BACKGROUND: Strokes after left atrial appendage closure (LAAC) prophylaxis are generally less severe than those after warfarin prophylaxis-thought to be secondary to more hemorrhagic strokes with warfarin. Hemorrhagic strokes are similarly infrequent with direct oral anticoagulant (DOAC) prophylaxis, so the primary subtype after either LAAC or DOAC prophylaxis is ischemic stroke (IS). OBJECTIVES: The purpose of this study was to compare the severity of IS using the modified Rankin Scale in atrial fibrillation patients receiving prophylaxis with DOACs vs LAAC. METHODS: A retrospective analysis was performed of consecutive patients undergoing LAAC at 8 centers who developed an IS (ISLAAC) compared with contemporaneous consecutive patients who developed IS during treatment with DOACs (ISDOAC). The primary outcome was disabling/fatal stroke (modified Rankin Scale 3-5) at discharge and 3 months later. RESULTS: Compared with ISDOAC patients (n = 322), ISLAAC patients (n = 125) were older (age 77.2 ± 13.4 years vs 73.1 ± 11.9 years; P = 0.002), with higher HAS-BLED scores (3.0 vs 2.0; P = 0.004) and more frequent prior bleeding events (54.4% vs 23.6%; P < 0.001), but similar CHA2DS2-VASc scores (5.0 vs 5.0; P = 0.28). Strokes were less frequently disabling/fatal with ISLAAC than ISDOAC at both hospital discharge (38.3% vs 70.3%; P < 0.001) and 3 months later (33.3% vs 56.2%; P < 0.001). Differences in stroke severity persisted after propensity score matching. By multivariate regression analysis, ISLAAC was independently associated with fewer disabling/fatal strokes at discharge (OR: 0.22; 95% CI: 0.13-0.39; P < 0.001) and 3 months (OR: 0.25; 95% CI: 0.12-0.50; P < 0.001), and fewer deaths at 3 months (OR: 0.28; 95% CI: 0.12-0.64; P < 0.001). CONCLUSIONS: Ischemic strokes in patients with atrial fibrillation are less often disabling or fatal with LAAC than DOAC prophylaxis.

BACKGROUND: Subclinical atrial fibrillation is short-lasting and asymptomatic and can usually be detected only by long-term continuous monitoring with pacemakers or defibrillators. Subclinical atrial fibrillation is associated with an increased risk of stroke by a factor of 2.5; however, treatment with oral anticoagulation is of uncertain benefit. METHODS: We conducted a trial involving patients with subclinical atrial fibrillation lasting 6 minutes to 24 hours. Patients were randomly assigned in a double-blind, double-dummy design to receive apixaban at a dose of 5 mg twice daily (2.5 mg twice daily when indicated) or aspirin at a dose of 81 mg daily. The trial medication was discontinued and anticoagulation started if subclinical atrial fibrillation lasting more than 24 hours or clinical atrial fibrillation developed. The primary efficacy outcome, stroke or systemic embolism, was assessed in the intention-to-treat population (all the patients who had undergone randomization); the primary safety outcome, major bleeding, was assessed in the on-treatment population (all the patients who had undergone randomization and received at least one dose of the assigned trial drug, with follow-up censored 5 days after permanent discontinuation of trial medication for any reason). RESULTS: We included 4012 patients with a mean (±SD) age of 76.8±7.6 years and a mean CHA2DS2-VASc score of 3.9±1.1 (scores range from 0 to 9, with higher scores indicating a higher risk of stroke); 36.1% of the patients were women. After a mean follow-up of 3.5±1.8 years, stroke or systemic embolism occurred in 55 patients in the apixaban group (0.78% per patient-year) and in 86 patients in the aspirin group (1.24% per patient-year) (hazard ratio, 0.63; 95% confidence interval [CI], 0.45 to 0.88; P = 0.007). In the on-treatment population, the rate of major bleeding was 1.71% per patient-year in the apixaban group and 0.94% per patient-year in the aspirin group (hazard ratio, 1.80; 95% CI, 1.26 to 2.57; P = 0.001). Fatal bleeding occurred in 5 patients in the apixaban group and 8 patients in the aspirin group. CONCLUSIONS: Among patients with subclinical atrial fibrillation, apixaban resulted in a lower risk of stroke or systemic embolism than aspirin but a higher risk of major bleeding.

Thrombosis and bleeding are commonly observed in cancer patients, and their management is crucial for positive patient outcomes. A comprehensive, prophylactic, and therapeutic management of venous thrombosis should focus on identifying the patients who would benefit most from treatment to reduce mortality and minimize the risk of thrombosis recurrence without significantly increasing the risk of bleeding. Existing cancer scales provide valuable information for assessing the overall burden of cancer and guiding treatment decisions, but their ability to predict thrombotic and bleeding events remains limited. With increasing knowledge of the pathophysiology of cancer and the availability of advanced anticancer therapies, new risk factors for cancer-associated thrombosis and bleeding are being identified. In this report, we analyze the current literature and identify new risk factors for venous thrombosis and bleeding which are not included in routinely used risk scores. While some existing cancer scales partially capture the risk of thrombosis and bleeding, there is a need for more specific and accurate scales tailored to these complications. The development of such scales could improve risk stratification, aid in treatment selection, and enhance patient care. Therefore, further research and development of novel cancer scales focused on thrombosis and bleeding are warranted to optimize patient management and outcomes.

Rationale: Definitive guidelines for anticoagulation management during veno-venous extracorporeal membrane oxygenation (VV ECMO) are lacking, whereas bleeding complications continue to pose major challenges. Objectives: To describe anticoagulation modalities and bleeding events in adults receiving VV ECMO. Methods: This was an international prospective observational study in 41 centers, from December 2018 to February 2021. Anticoagulation was recorded daily in terms of type, dosage, and monitoring strategy. Bleeding events were reported according to site, severity, and impact on mortality. Measurements and Main Results: The study cohort included 652 patients, and 8,471 days on ECMO were analyzed. Unfractionated heparin was the initial anticoagulant in 77% of patients, and the most frequently used anticoagulant during the ECMO course (6,221 d; 73%). Activated partial thromboplastin time (aPTT) was the most common test for monitoring coagulation (86% of days): the median value was 52 seconds (interquartile range, 39 to 61 s) but dropped by 5.3 seconds after the first bleeding event (95% confidence interval, -7.4 to -3.2; P < 0.01). Bleeding occurred on 1,202 days (16.5%). Overall, 342 patients (52.5%) experienced at least one bleeding event (one episode every 215 h on ECMO), of which 10 (1.6%) were fatal. In a multiple penalized Cox proportional hazard model, higher aPTT was a potentially modifiable risk factor for the first episode of bleeding (for 20-s increase; hazard ratio, 1.07). Conclusions: Anticoagulation during VV ECMO was a dynamic process, with frequent stopping in cases of bleeding and restart according to the clinical picture. Future studies might explore lower aPTT targets to reduce the risk of bleeding.

Inhibitory Brutonovy kinázy (BTKi) jsou první skupinou cílených léčiv, která výrazně zlepšila prognózu i kvalitu života nemocných s chronickou lymfocytární leukemií (CLL). Specifické nežádoucí účinky BTKi, zejména kardiovaskulární (KV) a krvácivé, však mohou limitovat jejich dlouhodobé užívání. Ibrutinib, BTKi první generace, byl pro nežádoucí účinky přerušen až u 26 % pacientů léčených v rámci klinických studií. I z těchto důvodů pokračují snahy o vývoj dalších generací BTKi, které by měly bezpečnější profil při zachovaném protinádorovém účinku. Patří mezi ně kovalentně se vázající BTKi akalabrutinib a zanubrutinib a reverzibilní, nekovalentní BTK inhibitory pirtobrutinib a nemtabrutinib. V České republice je v současnosti z veřejného zdravotního pojištění hrazen akalabrutinib. V rámci prevence KV komplikací je zásadní stanovení KV rizika u konkrétního pacienta; pro tyto potřeby lze využít jednoduché skórovací systémy typu Framinghamského skóre nebo tabulky SCORE. U nemocných s vysokým KV rizikem je doporučována léčba BTKi 2. generace nebo léky ze skupiny bcl-2 inhibitorů, případně inhibitorů fosfatidylinositol-3-kinázy. Pokud dojde k rozvoji fibrilace síní nebo srdečního selhání, je nezbytná spolupráce s kardiologem. Riziko závažného krvácení je, na rozdíl od KV komplikací, podobné u obou dostupných preparátů (2–9 % u ibrutinibu vs. 2–5 % u akalabrutinibu). V prevenci klinicky manifestního krvácení je zásadní přerušení léčby BTKi s dostatečným předstihem před každým invazivním výkonem a znovuzahájení terapie až ve chvíli, kdy je riziko krvácení již minimální. Důležitým faktorem pro snížení rizika rozvoje jakékoli komplikace je znalost stávající medikace pacienta a potenciálních lékových interakcí s BTKi. Tato práce shrnuje mechanizmus vniku kardiovaskulárních a krvácivých komplikací, jejich incidenci ve vybraných klinických studiích a doporučení pro prevenci a léčbu těchto nežádoucích účinků v běžné klinické praxi.

Bruton’s tyrosine kinase (BTK) inhibitors have altered the treatment landscape of chronic lymphocytic leukaemia (CLL). These highly eff ective drugs improve not only the prognosis but also the quality of life of CLL patients. Long-term BTK inhibitor treatment can be limited by specifi c adverse events (AEs) such as cardiovascular (CV) complications or bleeding. Ibrutinib, the fi rst-in-class BTK inhibitor, was discontinued in up to 26% of patients in clinical trials due to AEs. Therefore, there are continuing eff orts to develop BTK inhibitors with the same eff ectivity but better safety profi le, such as covalent BTKi acalabrutinib and zanubrutinib and non-covalent BTKi pirtobrutinib and nemtabrutinib. The pre-treatment workup for all patients should include CV risk level assessment using scoring systems, e. g., Framingham risk score or SCORE. In patients with high CV risk levels, next-generation BTK inhibitors or other targeted drugs (venetoclax or idelalisib) are generally preferred over ibrutinib. Patients who experience CV toxicity, particularly atrial fi brillation or heart failure, should be consulted with a cardiologist to defi ne the best treatment algorithm. In contrast to CV toxicity, the risk of major bleeding events is equal for both ibrutinib and acalabrutinib (2–9% vs. 2–5%) based on data from clinical trials. Regarding prevention of bleeding events, BTK inhibitor treatment should be appropriately held prior to any invasive procedure and cannot be restarted until the risk of bleeding is minimal. Good knowledge of the patient’s current medication and potential interactions is crucial in the prevention of any adverse event. This review describes the mechanisms of pathogenesis of cardiovascular complications and bleeding in BTK inhibitor-treated patients. It summarises their incidence in selected clinical trials and provides recommendations for managing these AEs in clinical practice.

BACKGROUND: Device-detected atrial high-rate episodes (AHREs) are atrial arrhythmias detected by implanted cardiac devices. AHREs resemble atrial fibrillation but are rare and brief. Whether the occurrence of AHREs in patients without atrial fibrillation (as documented on a conventional electrocardiogram [ECG]) justifies the initiation of anticoagulants is not known. METHODS: We conducted an event-driven, double-blind, double-dummy, randomized trial involving patients 65 years of age or older who had AHREs lasting for at least 6 minutes and who had at least one additional risk factor for stroke. Patients were randomly assigned in a 1:1 ratio to receive edoxaban or placebo. The primary efficacy outcome was a composite of cardiovascular death, stroke, or systemic embolism, evaluated in a time-to-event analysis. The safety outcome was a composite of death from any cause or major bleeding. RESULTS: The analysis population consisted of 2536 patients (1270 in the edoxaban group and 1266 in the placebo group). The mean age was 78 years, 37.4% were women, and the median duration of AHREs was 2.8 hours. The trial was terminated early, at a median follow-up of 21 months, on the basis of safety concerns and the results of an independent, informal assessment of futility for the efficacy of edoxaban; at termination, the planned enrollment had been completed. A primary efficacy outcome event occurred in 83 patients (3.2% per patient-year) in the edoxaban group and in 101 patients (4.0% per patient-year) in the placebo group (hazard ratio, 0.81; 95% confidence interval [CI], 0.60 to 1.08; P = 0.15). The incidence of stroke was approximately 1% per patient-year in both groups. A safety outcome event occurred in 149 patients (5.9% per patient-year) in the edoxaban group and in 114 patients (4.5% per patient-year) in the placebo group (hazard ratio, 1.31; 95% CI, 1.02 to 1.67; P = 0.03). ECG-diagnosed atrial fibrillation developed in 462 of 2536 patients (18.2% total, 8.7% per patient-year). CONCLUSIONS: Among patients with AHREs detected by implantable devices, anticoagulation with edoxaban did not significantly reduce the incidence of a composite of cardiovascular death, stroke, or systemic embolism as compared with placebo, but it led to a higher incidence of a composite of death or major bleeding. The incidence of stroke was low in both groups.

BACKGROUND: Recent data have suggested that insulin-requiring diabetes mostly contributes to the overall increase of thromboembolic risk in patients with atrial fibrillation (AF) on warfarin. We evaluated the prognostic role of a different diabetes status on clinical outcome in a large cohort of AF patients treated with edoxaban. METHODS: We accessed individual patients' data from the prospective, multicenter, ETNA-AF Europe Registry. We compared the rates of ischemic stroke/transient ischemic attack (TIA)/systemic embolism, myocardial infarction (MI), major bleeding and all-cause death at 2 years according to diabetes status. RESULTS: Out of an overall population of 13,133 patients, 2885 had diabetes (22.0%), 605 of whom (21.0%) were on insulin. The yearly incidence of ischemic stroke/TIA/systemic embolism was 0.86% in patients without diabetes, 0.87% in diabetic patients not receiving insulin (p = 0.92 vs no diabetes) and 1.81% in those on insulin (p = 0.002 vs no diabetes; p = 0.014 vs diabetes not on insulin). The annual rates of MI and major bleeding were 0.40%, 0.43%, 1.04% and 0.90%, 1.10% and 1.71%, respectively. All-cause yearly mortality was 3.36%, 5.02% and 8.91%. At multivariate analysis, diabetes on insulin was associated with a higher rate of ischemic stroke/TIA/systemic embolism [adjusted HR 2.20, 95% CI 1.37-3.54, p = 0.0011 vs no diabetes + diabetes not on insulin] and all-cause death [aHR 2.13 (95% CI 1.68-2.68, p < 0.0001 vs no diabetes]. Diabetic patients not on insulin had a higher mortality [aHR 1.32 (1.11-1.57), p = 0.0015], but similar incidence of stroke/TIA/systemic embolism, MI and major bleeding, vs those without diabetes. CONCLUSIONS: In a real-world cohort of AF patients on edoxaban, diabetes requiring insulin therapy, rather than the presence of diabetes per se, appears to be an independent factor affecting the occurrence of thromboembolic events during follow-up. Regardless of the diabetes type, diabetic patients had a lower survival compared with those without diabetes.

INTRODUCTION: Observational studies have shown low bleeding rates in patients with atrial fibrillation (AF) treated by left atrial appendage closure (LAAC); however, data from randomized studies are lacking. This study compared bleeding events among patients with AF treated by LAAC and nonvitamin K anticoagulants (NOAC). METHODS: The Prague-17 trial was a prospective, multicenter, randomized trial that compared LAAC to NOAC in high-risk AF patients. The primary endpoint was a composite of a cardioembolic event, cardiovascular death, and major and clinically relevant nonmajor bleeding (CRNMB) defined according to the International Society on Thrombosis and Hemostasis (ISTH). RESULTS: The trial enrolled 402 patients (201 per arm), and the median follow-up was 3.5 (IQR 2.6-4.2) years. Bleeding occurred in 24 patients (29 events) and 32 patients (40 events) in the LAAC and NOAC groups, respectively. Six of the LAAC bleeding events were procedure/device-related. In the primary intention-to-treat analysis, LAAC was associated with similar rates of ISTH major or CRNMB (sHR 0.75, 95% CI 0.44-1.27, p = 0.28), but with a reduction in nonprocedural major or CRNMB (sHR 0.55, 95% CI 0.31-0.97, p = 0.039). This reduction for nonprocedural bleeding with LAAC was mainly driven by a reduced rate of CRNMB (sHR for major bleeding 0.69, 95% CI 0.34-1.39, p = .30; sHR for CRNMB 0.43, 95% CI 0.18-1.03, p = 0.059). History of bleeding was a predictor of bleeding during follow-up. Gastrointestinal bleeding was the most common bleeding site in both groups. CONCLUSION: During the 4-year follow-up, LAAC was associated with less nonprocedural bleeding. The reduction is mainly driven by a decrease in CRNMB.

BACKGROUND: Clinical outcomes and treatment selection after completing the randomized phase of modern trials, investigating antiplatelet therapy (APT) after percutaneous coronary intervention (PCI), are unknown. OBJECTIVES: The authors sought to investigate cumulative 15-month and 12-to-15-month outcomes after PCI during routine care in the MASTER DAPT trial. METHODS: The MASTER DAPT trial randomized 4,579 high bleeding risk patients to abbreviated (n = 2,295) or standard (n = 2,284) APT regimens. Coprimary outcomes were net adverse clinical outcomes (NACE) (all-cause death, myocardial infarction, stroke, and BARC 3 or 5 bleeding); major adverse cardiac and cerebral events (MACCE) (all-cause death, myocardial infarction, and stroke); and BARC type 2, 3, or 5 bleeding. RESULTS: At 15 months, prior allocation to a standard APT regimen was associated with greater use of intensified APT; NACE and MACCE did not differ between abbreviated vs standard APT (HR: 0.92 [95% CI: 0.76-1.12]; P = 0.399 and HR: 0.94 [95% CI: 0.76-1.17]; P = 0.579; respectively), as during the routine care period (HR: 0.81 [95% CI: 0.50-1.30]; P = 0.387 and HR: 0.74 [95% CI: 0.43-1.26]; P = 0.268; respectively). BARC 2, 3, or 5 was lower with abbreviated APT at 15 months (HR: 0.68 [95% CI: 0.56-0.83]; P = 0.0001) and did not differ during the routine care period. The treatment effects during routine care were consistent with those observed within 12 months after PCI. CONCLUSIONS: At 15 months, NACE and MACCE did not differ in the 2 study groups, whereas the risk of major or clinically relevant nonmajor bleeding remained lower with abbreviated compared with standard APT.

AIMS: As the antithrombotic regimen that may best prevent ischaemic complications along with the lowest bleeding risk offset following transcatheter aortic valve implantation (TAVI) remains unclear, we aimed to compare the safety and efficacy of antithrombotic regimens in patients without having an indication for chronic oral anticoagulation. METHODS AND RESULTS: We conducted a PROSPERO-registered (CRD42021247924) systematic review and network meta-analysis of randomized controlled trials evaluating post-TAVI antithrombotic regimens up to April 2022. We estimated the relative risk (RR) and 95% confidence intervals (95% CIs) using a random-effects model in a frequentist pairwise and network metanalytic approach. We included seven studies comprising 4006 patients with a mean weighted follow-up of 12.9 months. Risk of all-cause death was significantly reduced with dual antiplatelet therapy (DAPT) compared with low-dose rivaroxaban + 3-month single antiplatelet therapy (SAPT) (RR 0.60, 95% CI 0.41-0.88), while no significant reduction was observed with SAPT vs. DAPT (RR 1.02, 95% CI 0.67-1.58) and SAPT and DAPT compared with apixaban or edoxaban (RR 0.60, 95% CI 0.32-1.14 and RR 0.59, 95% CI 0.34-1.02, respectively). SAPT was associated with a significant reduction of life-threatening, disabling, or major bleeding compared with DAPT (RR 0.45, 95% CI 0.29-0.70), apixaban or edoxaban alone (RR 0.45, 95% CI 0.25-0.79), and low-dose rivaroxaban + 3-month SAPT (RR 0.30, 95% CI 0.16-0.57). There were no differences between the various regimens with respect to myocardial infarction, stroke, or systemic embolism. CONCLUSION: Following TAVI in patients without an indication for chronic oral anticoagulant, SAPT more than halved the risk of bleeding compared with DAPT and direct oral anticoagulant-based regimens without significant ischaemic offset.
