Abstract 15467: Impact of Thrombocytopenia on Clinical Outcomes in Atrial Fibrillation Patients With Anemia: The Fushimi Af Registry

Introduction: Anemia has been reported to be associated with poor prognosis in patients with atrial fibrillation (AF). Concomitant thrombocytopenia (TP) may or may not affect the prescription of antithrombotic drugs and clinical outcomes in these patients. Methods: The Fushimi AF Registry is a community-based prospective survey of AF patients in Fushimi-ku, Kyoto. We defined TP as platelet counts less than 150,000/μL and anemia as hemoglobin less than 11 g/dL. Among 666 patients with anemia, we compared the clinical backgrounds and outcomes of those with TP (n=183) and those without (n=483). Results: Compared with patients without TP, patients with TP were more likely to have chronic kidney disease (75.4% vs. 61.8%, p=0.001), and less likely to have hypertension (58.5% vs. 67.0%, p=0.0393), and less likely to have dyslipidemia (27.3% vs. 38.3%, p=0.0079). Age, sex, body weight, CHADS 2 score, CHA 2 DS 2 -VASc score, HAS-BLED score, and previous major bleeding were comparable between the groups. Furthermore, prescription of anti-thrombotic drugs was comparable (Figure A). On Kaplan-Meier analysis, the incidence of all-cause death was higher in TP group (hazard ratio [HR] 1.52; 95% confidence interval [CI] 1.20-1.91, p<0.05) (Figure B-1). There was no significant difference in other adverse events between patients with and without TP (major bleeding: HR 1.11; 95% CI 0.41-3.31, p=0.8, hospitalization for heart failure: HR 1.11; 95% CI 0.74-1.61, p= 0.61 and stroke or systemic embolism: HR 0.91; 95% CI 0.43-1.78, p=0.80) (Figure B-2, 3, 4). Multivariate Cox proportional hazards regression analysis adjusting for potential confounders revealed that TP was an independent determinant of all-cause death (adjusted HR: 1.41, 95% CI; 1.11-1.78, p=0.006). Conclusions: Concomitant TP in AF patients with anemia did not affect the prescription of antithrombotic drugs, and was independently associated with all-cause death in the Fushimi AF Registry.

Warfarin Treatment

SummaryThe ARISTOTLE trial showed a risk reduction of stroke/systemic embolism (SE) and major bleeding in non-valvular atrial fibrillation (NVAF) patients treated with apixaban compared to warfarin. This retrospective study used four large US claims databases (MarketScan, PharMetrics, Optum, and Humana) of NVAF patients newly initiating apixaban or warfarin from January 1, 2013 to September 30, 2015. After 1:1 warfarin-apixaban propensity score matching (PSM) within each database, the resulting patient records were pooled. Kaplan-Meier curves and Cox proportional hazards models were used to estimate the cumulative incidence and hazard ratios (HRs) of stroke/SE and major bleeding (identified using the first listed diagnosis of inpatient claims) within one year of therapy initiation. The study included a total of 76,940 (38,470 warfarin and 38,470 apixaban) patients. Among the 38,470 matched pairs, 14,563 were from MarketScan, 7,683 were from PharMetrics, 7,894 were from Optum, and 8,330 were from Humana. Baseline characteristics were balanced between the two cohorts with a mean (standard deviation [SD]) age of 71 (12) years and a mean (SD) CHA2DS2-VASc score of 3.2 (1.7). Apixaban initiators had a significantly lower risk of stroke/SE (HR: 0.67, 95 % CI: 0.59–0.76) and major bleeding (HR: 0.60, 95 % CI: 0.54–0.65) than warfarin initiators. Different types of stroke/SE and major bleeding – including ischaemic stroke, haemorrhagic stroke, SE, intracranial haemorrhage, gastrointestinal bleeding, and other major bleeding – were all significantly lower for apixaban compared to warfarin treatment. Subgroup analyses (apixaban dosage, age strata, CHA2DS2-VASc or HAS-BLED score strata, or dataset source) all show consistently lower risks of stroke/SE and major bleeding associated with apixaban as compared to warfarin treatment. This is the largest “real-world” study on apixaban effectiveness and safety to date, showing that apixaban initiation was associated with significant risk reductions in stroke/SE and major bleeding compared to warfarin initiation after PSM. These benefits were consistent across various high-risk subgroups and both the standard-and low-dose apixaban dose regimens.Note: The review process for this manuscript was fully handled by Christian Weber, Editor in Chief.Supplementary Material to this article is available online at www.thrombosis-online.com.

SummaryIn addition to warfarin, there are four non-vitamin K antagonist oral anticoagulants (NOACs) available for stroke prevention in non valvular atrial fibrillation (NVAF). There are limited data on the comparative risks of major bleeding among newly anticoagulated NVAF patients who initiate warfarin, apixaban, dabigatran, or rivaroxaban, when used in ‘real world’ clinical practice. The study used the Truven MarketScan® Commercial & Medicare supplemental US claims database. NVAF patients aged ≥18 years newly prescribed an oral anticoagulant 01JAN2013–31DEC2014, with a ≥1-year baseline period, were included (study period: 01JAN2012–31DEC2014). Major bleeding was defined as bleeding requiring hospitalisation. Propensity score matching (PSM) was used to balance age, sex, region, baseline comorbidities, and comedications. Cox proportional hazards models were used to estimate the PSM hazard ratio (HR) of major bleeding. Among 45,361 newly anticoagulated NVAF patients, 15,461 (34.1 %) initiated warfarin, 7,438 (16.4 %) initiated apixaban, 17,801 (39.2 %) initiated rivaroxaban, and 4,661 (10.3 %) initiated dabigatran. Compared to matched warfarin initiators, apixaban (HR: 0.53; 95 % CI: 0.39–0.71) and dabigatran (HR: 0.69; 95 % CI: 0.50–0.96) initiators had a significantly lower risk of major bleeding. Patients initiating rivaroxaban (HR: 0.98; 95 % CI: 0.83–1.17) had a non-significant difference in major bleeding risk compared to matched warfarin patients. When comparisons were made between NOACs, matched rivaroxaban patients had a significantly higher risk of major bleeding (HR: 1.82; 95 % CI: 1.36–2.43) compared to apixaban patients. The differences for apixaban-dabigatran and dabigatran-rivaroxaban matched cohorts were not statistically significant. Among newly anticoagulated NVAF patients in the real-world setting, apixaban and dabigatran initiation was associated with significantly lower risk of major bleeding compared to warfarin initiation. When compared to apixaban, rivaroxaban initiation was associated with significantly higher risk of major bleeding.Note: The review process for this paper was fully handled by Christian Weber, Editor in Chief.Supplementary Material to this article is available online at www.thrombosis-online.com.

All Cause Mortality

Background. There are no proven effective treatments that can reduce the mortality in heart failure with preserved ejection fraction (HFpEF), probably due to its heterogeneous nature which will weaken the effect of therapy in clinical studies. We evaluated the effect of beta-blocker treatment in HFpEF patients associated with atrial fibrillation (AF), which is a homogeneous syndrome and has seldom been discussed. Methods. This retrospective cohort study screened 955 patients diagnosed with AF and HFpEF. Patients with a range of underlying heart diseases or severe comorbidities were excluded; 191 patients were included and classified as with or without beta-blocker treatment at baseline. The primary outcome was all-cause mortality and rehospitalization due to heart failure. Kaplan-Meier curves and multivariable Cox proportional-hazards models were used to evaluate the differences in outcomes. Results. The mean follow-up was 49 months. After adjustment for multiple clinical risk factors and biomarkers for prognosis in heart failure, patients with beta-blocker treatment were associated with significantly lower all-cause mortality (hazard ratio (HR) = 0.405, 95% confidence interval (CI) = 0.233–0.701, p=0.001) compared with those without beta-blocker treatment. However, the risk of rehospitalization due to heart failure was increased in the beta-blocker treatment group (HR = 1.740, 95% CI = 1.085–2.789, p=0.022). There was no significant difference in all-cause rehospitalization between the two groups (HR = 1.137, 95% CI = 0.803–1.610, p=0.470). Conclusions. In HFpEF patients associated with AF, beta-blocker treatment is associated with significantly lower all-cause mortality, but it increased the risk of rehospitalization due to heart failure.

Gi Bleed

Background: Gastrointestinal (GI) bleeding is the most common type of major bleeding associated with oral anticoagulant (OAC) treatment. Patients with major bleeding are at an increased risk of a stroke if an OAC is not reinitiated. Methods: Non-valvular atrial fibrillation (NVAF) patients initiating OACs were identified from the Centers for Medicare and Medicaid Services ( CMS) Medicare data and four US commercial claims databases. Patients who had a major GI bleeding event (hospitalization with primary diagnosis of GI bleeding) while on an OAC were selected. A control cohort of patients without a major GI bleed during OAC treatment was matched to major GI bleeding patients using propensity scores. Stroke/systemic embolism (SE), major bleeding, and mortality (in the CMS population) were examined using Cox proportional hazards models with robust sandwich estimates. Results: A total of 15,888 patients with major GI bleeding and 833,052 patients without major GI bleeding were included in the study. Within 90 days of the major GI bleed, 58% of patients discontinued the initial OAC treatment. Patients with a major GI bleed had a higher risk of stroke/SE [hazard ratio (HR): 1.57, 95% confidence interval (CI): 1.42–1.74], major bleeding (HR: 2.79, 95% CI: 2.64–2.95), and all-cause mortality (HR: 1.29, 95% CI: 1.23–1.36) than patients without a major GI bleed. Conclusion: Patients with a major GI bleed on OAC had a high rate of OAC discontinuation and significantly higher risk of stroke/SE, major bleeding, and mortality after hospital discharge than those without. Effective management strategies are needed for patients with risk factors for major GI bleeding.

The Impact

Data supporting the use of etoposide-based therapy in hemophagocytic lymphohistiocytosis (HLH) arise largely from pediatric studies. There is a lack of comparable data among adult patients with secondary HLH. We conducted a retrospective study to assess the impact of etoposide-based therapy on outcomes in adult secondary HLH. The primary outcome was overall survival. The log-rank test was used to compare Kaplan-Meier distributions of time-to-event outcomes. Multivariable Cox proportional hazards modeling was used to estimate adjusted hazard ratios (HRs) with 95% confidence intervals (CIs). Ninety adults with secondary HLH seen between January 1, 2009, and January 6, 2020, were included. Forty-two patients (47%) received etoposide-based therapy, while 48 (53%) received treatment only for their inciting proinflammatory condition. Thirty-three patients in the etoposide group (72%) and 32 in the no-etoposide group (67%) died during follow-up. Median survival in the etoposide and no-etoposide groups was 1.04 and 1.39 months, respectively. There was no significant difference in survival between the etoposide and no-etoposide groups (log-rank <i>p</i> = 0.4146). On multivariable analysis, there was no association between treatment with etoposide and survival (HR for death with etoposide = 1.067, 95% CI: 0.633–1.799, <i>p</i> = 0.8084). Use of etoposide-based therapy was not associated with improvement in outcomes in this large cohort of adult secondary HLH patients.

Abstract Background Academic medical centers invest considerably in faculty development efforts to support the career success and promotion of their faculty, and to minimize faculty attrition. This study evaluated the impact of a faculty development program called the Leadership in Academic Medicine Program (LAMP) on participants’ (1) self-ratings of efficacy, (2) promotion in academic rank, and (3) institutional retention. Method Participants from the 2013–2020 LAMP cohorts were surveyed pre and post program to assess their level of agreement with statements that spanned domains of self-awareness, self-efficacy, satisfaction with work and work environment. Pre and post responses were compared using McNemar’s tests. Changes in scores across gender were compared using Wilcoxon Rank Sum/Mann-Whitney tests. LAMP participants were matched to nonparticipant controls by gender, rank, department, and time of hire to compare promotions in academic rank and departures from the organization. Kaplan Meier curves and Cox proportional hazards models were used to examine differences. Results There were significant improvements in almost all self-ratings on program surveys (p < 0.05). Greatest improvements were seen in “understand the promotions process” (36% vs. 94%), “comfortable negotiating” (35% vs. 74%), and “time management” (55% vs. 92%). There were no statistically significant differences in improvements by gender, however women faculty rated themselves lower on all pre-program items compared to men. There was significant difference found in time-to-next promotion (p = 0.003) between LAMP participants and controls. Kaplan-Meier analysis demonstrated that LAMP faculty achieved next promotion more often and faster than controls. Cox-proportional-hazards analyses found that LAMP faculty were 61% more likely to be promoted than controls (hazard ratio [HR] 1.61, 95% confidence interval [CI] 1.16–2.23, p-value = 0.004). There was significant difference found in time-to-departure (p < 0.0001) with LAMP faculty retained more often and for longer periods. LAMP faculty were 77% less likely to leave compared to controls (HR 0.23, 95% CI 0.16–0.34, p < 0.0001). Conclusions LAMP is an effective faculty development program as measured subjectively by participant self-ratings and objectively through comparative improvements in academic promotions and institutional retention.

Background: History of bleeding is important in decisions for anticoagulation. We analyzed outcomes in relation to history of bleeding and randomized treatments in patients with atrial fibrillation (AF) in the ARISTOTLE trial. Methods: The on-treatment safety population included 18,140 patients receiving ≥1 dose of study drug, apixaban 5 mg bd (2.5 mg bd if 2 of the following: age >80 yrs; body weight <60 kg; or creatinine >133 μmol/L) or warfarin aiming for INR 2.0-3.0 (median TTR 66%), for a median of 1.8 yrs. Adjudicated outcomes in relation to randomization and history of bleeding were analyzed using a Cox proportional hazards model. Efficacy endpoints were analyzed in the intention-to-treat population. Results: A history of bleeding was reported in 3033 patients (16.7%), who more often were male (68% vs 64%, p <0.0005); with a history of prior stroke/TIA/systemic embolism (23% vs 19%, p <0.0001); diabetes (27% vs 24%, p=0.0010); higher CHADS2 score (CHADS2 >3: 35% vs 29%), age (mean [SD] 71 [9] vs 69 [10], p <0001) and body weight (86 [21] vs 84 [21], p <0.0001); lower creatinine clearance (77 [33] vs 80 [33], p=0.0007) and mean systolic blood pressure (131 [17] vs 132 [16], p=0.0027). Calcium channel blockers, statins, non-steroidal anti-inflammatory drugs and proton pump inhibitors were used more often in patients with vs without a history of bleeding. Major bleeding was the only outcome event occurring more frequently in patients with vs without a history of bleeding, HR 1.7 (95% CI 1.4-2.3) with apixaban and 1.5 (1.2-1.0) with warfarin. Primary efficacy and safety outcomes in relation to randomization, see Table. Conclusions: In patients with AF, a history of bleeding was associated with several risk factors for stroke and bleeding and, accordingly, a higher bleeding risk during anticoagulation. Benefits with apixaban vs warfarin as to stroke, mortality and major bleeding, are however consistent irrespective of bleeding history.

Risk Of Bleeding

BACKGROUND: Patients with atrial fibrillation (AF) who receive both antiplatelet (AP) and anticoagulant therapy are at markedly higher risk of bleeding. The ENGAGE AF-TIMI 48 trial showed that both the high- (HD) and low-dose (LD) regimens of the once-daily factor Xa inhibitor edoxaban (Edox) were as effective as well-managed warfarin (Warf) (median TTR 68.4%) in preventing stroke or systemic embolism (SEE) with significant reductions in major bleeding and cardiovascular mortality. In this study, we assessed the relative efficacy and safety of Edox as compared with Warf in patients with and without concomitant use of AP therapy. METHODS: This was a randomized, double-blind, double-dummy trial comparing HD (60 mg daily, reduced to 30mg in patients with anticipated increased drug exposure) and LD (30 mg daily, reduced to 15mg) Edox with Warf. Dual AP therapy was prohibited while receiving study drug. Cox proportional hazards models were performed stratified by AP use at 3 months with treatment as a covariate. RESULTS: Of the 21,105 patients, 4,912 (23%) were receiving AP therapy at 3 months (92% aspirin). Patients who received concomitant AP therapy had higher rates of major bleeding compared to patients who did not (Fig). Both Edox regimens had similar relative efficacy in preventing stroke or SEE compared with Warf regardless of concomitant AP use (P int >0.10 for both) with consistent reductions in major bleeding (HD Edox vs. Warf: P int =0.91; LD Edox vs. Warf: P int =0.59). In patients randomized to LD Edox, AP therapy was associated with a further reduction in the net clinical outcome of death, stroke, SEE, or major bleeding (P int =0.02) compared with Warf. CONCLUSIONS: Regardless of concomitant AP therapy, both doses of Edox significantly reduced bleeding compared to well-managed Warf. The safety profile of Edox may be particularly attractive in patients with AF who receive a combination of AP and anticoagulant therapy because of higher absolute risk of bleeding.

Abstract Background: Studies on the correlation between serum uric acid (SUA) and all-cause mortality in peritoneal dialysis (PD) patients were mainly based on the results of baseline SUA. We aimed to analyze the change of SUA level post PD, and the correlation between follow-up SUA and prognosis in PD patients. Methods: All patients who received PD catheterization and maintaining PD in our center from March 2, 2001 to March 8, 2017 were screened. Kaplan-Meier and Cox proportional-hazards regression models were used to analyze the effect of SUA levels on the risks of death. We graded SUA levels at baseline, 6 months, 12 months, 18 months and 24 months post PD by mean of SUA plus or minus a standard deviation as cut-off values, and compared all-cause and cardiovascular mortality among patients with different SUA grades. Results: A total of 1402 patients were included, 763 males (54.42%) and 639 females (45.58%). Their average age at PD start was 49.50±14.20 years. The SUA levels were 7.97±1.79mg/dl at baseline, 7.12±1.48mg/dl at 6 months, 7.05±1.33mg/dl at 12 months, 7.01±1.30mg/dl at 18 months, and 6.93±1.26mg/dl at 24 months. During median follow-up time of 31 (18, 49) months, 173 (12.34%) all-cause deaths occurred, including 68 (4.85%) cardiovascular deaths. There were no significant differences on all-cause mortality among groups with graded SUA levels at baseline, 12 months, 18 months and 24 months during follow-up or on cardiovascular mortality among groups with graded SUA levels at baseline, 6 months, 12 months, 18 months and 24 months during follow-up. At 6 months post PD，Kaplan Meier analysis showed there was significant difference on all-cause mortality among graded SUA levels (c2=11.315, P=0.010), and the all-cause mortality was lowest in grade of 5.65mg/dl≤SUA<7.13mg/dl. Conclusion: SUA level decreased during follow up post PD. At 6 months post PD, a grade of 5.65mg/dl≤SUA<7.13mg/dl was appropriate for better patients’ survival.

Abstract Background Relationship between atrial fibrillation (AF) and heart failure (HF) is often compared with proverbial question of which came first, the chicken or the egg. Some patients showing AF at the HF admission result in restoration of sinus rhythm (SR) at discharge. It is not well elucidated that the restoration into SR during hospitalization can render the preventive effect for rehospitalization. Purpose To investigate the impact of restoration into SR during hospitalization for readmission rate of the HF patients showing AF. Methods We enrolled consecutive 640 HF patients hospitalized from January 2015 to December 2015. Patients data were retrospectively investigated from medical record. Patients showing atrial fibrillation on admission but unrecognized ever were defined as “incident AF”; patients with AF diagnosed before admission were defined as “prevalent AF”. Primary endpoint was a composite of death from cardiovascular disease or hospitalization for worsening heart failure. Secondary endpoints were death from cardiovascular disease, unplanned hospitalization related to heart failure, and any hospitalization. Results During mean follow up of 19 months, 139 patients (22%) were categorized as incident AF and 145 patients (23%) were categorized as prevalent AF. Among 239 patients showing AF on admission, 44 patients were discharged in SR (39 patients in incident AF and 5 patients in prevalent AF). Among incident AF patients, the primary composite end point occurred in significantly fewer in those who discharged in SR (19% vs. 42% at 1-year; 23% vs. 53% at 2-year follow-up, p=0.005). To compare the risk factors related to readmission due to HF with the cox proportional-hazards model, AF only during hospitalization [Hazard Ratio (HR)=0.37, p<0.01] and prevalent AF (HR=1.67, p=0.04) was significantly associated. There was no significant difference depending on LVEF. Conclusion Newly diagnosed AF with restoration to SR during hospitalization was a good marker to forecast future prognosis.
