rivaroxaban and Diabetes-Mellitus

This meta-analysis was conducted to compare the efficacy and safety of rivaroxaban with warfarin in patients with atrial fibrillation (AF) and diabetes mellitus.. PubMed, Embase, Cochrane Library, and Web of Science databases were systematically searched from the establishment of databases up to 15 October 2019. Studies on efficacy and safety outcomes of rivaroxaban and warfarin were included. Efficacy and safety outcomes, including stroke, ischemic stroke, stroke or systemic embolism, myocardial infarction, major adverse cardiac events, major bleeding, intracranial hemorrhage, and major gastrointestinal bleeding were collected for meta-analysis.. Compared with warfarin, rivaroxaban could significantly reduce stroke (risk ratio [RR] 0.77; 95% confidence interval [CI] 0.63-0.95; P = 0.01), ischemic stroke (RR 0.74; 95% CI 0.63-0.87; P = 0.0004), stroke or systemic embolism (RR 0.73; 95% CI 0.60-0.89; P = 0.002), myocardial infarction (RR 0.68; 95% CI 0.56-0.82; P < 0.0001), and major adverse cardiac events (RR 0.71; 95% CI 0.53-0.94; P = 0.02) in patients with AF and diabetes. Moreover, rivaroxaban was associated with a lower risk of major bleeding (RR 0.79; 95% CI 0.65-0.96; P = 0.02), intracranial hemorrhage (RR 0.52; 95% CI 0.39-0.69; P < 0.00001), and major gastrointestinal bleeding (RR 0.74; 95% CI 0.56-0.98; P = 0.04). Similar results were obtained in stratified meta-analysis of cohort studies.. Our study suggests a favorable risk-benefit profile of rivaroxaban, with superior efficacy and safety over warfarin in patients with AF and diabetes.

Atrial fibrillation is one of the most common concomitant diseases in patients with diabetes mellitus (DM). Meta-analyses of multiple studies have shown that the risk of AF is higher for diabetic patients with impaired glucose homeostasis than for patients without DM. Patients with AF and DM were younger, more frequently had arterial hypertension, chronic kidney disease, heart failure, and ischemic heart disease, and stroke and were characterized with a more severe course of AF. The article discusses possible mechanisms of the mutually aggravating effects of DM and AF, scales for evaluating the risk of bleeding (CHADS2, CHA2DS2‑VASc, HAS-BLED), and the role of anticoagulants. A meta-analysis of 16 randomized clinical studies, including 9 874 patients, has demonstrated the efficacy of oral anticoagulants in prevention of stroke with an overall decrease in the relative risk by 62 % compared to placebo (95% confidence interval, from 48 to 72 ). For prevention of complications in patients with AF and DM, current antithrombotic therapies can be used, specifically the oral factor Xa inhibitor, rivaroxaban, which is the best studied in patients with AF and DM and represents a possible alternative to warfarin in such patients.

Management of atrial fibrillation (AF) in patients with advanced chronic kidney disease (CKD) poses a complex conundrum because of higher risks for both thromboembolic and bleeding complications compared to the general population. This makes it particularly important for clinicians to carefully weigh the risks versus benefits of anticoagulation therapy to determine the individualized net clinical benefit for every patient. During the past few years, 4 non-vitamin K-dependent oral anticoagulant (NOAC) agents have supplemented warfarin in the therapeutic armamentarium for the prevention of systemic thromboembolism in nonvalvular AF. However, the use of NOACs in CKD specifically mandates a nuanced understanding due to their varying dependence on renal clearance, with resultant safety implications related to either underdosing (thromboembolism) or excessive drug exposure (bleeding). This pragmatic review highlights unique considerations pertaining to accurate estimation and temporal monitoring of kidney function in the context of NOAC use with specific clinical deliberations and variables when determining whether an NOAC is appropriate for a patient with CKD. The dependence of NOACs on renal clearance and several troubling safety signals in the published literature suggest that it is vital for nephrologists to be active members of a multidisciplinary team caring for these high-risk patients with CKD and AF.

COMMANDER-HF was a randomised trial comparing rivaroxaban 2.5 mg two times a day to placebo, in addition to antiplatelet therapy, in patients hospitalised for worsening heart failure with coronary artery disease and sinus rhythm. Patients with diabetes are at increased risk of cardiovascular events and therefore have more to gain.. In this post-hoc analysis, we evaluated the efficacy and safety of rivaroxaban in patients with (n=2052) and without diabetes (n=2970). The primary outcome was the composite of cardiovascular death, myocardial infarction (MI) or ischaemic stroke. HRs and 95% CIs with interaction analyses were used to describe event-rates and treatment effects. Patients with diabetes had a higher prevalence of cardiovascular comorbidities (eg, hypertension, obesity) and increased incidence of cardiovascular events. Adjusted HRs for events in people with versus without diabetes were 1.34 (95% CI 1.19 to 1.50) for the primary outcome, 1.21 (95% CI 0.84 to 1.75) for stroke, 1.51 (95% CI 1.14 to 1.99) for MI, 1.17 (95% CI 1.05 to 1.31) for heart failure hospitalisation and 1.06 (95% CI 0.56 to 2.01) for major bleeding. Rivaroxaban had no significant effect on event-rates in patients with and without diabetes (all interaction p values >0.05). Low-dose rivaroxaban was associated with an overall reduction in ischaemic stroke (HR 0.66; 95% CI 0.47 to 0.95), with no apparent subgroup interaction according to diabetes status (p-int=0.93).. In COMMANDER-HF a diagnosis of diabetes conferred higher rates of cardiovascular events that, with exception of ischaemic stroke, was not substantially reduced by rivaroxaban. Rivaroxaban was associated with reduced risk of ischaemic stroke for patients with and without diabetes.. NCT01877915; Post-results.

Low-dose rivaroxaban reduced major adverse cardiac and limb events among patients with stable atherosclerotic vascular disease (ASCVD) in the COMPASS trial. The objective of our study was to evaluate the eligibility and budgetary impact of the COMPASS trial in a real-world population.. The VA administrative and clinical databases were utilized to conduct a cross-sectional study to identify patients eligible for low-dose rivaroxaban receiving care at all 141 facilities between October 1, 2014 and September 30, 2015. Proportion of patients with stable ASCVD eligible for low-dose rivaroxaban and prevalence of multiple risk enrichment criteria among eligible patients. Pharmaceutical budgetary impact using VA pharmacy pricing. Chi-squared and Student's t tests were used to compare patients eligible versus ineligible patients.. From an initial cohort of 1,248,214 patients with ASCVD, 488,495 patients (39.1%) met trial eligibility criteria. Eligible patients were older (74.2 vs 64.5 years) with higher proportion of hypertension (84.1% vs 82.1%) and diabetes (46.2% vs 32.9) compared with ineligible patients (p < 0.001 for all comparisons). A median of 38.7% (IQR 4.6%) of total ASCVD patients per facility were rivaroxaban eligible. Estimated annual VA pharmacy budgetary impact would range from $0.47 billion to $1.88 billion for 25% to 100% treatment penetration. Annual facility level pharmaceutical budgetary impact would be a median of $12.3 million (IQR $8.0-$16.3 million) for treatment of all eligible patients. Among eligible patients, age greater than 65 years was the most common risk enrichment factor (86.9%). Prevalence of eligible patients with multiple enrichment factors varied from 34.2% (one factor) to 6.2% (four or more).. Over one third of patients with stable ASCVD may qualify for low-dose rivaroxaban within the VA. Additional studies are needed to understand eligibility in other populations and a formal cost-effectiveness analysis is warranted.

Patients with symptomatic lower extremity peripheral artery disease (LE-PAD) experience an increased risk of major vascular events. There is limited information on what clinical features of symptomatic LE-PAD prognosticate major vascular events and whether patients at high risk have a greater absolute benefit from low-dose rivaroxaban and aspirin.. To quantify the risk of major vascular events and investigate the response to treatment with low-dose rivaroxaban and aspirin among patients with symptomatic LE-PAD based on clinical presentation and comorbidities.. This is a subanalysis of a previously reported subgroup of patients with symptomatic LE-PAD who were enrolled in a large, double-blind, placebo-controlled randomized clinical trial (Cardiovascular Outcomes for People Using Anticoagulation Strategies [COMPASS]) in 602 centers in 33 countries from March 2013 to January 2020. Data analysis was completed from May 2016 to June 2020.. A combination of low-dose rivaroxaban and aspirin compared with aspirin alone.. Thirty-month incidence risk of myocardial infarction, stroke and cardiovascular death (MACE), major adverse limb events (MALE) including major vascular amputation, and bleeding.. The COMPASS trial enrolled 4129 patients with symptomatic LE-PAD (mean [SD] age, 66.8 [8.8] years; 2932 men [71.0%]). The 30-month Kaplan-Meier incidence risk of MACE or MALE, including major amputation, was 22.6% in those with prior amputation (this outcome was observed in 54 patients), 17.6% (n = 15) in those with Fontaine III or IV symptoms, and 11.8% (n = 142) in those with previous peripheral artery revascularization, classifying these features as high-risk limb presentations. The 30-month incidence risk of MACE or MALE, including major amputation, was 14.1% (n = 118) in those with kidney dysfunction, 13.5% (n = 67) in those with heart failure, 13.4% (n = 199) in those with diabetes, and 12.8% (n = 222) in those with polyvascular disease, classifying these features as high-risk comorbidities. Among patients with either high-risk limb presentations or high-risk comorbidities, treatment with rivaroxaban and aspirin compared with aspirin alone was associated with an estimated 4.2% (95% CI, 1.9%-6.2%) absolute risk reduction for MACE or MALE, including major amputation, at 30 months. Although the estimated absolute risk increase of major bleeding was higher with rivaroxaban and aspirin in combination than aspirin alone (2.0% [95% CI, 0.5%-3.9%]) for patients with either high-risk limb presentation or high-risk comorbidity, the estimated absolute risk increase of fatal or critical organ bleeding was low in this high-risk group (0.4% [95% CI, 0.2%-1.8%]), such that the net clinical benefit was estimated to be 3.2% (95% CI, 0.6%-5.3%).. Patients with LE-PAD with high-risk limb presentations or high-risk comorbidities had a high incidence of major vascular events. For these patients, treatment with rivaroxaban and aspirin in combination compared with aspirin alone led to a large absolute reduction in vascular risk.

The combination of 2.5 mg rivaroxaban twice daily and 100 mg aspirin once daily compared with 100 mg aspirin once daily reduces major adverse cardiovascular (CV) events in patients with chronic coronary artery disease (CAD) or peripheral artery disease (PAD).. The aim of this work was to report the effects of the combination on overall and cause-specific mortality.. The COMPASS trial enrolled 27,395 patients of whom 18,278 were randomized to the combination (n = 9,152) or aspirin alone (n = 9,126). Deaths were adjudicated by a committee blinded to treatment allocation. Previously identified high-risk baseline features were polyvascular disease, chronic kidney disease, mild or moderate heart failure, and diabetes.. During a median of 23 months of follow-up (maximum 47 months), 313 patients (3.4%) allocated to the combination and 378 patients (4.1%) allocated to aspirin alone died (hazard ratio [HR]: 0.82; 95% confidence interval [CI]: 0.71-0.96; P = 0.01). Compared with aspirin, the combination reduced CV death (160 [1.7%] vs 203 [2.2%]; HR: 0.78; 95% CI: 0.64-0.96; P = 0.02) but not non-CV death. There were fewer deaths following MI, stroke, and CV procedures, as well as fewer sudden cardiac, other, and unknown causes of CV deaths and coronary heart disease deaths. Patients with 0, 1, 2, and 3 or 4 high-risk features at baseline had 4.2, 4.8, 25.0, and 53.9 fewer deaths, respectively, per 1000 patients treated for 30 months.. The combination of rivaroxaban and aspirin compared with aspirin reduced overall and CV mortality with consistent reductions in cause specific CV mortality in patients with chronic CAD or PAD. The absolute mortality benefits are greater with increasing baseline risk. (Cardiovascular Outcomes for People Using Anticoagulant Strategies [COMPASS]; NCT01776424).

Vascular calcification is common in diabetic patients. Warfarin has been associated with renovascular calcification and worsening renal function; rivaroxaban may provide renopreservation by decreasing vascular inflammation. We compared the impact of rivaroxaban and warfarin on renal outcomes in diabetic patients with non-valvular atrial fibrillation (NVAF).. Using United States IBM MarketScan data from January 2011 to December 2017, we identified adults with both NVAF and diabetes, newly-initiated on rivaroxaban or warfarin with ≥12-month insurance coverage prior to anticoagulation initiation. Patients with Stage 5 chronic kidney disease (CKD) or undergoing haemodialysis at baseline were excluded. Differences in baseline covariates between cohorts were adjusted using inverse probability-of-treatment weighting (IPTW) based on propensity scores (absolute standardized differences <0.1 achieved for all after adjustment). Outcomes included incidence rates of emergency department/hospital admissions for acute kidney injury (AKI) and the composite of the development of Stage 5 CKD or need for haemodialysis. Patients were followed until an event, index anticoagulant discontinuation/switch, insurance disenrollment, or end-of-data availability. Hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated using Cox regression. We assessed 10 017 rivaroxaban (22.6% received a reduced dose) and 11 665 warfarin users. In comparison to warfarin, rivaroxaban was associated with lower risks of AKI (HR = 0.83, 95% CI = 0.74-0.92) and development of Stage 5 CKD or need for haemodialysis (HR = 0.82, 95% CI = 0.70-0.96). Sensitivity and subgroup analyses had similar effects as the base-case analysis.. Rivaroxaban appears to be associated with lower risks of undesirable renal outcomes vs. warfarin in diabetic NVAF patients.

Patients with established coronary artery disease or peripheral artery disease often have diabetes mellitus. These patients are at high risk of future vascular events.. In a prespecified analysis of the COMPASS trial (Cardiovascular Outcomes for People Using Anticoagulation Strategies), we compared the effects of rivaroxaban (2.5 mg twice daily) plus aspirin (100 mg daily) versus placebo plus aspirin in patients with diabetes mellitus versus without diabetes mellitus in preventing major vascular events. The primary efficacy end point was the composite of cardiovascular death, myocardial infarction, or stroke. Secondary end points included all-cause mortality and all major vascular events (cardiovascular death, myocardial infarction, stroke, or major adverse limb events, including amputation). The primary safety end point was a modification of the International Society on Thrombosis and Haemostasis criteria for major bleeding.. In stable atherosclerosis, the combination of aspirin plus rivaroxaban 2.5 mg twice daily provided a similar relative degree of benefit on coronary, cerebrovascular, and peripheral end points in patients with and without diabetes mellitus. Given their higher baseline risk, the absolute benefits appeared larger in those with diabetes mellitus, including a 3-fold greater reduction in all-cause mortality.

The prevalence of both atrial fibrillation (AF) and diabetes mellitus (DM) are rising, and these conditions often occur together. Also, DM is an independent risk factor for stroke in patients with AF. We aimed to examine the safety and efficacy of rivaroxaban vs warfarin in patients with nonvalvular AF and DM in a prespecified secondary analysis of the ROCKET AF trial.. We stratified the ROCKET AF population by DM status, assessed associations with risk of outcomes by DM status and randomized treatment using Cox proportional hazards models, and tested for interactions between randomized treatments. For efficacy, primary outcomes were stroke (ischemic or hemorrhagic) or non-central nervous system embolism. For safety, the primary outcome was major or nonmajor clinically relevant bleeding.. The 5,695 patients with DM (40%) in ROCKET AF were younger, were more obese, and had more persistent AF, but fewer had previous stroke (the CHADS2 score includes DM and stroke). The relative efficacy of rivaroxaban and warfarin for prevention of stroke and systemic embolism was similar in patients with (1.74 vs 2.14/100 patient-years, hazard ratio [HR] 0.82) and without (2.12 vs 2.32/100 patient-years, HR 0.92) DM (interaction P = .53). The safety of rivaroxaban vs warfarin regarding major bleeding (HRs 1.00 and 1.12 for patients with and without DM, respectively; interaction P = .43), major or nonmajor clinically relevant bleeding (HRs 0.98 and 1.09; interaction P = .17), and intracerebral hemorrhage (HRs 0.62 and 0.72; interaction P = .67) was independent of DM status. Adjusted exploratory analyses suggested 1.3-, 1.5-, and 1.9-fold higher 2-year rates of stroke, vascular mortality, and myocardial infarction in DM patients.. The relative efficacy and safety of rivaroxaban vs warfarin was similar in patients with and without DM, supporting use of rivaroxaban as an alternative to warfarin in diabetic patients with AF.

Heart failure (HF) is a critical complication in elderly patients with atrial fibrillation (AF) and diabetes mellitus (DM). Recent preclinical studies suggested that non-vitamin K antagonist oral anticoagulants (NOACs) can potentially suppress the progression of cardiac fibrosis and ischemic cardiomyopathy. Whether different oral anticoagulants influence the risk of HF in older adults with AF and DM is unknown. This study aimed to evaluate the risk of HF in elderly patients with AF and DM who were administered NOACs or warfarin.. A nationwide retrospective cohort study was conducted based on claims data from the entire Taiwanese population. Target trial emulation design was applied to strengthen causal inference using observational data. Patients aged  ≥ 65 years with AF and DM on NOAC or warfarin treatment between 2012 and 2019 were included and followed up until 2020. The primary outcome was newly diagnosed HF. Propensity score-based fine stratification weightings were used to balance patient characteristics between NOAC and warfarin groups. Hazard ratios (HRs) were estimated using Cox proportional hazard models.. The study included a total of 24,835 individuals (19,710 NOAC and 5,125 warfarin users). Patients taking NOACs had a significantly lower risk of HF than those taking warfarin (HR = 0.80, 95% CI 0.74-0.86, p < 0.001). Subgroup analyses for individual NOACs suggested that dabigatran (HR = 0.86, 95% CI 0.80-0.93, p < 0.001), rivaroxaban (HR = 0.80, 95% CI 0.74-0.86, p < 0.001), apixaban (HR = 0.78, 95% CI 0.68-0.90, p < 0.001), and edoxaban (HR = 0.72, 95% CI 0.60-0.86, p < 0.001) were associated with lower risks of HF than warfarin. The findings were consistent regardless of age and sex subgroups and were more prominent in those with high medication possession ratios. Several sensitivity analyses further supported the robustness of our findings.. This nationwide cohort study demonstrated that elderly patients with AF and DM taking NOACs had a lower risk of incident HF than those taking warfarin. Our findings suggested that NOACs may be the preferred oral anticoagulant treatment when considering the prevention of heart failure in this vulnerable population. Future research is warranted to elucidate causation and investigate the underlying mechanisms.

The healthcare resource utilization (HRU) and costs of oral anticoagulant-naïve patients with non-valvular atrial fibrillation (NVAF) and diabetes initiated on rivaroxaban or warfarin in the United States (US) has not been previously evaluated.. This retrospective study used data from the Optum's de-identified Clinformatics. After IPTW, 17,881 and 19,274 patients initiated on rivaroxaban and warfarin were included, respectively (mean age: 73 years; 40% female). During 12 months of follow-up, the rivaroxaban cohort had lower all-cause HRU PPY across all components, including lower rates of inpatient stays (RR: 0.84, 95% CI 0.81, 0.88), outpatient visits (RR: 0.67, 95% CI 0.66, 0.68), and 30 day hospital readmission (OR: 0.75, 95% CI 0.66, 0.83; all p < 0.001) compared to the warfarin cohort. Moreover, rivaroxaban was associated with medical cost savings PPY (mean cost difference: - $9306, 95% CI - $11,769, - $6607), which compensated for higher pharmacy costs relative to warfarin (mean cost difference: $5518, 95% CI $5193, $5839), resulting in significantly lower all-cause total healthcare costs for rivaroxaban versus warfarin (mean cost difference: - $3788, 95% CI - $6258, - $1035; all p < 0.001).. Among NVAF patients with diabetes in a real-world US setting, rivaroxaban was associated with lower healthcare costs compared to warfarin.

Diabetes represents a pro-thrombotic condition.. The primary objective was to evaluate the effects of Vitamin K Antagonist (VKA) compared to direct oral anticoagulants (DOACs) in diabetic and nondiabetic patients with non-valvular atrial fibrillation, newly diagnosed. The secondary objective was to evaluate the effects on the risk of bleeding.. We enrolled 300 patients with newly diagnosed atrial fibrillation. One hundred and sixteen patients were taking warfarin, 31 acenocumarol, 22 dabigatran, 80 rivaroxaban, 34 apixaban, and 17 edoxaban. We evaluated: anthropometric parameters, glycated hemoglobin (HbA. We did not record any differences among nondiabetic patients between VKA and DOACs. However, when we considered diabetic patients, we found a slight, but significant improvement of triglycerides and SD-LDL. As regards incidence of bleeding, minor bleeding was more frequent in VKA diabetic group compared to DOACs diabetic group; furthermore, the incidence of major bleeding was higher with VKA in nondiabetic and diabetic group, compared to patients with DOACs. Among DOACs, we recorded a higher incidence of bleeding (minor and major) with dabigatran compared to rivaroxaban, apixaban and edoxaban in nondiabetic and diabetic patients.. DOACs seem to be metabolically favourable in diabetic patients. Regarding incidence of bleeding, DOACs with the exception of dabigatran, seem better than VKA in diabetic patients.

To compare clinical outcomes of rivaroxaban and warfarin in patients with nonvalvular atrial fibrillation (NVAF) and concurrent obesity and diabetes.. Patients aged ≥18 years were identified from a healthcare claims database with the following criteria: newly initiating rivaroxaban or warfarin, ≥1 medical claim with a diagnosis of AF, obesity determined by validated machine learning algorithm, and ≥1 claim with a diagnosis of diabetes or for antidiabetic medication. Treatment cohorts were matched using propensity scores and were compared for stroke/systemic embolism (SE) and major bleeding using Cox proportional hazards models.. A total of 9999 matched pairs of NVAF patients with obesity and diabetes who initiated treatment with rivaroxaban or warfarin were included. The composite risk of stroke/SE was significantly lower in the rivaroxaban cohort compared with the warfarin cohort (HR 0.82; 95% CI 0.74-0.90). Risks of ischemic and hemorrhagic strokes were also significantly reduced with rivaroxaban versus warfarin, but not SE. Major bleeding risk was similar between treatment cohorts (HR 0.92; 95% CI 0.78-1.09).. In NVAF patients with comorbidities of obesity and diabetes, rivaroxaban was associated with lower risks of stroke/SE and similar risk of major bleeding versus warfarin.

To evaluate comparative effectiveness and safety of non-vitamin-K antagonist oral anticoagulants (NOACs) versus warfarin in Medicare beneficiaries with non-valvular atrial fibrillation (NVAF) and comorbid diabetes mellitus (DM).. A retrospective cohort study using 2014-2016 5% national Medicare data was undertaken. NVAF patients with DM aged ≥65 years having at least one prescription for NOACs or warfarin between July 2014 and December 2015 were included in the study. Propensity score matching was used to balance demographic and baseline clinical characteristics of patients in two treatment groups. Cardiovascular outcomes including stroke/systemic embolism (SE) and myocardial infarction (MI) were evaluated to measure effectiveness. Assessment of safety outcomes included intracranial hemorrhage (ICH), major gastrointestinal bleeding (MGB), bleeding from other sites (OB) and all-cause mortality. Stratified Cox proportional hazards models were used to estimate hazard ratios for the outcomes in the matched cohort.. The matched sample consisted of 4582 patients (2291 pairs). Compared to warfarin, NOACs had a significantly lower risk of stroke/SE (hazard ratio (HR): 0.373, 95% confidence interval (CI): 0.247-0.564,. Oral anticoagulation therapy with NOACs was found to be more effective than warfarin therapy among older adults with NVAF and comorbid DM.

Diabetes mellitus is a common comorbidity of atrial fibrillation (AF), which can complicate the management of AF. The pharmacology of oral anticoagulants (OACs) have been implicated in pathogenesis of diabetes, but the relationship between different OACs and risk of diabetes remains unexamined. This study aimed to evaluate the risk of diabetes with use of different OACs in AF patients.. Population-based retrospective cohort study using an electronic healthcare database managed by the Hong Kong Hospital Authority. Patients newly diagnosed with AF from 2014 through 2018 and prescribed OACs were included and followed till December 31, 2019. Inverse probability of treatment weighting based on the propensity score (PS) is used to address potential bias due to nonrandomized allocation of treatment. The risks ofdiabetes were compared between different new OAC users using propensity score-weighted cumulative incidence differences (CID).. There were 13,688 new users of OACs (warfarin: n = 3454; apixaban: n = 3335; dabigatran: n = 4210; rivaroxaban: n = 2689). The mean age was 75.0 (SD, 11.2), and 6,550 (47.9%) were women. After a median follow-up of 0.93 years (interquartile range, 0.21-1.92 years), 698 incident diabetes cases were observed. In Cox-regression analysis, dabigatran use was significantly associated with reduced risk of diabetes when compared with warfarin use [HR 0.69 (95% CI 0.56-0.86; P < 0.001)], with statistically insignificant associations observed for use of apixaban and rivaroxaban. The corresponding adjusted CIDs at 2 years after treatment with apixaban, dabigatran, and rivaroxaban users when compared with warfarin were - 2.06% (95% CI - 4.08 to 0.16%); - 3.06% (95% CI - 4.79 to - 1.15%); and - 1.8% (- 3.62 to 0.23%). In head-to-head comparisons between women DOAC users, dabigatran was also associated with a lower risk of diabetes when compared with apixaban and rivaroxaban.. Among adults with AF receiving OACs, the use of dabigatran had the lowest risk of diabetes when compared with warfarin use.

The safety and efficacy of nonvitamin K antagonist oral anticoagulants (NOACs) for the treatment of venous thromboembolism (VTE) have been established in randomized controlled trials, but limited data are available on their use in clinical practice across geographical regions.. In the international RE-COVERY DVT/PE observational study (enrollment January 2016 to May 2017), we sought to characterize the patient population and describe the prescribed anticoagulant. Patient characteristics and anticoagulants administered after objective diagnosis of VTE were recorded at the baseline visit and again at hospital discharge or at 14 days after the diagnosis, whichever was later.. A total of 6095 patients were included, 50.2% were male, and the mean age was 61.5 years. The most common comorbidities were hypertension (35%), diabetes mellitus (11%), cancer (11%), prior VTE(11%), and trauma/surgery (7%). Overall, 77% of patients received oral anticoagulants, with 54% on NOACs and 23% on vitamin K antagonists (VKAs); 20% received parenteral anticoagulation only. NOACs comprised about 60% of anticoagulant treatment in Europe and Asia but substantially less in Latin America (29%) and the Middle East (21%). For NOAC therapies, the distribution (as a percentage of the total cohort) was rivaroxaban 25.6%, dabigatran 15.5%, apixaban 11.3%, and edoxaban 1.7%. Treatment with NOACs was less frequent in patients who had cancer, chronic renal disease, heart failure, or stroke.. These findings enhance our understanding of baseline characteristics and the initial management of patients with VTE in routine practice.

The prevalence of diabetes is growing, and diabetes is an independent risk factor for both atrial fibrillation (AF) and stroke. However, the relative effectiveness and safety of different oral anticoagulants for diabetic patients with non-valvular AF remain unclear. We aimed to compare thromboembolic events, bleeding and mortality in diabetic AF patients treated with rivaroxaban, dabigatran and warfarin.. In diabetic AF patients, dabigatran and rivaroxaban showed a superior or non-inferior effectiveness and safety profile compared with warfarin. Dabigatran was associated with a significantly lower risk of mortality than rivaroxaban.

Digoxin is a widely used drug for ventricular rate control in patients with atrial fibrillation (AF), despite a scarcity of randomised trial data. We studied the use and outcomes of digoxin in patients in the Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF).. For this retrospective analysis, we included and classified patients from ROCKET AF on the basis of digoxin use at baseline and during the study. Patients in ROCKET AF were recruited from 45 countries and had AF and risk factors putting them at moderate-to-high risk of stroke, with or without heart failure. We used Cox proportional hazards regression models adjusted for baseline characteristics and drugs to investigate the association of digoxin with all-cause mortality, vascular death, and sudden death. ROCKET AF was registered with ClinicalTrials.gov, number NCT00403767.. In 14,171 randomly assigned patients, digoxin was used at baseline in 5239 (37%). Patients given digoxin were more likely to be female (42% vs 38%) and have a history of heart failure (73% vs 56%), diabetes (43% vs 38%), and persistent AF (88% vs 77%; p<0·0001 for each comparison). After adjustment, digoxin was associated with increased all-cause mortality (5·41 vs 4·30 events per 100 patients-years; hazard ratio 1·17; 95% CI 1·04-1·32; p=0·0093), vascular death (3·55 vs 2·69 per 100 patient-years; 1·19; 1·03-1·39, p=0·0201), and sudden death (1·68 vs 1·12 events per 100 patient-years; 1·36; 1·08-1·70, p=0·0076).. Digoxin treatment was associated with a significant increase in all-cause mortality, vascular death, and sudden death in patients with AF. This association was independent of other measured prognostic factors, and although residual confounding could account for these results, these data show the possibility of digoxin having these effects. A randomised trial of digoxin in treatment of AF patients with and without heart failure is needed.. Janssen Research & Development and Bayer HealthCare AG.

To investigate the clinical features and current therapy of atrial fibrillation (AF) of inpatients in Urumqi, China.. The clinical data of inpatients diagnosed with AF from January, 2008 to December, 2012, in 12 hospitals in Urumqi were retrospectively analyzed.. Totally 1 310 AF inpatients were enrolled in this study with the age of (64.8 ± 3.3) years old and a men to women ratio of 1.39. Most patients were in age groups of 61-70 years (26.5%) and 71-80 years (27.6%). More patients with paroxysmal AF were at cardiac function class I-II (75.2%), while more patients with persistent AF were at cardiac function class III-IV (31.0%) (both P values < 0.05). The most common co-morbidities of AF were hypertension (49.2%), coronary heart disease (38.5%), diabetes mellitus (20.1%). Compared with patients of chronic AF, the patients of paroxysmal AF had higher success rates in amiodarone conversation and sinus rhythm maintenance after ablation (44.8% vs 29.9%, 87.5% vs 68.9%, P values < 0.05). Among the 1 310 inpatients, 992 patients (75.7%) received antithrombotic therapy. There were statistically significant differences in CHA2DS2 score and incidence rate of cerebral infarction among patients receiving aspirin, warfarin or rivaroxaban/other anticoagulation drugs [2(1, 3) vs 3(2, 4) vs 3(2, 5) and 6.3% vs 23.8% vs 30.2%, both P values < 0.05].. Our results of AF inpatients' age, gender, related disease distribution, AF types, incidence of stoke, therapeutic and epidemiological features are in accordance with the domestic and abroad reports.
