Epistaxis Versus Nonepistaxis Bleeding in Anticoagulated Patients With Atrial Fibrillation: Results From the ENGAGE AF-TIMI 48 Trial. J Am Heart Assoc 2025; 14:e031434. [PMID: 39791401 PMCID: PMC12054501 DOI: 10.1161/jaha.123.031434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 09/16/2024] [Indexed: 01/12/2025]
Abstract
BACKGROUND Epistaxis is common with antithrombotic therapy and is often troublesome to patients, yet its frequency, severity, and outcomes are poorly characterized. METHODS AND RESULTS Effective Anticoagulation with Factor Xa Next Generation in Atrial Fibrillation-Thrombolysis in Myocardial Infarction 48 (ENGAGE AF-TIMI 48) randomized 21 105 patients with atrial fibrillation and CHADS2 risk score ≥2 to higher-dose edoxaban regimen (60 mg daily, dose-reduced to 30 mg), lower-dose edoxaban regimen (30 mg, dose reduced to 15 mg, daily), or warfarin. Bleeds were adjudicated using International Society on Thrombosis and Haemostasis criteria. Patients with intracranial hemorrhage during follow-up were excluded; those with >1 bleeding event were categorized according to their most severe event. The safety cohort with interval censoring during drug interruption was analyzed. Proportions were compared using Pearson's chi-square test and treatment arms were compared using a Cox proportional hazards model. Among 5247 patients with a bleeding event, 1008 (19.2%) had epistaxis and 4239 (80.8%) had nonepistaxis bleeding. Epistaxis events were less severe than nonepistaxis bleeds (International Society on Thrombosis and Haemostasis major: 3.2% versus 20.7%; clinically relevant nonmajor: 64.7% versus 60.1%; minor: 32.1% versus 19.2%; P<0.001). Permanent drug discontinuation was similar following epistaxis versus nonepistaxis bleeding in patients with major (59.4% versus 53.6%; P=0.52) or clinically relevant nonmajor (32.5% versus 33.3%; P=0.70) bleeding but was significantly higher in patients with minor epistaxis versus other minor bleeds (33.3% versus 23.9%; P=0.001). Compared with warfarin, higher-dose edoxaban regimen had similar risk of epistaxis (hazard ratio [HR], 1.09 [95% CI, 0.95-1.26]), whereas lower-dose edoxaban regimen conferred reduced risk (HR, 0.73 [95% CI, 0.62-0.86]). CONCLUSIONS Epistaxis was frequent, and despite being overall less severe than nonepistaxis bleeding, was associated with similar rates of anticoagulant discontinuation. Compared with warfarin, lower-dose edoxaban regimen reduced the risk of epistaxis by 27% whereas higher-dose edoxaban regimen had no effect.

Abstract
BACKGROUND The impact of anticoagulants (AC) and antiplatelets (AP) on the management of acute epistaxis remains unclear. This study investigated the association between AC/AP therapy and treatment outcomes in patients with acute epistaxis. METHODOLOGY A retrospective analysis of patients presented to the otolaryngology emergency room with acute epistaxis (2014-2022). Patients were categorized based on their regular medications: AP, dual AP therapy (DAPT), new oral anticoagulants (NOAC), vitamin K antagonists (VKA), or no regular AC/AP use (control group). Outcome measures included rates of minor interventions (chemical or electrical cautery, nasal tamponade), major interventions (endoscopic ligation, embolization), recurrent emergency department visits, admission rates, and duration. RESULTS 786 patients were included with an average follow-up period of 52.56 ± 20.4 months. Compared to the control group, patients on AP, DAPT, or VKA had significantly higher rates of minor interventions (63.1% vs. 74.4%, 79.6%, and 77.3%, respectively, p < 0.05). DAPT users exhibited a higher rate of major interventions than the control (5.6% vs. 1.3%, p = 0.053). NOAC users showed no significant difference in minor interventions compared to control and required no major interventions. Both NOAC and VKA users had significantly higher rates of recurrent epistaxis events and prolonged hospitalization compared to the control (p < 0.01 and p < 0.05, respectively). CONCLUSIONS NOAC demonstrated more favorable outcomes than VKA in patients with acute epistaxis, and DAPT use was associated with an increased need for major interventions. These findings suggest a more conservative approach in NOAC users than other AC/AP agents.

Eur J Trauma Emerg Surg 2024; 50:543-550. [PMID: 38197899 PMCID: PMC11035474 DOI: 10.1007/s00068-023-02428-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2023] [Accepted: 12/11/2023] [Indexed: 01/11/2024]
Abstract
PURPOSE To investigate the effect of antithrombotics on the occurrence of maxillofacial haemorrhagic symptoms, and to determine if these haemorrhagic symptoms are predictors of maxillofacial fractures. METHOD A prospective cohort study was conducted of consecutive patients with maxillofacial trauma who had been admitted to the emergency department of four hospitals in the Netherlands. This study compared five haemorrhagic symptoms (peri-orbital haematoma, raccoon eyes, epistaxis, subconjunctival ecchymosis, and intra-oral haematoma) between patients not-using (NUA) and using (UA) of antithrombotics, and whether these maxillofacial haemorrhagic symptoms served as predictors for maxillofacial fractures. RESULTS Out of the 1005 patients, 812 (81%) belonged to the NUA group, and 193 (19%) to the UA group. UA patients exhibited higher frequencies of peri-orbital hematoma (54% vs. 39%, p < 0.001), raccoon eyes (10% vs. 5%, p = 0.01), and subconjunctival ecchymoses (16% vs. 7%, p < 0.001). In NUA, peri-orbital hematoma (OR = 2.5, p < 0.001), epistaxis (OR = 4.1, p < 0.001), subconjunctival ecchymosis (OR = 2.3, p = 0.02), and intra-oral hematoma (OR = 7.1, p < 0.001) were significant fracture predictors. Among UA, peri-orbital hematoma (OR = 2.2, p = 0.04), epistaxis (OR = 5.4, p < 0.001), subconjunctival ecchymosis (OR = 3.7, p = 0.008), and intra-oral hematoma (OR = 22.0, p < 0.001) were significant fracture predictors. CONCLUSION Maxillofacial haemorrhagic symptoms were observed more frequently in the UA group than in the NUA group. However, in both groups, maxillofacial haemorrhagic symptoms appear to be predictors of maxillofacial fractures. Caution is warranted in attributing these symptoms solely to antithrombotic use during emergency department assessments.

Abstract
BACKGROUND Although epistaxis is one of the most common side effects of oral anticoagulation, it is unclear whether epistaxis rates vary between different oral anticoagulants (OAC). OBJECTIVE To compare rates of clinically relevant epistaxis between OAC. METHODS Epistaxis event rates were compared between new users of apixaban, dabigatran, rivaroxaban, and warfarin in a nationwide population-based cohort study over a 5-year study period, 2014-2019. Data was collected from the Icelandic Medicine Registry and the five major hospitals in Iceland. Inverse probability weighting (IPW) was used to yield balanced baseline characteristics, and epistaxis rates were compared using Kaplan-Meier survival estimates and Cox regression. RESULTS During the study period, 2098 patients received apixaban, 474 dabigatran, 3106 rivaroxaban, and 1403 warfarin. In total, 93 patients presented with clinically relevant epistaxis, including 11 (12%) major epistaxis events and one fatal epistaxis episode. Furthermore, seven patients (9%) with non-major epistaxis later presented with major bleeding during the follow-up period. Warfarin use was associated with higher rates of epistaxis compared to apixaban (2.2 events per 100-person years (events/100-py) vs. 0.6 events/100-py, hazard ratio [HR] 4.22, 95% confidence interval [CI] 2.08-8.59, p < 0.001), rivaroxaban (2.2 events/100-py vs. 1.0 events/100-py, HR 2.26, 95% CI 1.28-4.01, p = 0.005), and dabigatran (2.2 events/100-py vs. no events, HR n/a, p < 0.001). CONCLUSION Warfarin treatment was associated with higher rates of clinically relevant epistaxis compared to direct oral anticoagulants.

Abstract
OBJECTIVE Epistaxis is the most common otolaryngological emergency and up to one third of patients in treated on an inpatient basis take oral anticoagulants (OAC). Direct oral anticoagulants (DOAC), an OAC subgroup, have been on the market since 2010 and are being increasingly prescribed due to the cardiological and haematological guidelines that favour them over vitamin K antagonists (VKA), the older of the OAC subgroups. The present study aims to investigate which subgroup of epistaxis patients taking OACs has a more favourable outcome. DESIGN/SETTING A systematic review and meta-analysis were performed according to the PRISMA 2020 statement using the PubMed and Cochrane Library databases. Continuous data were analysed and standardised mean difference (SMD) was calculated according to Hedges' g. Dichotomous data were analysed, and the Mantel-Haenszel method was applied to establish the odds ratio (OR). Heterogeneity was assessed according to the I2 statistics. MAIN OUTCOME/RESULTS A total of eight reports covering 1390 patients were included in the final synthesis. The pooled analysis demonstrated significantly shorter hospital stays in the DOAC group (SMD = -0.22, 95% CI-0.42 to -0.02, p = .03) and a significantly higher rate of posterior bleeding in the VKA group (OR = .39, 95% CI 0.23 to 0.68, p = .001). No statistically significant differences with regard to recurrence rates, admission rates, the need for transfusion or surgical intervention (p = .57, .12, .57 and .38 respectively) were found. CONCLUSION According to this meta-analysis, epistaxis patients taking DOACs have a more favourable outcome than patients taking VKAs.

Abstract
OBJECTIVES Epistaxis is frequently managed with intra-nasal packing devices, traditionally requiring patient admission. Current COVID-19 guidelines encourage ambulatory care where possible in this patient cohort. This paper aims to establish the impact of the Clinical Frailty Scale, anticoagulant/antiplatelet therapeutics and season variation on pre-pandemic admissions to help identify patients suitable for ambulatory epistaxis management. DESIGN Retrospective cohort study SETTING: Scottish Regional Health Board PARTICIPANTS: Adult patients attending secondary care with epistaxis between March 2019 and March 2020. MAIN OUTCOME MEASURES Likelihood of epistaxis hospital admission based on Clinical Frailty Scale. RESULTS 299 epistaxis presentations were identified, of which 122 (40.8%) required admission. Clinical Frailty Scale of ≥4 had an increased likelihood of admission (OR 3.15 (95% CI:1.94-5.16), P < .05). In the majority of presentations (66.2%), patients were taking either an antiplatelet or anticoagulant. Of these presentations, the use of an anticoagulant (OR: 2.00 (95% CI: 1.20-3.33), P < .05 and dual antiplatelet (OR: 2.82 (95% CI: 1.02-7.86), P < .05) demonstrated increased likelihood of admission. CONCLUSIONS We have shown that frailty increases the risk of admission in adult patients presenting with epistaxis. Clinical Frailty Scale (CFS) could be utilised in risk stratification to identify suitable patients for outpatient management. Patients with CFS ≤ 3 could be considered for outpatient management of their epistaxis. It is likely that patients with CFS ≥4 on anticoagulant or dual antiplatelet will require admission.

Abstract
OBJECTIVES To quantify the utilization of epistaxis procedures in the elderly population and assess whether the geographic variability of these procedures is associated with hypertension and direct oral anticoagulant (DOAC) use. METHODS A cross-sectional study was performed on publicly available Medicare procedure and beneficiary data from 2013 to 2016 for all epistaxis procedures categorized by Common Procedural Terminology (CPT). Epistaxis procedures were analyzed by state, complexity, and provider type. Pearson's correlation coefficient was calculated. RESULTS Over 4 years, 2 19 827 epistaxis procedures were performed on Medicare patients, 44.3% of which were categorized as simple (control of nasal hemorrhage: anterior simple or posterior primary). Otolaryngologists performed 92.6% of all epistaxis procedures. The frequency of epistaxis procedures performed by state ranged from 0.99 procedures per 10 000 Medicare beneficiaries (PP10K) in Hawaii to 25.7 PP10K in New Jersey. The percentage of epistaxis interventions categorized as complex (anterior complex, posterior subsequent, with nasal endoscopy, or open procedures) in each state varied from 0% in North Dakota to 72.6% in Hawaii. Epistaxis procedure utilization was weakly correlated with the prevalence of hypertension (R2 = 0.08, P = .04) and higher percentage of DOAC among all anticoagulants prescribed (R2 = 0.08, P = .04) in a state's Medicare population. Utilization of complex epistaxis interventions was not correlated with the prevalence of hypertension or DOAC use. CONCLUSIONS Otolaryngologists perform the vast majority of epistaxis procedures in the Medicare population. However, practice patterns vary across the United States. Hypertension and DOAC use are weakly associated with the utilization of epistaxis interventions.
