban treatment, with a particular focus on some subgroups of patients.

Methods: Retrospective study that included all NVAF patients who started treatment with rivaroxaban for the prevention of stroke or systemic embolism between December 2012 and December 2015. Rates of outcomes (stroke, nonfatal myocardial infarction, major bleeding, intracranial bleeding and death) during follow-up were calculated.

Results: A total of 732 patients (mean age 76.4?±?9.2?years; 54.5% women) were included. Comorbidities were common (hypertension 87.5%; diabetes 26.5%; renal insufficiency 24.6%; prior stroke/transient ischemic attack 16.8%). Mean CHA2DS2-VASc was 3.9?±?1.5 and HAS-BLED 2.3?±?0.9; 61.9% of patients were rivaroxaban naïve users. After a mean treatment period of 22.7?±?7.4?months, rates of stroke, nonfatal myocardial infarction, major bleeding, intracranial bleeding and death were 1.8, 1.0, 3.2, 0.4 and 5.5 events per 100 patient-years, respectively. Rates of stroke and death were higher in patients >75?years (vs. ≤75?years) and in patients with prior stroke/transient ischemic attack or renal insufficiency. Rates of major bleeding were higher among patients >75?years and in patients with prior stroke/transient ischemic attack.

Conclusions: In this contemporary Spanish cohort of NVAF patients on rivaroxaban, patients had many comorbidities, a high thromboembolic risk and a moderate bleeding risk. Overall, rates of stroke and bleeding complications were low and similar to other previous studies. These data suggest that rivaroxaban is effective and safe in routine practice.  相似文献

Objectives: Renal dysfunction is associated with increased risk of cardiovascular disease and is an independent predictor of stroke and systemic embolism. Nonvalvular atrial fibrillation (NVAF) patients with renal dysfunction may face a particularly high risk of thromboembolism and bleeding. The current retrospective cohort study was designed to assess the impact of renal function on ischemic stroke and major bleeding rates in NVAF patients in the real-world setting (outside a clinical trial).

Methods: Medical claims and Electronic Health Records were retrieved retrospectively from Optum’s Integrated Claims–Clinical de-identified dataset from May 2011 to August 2014. Patients with NVAF treated with warfarin (2468) or rivaroxaban (1290) were selected. Each treatment cohort was stratified by baseline estimated creatinine clearance (eCrCl) levels. Confounding adjustments were made using inverse probability of treatment weights (IPTWs). Incidence rates and hazard ratios of ischemic stroke and major bleeding events were calculated for both cohorts.

Results: Overall, patients treated with rivaroxaban had an ischemic stroke incidence rate of 1.9 per 100 person-years (PY) while patients treated with warfarin had a rate of 4.2 per 100 PY (HR?=?0.41 [0.21–0.80], p?=?.009). Rivaroxaban patients with an eCrCl below 50?mL/min (N?=?229) had an ischemic stroke rate of 0.8 per 100 PY, while the rate for the warfarin cohort (N?=?647) was 6.0 per 100 PY (HR?=?0.09 [0.01–0.72], p?=?.02). For the other renal function levels (i.e. eCrCl 50–80 and ≥80?mL/min) HRs indicated no statistically significant differences in ischemic stroke risks. Bleeding events did not differ significantly between cohorts stratified by renal function.

Conclusions: Ischemic stroke rates were significantly lower in the overall NVAF population for rivaroxaban vs. warfarin users, including patients with eCrCl below 50?mL/min. For all renal function groups, major bleeding risks were not statistically different between treatment groups.  相似文献

Nonvalvular atrial fibrillation (NVAF) is frequently seen in elderly people and has become a main cause of cardioembolic stroke. The efficacy of anticoagulation for primary prevention of stroke or transient ischaemic attacks (TIAs) in patients with NVAF has been established by prospective, randomised and controlled trials. Warfarin decreased the frequency of all strokes by 68% and the rate of the combined outcome of stroke, systemic embolism or death by 48%. Anticoagulation with warfarin using international normalised ratios (INRs) ranging from 2.0 to 3.0 is recommended for patients with NVAF, who have any of the risk factors identified by the Atrial Fibrillation Investigators (AFI) [previous stroke or TIA, history of hypertension, diabetes mellitus, advanced age (> or = 65 years old), congestive heart failure and coronary artery disease], the American College of Chest Physicians (ACCP) [increased age (> 75 years old), prior stroke, hypertension and heart failure], or the Stroke Prevention in Atrial Fibrillation (SPAF) investigators [women > 75 years old, prior stroke, systolic blood pressure > 160mm Hg, recent heart failure, and fractional shortening < 25% on echocardiography]. For the secondary prevention of stroke, the efficacy of adjusted-dose warfarin therapy has been demonstrated by 2 major randomised trials. SPAF III (INR 2.0 to 3.0) demonstrated a lower incidence of ischaemic stroke or systemic embolism (3.4 %/year) compared with low fixed-dose warfarin plus aspirin (acetylsalicylic acid) [11.9%]. The European Atrial Fibrillation Trial [EAFT] (INR 2.5 to 4.0) showed a lower incidence of all stroke (4.0 %/year) with adjusted-dose warfarin compared with placebo (12.0 %/year). The incidence of major bleeding in the adjusted-dose warfarin group in SPAF III and EAFT was 2.4 and 2.8 %/year, respectively. EAFT incidence rates for the occurrence of a first ischaemic or haemorrhagic complication analysed by INR range indicated that the rate was lowest at INRs of 2.0 to 2.9, and higher with INRs of 3.0 to 3.9. Therefore, the optimal intensity of anticoagulation for prevention of recurrent stroke seems to be an INR of between 2.0 and 3.0, as for primary prevention. Retrospective and prospective studies from Japan reported that in the elderly, haemorrhagic complications occur frequently with INRs above 2.6 and major ischaemic events cannot be prevented at INRs below 1.6. Therefore, an INR target between 1.6 and 2.6 may be an alternative for secondary prevention of stroke in elderly patients with NVAF who have a potential risk of bleeding, to avoid both major ischaemic and haemorrhagic events. Antiplatelets may be administered in patients who are unable to manage taking warfarin properly or who have a high risk of falling and subsequently sustaining a head injury, although the efficacy of antiplatelets for secondary prevention of stroke in NVAF has not yet been established.  相似文献

Objective: Dabigatran and rivaroxaban have been approved by the US FDA to reduce the risk of stroke and systemic embolism in non-valvular atrial fibrillation (NVAF) patients. Newly published real-world evidence based on the US population found that elderly Medicare patients with NVAF treated with rivaroxaban experienced statistically significant increases in intracranial hemorrhage (ICH) and major extracranial bleeding, and statistically nonsignificant decreases in thromboembolic stroke and acute myocardial infarction (AMI) compared with dabigatran. This study assessed the cost-effectiveness of dabigatran vs. rivaroxaban for the treatment of US Medicare NVAF patients.

Methods: A previously published Markov model was adapted to compare dabigatran and rivaroxaban. The model considered thromboembolic stroke, bleeding events, and AMI based on the published real-world event risks. Model outputs included clinical event rates, costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs).

Results: Dabigatran patients experienced fewer ICH and major extracranial bleeding events than rivaroxaban patients, but more stroke and AMI events. Dabigatran was found to yield lower costs and higher QALYs than rivaroxaban, with incremental costs of ?$3534 and incremental QALYs of 0.004. Results remained consistent in sensitivity analyses, with a positive net monetary benefit (willingness-to-pay thresholds of $50,000 and $100,000 per QALY) for dabigatran over rivaroxaban for all model inputs tested.

Conclusions: In this study using US Medicare real-world data, dabigatran was found to dominate rivaroxaban. The analyses were limited by the short follow-up period of the real-world data and results may not be generalizable to other patient populations.  相似文献

Objective:

Clinical trials have demonstrated that direct oral anticoagulants (DOACs) are efficacious in reducing stroke risk among patients with nonvalvular atrial fibrillation (NVAF) with differences in the reduction of bleeding risks vs. warfarin. The objective of this study was to assess bleeding-related hospital readmissions among hospitalized NVAF patients treated with dabigatran, rivaroxaban, and apixaban in the US.

Research design and methods:

Patients (≥18 years) with a discharge diagnosis of NVAF who received apixaban, dabigatran, or rivaroxaban during hospitalization were identified from the Premier Hospital database (1 January 2012–31 March 2014) and the Cerner Health Facts hospital database (1 January 2012–31 August 2014). Patients identified from each database were analyzed separately and grouped into three cohorts depending on which DOAC was received. Patient characteristics, hospital resource use and costs, and frequency of readmissions within 1 month were evaluated.

Results:

Among study populations identified from the Premier database (N?=?74,730) and the Cerner database (N?=?14,201), patients who received apixaban were older, had greater comorbidity, and had higher stroke and bleeding risks. After controlling for patient characteristics, including comorbidity and stroke and bleeding risks, compared with patients who received apixaban during their index hospitalizations, the odds of bleeding-related hospital readmissions were significantly greater by 1.4-fold (p?<?0.01) for patients who received rivaroxaban and 1.2-fold (p?=?0.16) numerically greater for patients who received dabigatran among patients identified from the Premier Hospital database. Among patients in the Cerner Health Facts hospital database, bleeding-related hospital readmissions were significantly greater by 1.6-fold (p?=?0.04) for patients who received rivaroxaban and 1.3-fold (p?=?0.30) numerically greater for patients who received dabigatran compared to patients who received apixaban.

Limitations:

No causal relationship between treatment and outcomes can be concluded.

Conclusions:

NVAF patients using different DOACs had different characteristics, including stroke and bleeding risks. Use of rivaroxaban, compared to apixaban was associated with significantly greater risk of bleeding-related readmissions across two database claims analyses.  相似文献
