NON-ST elevated myocardial infarction , *BLOOD platelet transfusion , *RED blood cell transfusion , *CARDIOGENIC shock , *PERCUTANEOUS coronary intervention - Abstract
Patients with immune thrombocytopenia (ITP) admitted for non-ST elevation myocardial infarction (NSTEMI) present a unique therapeutic challenge due to the increased risk of bleeding with antiplatelet and anticoagulation therapies. There is limited evidence studying hospital mortality and complications in this population. The study included a patient cohort from the 2018–2021 National Inpatient Sample database. Propensity score matched NSTEMI patients with and without ITP using a 1:1 matching ratio. Outcomes analyzed were in-hospital mortality, rates of diagnostic angiogram, percutaneous coronary intervention (PCI), acute kidney injury (AKI), congestive heart failure (CHF), cardiogenic shock, cardiac arrest, mechanical ventilation, tracheal intubation, ventricular tachycardia (VT), ventricular fibrillation (VF), major bleeding, need for blood and platelet transfusion, length of stay (LOS), and total hospitalization charges. A total of 1,699,020 patients met inclusion criteria (660,490 females [39%], predominantly Caucasian 1,198,415 (70.5%); mean [SD] age 67, [3.1], including 2,615 (0.1%) patients with ITP. Following the propensity matching, 1,020 NSTEMI patients with and without ITP were matched. ITP patients had higher rates of inpatient mortality (aOR 1.98, 95% CI 1.11–3.50, p 0.02), cardiogenic shock, AKI, mechanical ventilation, tracheal intubation, red blood cells and platelet transfusions, longer LOS, and higher total hospitalization charges. The rates of diagnostic angiogram, PCI, CHF, VT, VF, and major bleeding were not different between the two groups. Patients with ITP demonstrated higher odds of in-hospital mortality for NSTEMI and need for platelet transfusion with no difference in rates of diagnostic angiogram or PCI. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Treating cancer-associated venous thromboembolism (CAT) with anticoagulation prevents recurrent venous thromboembolism (rVTE), but increases bleeding risk. Objectives: To compare incidence of rVTE, major bleeding, and all-cause mortality for rivaroxaban versus low molecular weight heparin (LMWH) in patients with CAT. Methods: We developed a cohort study using Swedish national registers 2013–2019. Patients with CAT (venous thromboembolism within 6 months of cancer diagnosis) were included. Those with other indications or with high bleeding risk cancers were excluded (according to guidelines). Follow-up was from index-CAT until outcome, death, emigration, or end of study. Incidence rates (IR) per 1000 person-years with 95% confidence interval (CI) and propensity score overlap-weighted hazard ratios (HRs) for rivaroxaban versus LMWH were estimated. Results: We included 283 patients on rivaroxaban and 5181 on LMWH. The IR for rVTE was 68.7 (95% CI 40.0–109.9) for rivaroxaban, compared with 91.6 (95% CI 81.9–102.0) for LMWH, with adjusted HR 0.77 (95% CI 0.43–1.35). The IR for major bleeding was 23.5 (95% CI 8.6–51.1) for rivaroxaban versus 49.2 (95% CI 42.3–56.9) for LMWH, with adjusted HR 0.62 (95% CI 0.26–1.49). The IR for all-cause mortality was 146.8 (95% CI 103.9–201.5) for rivaroxaban and 565.6 (95% CI 541.8–590.2) for LMWH with adjusted HR 0.48 (95% CI 0.34–0.67). Conclusions: Rivaroxaban performed similarly to LMWH for patients with CAT for rVTE and major bleeding. An all-cause mortality benefit was observed for rivaroxaban which potentially may be attributed to residual confounding. Trial registration number: NCT05150938 (Registered 9 December 2021). Highlights: Treating cancer-associated venous thromboembolism with anticoagulation prevents recurrent VTE, but may increase the risk of bleeding. DOACs have easier administration and proven higher treatment adherence compared to LMWH. Excluding cancer with high risk of bleeding, rivaroxaban performed similarly to LMWH for patients with cancer and VTE for recurrent VTE and major bleeding. An all-cause mortality benefit was observed for rivaroxaban compared to LMWH which potentially may be attributed to residual confounding. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: Bleeding is an important health outcome of interest in epidemiological studies. We aimed to develop and validate rule‐based algorithms to identify (1) major bleeding and (2) all clinically relevant bleeding (CRB) (composite of major and all clinically relevant nonmajor bleeding) within real‐world electronic healthcare data. Methods: We took a random sample (n = 1630) of inpatient admissions to Singapore public healthcare institutions in 2019 and 2020, stratifying by hospital and year. We included patients of all age groups, sex, and ethnicities. Presence of major bleeding and CRB were ascertained by two annotators through chart review. A total of 630 and 1000 records were used for algorithm development and validation, respectively. We formulated two algorithms: sensitivity‐ and positive predictive value (PPV)‐optimized algorithms. A combination of hemoglobin test patterns and diagnosis codes were used in the final algorithms. Results: During validation, diagnosis codes alone yielded low sensitivities for major bleeding (0.16) and CRB (0.24), although specificities and PPV were high (>0.97). For major bleeding, the sensitivity‐optimized algorithm had much higher sensitivity and negative predictive values (NPVs) (sensitivity = 0.94, NPV = 1.00), however false positive rates were also relatively high (specificity = 0.90, PPV = 0.34). PPV‐optimized algorithm had improved specificity and PPV (specificity = 0.96, PPV = 0.52), with little reduction in sensitivity and NPV (sensitivity = 0.88, NPV = 0.99). For CRB events, our algorithms had lower sensitivities (0.50–0.56). Conclusions: The use of diagnosis codes alone misses many genuine major bleeding events. We have developed major bleeding algorithms with high sensitivities, which can ascertain events within populations of interest. [ABSTRACT FROM AUTHOR]

ARTESiA (Apixaban for the Reduction of Thrombo-Embolism in Patients With Device-Detected Sub-Clinical Atrial Fibrillation) demonstrated that apixaban, compared with aspirin, significantly reduced stroke and systemic embolism (SE) but increased major bleeding in patients with subclinical atrial fibrillation. To help inform decision making, the authors evaluated the efficacy and safety of apixaban according to baseline CHA 2 DS 2 -VASc score. We performed a subgroup analysis according to baseline CHA 2 DS 2 -VASc score and assessed both the relative and absolute differences in stroke/SE and major bleeding. Baseline CHA 2 DS 2 -VASc scores were <4 in 1,578 (39.4%) patients, 4 in 1,349 (33.6%), and >4 in 1,085 (27.0%). For patients with CHA 2 DS 2 -VASc >4, the rate of stroke was 0.98%/year with apixaban and 2.25%/year with aspirin; compared with aspirin, apixaban prevented 1.28 (95% CI: 0.43-2.12) strokes/SE per 100 patient-years and caused 0.68 (95% CI: −0.23 to 1.57) major bleeds. For CHA 2 DS 2 -VASc <4, the stroke/SE rate was 0.85%/year with apixaban and 0.97%/year with aspirin. Apixaban prevented 0.12 (95% CI: −0.38 to 0.62) strokes/SE per 100 patient-years and caused 0.33 (95% CI: −0.27 to 0.92) major bleeds. For patients with CHA 2 DS 2 -VASc =4, apixaban prevented 0.32 (95% CI: −0.16 to 0.79) strokes/SE per 100 patient-years and caused 0.28 (95% CI: −0.30 to 0.86) major bleeds. One in 4 patients in ARTESiA with subclinical atrial fibrillation had a CHA 2 DS 2 -VASc score >4 and a stroke/SE risk of 2.2% per year. For these patients, the benefits of treatment with apixaban in preventing stroke/SE are greater than the risks. The opposite is true for patients with CHA 2 DS 2 -VASc score <4. A substantial intermediate group (CHA 2 DS 2 -VASc =4) exists in which patient preferences will inform treatment decisions.

Aims: Our aims were to describe the clinical characteristics, adverse clinical events, healthcare resource utilization (HCRU) and costs of patients with major bleeding during direct Factor Xa inhibitor (FXai) use. Methods: This is a retrospective cohort study that included secondary data from computerized health records of seven Spanish Autonomous Communities. Patients with a first major bleeding during treatment with a direct FXai were analyzed during a 3-year period. Results: Of 8972 patients taking a direct FXai, 470 (5.24%) had major bleeding (mean age (SD) 77.93 (9.71) years, 61.06% women). The most frequent indications for using FXais were atrial fibrillation (78.09%) and venous thromboembolism (17.66%). Among those with major bleeding, 88.94% presented with gastrointestinal bleeding, 6.81% intracranial bleeding, 2.13% trauma-related bleeding and 4.26% other major bleeding. Prothrombin complex concentrates were used in 63.19%, followed by transfusion of blood products (20.21%) and Factor VIIa (7.66%). In total, 4.26% of patients died in the hospital due to the first major bleeding. At the study end (after 3-year follow-up), 28.94% of the patients had died, 12.34% had a myocardial infarction and 9.15% an ischemic stroke. At year 3, overall bleeding cost was EUR 5,816,930.5, of which 79.74% accounted for in-hospital costs to treat the bleeding episode. Conclusions: Despite the use of replacement agents being high, major events were common, with a 29% mortality at the end of the follow up, and HCRU and costs were high, evidencing the need for new reversal treatment strategies.

- Abstract
Patients with peripheral artery disease (PAD) who undergo lower extremity revascularization (LER) are at high risk for cardiovascular and limb-related ischemic events. The role of antithrombotic therapy is to prevent thrombotic complications, but this requires balancing increased risk of bleeding events. The dual pathway inhibition (DPI) strategy including aspirin and low-dose rivaroxaban after LER has been shown to reduce major adverse cardiovascular and limb-related events without significant differences in major bleeding. There is now a need to implement the broad adoption of DPI therapy in PAD patients who have undergone LER in routine practice. [ABSTRACT FROM AUTHOR]

- Abstract
To evaluate the safety of cangrelor administered concurrently with heparin or bivalirudin in patients on mechanical circulatory support. A single-center, retrospective cohort study of adult patients consecutively admitted between January 2016 and October 2020. A tertiary medical center. Adult patients admitted to the cardiovascular intensive care unit put on mechanical circulatory support for acute myocardial infarction (AMI) or non-AMI indications. Patients who received cangrelor underwent percutaneous coronary intervention with stenting during the index event or within the last year. None. The primary outcome was the incidence of major bleeding, defined by the Extracorporeal Life Support Organization criteria, in patients with mechanical circulatory support receiving cangrelor plus anticoagulation with heparin or bivalirudin with or without aspirin versus patients who did not receive cangrelor. Sixty-eight patients were included in the study. Twenty-nine patients received cangrelor, and 39 did not. Cangrelor was not associated with an increase in major bleeding; however, the CI was wide (adjusted hazard ratio 1.93, 95% CI 0.61-6.11; p = 0.262). Patients receiving cangrelor did not appear to be at higher risk of major bleeding compared to patients not receiving cangrelor. Larger trials should be conducted to better evaluate the safety of cangrelor in patients with mechanical circulatory support. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: Outcomes from randomized controlled trials (RCTs) inform the latest recommendations on percutaneous coronary intervention (PCI) management of a short period of oral anticoagulation (OAC), a P2Y
12 receptor inhibitor, and aspirin for 1 week or until hospital discharge in patients with atrial fibrillation (AF) undergoing PCI, and up to 4 weeks in individuals considered to be at high-risk for ischemic events, followed by discontinuation of aspirin and continuation of OAC and a P2Y12 inhibitor for up to 12 months. Methods: We examined and summarized the outcomes of bleeding and major adverse cardiac events (MACEs) from RCTs and meta-analyses, published between 2013 and 2022, comparing therapy with OAC and a P2Y12 inhibitor with and without aspirin in AF patients undergoing PCI with stenting. Results: Data comparing dual therapy with OAC and a P2Y12 inhibitor alone to triple therapy with OAC, a P2Y12 inhibitor, and aspirin with respect to the risks of MACEs, including stent thrombosis within the first 30 days, are underpowered and inconclusive. The addition of aspirin does not appear to be associated with a decreased risk of ischemic events, even in patients with high-risk CHA2 DS2 -VASc scores, but does significantly increase bleeding hazards. The increased safety of newer generation drug-eluting stents may have further minimized any theoretical anti-ischemic benefits of aspirin. The possible attenuation of the pleiotropic effects of concomitant cardiovascular medications by aspirin may also have been a contributing factor. Conclusion: The addition of aspirin to OAC and a P2Y12 inhibitor is likely associated with a net clinical harm in patients with AF who undergo PCI with stenting, even within the first 1–4 weeks after PCI. Revisiting the guideline recommendations to administer aspirin in this timeframe may be warranted. [ABSTRACT FROM AUTHOR]- Published

Background: This systematic review aims to evaluate and compare differences in clinical outcomes for adult patients diagnosed with ISSPE who were managed with anticoagulation vs clinical surveillance. Methods: PubMed, Embase, ProQuest, Cochrane, and Google Scholar were searched to identify studies evaluating the use of anticoagulation and/or clinical surveillance in patients diagnosed with ISSPE. The search included studies published up to August 3, 2023. Outcomes of interest included 90-day recurrent venous thromboembolism (VTE), major bleeding, and all-cause mortality rates. Results: Ten studies were included with a total of 1224 patients. Of these patients, 791 were treated with anticoagulation and 433 underwent surveillance. Studies found no difference in recurrent VTE rates, with the majority of studies reporting no recurrence. Of the studies that reported VTE recurrence, rates were.5% to 1.4% for the anticoagulation groups and 3.1% to 3.2% for the surveillance groups. Major bleeding rates were also similar. In anticoagulated patients, major bleeding rates ranged from 1% to 10%. In clinical surveillance patients, the majority found no rate of major bleeding, with 2 studies reporting rates of.8% to 3.2%. Mortality rates ranged widely with no significant differences reported. Conclusion: Clinical surveillance appears to be a safe and effective alternative to anticoagulation in patients with ISSPE. Ninety-day rates of recurrent VTE, major bleeding, and mortality were comparable between groups. These findings highlight the need for updated practice management guidelines to improve patient outcomes. [ABSTRACT FROM AUTHOR]

Previous meta‐analyses assessed andexanet alfa (AA) or prothrombin complex concentrate (PCC) products for the treatment of Factor Xa inhibitor (FXaI)‐associated major bleeding. However, they did not include recent studies or assess the impact of the risk of bias. We conducted a systematic review with meta‐analysis on the effectiveness of AA versus PCC products for FXaI‐associated major bleeding, inclusive of the studies' risk of bias. PubMed and Embase were searched for comparative studies assessing major bleeding in patients using FXaI who received AA or PCC. We used the Methodological Index for NOn‐Randomized Studies (MINORS) checklist and one question from the Joanna Briggs Institute (JBI) Critical Appraisal of Case Series tool to assess the risk of bias. Random‐effects meta‐analyses were performed to provide a pooled estimate for the effect of AA versus PCC products on hemostatic efficacy, in‐hospital mortality, 30‐day mortality, and thrombotic events. Low–moderate risk of bias studies were meta‐analyzed separately, as well as combined with high risk of bias studies. Eighteen comparative evaluations of AA versus PCC were identified. Twenty‐eight percent of the studies (n = 5) had low–moderate risk and 72% (n = 13) had a high risk of bias. Studies with low–moderate risk of bias suggested improvements in hemostatic efficacy [Odds Ratio (OR) 2.72 (95% Confidence Interval (CI): 1.15–6.44); one study], lower in‐hospital mortality [OR 0.48 (95% CI: 0.38–0.61); three studies], and reduced 30‐day mortality [OR 0.49 (95% CI: 0.30–0.80); two studies] when AA was used versus PCC products. When studies were included regardless of the risk of bias, pooled effects showed improvements in hemostatic efficacy [OR 1.36 (95% CI: 1.01–1.84); 12 studies] and reductions in 30‐day mortality [OR 0.53 (95% CI: 0.37–0.76); six studies] for AA versus PCC. The difference in thrombotic events with AA versus PCC was not statistically significant in the low–moderate, high, or combined risk of bias groups. The evidence from low–moderate quality real‐world studies suggests that AA is superior to PCC in enhancing hemostatic efficacy and reducing in‐hospital and 30‐day mortality. When studies are assessed regardless of the risk of bias, the pooled hemostatic efficacy and 30‐day mortality risk remain significantly better with AA versus PCC. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Polypharmacy is commonly observed in atrial fibrillation (AF) and is associated with poorer clinical outcomes. Our study aimed to elucidate the polypharmacy prevalence, its associated risk factors, and its relationship with adverse clinical outcomes using a 'real-world' database. Methods: This study included 451,368 subjects without prior history of AF (median age, 54 [interquartile range, 48.0-63.0] years; 207,748 [46.0%] female) from the Korea National Health Insurance Service-Health Screening (NHIS-HealS) database between 2002 and 2013. All concomitant medications prescribed were collected, and the intake of five or more concomitant drugs was defined as polypharmacy. During the follow-up, all-cause death, major bleeding events, transient ischemic attack (TIA) or ischemic stroke, and admission due to worsened heart failure were recorded. Results: Based on up to 7.7 (6.8-8.3) years of follow-up and 768,306 person-years, there were 12,241 cases of new-onset AF identified. Among patients with new-onset AF (40.0% females, median age 63.0 [54.0-70.0] years), the polypharmacy prevalence was 30.9% (3784). For newly diagnosed AF, factors, such as advanced age (with each increase of 10 years, odds ratios (OR) 1.32, 95% confidence interval (CI) 1.26-1.40), hypertension (OR 4.00, 95% CI 3.62-4.43), diabetes mellitus (OR 3.25, 95% CI 2.86-3.70), chronic obstructive pulmonary disease (COPD) (OR 3.00, 95% CI 2.51-3.57), TIA/ischemic stroke (OR 2.36, 95% CI 2.03-2.73), dementia history (OR 2.30, 95% CI 1.06-4.98), end-stage renal disease (ESRD) or chronic kidney disease (CKD) (OR 1.97, 95% CI 1.38-2.82), and heart failure (OR 1.95, 95% CI 1.69-2.26), were found to be independently correlated with the incidence of polypharmacy. Polypharmacy significantly increased the incidence and risk of major bleeding (adjusted hazard ratio (aHR) 1.26, 95% CI 1.12-1.41). The study observed a statistically significant increase in the incidence of all-cause mortality, however, the risk for all-cause mortality elevated but did not show significance (aHR 1.11, 95% CI 0.99-1.24). The risk of stroke and admission for heart failure did not change with polypharmacy. Conclusions: In our investigation using data from a nationwide database, polypharmacy was widespread in new-onset AF population and was related to major bleeding events. However, polypharmacy does not serve as an independent risk factor for adverse outcomes, with exception of major bleeding event. For AF patients, ensuring tailored medication for comorbidities as well as reducing polypharmacy are essential considerations. [ABSTRACT FROM AUTHOR]

Acute ischemic stroke (AIS) is the most common type of stroke and requires immediate reperfusion. Current acute reperfusion therapies comprise the administration of intravenous thrombolysis and/or endovascular thrombectomy. Although these acute reperfusion therapies are increasingly successful, optimized secondary antithrombotic treatment remains warranted, specifically to reduce the risk of major bleeding complications. In the development of AIS, coagulation and platelet activation play crucial roles by driving occlusive clot formation. Recent studies implicated that the intrinsic route of coagulation plays a more prominent role in this development, however, this is not fully understood yet. Next to the acute treatments, antithrombotic therapy, consisting of anticoagulants and/or antiplatelet therapy, is successfully used for primary and secondary prevention of AIS but at the cost of increased bleeding complications. Therefore, better understanding the interplay between the different pathways involved in the pathophysiology of AIS might provide new insights that could lead to novel treatment strategies. This narrative review focuses on the processes of platelet activation and coagulation in AIS, and the most common antithrombotic agents in primary and secondary prevention of AIS. Furthermore, we provide an overview of promising novel antithrombotic agents that could be used to improve in both acute treatment and stroke prevention. • Intrinsic activation is suggested to have a prevalent role in acute ischemic stroke. • Current anticoagulant therapies are associated with up to 10 % of major bleedings. • Current anticoagulant therapies are associated with up to 2 % of hemorrhagic strokes. • New antithrombotic therapies are needed for primary and secondary prevention of AIS.

Calcific aortic stenosis is the principal indication for transcatheter aortic valve replacement (TAVR). Comorbid mitral annular calcification (MAC) is often present in patients undergoing TAVR. Limited data exist on the impact of MAC on TAVR outcomes. We conducted a systematic review and meta-analysis to explore the effects of MAC and concomitant mitral valve dysfunction (MVD) on TAVR outcomes. A comprehensive literature review was conducted using PubMed, Embase, Google Scholar, ClinicalTrials.gov, Scopus, and OVID for studies until March 20, 2023. Using the random-effects Mantel-Haenszel method, we calculated pooled risk ratios (RRs) and their corresponding 95 % confidence intervals (CIs) for all dichotomous variables. Six studies comprising 5822 patients (2541 with MAC [severe MAC (>4 mm thickness) 583; non-severe MAC 1958; 400 with MVD; and 1071 without MVD], 3281 without MAC) met inclusion criteria. At 30 days and 1 year, no significant differences were observed between the overall MAC and no MAC groups in terms of mortality, stroke, and permanent pacemaker implantation. However, MAC with MVD was associated with a higher risk of all-cause mortality compared to MAC without MVD at 30 days (RR = 3.43, 95 % CI 2.04–5.76, P < 0.00001) and at 1 year (RR = 2.44, 95 % CI 1.85–3.20, P < 0.00001). Moreover, the risk of cardiovascular mortality was higher in patients with MAC and MVD compared to those with MAC alone (RR = 2.77, 95 % CI 1.89–4.06, P < 0.00001). Additionally, patients with severe MAC had a higher risk of major bleeding at 30 days compared to the non-severe MAC group (RR = 1.33, 95 % CI 1.04–1.69, P = 0.02). TAVR appears to be safe in patients with non-severe MAC, but severe MAC is associated with a higher risk of major bleeding and concomitant MVD increases the mortality risk in patients undergoing TAVR. [Display omitted] • This study explores the impact of mitral annular calcification (MAC) and concomitant mitral valve dysfunction (MVD) on transcatheter aortic valve replacement (TAVR) outcomes. • Severe MAC was associated with a higher risk of major bleeding, while MAC with MVD increased the risk of all-cause and cardiovascular mortality. • TAVR was generally safe for patients with non-severe MAC. • The findings of this review highlight the importance of evaluating for MVD in patients with MAC undergoing pre-TAVR workup.

- Abstract
The OAC
3 -PAD score was developed to predict bleeding risk in patients with lower extremity peripheral arterial disease (PAD), but its performance in concomitant international cohorts is largely unknown. This study aimed to validate the OAC3 -PAD score in an unselected nationwide population of patients undergoing invasive treatment for symptomatic PAD. This was a nationwide cohort study including all patients who underwent a first revascularisation procedure or major amputation for symptomatic PAD in Denmark from 2000 – 2021. The study population was stratified based on OAC3 -PAD score, and the one year risk of major bleeding was assessed, accounting for the competing risk of death. The score performance was evaluated using calibration plots, C statistic, Brier score, and the index of prediction accuracy (IPA). A total of 52 016 patients were included (mean age 71 years, 43.8% female). The one year risk of major bleeding increased with higher OAC3 -PAD score, ranging from 1.6% (95% confidence interval [CI] 1.4 – 1.8%) to 2.3% (95% CI 2.0 – 2.5%), 3.5% (95% CI 3.2 – 3.8%), and 5.2% (95% CI 4.8 – 5.6%) for patients with low, low moderate, moderate high, and high score, respectively. Using patients with low risk as reference, the OAC3 -PAD score effectively categorised patients, demonstrating statistically significant differences in bleeding risk across strata. However, the score showed modest discriminative performance, with a C statistic of 65% (95% CI 63 – 66%) and a Brier score of 2.6% (95% CI 2.5 – 2.7%). Nevertheless, it performed significantly better than the null model, as indicated by an IPA of 3.1%. Among patients who underwent invasive treatment for symptomatic PAD in routine care, the OAC3 -PAD score was associated with greater risk of major bleeding with increasing score level. However, its discriminatory ability was modest, and the clinical utility remains to be determined. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background: Direct oral anticoagulants (DOACs) are the preferred treatment for venous thromboembolism (VTE). However, DOAC use in patients with a BMI greater than 40 kg/m
2 has not been well studied despite the growing prevalence of obesity, and current literature is often underpowered. Methods: This multicenter, retrospective, observational study evaluated patients 18 years and older who received DOACs for acute VTE treatment. Patients receiving DOACs for recurrent VTE or for failure of another agent were excluded. The primary efficacy outcome was recurrent VTE and the primary safety outcome was major bleeding within 12 months (or one month after stopping anticoagulation therapy). A propensity score analysis was performed to balance patient characteristics and evaluate the primary endpoints by BMI group. Time-to-event outcomes were analyzed using weighted Kaplan-Meier curves. Results: There were 165 patients with a BMI of at least 40 kg/m2 and 320 patients with a BMI less than 40 kg/m2 . The majority received apixaban (373, 77%). Recurrent VTE occurred in 5 (3.0%) and 13 (4.1%) of patients in the higher and lower BMI groups, respectively (adjusted OR: 0.66; 95% CI: 0.16–2.69). Major bleeding occurred in 5 (3.0%) and 15 (4.7%) of patients in the higher and lower BMI groups, respectively (adjusted OR: 1.19; 95% CI: 0.36–3.92). Conclusion: There was no significant difference in VTE recurrence or major bleeding related to BMI among patients treated with DOACs. This study showed that DOACs may be a safe and effective VTE treatment option in patients with obesity. Key points: Data supporting the use of direct oral anticoagulants (DOACs) for the treatment of venous thromboembolism (VTE) in patients with obesity are limited. This multicenter analysis aimed to evaluate the effectiveness and safety of DOACs in patients with and without obesity. The majority of patients received apixaban. VTE recurrence and rates of major bleeding were not different between patients with a BMI of at least 40 kg/m2 compared to a BMI less than 40 kg/m2 . This study adds to the growing body of evidence supporting the use of DOACs, particularly apixaban, in patients with obesity, although future prospective trials and additional data in patients at extremes of body weight will be useful.

Background There have been limited data on the changes in clinical outcomes after the introduction of direct oral anticoagulants (DOACs) for venous thromboembolism (VTE) in real clinical practice. We evaluated the changes in management strategies and long‐term outcomes from the warfarin era to the DOAC era. Methods and Results We compared the 2 series of multicenter COMMAND VTE (Contemporary Management and Outcomes in Patients With Venous Thromboembolism) registries in Japan enrolling consecutive patients with acute symptomatic VTE: Registry 1: 3027 patients in the warfarin era (2010–2014) and Registry 2: 5197 patients in the DOAC era (2015–2020). The prevalence of DOAC use increased more in Registry 2 than in the Registry 1 (Registry 1: 2.6% versus Registry 2: 79%, P

In the European Guideline on Management of Major Bleeding and Coagulopathy Following Trauma updated recently, there are 39 clinical practice recommendations that follow an approximate temporal path for management of the bleeding trauma patient, with recommendations grouped behind key decision points, including initial resuscitation and prevention of further bleeding, diagnosis and monitoring of bleeding, rapid control of bleeding, initial management of bleeding and coagulopathy, further goal-directed coagulation management, management of antithrombotic agents, thromboprophylaxis, guideline implementation and quality control, as welll as the management of tissue oxygenation, volume, fluids and temperature. In this paper, we introduce the recommendations and rationale of the guideline and add some newly published clinical study evidence. These information would be very helpful to the development and training of the guidelines or protocols for the management of the trauma patient with major haemorrhage and coagulopathy in China.

• There is substantial heterogeneity in the risk of VTE in acute medically ill patients. • History of VTE and cancer related hospitalization represent profiles with a high risk of VTE. • Enoxaparin prophylaxis mostly ended at, or 1–2 days before hospital discharge. • More than 90 % of VTE events occurred while not on background prophylaxis. We aimed to describe the event rates and risk-factors for symptomatic venous thromboembolism (VTE) and major bleeding in a population of hospitalized acutely ill medical patients. Patients ≥40 years old and hospitalized for acute medical illness who initiated enoxaparin prophylaxis were selected from the US Optum research database. Rates of symptomatic VTE and major bleeding at 90-days were estimated via the Kaplan-Meier (KM) method. Risk factors were identified via the Cox proportional hazards model. A total of 123,022 patients met the selection criteria. The KM rates of VTE and major bleeding at 90-days were 3.5 % and 2.2 %, respectively. Among subgroups, the risk of VTE varied from 3.0 % in patients with ischemic stroke to 6.9 % in patients with a cancer-related hospitalization, and the risk of major bleeding varied from 1.9 % in patients with inflammatory conditions to 3.6 % in patients with ischemic stroke. Key risk factors for VTE were prior VTE (HR=4.15, 95 % confidence interval [CI] 3.80–4.53), cancer-related hospitalization (HR=2.35, 95 % CI 2.10–2.64), and thrombophilia (HR=1.64, 95 % CI 1.29–2.08). Key risk factors for major bleeding were history of major bleeding (HR=2.17, 95 % CI 1.72–2.74), history of non-major bleeding (HR=2.46, 95 % CI 2.24–2.70), and hospitalization for ischemic stroke (2.42, 95 % CI 2.11–2.78). There is substantial heterogeneity in the event rates for VTE and major bleeding in acute medically ill patients. History of VTE and cancer related hospitalization represent profiles with a high risk of VTE, where continued VTE prophylaxis may be warranted. [ABSTRACT FROM AUTHOR]

Introduction: Bleeding after heart valve surgery is a serious clinical challenge. Hypocalcemia has been associated with the extent of bleeding in patients with spontaneous intracerebral hemorrhage. However, the association between blood calcium levels and bleeding extent in heart valve replacement patients has not been clearly established. This study aimed at determining the association between blood calcium levels and perioperative hemorrhage after heart valve replacement therapy. Methods: Based on preoperative blood calcium levels, patients were grouped into the hypocalcemia group and normocalcemia group. Postoperative bleeding, blood product use, and complications were monitored during hospitalization. The association between blood calcium levels and major bleeding was determined by multivariable logistic regression models. Results: In the first 12 h after surgery, bleeding in hypocalcemia group was significantly larger than that of the normocalcemia group (338 ± 234 mL vs 232 ± 96 mL; p =.024). The outcome was the same when the overall chest tube output was considered (950 ± 447 mL vs 738 ± 220 mL; p =.038). The incidence of major bleeding was 65.91% in the hypocalcemia group and 18.97% in the normocalcemia group (p =.001). Postoperative complications in the two groups were similar. After adjusting for multiple covariates, the adjusted odds ratios (OR) for participants in hypocalcemia group was 10.01 (95% CI 3.35–34.82), compared with that in normocalcemia group (p <.001). Conclusion: In patients undergoing heart valve surgery, preoperative blood concentrations of calcium are associated with postoperative blood loss. Hypocalcemia before operation may increase the risk of postoperative bleeding. When patients with valvular heart disease present with hypocalcemia before surgery, prompt intervention may lead to better control of postoperative bleeding. [ABSTRACT FROM AUTHOR]

When high thromboembolic and bleeding risks coexist, the former tends to influence physicians' decision making for anti-coagulation therapy. However, the ideal is to weigh the risk of major bleeding and stroke together to ensure effective anti-coagulation treatment, which is a limitation of traditional guideline recommended CHA2DS2-VASc and HAS-BLED. This meta-analysis assesses the performance of the two new scores — ABC and GARFIELD-AF compared to CHA2DS2-VASc and HAS-BLED for major bleeding and stroke outcomes in patients with atrial fibrillation (AF) on anticoagulation therapy. MEDLINE and Cochrane central were searched from 2010 to February 2023 that compared GARFIELD-AF and/or ABC with CHA2DS2-VASc and/or HAS-BLED scores using C-statistics to assess their discriminative ability. 12 studies were included in this meta-analysis. When assessing stroke risk prediction, GARFIELD-AF stroke (C-Statistic: 0.71; 95 % CI: 0.70–0.72; I2 = 0 %, p < 0.05) was found to be significantly better than ABC-stroke (C-Statistic: 0.67; 95 % CI: 0.65–0.68; I2 = 0 %, p < 0.05), and CHA2DS2-VASc (C-Statistic: 0.64; 95 % CI: 0.60–0.67; I2 = 92 %, p < 0.05). Additionally, when assessing bleeding risk prediction, ABC-bleeding (C-Statistic: 0.66; 95 % CI: 0.61–0.70; I2 = 84 %, p < 0.05), GARFIELD-AF (C-Statistic: 0.64; 95 % CI: 0.60–0.68; I2 = 95 %, p < 0.05), and HAS-BLED (C-Statistic: 0.64; 95 % CI: 0.62–0.66; I2 = 85 %, p < 0.05) all showed equivalent performances. The GARFIELD-AF stroke score showed superior performance to the well-established CHA2DS2-VASc score as well as the ABC-stroke score. Therefore, new guidelines should favor GARFIELD-AF use in clinical practice. [ABSTRACT FROM AUTHOR]

This umbrella review synthesizes data from 17 meta-analyses investigating the comparative outcomes of catheter ablation (CA) and medical treatment (MT) for atrial fibrillation (AF). Outcomes assessed were mortality, risk of hospitalization, AF recurrence, cardiovascular events, pulmonary vein stenosis, major bleeding, and changes in left ventricular ejection fraction (LVEF) and MLHFQ score. The findings indicate that CA significantly reduces overall mortality and cardiovascular hospitalization with high strength of evidence. The risk of AF recurrence was notably lower with CA, with moderate strength of evidence. Two associations reported an increased risk of pulmonary vein stenosis and major bleeding with CA, supported by high strength of evidence. Improved LVEF and a positive change in MLHFQ were also associated with CA. Among patients with AF and heart failure, CA appears superior to MT for reducing mortality, improving LVEF, and reducing cardiovascular rehospitalizations. In nonspecific populations, CA reduced mortality and improved LVEF but had higher complication rates. Our findings suggest that CA might offer significant benefits in managing AF, particularly in patients with heart failure. However, the risk of complications, including pulmonary vein stenosis and major bleeding, is notable. Further research in understudied populations may help refine these conclusions.

Background: Real-world evidence on direct oral anticoagulant outcomes among Non-Valvular Atrial Fibrillation (NVAF) patients is limited. We aimed to evaluate stroke/systemic embolism (SE) and major bleeding (MB) risks among NVAF patients continuing or switching to different oral anticoagulants. Methods: Using Optum's de-identified Clinformatics® Data Mart Database, we identified NVAF patients initiating apixaban or rivaroxaban between 1 January 2013 and 31 December 2021. Patients switching therapies within 30 days before or 90 days after discontinuing their initial DOAC and those who continued initial therapy were included. The index date was the switch date for switchers, while continuers were assigned a hypothetic index date. Switchers and continuers were propensity score matched based on pre-index characteristics. Results: Among 167,868 apixaban and 65,888 rivaroxaban initiators, 2900 apixaban-to-rivaroxaban switchers were matched with 14,500 apixaban continuers, and 2873 rivaroxaban-to-apixaban switchers were matched with 14,365 rivaroxaban continuers. Apixaban-to-rivaroxaban switching was associated with higher stroke/SE risk (HR: 1.99, 95% CI: 1.38–2.88) and MB risk (HR:1.80, 95% CI: 1.46–2.23) than continuing apixaban. Rivaroxaban-to-apixaban switching had similar stroke/SE risk (HR: 0.74, 95% CI: 0.45–1.22) but lower MB risk (HR: 0.49, 95% CI: 0.38–0.65) than continuing rivaroxaban. Conclusions: These findings may aid physicians and patients in making informed decisions when considering a switch between apixaban and rivaroxaban. [ABSTRACT FROM AUTHOR]

- Abstract
Background and aims: Liver diseases play an important role in the development and progression of atrial fibrillation (AF). The Fibrosis-4 (FIB-4) index is a non-invasive score recommended for detecting liver fibrosis. Since the association between liver fibrosis and outcomes of AF patients is still not well defined, we aim to analyze prognosis impact of FIB-4 index in those patients. Methods: A retrospective population-based cohort study was performed with 12,870 unselected patients from a single health area in Spain with AF from 2014 to 2019. Cox regression models were used to estimate the association of FIB-4 index with mortality. The association with ischemic stroke (IS), major bleeding (MB), acute myocardial infarction (AMI), and heart failure (HF) was assessed by competing risk analysis. Results: A total of 61.1%, 22.0%, and 16.9% were classified as low, moderate and high risk of liver fibrosis according to FIB-4 index, respectively. During a mean follow-up of 4.5 ± 1.7 years, FIB-4 index was associated with mortality (adjusted HR 1.04; 95% CI 1.01–1.06; p = 0.002), MB and HF (adjusted sHR 1.03, 95% CI 1.01–1.04; p = 0.004), but not with IS or with AMI. The association between FIB-4 and MB was only found in patients treated with vitamin K antagonists, not in patients on direct oral anticoagulants. Conclusions: The FIB-4 index, a non-invasive scoring method for evaluating liver fibrosis, is independently associated with all-cause mortality, MB and HF in patients with AF, suggesting that it may be useful as a risk assessment tool to identify adverse outcomes in patients with AF.

- Abstract
Background: Atrial fibrillation (AF) is an irregular heart rhythm which is becoming more and more common in this new era. Obesity is a risk factor for cardiovascular events, and obese patients are more at risk for stroke. The Framingham Heart Study demonstrated an increase in the developmental risk of AF by 4% for every unit (kg/m
2 ) increase in body mass index (BMI). An anticoagulant is often required for the management of such patients. In this analysis, we aimed to systematically compare the clinical outcomes which were associated with rivaroxaban versus warfarin for the treatment of obese patients with non-valvular AF. Methods: PubMed, EMBASE, Web of Science, http://www.ClinicalTrials.gov, Google Scholar, and Cochrane Central were the searched databases. Clinical outcomes including stroke, systemic embolism, and major bleeding were the endpoints. In this study, dichotomous data were analyzed by the RevMan software version 5.4. Risk ratio (RR) with 95% confidence interval (CI) was used for result interpretation. Results: Ten studies consisting of a total number of 168,081 obese participants were included whereby 81,332 participants were treated with rivaroxaban and 86,749 participants were treated with warfarin. The risks of ischemic (RR: 0.79, 95% CI: 0.74–0.84; P = 0.00001) and hemorrhagic stroke (RR: 0.61, 95% CI: 0.48–0.76; P = 0.0001) as well as systemic embolism (RR: 0.73, 95% CI: 0.62–0.87; P = 0.0004) were significantly lower with rivaroxaban compared to warfarin for the management of these obese patients with non-valvular AF. Rivaroxaban was also associated with a significantly lower risk of major bleeding (RR: 0.75, 95% CI: 0.65–0.87; P = 0.0001). Conclusion: Based on this analysis, rivaroxaban seemed to be a better option in comparison to warfarin, due to its association with significantly lower risks of stroke and bleeding outcomes in obese patients with non-valvular AF. However, this hypothesis should further be confirmed in larger clinical trials. [ABSTRACT FROM AUTHOR]- Published

• During the first 14 days of Direct oral anticoagulant (DOAC) therapy, a slight increase in serum levels of tacrolimus and cyclosporine can be found; • Serum Levels and concentration/dose ratio of Tacrolimus and cyclosporin were stable at 18 months follow-up in patients treated with DOAC; • DOACS have a similar safety and efficacy profile when compared to antagonist of vitamin K and no difference in terms of bleeding, thromboembolic events and renal function decline was found. direct oral anticoagulants (DOACs) are an alternative to conventional antagonist of vitamin-K (AVK). However, immune suppressive drugs (ISDs) may interfere with DOACs pharmacokinetic. evaluate safety and efficacy profile of DOACs compared to AVK in kidney transplant recipients (KTRs) treated with ISDs. a multi-center study from 4 Italian University hospitals enrolling consecutive KTRs on DOACs or AVK was carried out. Sixty-six patients on DOACs were compared with fifty patients on AVK with similar clinical features. Serial evaluation of renal function and serum levels of ISDs during 18 months follow-up (FU) was performed. Mean age of DOACs patients was 67±9 and mean eGFR was 58,3± 30,4mL/min/1.73m2. ISDs included tacrolimus (n=47, 71%), cyclosporin (n=13, 20%), everolimus (n=10, 7%) and sirolimus (n=4, 6%). After 14 days of DOACs therapy initiation there was a slight increase of serum levels of tacrolimus (+0.19±0.67 p=0.80) and cyclosporine (+0.12±0.25 p=0.94) not statistically significant. Levels of Tacrolimus and cyclosporin were stable at serial evaluation during 18-months follow-up. There were no thromboembolic events among patients treated with DOACs or AVK and no differences in term of major bleeding (6% vs 4% p=0.69), at long-term follow-up. There was no difference in term of eGFR decline from start therapy to 18 months FU between DOACs vs AVK therapy (-3.9±1 vs -3.8±2 p=0.82). DOACs have similar safety and efficacy than AVK among KTRs treated with ISDs. However, careful evaluation of potential drug interaction and ISDs serum levels is needed.

Background: Age is a major risk factor for venous thromboembolism (VTE), yet patients aged ≥90 years are under‐represented in clinical trials of anticoagulant therapy. The objectives were to describe and compare patient clinical characteristics, treatments, and outcomes (VTE recurrence, bleeding, and mortality) during the first 3 months of anticoagulation between VTE patients aged ≥90 years and those aged <90 years. Methods: We analyzed data from the Registro Informatizado Enfermedad TromboEmbὀlica (RIETE), an ongoing global observational registry of patients with objectively confirmed acute VTE. Results: From January 2001 to October 2022, 96,701 patients were registered in RIETE, of whom 3262 (3.4%) were aged ≥90 years. Patients aged ≥90 years were less likely to be men, and to have experienced cancer or recent surgery, but more likely to manifest immobility, chronic heart failure, anemia, renal insufficiency, or dementia than those aged <90 years. Most (99.6%) patients aged ≥90 years were receiving anticoagulant therapy. During the first 3 months, 26 patients aged ≥90 years developed VTE recurrences, 116 experienced major bleeding, and 564 died. Among patients initially presenting with pulmonary embolism (PE), deaths due to PE exceeded those due to fatal bleeding (76 vs. 19). Among those initially presenting with isolated deep‐vein thrombosis (DVT), it was the reverse (2 vs. 11 deaths). Conclusions: In patients aged ≥90 years, the difference in the outcome of anticoagulant treatment depending on the initial presentation of VTE could suggest a need for different management approaches. Clinical trials evaluating the optimal duration of anticoagulation according to initial VTE presentation are warranted to limit excess deaths in this particular population. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: Aortic stenosis is the most common valvular heart disease requiring surgical treatment. Minimally invasive surgical techniques have emerged as alternatives to traditional median sternotomy. Objective: To analyze the possible risk factors associated with major bleeding in patients undergoing aortic valve replacement via right anterior mini-thoracotomy and to share the results found in our center. Materials and methods: A retrospective, observational, longitudinal study was conducted in patients undergoing right anterior mini-thoracotomy from July 2015 to December 2022. Demographic and clinical data, as well as relevant surgical and echocardiographic variables, were collected. Results: The mean age of the study population had a mean age of 58 years, with a predominance of men under 65 years of age. Only three patients experienced major bleeding 4.47%. Advanced age and extracorporeal circulation time (minutes) were associated with bleeding. No significant differences were found in other variables analyzed. Conclusions: The study results indicate a low rate of postoperative bleeding in minimally invasive surgery. Advanced age and prolonged extracorporeal circulation time were identified as significant risk factors for major bleeding. However, further studies with a larger sample size are needed to better understand these factors and the safety of minimally invasive surgery. [ABSTRACT FROM AUTHOR]

(1) Background: The clinical management of anticoagulated patients treated with direct oral anticoagulants (DOAC) or Vitamin K antagonists (VKA) needing emergency surgery is challenging. (2) Methods: The prospective German RADOA registry investigated treatment strategies in DOAC- or VKA-treated patients needing emergency surgery within 24 h after admission. Effectiveness was analysed by clinical endpoints including major bleeding. Primary observation endpoint was in hospital mortality until 30 days after admission. (3) Results: A total of 78 patients were included (DOAC: 44; VKA: 34). Median age was 76 years. Overall, 43% of the DOAC patients and 79% of the VKA patients were treated with prothrombin complex concentrates (PCC) (p = 0.002). Out of the DOAC patients, 30% received no hemostatic treatment compared to 3% (1/34) of the VKA patients (p = 0.002), and 7% of the DOAC patients and 21% of the VKA patients developed major or clinically relevant non-major bleeding at the surgical site (p = 0.093). In-hospital mortality was 13% with no significant difference between the two treatment groups (DOAC: 11%, VKA: 15%; p > 0.20). (4) Conclusions: The 30-day in-hospital mortality rate was comparable between both patient groups. VKA patients required significantly more hemostatic agents than DOAC patients in the peri- and postoperative surgery period. [ABSTRACT FROM AUTHOR]

BACKGROUND: The traditional definition of massive transfusion is 10 red blood cell units transfused within 24 hr. This definition has been faulted for excluding patients who die early from exsanguination. Alternative major bleeding definitions in the trauma literature include time-based (e.g., Resuscitation Intensity) and event based (e.g., Sharpe) transfusion thresholds. OBJECTIVE: The study objective was to compare four definitions of major bleeding, including a modification to the Sharpe definition, on clinically relevant processes and outcomes. METHODS: This is a retrospective cohort study of adult trauma patients admitted from the field to a Level I trauma center from 2014 to 2019. Data sources were the trauma registry, blood bank, and electronic medical records. Transfusion thresholds were defined as follows: Resuscitation Intensity--4 units of any combination of crystalloids, colloids, or blood products within the first 30 min of arrival; Sharpe--10 red blood cell units from trauma bay presentation to inpatient admission (a proxy for the interval of hemorrhage control); Modified Sharpe--10 units of any combination of blood products during the same interval. The study analysis consisted of descriptive statistics. RESULTS: The cohort contained 187 subjects. Of 39 deaths, 28 (72%) occurred within 6 hr following arrival. Modified Sharpe captured 27 (96%) of these 28 subjects, whereas Resuscitation Intensity captured 20 (71%). Sharpe and the traditional definition each captured 22 subjects (79%). Modified Sharpe captured 17%-25% of deaths missed by the other definitions. CONCLUSION: Modified Sharpe may optimally indicate major bleeding during trauma resuscitation. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: Oral anticoagulants effectively prevent stroke/systemic embolism among patients with non-valvular atrial fibrillation but remain under-prescribed. This study evaluated temporal trends in oral anticoagulant use, the incidence of stroke/systemic embolism and major bleeding, and economic outcomes among elderly patients with non-valvular atrial fibrillation and CHA
2 DS2 –VASc scores ≥ 2. Methods: Retrospective analyses were conducted on Medicare claims data from January 1, 2012 through December 31, 2017. Non-valvular atrial fibrillation patients aged ≥ 65 years with CHA2 DS2 –VASc scores ≥ 2 were stratified by calendar year (2013–2016) of care to create calendar-year cohorts. Patient characteristics were evaluated across all cohorts during the baseline period (12 months before diagnosis). Treatment patterns and clinical and economic outcomes were evaluated during the follow-up period (from diagnosis through 12 months). Results: Baseline patient characteristics remained generally similar between 2013 and 2016. Although lack of oral anticoagulant prescriptions among eligible patients remained relatively high, utilization did increase progressively (53–58%). Among treated patients, there was a progressive decrease in warfarin use (79–52%) and a progressive increase in overall direct oral anticoagulant use (21–48%). There were progressive decreases in the incidence of stroke/systemic embolism 1.9–1.4 events per 100 person years) and major bleeding (4.6–3.3 events per 100 person years) as well as all-cause costs between 2013 and 2016. Conclusions: The proportions of patients with non-valvular atrial fibrillation who were not prescribed an oral anticoagulant decreased but remained high. We observed an increase in direct oral anticoagulant use that coincided with decreased incidence of clinical outcomes as well as decreasing total healthcare costs. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Introduction: Venous thromboembolism (VTE) consists of deep vein thrombosis (DVT) and pulmonary embolism (PE). Rivaroxaban is a direct oral anticoagulant (DOAC) inhibiting activated coagulation factor X (FXa), and exerts several advantages in the treatment of VTE compared to conventional therapy. However, the efficacy and safety of rivaroxaban in elderly patients with VTE was still poorly understood. Methods: The study was carried out using an observational and non-interventional approach. A total of 576 patients aged ≥ 60 years with newly diagnosed VTE were included in the study. All patients received rivaroxaban with recommended treatment duration of ≥ 3 months for secondary prevention. In addition, 535 elderly patients with various diseases except VTE were included in the study in a retrospective and randomized way. Results: The total bleeding rate was 12.2% (70/576). Major bleeding and non-major clinically relevant (NMCR) bleeding occurred in 4 (0.69%) patients and 5 (0.87%) patients, respectively. The rate of recurrent VTE was 5.4%. The mean level of D-dimers was increased by 467.2% in the elderly patients with VTE compared with the elderly patients without VTE. The elderly patients with VTE receiving rivaroxaban at a dose of 10 mg once daily (n = 134) had lower risk for bleeding (3.7% vs 14.7%; P = 0.001) and a similar rate of recurrent VTE (4.5% vs 5.7%; P = 0.596) as compared to the elderly patients with VTE receiving rivaroxaban at higher doses including 15 mg once daily and 20 mg once daily (n = 442). In addition, age, concomitant aspirin, hemoglobin, activated partial thromboplastin time (APTT), and rivaroxaban doses were independent predictive factors for bleeding events. Conclusions: The study suggested that a dose of 10 mg once daily should be the priority in elderly patients with VTE receiving long-term rivaroxaban anticoagulation therapy in view of reduced bleeding risk.

Introduction: Oral anticoagulant therapy comes at the cost of a significant bleeding risk. However, it is hard to predict which patients are at risk of major bleeding. Previously we found associations of Calibrated Automated Thrombinography (CAT) parameters obtained in the presence of TIX-5 (an inhibitor of the FV activation by FXa), and plasma levels of TFPIα, γ’-fibrinogen and soluble thrombomodulin with major bleeding in the BLEEDS cohort, a cohort especially powered to find new biomarkers of major bleeding during VKA therapy. Methods: To determine and compare the predictive capability for major bleeding in the BLEEDS cohort of the above biomarkers, also in a combined model with clinical risk factors, we performed Univariable Prentice-weighted Cox regression analyses and Bayesian variable selection. Results: The highest predictive value among the laboratory measures were found for thrombin generation lagtime in the presence of TIX-5 (TIX-5 lagtime per 25% increase, hazard ratio (HR) 1.11, 95%CI 1.04–1.18, p=0.001) and full-length tissue factor pathway inhibitor (TFPIα) (per 25% increase HR 1.12, 95%CI 1.03–1.21, p=0.008), which remained significant after correction for multiple testing, and independently associated with major bleeding after Bayesian variable selection. Only the addition of TIX-5 lagtime to the clinical risk factors improved prediction of major bleeding significantly (p

Abstract Background Randomized clinical trials in non-critically ill COVID-19 patients showed that therapeutic-dose heparin increased survival with reduced organ support as compared with usual-care thromboprophylaxis, albeit with increased bleeding risk. The purpose of the study is to assess the safety of intermediate dose enoxaparin in hospitalized patients with moderate to severe COVID-19. Methods A phase II single-arm interventional prospective study including patients receiving intermediate dose enoxaparin once daily according to body weight: 60 mg for 45–60 kg, 80 mg for 61–100 kg or 100 mg for > 100 kg for 14 days, with dose adjustment according to anti-factor Xa activity (target range: 0.4–0.6 UI/ml); an observational cohort (OC) included patients receiving enoxaparin 40 mg day for comparison. Follow-up was 90 days. Primary outcome was major bleeding within 30 and 90 days after treatment onset. Secondary outcome was the composite of all-cause 30 and 90-day mortality rates, disease severity at the end of treatment, intensive care unit (ICU) admission and length of ICU stay, length of hospitalization. All outcomes were adjudicated by an independent committee and analyzed before and after propensity score matching (PSm). Results Major bleeding was similar in IC (1/98 1.02%) and in the OC (none), with only one event observed in a patient receiving concomitantly anti-platelet therapy. The composite outcome was observed in 53/98 patients (54%) in the IC and 132/203 (65%) patients in the OC (p = 0.07) before PSm, while it was observed in 50/90 patients (55.6%) in the IC and in 56/90 patients (62.2%) in the OC after PSm (p = 0.45). Length of hospitalization was lower in the IC than in OC [median 13 (IQR 8–16) vs 14 (11–21) days, p = 0.001], however it lost statistical significance after PSm (p = 0.08). At 30 days, two patients had venous thrombosis and two pulmonary embolism in the OC. Time to first negative RT-PCR were similar in the two groups. Conclusions Weight adjusted intermediate dose heparin with anti-FXa monitoring is safe with potential positive impact on clinical course in COVID-19 non-critically ill patients. Trial registration The study INHIXACOVID19 was registred on ClinicalTrials.gov with the trial registration number (TRN) NCT04427098 on 11/06/2020.

Aims: Our aims were to describe the clinical characteristics, adverse clinical events, healthcare resource utilization (HCRU) and costs of patients with major bleeding during direct Factor Xa inhibitor (FXai) use. Methods: This is a retrospective cohort study that included secondary data from computerized health records of seven Spanish Autonomous Communities. Patients with a first major bleeding during treatment with a direct FXai were analyzed during a 3-year period. Results: Of 8972 patients taking a direct FXai, 470 (5.24%) had major bleeding (mean age (SD) 77.93 (9.71) years, 61.06% women). The most frequent indications for using FXais were atrial fibrillation (78.09%) and venous thromboembolism (17.66%). Among those with major bleeding, 88.94% presented with gastrointestinal bleeding, 6.81% intracranial bleeding, 2.13% trauma-related bleeding and 4.26% other major bleeding. Prothrombin complex concentrates were used in 63.19%, followed by transfusion of blood products (20.21%) and Factor VIIa (7.66%). In total, 4.26% of patients died in the hospital due to the first major bleeding. At the study end (after 3-year follow-up), 28.94% of the patients had died, 12.34% had a myocardial infarction and 9.15% an ischemic stroke. At year 3, overall bleeding cost was EUR 5,816,930.5, of which 79.74% accounted for in-hospital costs to treat the bleeding episode. Conclusions: Despite the use of replacement agents being high, major events were common, with a 29% mortality at the end of the follow up, and HCRU and costs were high, evidencing the need for new reversal treatment strategies.

- Abstract
Aim: Fondaparinux is a synthetic anticoagulant that inhibits thrombosis by suppressing factor Xa. The efficacy of fondaparinux for orthopedic surgeries has been revealed by several foreign studies; however, relevant evidence in Chinese patients is lacking. This study intended to investigate the occurrence rate and risk factors of in-hospital venous thromboembolism (VTE), major bleeding, and death in patients receiving fondaparinux after orthopedic surgery or trauma surgery. Methods: Totally, 1258 patients who received fondaparinux after orthopedic surgery or trauma surgery were retrospectively enrolled. Meanwhile, in-hospital VTE, major bleeding, and death were obtained for assessment. Besides, adverse events were recorded. Results: The occurrence rates of in-hospital VTE, major bleeding, and death were 2.5%, 21.8%, and 0.0%, respectively. The multivariate logistic regression analysis revealed that only age (> 60 years vs. ≤ 60 years) (odd ratios (OR) = 3.380, P = 0.013) was independently correlated with increased risk of in-hospital VTE. Additionally, osteoarthritis diagnosis (OR = 3.826, P < 0.001), femoral head necrosis diagnosis (OR = 1.809, P = 0.034), hip replacement (vs. internal fracture fixation) (OR = 2.199, P = 0.007), knee replacement (vs. internal fracture fixation) (OR = 2.781, P = 0.002), and serum creatinine (abnormal vs. normal) (OR = 1.677, P = 0.012) were independently linked to a higher risk of in-hospital major bleeding. Moreover, the common adverse events included pain (56.6%), wound bleeding (23.0%), increased drainage (5.2%), etc. Conclusion: Fondaparinux realizes low occurrence rates of in-hospital VTE and major bleeding with tolerable adverse events in patients receiving orthopedic surgery or trauma surgery.

Background: Little is known about anticoagulation medication nonadherence patterns impacting effectiveness and safety outcomes in clinical practice. Objective: We identified adherence trajectories of extended therapy with direct-acting oral anticoagulants (DOACs) and warfarin after 6 months initial anticoagulant therapy among Medicare beneficiaries with venous thromboembolism (VTE). We further assessed the associated recurrent VTE and major bleeding risks. Methods: Using group-based trajectory models, this retrospective cohort study identified distinct beneficiary subgroups with similar adherence patterns of extended-phase anticoagulant treatment (DOACs or warfarin) for patients with VTE who completed 6 months of initial anticoagulant treatment. We examined associations between adherence trajectories and risks of recurrent VTE and major bleeding using inverse probability treatment weighted Cox proportional hazards models. Results: Compared with no extended treatment, consistently high DOAC adherence was associated with decreased recurrent VTE risk (hazard ratio [HR] = 0.33, 95% confidence interval [CI] = 0.21-0.51) without increased major bleeding risk, and consistently high warfarin adherence was associated with decreased recurrent VTE risk (HR = 0.62, 95% CI = 0.40-0.95) and increased major bleeding risk (HR = 1.64, 95% CI = 1.12-2.41). Gradually declining adherence to DOACs (HR = 1.80, 95% CI = 1.07-3.03) or warfarin (HR = 2.34, 95% CI = 1.57-3.47) was associated with increased bleeding risk with no change in recurrent VTE risk. Conclusion and relevance: This real-world evidence suggests persistently adhering to extended DOAC therapy is associated with lower recurrent VTE risk without increasing major bleeding among Medicare beneficiaries with VTE. Persistently adhering to extended warfarin therapy was associated with lower recurrent VTE risk but higher major bleeding risk. [ABSTRACT FROM AUTHOR]

Background: Patients with gastrointestinal cancer (GICA) are at high risk for venous thromboembolism (VTE). Data from randomized clinical trials in cancer-associated VTE suggest that direct oral anticoagulants (DOACs) conferred similar or superior efficacy but a heterogeneous safety profile in patients with GICA. We compared the safety and effectiveness of DOACs in patients with GICA and VTE at MD Anderson Cancer Center. Materials and Methods: This was a retrospective chart review of patients with GICA and VTE receiving treatment with DOACs for a minimum of 6 months. Primary outcomes were the proportion of patients experiencing major bleeding (MB), clinically relevant non-major bleeding (CRNMB), and recurrent VTE. Secondary outcomes were time to bleeding and recurrent VTE. Results: A cohort of 433 patients with GICA who were prescribed apixaban (n = 300), or rivaroxaban (n = 133) were included. MB occurred in 3.7% (95% confidence interval [CI] 2.1-5.9), CRNMB in 5.3% (95% CI 3.4-7.9), and recurrent VTE in 7.4% (95% CI 5.1-10.3). The cumulative incidence rates of CRNMB and recurrent VTE were not significantly different when comparing apixaban to rivaroxaban. Conclusion: Apixaban and rivaroxaban had a similar risk of recurrent VTE and bleeding and could be considered as anticoagulant options in selected patients with GICA and VTE. Patients with cancer are at increased risk for venous thromboembolism. This article evaluates the safety and effectiveness of direct oral anticoagulants in patients with gastrointestinal cancer and cancer-associated venous thromboembolism. [ABSTRACT FROM AUTHOR]

INTRA-aortic balloon counterpulsation , *CARDIOGENIC shock , *PERCUTANEOUS coronary intervention , *ARTIFICIAL blood circulation - Abstract
To assess the clinical characteristics and in-hospital bleeding complications and major adverse cardiac and cerebrovascular events (MACCE) associated with the use of Impella alone or the combination of an intra-aortic balloon pump (IABP) with Impella in cardiogenic shock (CS) patients undergoing percutaneous coronary intervention (PCI). All CS patients who underwent PCI and were treated with an Impella mechanical circulatory support (MCS) device were identified. Patients were divided into two groups: having MCS support with Impella alone or with both, IABP and Impella simultaneously (dual MCS group). Bleeding complications were classified by a modified Bleeding Academic Research Consortium (BARC) classification. Major bleeding was defined as BARC≥3 bleeding. MACCE was the composite of in-hospital death, myocardial infarction, cerebrovascular events and major bleeding complications. Between 2010 and 2018 a total of 101 patients were treated at six tertiary care New York hospitals with either Impella (n = 61) or dual MCS with Impella and IABP (n = 40). Clinical characteristics were similar for both groups. Dual MCS patients presented more often with a STEMI (77.5 % vs. 45.9 %, p = 0.002) and had left main coronary artery intervention (20.3 % vs. 8.6 %, p = 0.03). Major bleeding complications (69.4 % vs. 74.1 %, p = 0.62) and MACCE rates (80.6 % vs. 79.3 %, p = 0.88) were very high but similar in both groups, however access site bleeding complications were lower in patients treated with dual MCS. In-hospital mortality was 29.5 % for the Impella group and 25.0 % for the dual MCS group (p = 062). Access site bleeding complications were lower in in patients treated with dual MCS (5.0 % vs. 24.6 %, p = 0.01). In CS patients undergoing PCI with either the Impella device alone or with Impella and IABP, major bleeding complications and MACCE rates were high but not significantly different between the two groups. In hospital mortality was relatively low in both MCS groups despite the high-risk characteristics of these patients. Future studies should assess the risks and benefits of the simultaneous use of these two MCS in CS patients undergoing PCI. • A total of 101 cardiogenic shock patients were treated with either Impella (n =61) or with Impella plus IABP (n =40). • Clinical characteristics were similar in both groups. • Patients treated simultaneously with both devices presented more often with a STEMI and had left main coronary artery intervention. • Major bleeding complications (69.4% vs. 74.1%, p =0.62) and MACCE rates (80.6% vs. 79.3%, p =0.88) were very high but similar in both groups. • In-hospital mortality was 29.5% for the Impella group and 25.0% for the dual group (p =062). Access site bleeding complications were lower in in patients treated with dual MCS (5.0 % vs. 24.6 %, p = 0.01). [ABSTRACT FROM AUTHOR]

- Abstract
Aims Limited real-world data show that rivaroxaban following dosage criteria from either ROCKET AF [20 mg/day or 15 mg/day if creatinine clearance (CrCl) < 50 mL/min] or J-ROCKET AF (15 mg/day or 10 mg/day if CrCl < 50 mL/min) is associated with comparable risks of thromboembolism and bleeding with each other in patients with non-valvular atrial fibrillation (NVAF). We are aimed to study whether these observations differ between Asian and non-Asian subjects. Methods and results A systematic review and meta-analysis with random effects was conducted to estimate the aggregate hazard ratio (HR) and 95% confidence interval (CI) using PubMed and MEDLINE databases from 8 September 2011 to 31 December 2022 searched for adjusted observational studies that reported relevant clinical outcomes of NVAF patients receiving rivaroxaban 10 mg/day if CrCl > 50 mL/min, on-label dose rivaroxaban eligible for ROCKET AF or J-ROCKET AF, and rivaroxaban 20 mg/day if CrCl < 50 mL/min. Effectiveness and safety endpoints were compared between ROCKET AF and J-ROCKET AF dosing regimen in Asian and non-Asian subjects, separately. Also, risks of events of rivaroxaban 10 mg/day despite of CrCl > 50 mL/min and rivaroxaban 20 mg/day despite of CrCl < 50 mL/min were compared to that of 'ROCKET AF/J-ROCKET AF dosing'. Sensitivity analyses were performed by sequential elimination of each study from the pool. The meta-regression analysis was performed to explore the influence of potential factors on the effectiveness and safety outcomes. Eighteen studies involving 67 571 Asian and 54 882 non-Asian patients were included. Rivaroxaban following J-ROCKET AF criteria was associated with comparable risks of thromboembolism in the Asian subgroup, whereas rivaroxaban following J-ROCKET AF criteria was associated with higher risks of all-cause mortality (HR:1.30; 95% CI:1.05–1.60) compared with that of ROCKET AF criteria in the non-Asian population. There were no differences in risks of major bleeding between rivaroxaban following J-ROCKET AF vs. ROCKET AF criteria either in the Asian or non-Asian population. The use of rivaroxaban 10 mg despite of CrCl > 50 mL/min was associated with a higher risk of thromboembolism (HR:1.64; 95% CI:1.28–2.11) but lower risk of major bleeding (HR:0.72; 95% CI:0.57–0.90) compared with eligible dosage criteria. The use of rivaroxaban 20 mg despite of CrCl < 50 mL/min was associated with worse clinical outcomes in the risks of thromboembolism (HR:1.32; 95% CI:1.09–1.59), mortality (HR:1.33; 95% CI:1.10–1.59), and major bleeding (HR:1.26; 95% CI:1.03–1.53) compared with eligible dosage criteria. The pooled results were generally in line with the primary effectiveness and safety outcomes by removing a single study at one time. Meta-regression analyses failed to detect the bias in most potential patient characteristics associated with the clinical outcomes. Conclusion Rivaroxaban dosing regimen following J-ROCKET criteria may serve as an alternative to ROCKET AF criteria for the Asian population with NVAF, whereas the dosing regimen following ROCKET AF criteria was more favourable for the non-Asian population. The use of rivaroxaban 10 mg despite of CrCl > 50 mL/min was associated with a higher risk of thromboembolism but a lower risk of major bleeding, while use of rivaroxaban 20 mg despite of CrCl < 50 mL/min was associated with worse outcome in most clinical events.

More than 1 million transcatheter-based cardiovascular procedures across the spectrum of interventional cardiology are performed annually in the United States. With the expanded indications for and increased complexities associated with these procedures, interventional cardiologists are expected to possess the requisite expertise to complete these interventions safely and effectively. While the art of vascular access and closure remains a prerequisite and critical skillset in contemporary practice, there remain significant variations in the techniques employed, resulting in the bleeding and vascular complications encountered in clinical practice. With an increasing recognition of the potential merits to standardized approaches to vascular access and closure, cardiovascular societies have put forth recommendations around best practices for performing these procedures in the cardiac catheterization laboratories. In this review, we aim to: (1) Examine the evolving definitions of bleeding and vascular complications; (2) Review best practices for transradial and transfemoral access and closure, including for large bore procedures; and (3) Highlight knowledge gaps and proposed areas of clinical research pertaining to vascular access which may inform clinical practice and potentially optimize the outcomes of patients undergoing transcatheter-based cardiac and vascular interventions.

Background Venous thromboembolism (VTE) in hospitalized medically ill patients is a significant cause of morbidity and mortality. Guidelines suggest that VTE and bleeding risk assessment models (RAMs) should be integrated into the clinical decision-making process on thromboprophylaxis. However, poor evidence is available comparing the use of a RAM versus clinical judgement in evaluating VTE and bleeding occurrence.
