Abstract
BACKGROUND Approximately 18% of patients with atrial fibrillation undergo a percutaneous coronary intervention (PCI) to treat coronary heart disease. Pharmacological anticoagulation in patients with atrial fibrillation and PCI involves a trade-off of potential ischemic and hemorrhagic complications. METHODS This review is based on pertinent publications that were retrieved by a selective literature search, including current guidelines and recommendations. RESULTS Dual antiplatelet therapy (DAPT) with acetylsalicylic acid (ASA) and a P2Y12 inhibitor protects against stent thrombosis, but not against thromboembolic stroke. In contrast, oral anticoagulation does provide effective prevention against stroke during atrial fibrillation. Combining DAPT with oral anticoagulation (triple therapy) over the long term, as has been recommended to date, carries an elevated risk of hemorrhage. In a randomized controlled trial, 44% of patients with atrial fibrillation receiving triple therapy sustained a hemorrhagic event, compared to 19.4% of patients receiving dual therapy. A meta-analysis has shown that clinically relevant hemorrhage is less common under combined treatment with one of the new oral anticoagulants (NOAC) and a single antiplatelet drug than under triple therapy including a vitamin K antagonist (hazard ratio, 0.56; 95% confidence interval 0.39; 0.80]), but no significant difference was found with respect to stent thrombosis, myocardial infarction, or overall mortality. CONCLUSION After coronary stent implantation, dual therapy with a NOAC and a P2Y12 inhibitor is recommended, subsequent to triple therapy given only during the peri-interventional period.

Antithrombotic strategies in elderly patients with atrial fibrillation revascularized with drug-eluting stents: PACO-PCI (EPIC-15) registry. Int J Cardiol 2021; 338:63-71. [PMID: 34062196 DOI: 10.1016/j.ijcard.2021.05.036] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 04/28/2021] [Accepted: 05/20/2021] [Indexed: 01/08/2023]
Abstract
BACKGROUND We sought to investigate the antithrombotic regimens applied and their prognostic effects in patients over 75 years old with atrial fibrillation (AF) after revascularization with drug-eluting stents (DES). METHODS Retrospective registry in 20 centers including patients over 75 years with AF treated with DES. A primary endpoint of MACCE and a co-primary endpoint of major bleeding by ISTH criteria were considered at 12 months. RESULTS A total of 1249 patients (81.1 ± 4.2 years, 33.1% women, 66.6% ACS, 30.6% complex PCI) were included. Triple antithrombotic therapy (TAT) was prescribed in 81.7% and dual antithrombotic therapy (DAT) in 18.3%. TAT was based on direct oral anticoagulants (DOAC) in 48.4% and maintained for only 1 month in 52.2%, and DAT included DOAC in 70.6%. Primary endpoint of MACCE was met in 9.6% and primary endpoint of major bleeding in 9.4%. TAT was significantly associated with more bleeding (10.2% vs. 6.1%, p = 0.04) but less MACCE (8.7% vs. 13.6%, p = 0.02) than DAT and the use of DOAC was significantly associated to less bleeding (8% vs. 11.1%, p = 0.03) and similar MACCE (9.8% vs. 9.4%, p = 0.8). TAT over 1 month or with VKA was associated with more major bleeding but comparable MACCE rates. CONCLUSIONS Despite advanced age TAT prevails, but duration over 1 month or the use of other agent than Apixaban are associated with increased bleeding without additional MACCE prevention. DAT reduces bleeding but with a trade-off in terms of ischemic events. DOAC use was significantly associated to less bleeding and similar MACCE rates.

Abstract
BACKGROUND Although the number of vascular surgeries performed is increasing, the incidence of complications associated with this surgery has not improved and re-operations are frequently required. Thrombosis in a vessel is the most hazardous postoperative complication. OBJECTIVE The aim of this study was to evaluate the anti-thrombotic and anti-inflammatory effects of sulodexide compared to aspirin in a rat model. METHODS We divided the animals into three groups (sham (saline), aspirin, and sulodexide). The abdominal aorta was surgically opened and closed, primarily with 8/0 Prolene sutures. Postoperatively, saline, aspirin, or sulodexide was administered by oral gavage for 14 days to the rats. The degree of neovascularization, thrombus, calcification, inflammatory infiltrates, and fibrosis were analyzed histopathologically by hematoxylin and eosin staining. RESULTS There was no significant difference in the incidence of postoperative thrombogenesis, but less calcification and inflammatory infiltrates were observed in the sulodexide group compared to the aspirin group. Histopathologic score revealed less infiltration of inflammatory cells and mild calcification for the sulodexide group (0.17±0.41 and 1.33±0.52, respectively) compared to the aspirin group (0.67±0.52 and 1.67±0.52, respectively) at days 14. CONCLUSIONS This study offers the possibility that sulodexide could be used as an aspirin substitute for the postoperative management of vascular patients, with low gastrointestinal discomfort. In addition, it may also offer reduced postoperative calcification and inflammation.

Abstract
BACKGROUND Data on the optimal therapeutic international normalized ratio (INR) for non-valvular and valvular atrial fibrillation (AF) in Indonesia is currently unavailable. Therefore, we designed the Indonesian Registry on Atrial Fibrillation (OneAF) registry in order to seek a safe and beneficial range of INR in Indonesian patients with non-valvular and valvular AF. METHODS/DESIGN The OneAF registry is a nationwide collaboration of the Indonesian Heart Rhythm Society (InaHRS) enrolling all hospitals with cardiac electrophysiologists in Indonesia. It is a prospective, multicentre, nationwide, observational study aiming to recruit non-valvular and valvular AF patients in Indonesia. The registry was started in January 2020 with a planned 2 years of recruitment. There are 2 respondents for this registry: non-cohort and cohort respondents. Non-cohort registry respondents are AF patients at hospitals who fulfill inclusion and exclusion criteria but did not consent for a 24 month follow up. Whereas patients who consented for a 24 month follow up were included as cohort registry respondents. Key data collected includes basic sociodemographic information, symptoms and signs, medical history, results of physical examination and laboratory test, details of diagnostics and treatment measures and events. RESULTS Currently, a total of 1568 respondents have been enrolled in the non-cohort registry, including 1065 respondents with non-valvular AF (67.8%) and 503 respondents with valvular AF (32.2%). We believe that the OneAF registry will provide insight into the regional variability of anticoagulant treatment for AF, the implementation of rhythm/rate control approaches, and the clinical outcomes concerning cardiocerebrovascular events. TRIAL REGISTRATION Registered at clinicaltrials.gov (NCT04222868).

Abstract
Stroke is one of the main causes of mortality and permanent disability. Secondary prevention of stroke recurrence therefore has a high priority. Secondary prevention of ischemic stroke includes optimization of the lifestyle and diet, treatment of risk factors, such as hypertension, diabetes mellitus and hyperlipidemia, prophylaxis of recurrence with antiplatelet treatment in patients with high vascular risk and anticoagulation in atrial fibrillation. In addition, secondary prevention includes carotid surgery or stenting in selected symptomatic patients and closure of a patent foramen ovale after cryptogenic stroke.

Abstract
Atrial fibrillation (AF) is an important risk factor for ischemic stroke resulting in a fivefold increased stroke risk and a twofold increased mortality. Our understanding of stroke mechanisms in AF has evolved since the concept of atrial cardiopathy was introduced as an underlying pathological change, with both AF and thromboembolism being common manifestations and outcomes. Despite the strong association with stroke, there is no evidence that screening for AF in asymptomatic patients improves clinical outcomes; however, there is strong evidence that patients with embolic stroke of undetermined source may require long-term monitoring to detect silent or paroxysmal AF. Stroke prevention in patients at risk, assessed by the CHA2DS2-VASc score, was traditionally achieved with warfarin; however, direct oral anticoagulants have solidified their role as safe and effective alternatives. Additionally, left atrial appendage exclusion has emerged as a viable option in patients intolerant of anticoagulation. When patients with AF have an acute stroke, the timing of initiation or resumption of anticoagulation for secondary stroke prevention has to be balanced against the risk of hemorrhagic conversion. Multiple randomized clinical trials are currently underway to determine the best timing for administration of anticoagulants following acute ischemic stroke.

Abstract
Prevention of ischemic stroke relies on the use of antithrombotic medications comprising antiplatelet agents and anticoagulation. Stroke risk is particularly high in patients with cardiovascular disease. This review will focus on the role of antithrombotic therapies in the context of different types of cardiovascular disease. We will discuss oral antiplatelet medications and both IV and parental anticoagulants. Different kinds of cardiovascular disease contribute to stroke via distinct pathophysiological mechanisms, and the optimal treatment for each varies accordingly. We will explore the mechanism of stroke and evidence for antithrombotic therapy in the following conditions: atrial fibrillation, prosthetic heart values (mechanical and bioprosthetic), aortic arch atherosclerosis, congestive heart failure (CHF), endocarditis (infective and nonbacterial thrombotic endocarditis), patent foramen ovale (PFO), left ventricular assist devices (LVAD), and extracorporeal membrane oxygenation (ECMO). While robust data exist for antithrombotic use in conditions such as atrial fibrillation, optimal treatment in many situations remains under active investigation.

Abstract
OBJECTIVES The aim of this study was to explore the early versus late benefits and risks of dabigatran dual therapy versus warfarin triple therapy in the RE-DUAL PCI (Randomized Evaluation of Dual Antithrombotic Therapy With Dabigatran Versus Triple Therapy With Warfarin in Patients With Nonvalvular Atrial Fibrillation Undergoing Percutaneous Coronary Intervention) trial. BACKGROUND Patients with atrial fibrillation who undergo percutaneous coronary intervention are at increased risk for both bleeding and thrombotic events. METHODS A total of 2,725 patients with atrial fibrillation underwent percutaneous coronary intervention and were randomized to receive dabigatran 110 mg, or dabigatran 150 mg plus a P2Y12 inhibitor (and no aspirin), or warfarin plus a P2Y12 inhibitor plus aspirin. Landmark analysis was performed at 30 and 90 days. RESULTS There was a consistent and large reduction in major or clinically relevant nonmajor bleeding in patients randomized to dual therapy during the first 30 days (110 mg: hazard ratio [HR]: 0.45; 95% confidence interval [CI]: 0.31 to 0.66; p < 0.0001; 150 mg: HR: 0.46; 95% CI: 0.30 to 0.72; p = 0.0006) compared with warfarin triple therapy. There was early net clinical benefit in both dabigatran groups versus warfarin (110 mg: HR: 0.65; 95% CI: 0.47 to 0.88; p = 0.0062; 150 mg: HR: 0.54; 95% CI: 0.37 to 0.79; p = 0.0015), due to larger reductions in bleeding than increased thrombotic events for dabigatran 110 mg and bleeding reduction without increased thrombotic risk for dabigatran 150 mg dual therapy versus warfarin triple therapy. After the removal of aspirin in the warfarin group, bleeding remained lower with dabigatran 110 mg and was similar with dabigatran 150 mg versus warfarin. CONCLUSIONS In RE-DUAL PCI, in which patients in the dual-therapy arms were treated with aspirin for an average of only 1.6 days, there was early net clinical benefit with both doses of dabigatran dual therapy, without an increase in thrombotic events with dabigatran 150 mg. This could be helpful in the subset of patients with elevated risk for both bleeding and thrombotic events.

Abstract
In patients with atrial fibrillation who undergo percutaneous coronary intervention (PCI), both anticoagulation and dual antiplatelet therapy (aspirin plus a P2Y12 inhibitor) are indicated. However, this "triple" antithrombotic therapy is associated with high rates of bleeding. Finding the right balance of reducing ischemic risk and protecting coronary stents from restenosis while not increasing bleeding risk is difficult. In the past 5 years, 6 randomized clinical trials have shown the benefit of dropping aspirin from the triple therapy regimen to create "dual" therapy (oral anticoagulants and P2Y12 inhibitors alone) with reductions in bleeding without a significant increase in ischemic events. Because of small trends toward higher risk of stent thrombosis, especially in higher risk patients with acute coronary syndromes, current recommendations call for dual therapy as the "default" regimen, but that risk stratification be used to help inform the decision on potentially using a brief period of triple therapy in selected high ischemic risk patients. For long-term therapy (after one year post-PCI), recent studies have found oral anticoagulation alone without any antiplatelet therapy has a favorable benefit risk ratio. Thus, while dropping aspirin at varying times post-PCI has become an attractive strategy in many patient groups, careful patient selection and individualized assessment of the risk:benefit balance is warranted.

Abstract
Background It is unknown about the influence of prestroke antiplatelet use on early outcomes in patients with and without the indication. We aimed to evaluate the in-hospital prognosis of first-ever noncardiogenic ischemic stroke patients with and without indications of antiplatelet use for primary prevention. Methods This was a retrospective, observational study based on a prospective hospital-based registry (Chinese Stroke Center Alliance). Using the data with 436,660 first-ever noncardiogenic acute ischemic strokes recorded from Aug 1, 2015, to July 31, 2019, from 1,453 hospitals in China, we examined the associations between the indication for prestroke antiplatelet use and in-hospital clinical outcomes. Results Among 436,660 first-ever noncardiogenic ischemic stroke patients, 42,409 patients (9.7%) had a documented previous vascular indication and 394,251 (90.3%) did not. Compared to those without, patients with the indication were associated with increased prevalence of in-hospital morbid conditions, including stroke severity (OR 2.71; 95% CI: 2.62–2.81; P<0.0001), length of stay >14 days (OR 1.16; 95% CI: 1.13–1.19; P<0.0001), mortality (OR 2.20; 95% CI: 1.96–2.46, P<0.0001), and recurrence of ischemic stroke and transient ischemic attack (TIA) (OR 1.5; 95% CI: 1.43–1.59, P<0.0001). Among patients without indication, prestroke antiplatelet use was associated with lower mortality (OR 0.73, 95% CI: 0.56–0.96; P=0.0221); while among patients with indication, those receiving prestroke antiplatelet had lower odds ratios in stroke severity (P<0.0001) and disability (P=0.0003) than those who not. Conclusions Patients with indications of prestroke antiplatelet use were more likely to have unfavorable outcomes than those without. Prestroke antiplatelet might be associated with lower mortality, less disability, and less stroke severity in certain population groups. Future studies to improve risk prediction rules are needed to guide effective primary prevention for ischemic stroke.

Long term risk and costs of bleeding in men and women treated with triple antithrombotic therapy-An observational study. PLoS One 2021; 16:e0248359.

Abstract
OBJECTIVES Bleeding is the most common non-ischemic complication in patients with coronary revascularisation procedures, associated with prolonged hospitalisation and increased mortality. Many factors predispose for bleeds in these patients, among those sex. Anyhow, few studies have characterised the population receiving triple antithrombotic therapy (TAT) as well as long term bleeds from a sex perspective. We investigated the one year rate of bleeds in patients receiving TAT, potential sex disparities and premature discontinuation of TAT. We also assessed health care costs in bleeders vs non-bleeders. SETTING Three hospitals in the County of Östergötland, Sweden during 2009-2015. PARTICIPANTS All patients discharged with TAT registered in the SWEDEHEART registry. PRIMARY AND SECONDARY OUTCOME MEASURES All bleeds receiving medical attention during one-year follow-up were collected by retrieving relevant information about each patient from medical records. Resource use associated with bleeds was assigned unit cost to estimate the health care costs associated with bleeding episodes. RESULTS Among 272 patients, 156 bleeds occurred post-discharge, of which 28.8% were gastrointestinal. In total 54.4% had at least one bleed during or after the index event and 40.1% bled post discharge of whom 28.7% experienced a TIMI major or minor bleeding. Women discontinued TAT prematurely more often than men (52.9 vs 36.1%, p = 0.01) and bled more (48.6 vs. 37.1%, p = 0.09). One-year mean health care costs were EUR 575 and EUR 5787 in non-bleeding and bleeding patients, respectively. CONCLUSION The high bleeding incidence in patients with TAT, especially in women, is a cause of concern. There is a need for an adequately sized randomised, controlled trial to determine a safe but still effective treatment for these patients.

Characteristics and antithrombotic treatment patterns of patients with concomitant coronary artery disease and atrial fibrillation from Thailand's COOL-AF registry. BMC Cardiovasc Disord 2021; 21:117. [PMID: 33653277 PMCID: PMC7927385 DOI: 10.1186/s12872-021-01928-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2020] [Accepted: 02/18/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Concomitant coronary artery disease (CAD) and atrial fibrillation (AF) are common in clinical practice. The aim of this study was to investigate the characteristics and antithrombotic treatment patterns of patients with concomitant CAD and AF from the COhort of antithrombotic use and Optimal INR Level in patients with non-valvular atrial fibrillation in Thailand (COOL-AF Thailand) registry. METHODS Registry enrollment criteria included patients aged ≥ 18 years who were diagnosed with AF for any duration at any of 27 public hospitals located across Thailand during 2014-2017. The That Clinical Trials Registry study registration number is TCTR20160113002. Statistical comparisons of characteristics and treatment strategies were performed between patients with and without CAD. RESULTS Of a total of 3461 AF patients, 557 had concomitant CAD (16.1%). Patients with concomitant CAD and AF were significantly older, more likely to be male, had more comorbidities, and had more cardiovascular implantable electronic devices. History of stroke/transient ischemic attack and prior bleeding was not significantly different between groups. CHA2DS2-VASc score and HAS-BLED score were both higher in patients with CAD than in patients without CAD (4.17 vs. 2.78, p < 0.001, and 2.01 vs. 1.45, p < 0.001, respectively). Utilization of oral anticoagulant was less in patients with CAD (76.0% vs. 84.3%, p < 0.001). Concomitant use of antiplatelet was found to be a major cause of oral anticoagulant (OAC) underutilization. Specifically, the rate of OAC prescription was 95.9% in patients without antiplatelet, and 43.7% in patients with antiplatelet. Among patients with CAD who were on OAC, the rate of concomitant antiplatelet prescription was still high. In this group, 63% of patients were on triple therapy when percutaneous coronary intervention (PCI) with drug eluting stent was performed within 1 year, and 32.2% of patients without prior PCI or acute coronary syndrome were taking at least one antiplatelet with OAC. CONCLUSION Among patients with concomitant CAD and AF, physicians were reluctant to discontinue antiplatelet. The use of antiplatelet discourages physicians from prescribing OAC. Underutilization of OAC may increase the risk of ischemic stroke, and an inappropriate combination of OAC and antiplatelet may increase the risk of bleeding. Trial registration The trial has been registered with the Thai Clinical Trials Registry (TCTR) which complied with WHO International Clinical Trials Registry Platform dataset. The Registration Number is TCTR20160113002 (05/01/2016).

Abstract
BACKGROUND Biological data suggest that short-term anticoagulation would be more effective than dual antiplatelet therapy (DAPT) to reduce the thrombotic risk following left atrial appendage closure (LAAC). This study sought to assess the safety and efficacy of direct oral anticoagulation (DOAC) versus DAPT immediately post-LAAC. METHODS Multicenter study including 592 consecutive patients with relative contraindication to chronic anticoagulation who underwent LAAC and received either DAPT or DOAC for 1-3 months. Each patient receiving DOAC was matched with 2 patients on DAPT based on propensity-score (propensity-matched population of 285 patients). Outcomes recorded were death, stroke, non-procedural related severe bleeding, serious adverse event (SAE: composite of death, stroke, bleeding) and early (within 3 months post-LAAC) device-related thrombosis (DRT). RESULTS Early outcomes (within 3-month post-LAAC) did not significantly differ between groups, but a numerically higher rate of early death (3.7% vs. 1.1%), non-procedural related severe bleeding (7.4% vs. 3.2%), and SAE (11.1% vs. 5.3%) were observed in patients receiving DAPT. After a median follow-up of 22 (8-38) months, similar outcomes were observed in DAPT and DOAC groups regarding death (HR: 1.18; 95% CI: 0.58-2.37; p = 0.652), stroke (HR: 1.01; 95% CI: 0.22-5.45; p = 0.908), non-procedural related severe bleeding (HR: 1.68; 95% CI: 0.69-4.12; p = 0.257), and SAE (HR: 1.28; 95% CI: 0.73-2.24; p = 0.383). DRT was identified in 4 patients (2.6%) receiving DAPT versus 0 patient receiving DOAC (p = 0.162). CONCLUSIONS Short-term DOAC following LAAC in patients with contraindications to chronic anticoagulation was safe and tended to associate with a lower rate of SAE and DRT compared to DAPT.

Abstract
A growing number of patients undergoing percutaneous coronary intervention (PCI) with stent implantation also have atrial fibrillation. This poses challenges for their optimal antithrombotic management because patients with atrial fibrillation undergoing PCI require oral anticoagulation for the prevention of cardiac thromboembolism and dual antiplatelet therapy for the prevention of coronary thrombotic complications. The combination of oral anticoagulation and dual antiplatelet therapy substantially increases the risk of bleeding. Over the last decade, a series of North American Consensus Statements on the Management of Antithrombotic Therapy in Patients with Atrial Fibrillation Undergoing Percutaneous Coronary Intervention have been reported. Since the last update in 2018, several pivotal clinical trials in the field have been published. This document provides a focused updated of the 2018 recommendations. The group recommends that in patients with atrial fibrillation undergoing PCI, a non-vitamin K antagonist oral anticoagulant is the oral anticoagulation of choice. Dual antiplatelet therapy with aspirin and a P2Y12 inhibitor should be given to all patients during the peri-PCI period (during inpatient stay, until time of discharge, up to 1 week after PCI, at the discretion of the treating physician), after which the default strategy is to stop aspirin and continue treatment with a P2Y12 inhibitor, preferably clopidogrel, in combination with a non-vitamin K antagonist oral anticoagulant (ie, double therapy). In patients at increased thrombotic risk who have an acceptable risk of bleeding, it is reasonable to continue aspirin (ie, triple therapy) for up to 1 month. Double therapy should be given for 6 to 12 months with the actual duration depending on the ischemic and bleeding risk profile of the patient, after which patients should discontinue antiplatelet therapy and receive oral anticoagulation alone.

Abstract
Background and Objectives Antithrombotic therapy after percutaneous coronary intervention (PCI) in patients with atrial fibrillation (AF) has changed in recent years with new data from large randomized trials and updates to clinical guidelines. This study aimed to investigate the trends in periprocedural antithrombotic regimens in Korean patients with AF undergoing PCI with non-vitamin K antagonist oral anticoagulants (NOACs). Methods Using the claims database of the Health Insurance Review and Assessment during 2013–2018, 27,594 patients with AF undergoing PCI were identified. The annual prevalence of PCI and prescriptions of each antithrombotic agent, including antiplatelet agents and oral anticoagulants, within 30 days after PCI were investigated. Results During 2013–2018, the number of patients with AF undergoing PCI increased up to 1.3-fold (from 3,913 to 5,075 patients per year). After the introduction of NOACs, the proportion of dual antiplatelet therapy (DAPT) decreased from 71.9% to 49.8% but still occupied the largest proportion among antithrombotic regimens. Triple antithrombotic therapy (TAT) use increased from 25.4% to 46.0%, and NOAC has rapidly replaced warfarin as the oral anticoagulant of choice. TAT was preferred to DAPT for patients with CHA2DS2-VASc score ≥2. Among various factors, prior intracranial hemorrhage was the most powerful predictor of favoring DAPT use over TAT. Conclusion Since the introduction of NOACs, the patterns of periprocedural antithrombotic regimens have changed rapidly toward more use of TAT, specifically with NOAC-based regimen. Appropriate stroke prevention with oral anticoagulants is still underutilized in patients with AF undergoing PCI in Korea.

Abstract
BACKGROUND The optimal antithrombotic treatment for patients with atrial fibrillation (AF) that undergo percutaneous coronary intervention (PCI) is controversial. Dual therapy (clopidogrel and a direct oral anticoagulant [DOAC]) is safer than triple therapy (warfarin, aspirin, and clopidogrel), while efficacy is unclear. We aimed to evaluate thrombin generation (TG) under dual and triple therapy. METHODS A noninterventional prospective trial in patients with AF undergoing PCI. Patients received 4 weeks of triple therapy with aspirin, clopidogrel, and a DOAC followed by aspirin withdrawal. TG was measured in platelet-rich plasma (PRP) and platelet-poor plasma (PPP) at 3 five to 21 points, day 1 after PCI (TIME 0), 4 weeks after PCI (TIME 1), and 2 weeks after aspirin withdrawal (TIME 2). RESULTS Twenty-three patients (18 men, median age 78 years, 83% with acute coronary syndrome) were included. Endogenous thrombin potential (ETP) in PPP was high at TIME 0 compared with TIME 1 (ETP 3,178 ± 248 nM vs. 2,378 ± 222 nM, p = 0.005). These results remained consistent when measured in PRP. No significant difference in ETP was found before (TIME 1) and after aspirin withdrawal (TIME 2) although few patients had high ETP levels after stopping aspirin. CONCLUSIONS TG potential is high immediately after PCI and decreases 4 weeks after PCI in patients receiving triple therapy. TG remains constant after aspirin withdrawal in most patients, suggesting that after 1 month the antithrombotic effect of dual therapy may be similar to triple therapy.

Abstract
PURPOSE OF REVIEW The association between atrial fibrillation and stroke is firmly established, and anticoagulation reduces stroke risk in patients with atrial fibrillation. However, the role of anticoagulation in very brief durations of atrial fibrillation (subclinical atrial fibrillation) is an area of controversy. RECENT FINDINGS Stroke risk increases alongside burden of atrial fibrillation. Ongoing trials will clarify if 24 h or less of atrial fibrillation on extended monitoring necessitates lifelong anticoagulation. Trials examining empiric anticoagulation for individuals with ESUS did not demonstrate benefit over antiplatelet agents. However, hypothesis-generating sub-analyses suggest that certain at-risk groups may benefit. Atrial cardiopathy is associated with subclinical atrial fibrillation and research examining anticoagulation after ESUS in this population is underway. SUMMARY Stroke risk increases alongside burden of ectopic atrial activity. However, this risk may in part be because of prothrombotic dysfunction associated with atrial cardiopathy in addition to the arrhythmia itself. The minimal amount of subclinical atrial fibrillation to warrant anticoagulation for stroke prevention, and how this may be modified by the total duration of monitoring, will be clarified by the results of ongoing clinical trials. Currently research will also help identify whether a select group of ESUS patients who have structural and electrophysiological markers of atrial cardiopathy warrant anticoagulation for secondary prevention.

Abstract
Patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) have traditionally received triple antithrombotic therapy (TAT) consisting of aspirin and a P2Y12 inhibitor plus an oral anticoagulant (OAC) to reduce atherothrombotic events, even though this strategy is associated with a high risk of severe bleeding. Recent trials have indicated that dual antithrombotic therapy (DAT), consisting of a P2Y12 inhibitor plus an OAC, may be superior to TAT in terms of bleeding risk; however, the trade-off regarding ischemic complications may be questionable. Patients who have had a myocardial infarction (MI) before undergoing PCI warrant special consideration because of the accompanying high ischemic risk, including stent thrombosis, which might be exacerbated by an aspirin-free strategy such as DAT. In particular, in the acute phase of ST-segment elevation MI (STEMI), the highly prothrombotic milieu may necessitate initial TAT, though durations may vary, making a tailored antithrombotic regimen for this high-risk subset of patients a fairly challenging and difficult scenario for clinicians. Since patients with MI, especially STEMI, are underrepresented in randomized trials, data regarding the optimal antithrombotic treatment in such patients are sparse. This review aims to analyze the outcomes of different antithrombotic regimens in patients with MI and AF undergoing PCI, define the role of DAT versus TAT regarding safety and efficacy outcomes, and address controversial issues and future perspectives.

The efficacy and safety of Hirudin plus Aspirin versus Warfarin in the secondary prevention of Cardioembolic Stroke due to Nonvalvular Atrial Fibrillation: A multicenter prospective cohort study. Int J Med Sci 2021; 18:1167-1178. [PMID: 33526977 PMCID: PMC7847633 DOI: 10.7150/ijms.52752] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Accepted: 12/22/2020] [Indexed: 11/05/2022] Open
Abstract
Background: To investigate the efficacy and safety of hirudin plus aspirin therapy compared with warfarin in the secondary prevention of cardioembolic stroke due to nonvalvular atrial fibrillation (NVAF). Methods: Patients with cardioembolic stroke due to NVAF were prospectively enrolled from 18 collaborating hospitals from Dec 2011 to June 2015. Fourteen days after stroke onset, eligible patients were assigned to the hirudin plus aspirin group (natural hirudin prescribed as the traditional Chinese medicine Maixuekang capsule, 0.75 g, three times daily, combined with aspirin 100 mg, once daily) or the warfarin group (dose-adjusted warfarin targeting international normalized ratio (INR) 2-3, with an initial daily dose of 1.25 mg). Patients were followed up at 1, 2, 3, 6, 9, and 12 months after stroke onset. Time in therapeutic range (TTR) was calculated according to Rosendaal methodology to evaluate the quality of INR management in the warfarin group. The primary efficacy endpoint was the recurrence of stroke within 12 months after stroke onset. Safety was assessed as the occurrence of the composite event "intracranial hemorrhage and other bleeding events, death, and other serious adverse events". The Cox proportional hazard model and Kaplan-Meier curve were used to analyze the efficacy and safety events. Results: A total of 221 patients entered final analysis with 112 patients in the hirudin plus aspirin group and 109 in the warfarin group. Over the whole duration of our study, TTR for patients taking warfarin was 66.5 % ± 21.5%. A significant difference was not observed in the recurrence of stroke between the two groups (3.57% vs. 2.75%; P = 0.728). The occurrence of safety events was significantly lower in the hirudin plus aspirin group (2.68% vs.10.09%; P = 0.024). The risk for efficacy event was similar between the two groups (hazard ratio (HR), 1.30; 95% confidence interval (CI), 0.29-5.80). The safety risk was significantly lower in the hirudin plus aspirin group (HR, 0.27; 95% CI, 0.07-0.95). Kaplan-Meier analysis revealed significant difference in the temporal distribution in safety events (P = 0.023) but not in stroke recurrence (P = 0.726). Conclusion: Significant difference in efficacy was not detected between warfarin group and hirudin plus aspirin group. Compared with warfarin, hirudin plus aspirin therapy had lower safety risk in the secondary prevention of cardioembolic stroke due to NVAF.

Abstract
Atrial fibrillation is a common cardiac arrhythmia that carries a risk of stroke. This is commonly stratified with the CHA2DS2-VASc score. Stroke risk can be reduced with anticoagulants or with interventions to close the left atrial appendage, the most common source of left atrial thrombi. While warfarin has been traditionally used as the only oral anticoagulant available, there are several direct oral anticoagulants that compare favorably with respect to both stroke and bleeding risk in randomized controlled trials. Multiple interventional options exist to close the left atrial appendage, but the Watchman device is the only one that compares favorably with warfarin in randomized controlled trials.

Abstract
Stroke is a leading cause of permanent disability. Therefore, primary prevention of first stroke and secondary prevention of recurrent stroke are a high priority. Primary prevention of ischemic stroke includes lifestyle modification and diet, treatment of risk factors including hypertension, diabetes mellitus and lipid disorders, antiplatelet therapy for high vascular risk patients, and anticoagulation in atrial fibrillation. Secondary prevention of ischemic stroke includes additional carotid surgery or stenting in selected symptomatic patients, closure of patent foramen ovale after cryptogenic stroke, treatment of insulin resistance, and best medical treatment of intracranial stenosis. The most important preventive strategies in the primary and secondary prevention of cerebral hemorrhage include the treatment of hypertension, reduction in alcohol intake, and occlusion of the left atrial appendage in patients with atrial fibrillation and permanent contraindications for oral anticoagulation.

Abstract
OBJECTIVES Spontaneous recanalization of a chronic total occlusion of the extra-cranial internal carotid artery is an under-reported clinical entity. This paper reviews the different etiologies of internal carotid artery occlusion, its natural course, as well as the significance and our recommendations for the management of spontaneous internal carotid artery recanalization. METHODS A review of literature on etiology, diagnosis, and treatment of internal carotid artery occlusion and recanalization was conducted. PubMed database was searched using the terms "internal carotid occlusion" and "recanalization". Articles were reviewed and studies involving the management of internal carotid artery occlusion and spontaneous recanalization were included. We subsequently developed a management algorithm for chronic total occlusion of the internal carotid artery and spontaneous recanalization of such lesions based on the available evidence. RESULTS Common etiologies of chronic total occlusion of the internal carotid artery include carotid atherosclerotic disease, cardioembolic, and carotid dissection. Progression of an asymptomatic to symptomatic occlusion is estimated at 2-8% annually. Well-compensated patients can be asymptomatic. In others, clinical symptoms range from ipsilateral or global hypoperfusion to embolic stroke in some cases of spontaneous recanalization. Spontaneous recanalization occurs in 2.3-10.3% of patients but rarely results in a cerebrovascular event. CONCLUSIONS Progression of an asymptomatic chronic total occlusion of the internal carotid artery to symptomatic is infrequent. The management algorithm of chronic total occlusion of the internal carotid artery and spontaneous recanalization of the internal carotid artery must be tailored to the patient based on symptoms, etiology of the lesion, imaging findings, surgical risk, and reliability for follow-up.

Abstract
OBJECTIVE Prior studies have demonstrated that anticoagulation underutilisation for atrial fibrillation (AF) and elevated stroke risk is common. However, there is little data on factors associated with appropriate anticoagulation, particularly in Indigenous Australians who face a disproportionate burden of AF and stroke. We thus sought to determine factors associated with anticoagulation use in Australians with AF. DESIGN Administrative, clinical, prescriptive and laboratory data were linked and aggregated over a 12-year period. SETTING Single tertiary teaching hospital. PARTICIPANTS 19,305 (98%) and 308 (2%) consecutive non-Indigenous and Indigenous Australians with AF identified from administrative databases. MAIN OUTCOME MEASURES Associations of anticoagulation use according to ethnicity. RESULTS Significant independent predictors of anticoagulation use included hypertension (odds ratio [OR] 1.25, 95% confidence interval [CI] 1.17-1.34; p<0.001), diabetes (OR 1.14, 95% CI 1.05-1.24; p=0.002), heart failure (OR 1.54 95% CI 1.43-1.66; p<0.001) and prior stroke or transient ischaemic attack (OR 2.07, 95% CI 1.84-2.33; p<0.001). In contrast, increasing age (OR 0.99, 95% CI 0.98-0.99; p<0.001), female gender (OR 0.88, 95% CI 0.82-0.93; p<0.001), and vascular disease (OR 0.72, 95% CI 0.64-0.80; p<0.001) were significant predictors of no anticoagulation. Hypertension was associated with less anticoagulation use in Indigenous compared to non-Indigenous Australians (p=0.02). CONCLUSIONS Anticoagulation for AF was suboptimal in both Indigenous and non-Indigenous Australians. Older age, female gender, and comorbid vascular disease were found to be negatively associated with anticoagulation. Importantly, hypertension may also be under-recognised as a stroke risk factor in Indigenous Australians. Future efforts to encourage anticoagulation use in accordance with guideline recommendations is likely to reduce the burden of AF-related stroke in both Indigenous and non-Indigenous populations.

Abstract
The Canadian Cardiovascular Society (CCS) atrial fibrillation (AF) guidelines program was developed to aid clinicians in the management of these complex patients, as well as to provide direction to policy makers and health care systems regarding related issues. The most recent comprehensive CCS AF guidelines update was published in 2010. Since then, periodic updates were published dealing with rapidly changing areas. However, since 2010 a large number of developments had accumulated in a wide range of areas, motivating the committee to complete a thorough guideline review. The 2020 iteration of the CCS AF guidelines represents a comprehensive renewal that integrates, updates, and replaces the past decade of guidelines, recommendations, and practical tips. It is intended to be used by practicing clinicians across all disciplines who care for patients with AF. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system was used to evaluate recommendation strength and the quality of evidence. Areas of focus include: AF classification and definitions, epidemiology, pathophysiology, clinical evaluation, screening and opportunistic AF detection, detection and management of modifiable risk factors, integrated approach to AF management, stroke prevention, arrhythmia management, sex differences, and AF in special populations. Extensive use is made of tables and figures to synthesize important material and present key concepts. This document should be an important aid for knowledge translation and a tool to help improve clinical management of this important and challenging arrhythmia.

Abstract
BACKGROUNDS We investigated the prognostic impact of antithrombotic regimens at 1-year after percutaneous coronary intervention (PCI) among patients with atrial fibrillation (AF). METHOD AND RESULTS A total of 13,278 AF patients who underwent PCI from 2009 to 2013 were selected from Korean National Health Insurance Service database. Patients were categorized by antithrombotic regimens at 1-year after PCI: (1) OAC with or without single antiplatelet (OAC±SAPT); (2) triple therapy (TT) and (3) antiplatelets (APT) only. After propensity score matching, composite ischaemia (death, myocardial infarction, and stroke), composite bleeding (intracranial hemorrhage and gastrointestinal bleeding), and a composite clinical outcome (composite ischaemia and bleeding) were compared. Of total population, 1,100 (8.3%), 746 (5.6%), and 11,432 (86.1%) were treated with OAC±SAPT, TT, and APT only, respectively. Compared to OAC±SAPT group, the TT group had significantly higher risk of the composite clinical outcome (hazard ratio [HR] 1.46, 95% confidence interval [CI] 1.00-2.13) attributed to a higher trend in both ischaemia (HR 1.63, 95% CI 0.99-2.67) and bleeding (HR 1.22, 95% CI 0.69-2.13). The APT only group showed a higher risk of ischaemia (HR 1.85, 95% CI 1.25-2.74), despite a lower risk of bleeding (HR 0.55, 95% CI 0.32-0.94) compared to OAC±SAPT group. CONCLUSIONS OAC±SAPT was associated with better clinical outcomes compared to TT or APT only treatments, beyond 1-year after PCI among Asians with AF.

Abstract
ZusammenfassungVorhofflimmern und auch Vorhofflattern sind aufgrund der mechanischen Stase im Vorhof mit einer hohen Thrombembolierate, also Schlaganfällen oder systemischen Thrombembolien, assoziiert. Die orale Antikoagulation reduziert die Rate der thrombembolischen Ereignisse um ca. ⅔, bei Einsatz von NOAC sogar noch etwas mehr. Bei älteren und alten Patienten ist das thrombembolische Risiko deutlich erhöht, insbesondere wenn Risikofaktoren wie arterielle Hypertonie, Herzinsuffizienz oder Niereninsuffizienz vorhanden sind. Ältere und alte Patienten profitieren von einer Antikoagulation aufgrund des höheren absoluten Risikos deutlich mehr als jüngere Patienten, obwohl sie auch ein erhöhtes Blutungsrisiko haben. Das Blutungsrisiko kann durch Behandlung modifizierbarer Risikofaktoren, Überprüfung bzw. Modifikation der Komedikation und patientenorientierte Dosierung der NOAC unter Berücksichtigung der Nierenfunktion deutlich reduziert werden. Dadurch können auch ältere und alte Patienten von einer effektiven Antikoagulation profitieren und Schlaganfälle verhindert werden.

Abstract
BACKGROUND Patients with atrial fibrillation undergoing percutaneous coronary intervention have indications for oral anticoagulation and dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor inhibitor. The concurrent use of all three agents, termed triple oral antithrombotic therapy (TAT), increases the risk of bleeding. A number of prospective trials showed that the omission of aspirin mitigates the risk of bleeding without affecting major adverse cardiovascular event (MACE). MATERIALS AND METHODS The databases of PubMed, Embase, and Cochrane Central databases were searched from inception to October 2019. Relevant randomized control trials comparing dual antithrombotic therapy (DAT) versus TAT were identified and a metanalysis was performed using random-effect model. The safety endpoints of interest were thrombolysis in myocardial infarction criteria (TIMI) major and minor bleeding, TIMI major bleeding, and intracranial bleeding. The efficacy endpoints of interest were MACE and individual components of MACE. RESULTS Six trials with 11,722 patients were included. For safety endpoint, DAT was associated with significantly lower incidence of TIMI major and minor bleeding [RR: 0.58, 95% CI 0.44-0.77, P = 0.0001], TIMI major bleeding [RR: 0.55, 95% CI 0.42-0.73, P < 0.0001] as well as intracranial bleeding [RR: 0.35, 95% CI 0.16-0.73, P = 0.006] compared with TAT. No significant difference was observed for MACE [RR: 0.96 (0.79-1.17) P = 0.71] or any of the individual components of MACE between the two groups. CONCLUSION Omission of aspirin from TAT in patients with Atrial Fibrillation (AF) after percutaneous coronary intervention is associated with lower risk of bleeding without compromising the efficacy in terms of mortality and cardiovascular thrombotic events.

Abstract
PURPOSE Patients with patent foramen ovale (PFO) and cryptogenic ischemic stroke (CS) are at risk for stroke recurrence. The optimal antithrombotic strategy in patients who undergo medical management is still debated. METHODS We systematically searched the literature for studies that reported on cerebrovascular event recurrences and/or death in patients with PFO treated with oral anticoagulation (OAC) or antiplatelet therapy (APT) for secondary prevention of CS. The efficacy endpoints were stroke recurrence and the composite of stroke, transient ischemic attack or all-cause death. Major bleedings represented the safety endpoint. RESULTS A total of 16 studies with 3953 patients (OAC = 1527, APT = 2426) were included. Weighted mean follow-up was 2.9 years. OAC was associated with a significant reduction in the risk of stroke compared with APT (RR 0.65; 95% CI 0.44-0.95; ARR 2%, NNT 49), while no difference was found regarding the composite outcome (RR 0.78; 95% CI 0.57-1.07) and the safety outcome (RR 1.57; 95% CI 0.85-2.90; p = 0.15). CONCLUSIONS OAC was more effective than APT in reducing the risk of stroke recurrence in patients with PFO and CS, without a significant increase in the risk of major bleedings. Our findings support the need for further randomized data focused on the comparison of antithrombotic strategies in this setting.

Abstract
Antithrombotic treatment in patients with atrial fibrillation undergoing percutaneous coronary intervention is still debated. We conducted a meta-analysis of recent randomized controlled trials to evaluate the benefit of different antithrombotic strategies. Data were analyzed between May and September 2019. Efficacy outcomes were trial-defined major adverse cardiovascular events (MACE); its individual components; stent thrombosis. Safety outcomes were trial-defined primary bleeding outcome; TIMI and ISTH major bleeding; clinically relevant non-major bleeding; intracranial hemorrhage. Differences in outcomes among groups were expressed as pooled odds ratio (OR) and corresponding 95% confidence interval (CI). Four randomized studies were included (10,969 patients). The mean age ranged from 69 to 72 years, prevalence of acute coronary syndrome (ACS) varied from 48 to 62%. Comparing dual antithrombotic therapy (DAT) with a direct oral anticoagulant (DOAC) versus triple antithrombotic therapy (TAT) with vitamin K antagonist (VKA), OR for trial-defined MACE and primary bleeding outcome were 1.03 (95% CI, 0.86-1.24) and 0.59 (95% CI, 0.41-0.86), respectively. There was a 68% lower risk of intracranial hemorrhage and a non-statistically significant higher risk of stent thrombosis with DAT. DAT was as effective and safer than TAT in patients with stable coronary artery disease, while a trend towards increased ischemic events was seen in ACS patients. DAT with a DOAC showed similar efficacy and less bleeding than TAT with a VKA. However, increased stent thrombosis with DAT may be present, and TAT should be considered in patients at high ischemic risk, such as ACS patients.

Abstract
The combination of atrial fibrillation (AF) and acute coronary syndrome (ACS) is a complex situation in which a three-dimensional risk-cardioembolic, coronary, and hemorrhagic-has to be carefully managed. Triple antithrombotic therapy (TAT) is burdened with a high risk of serious bleeding, while dual antithrombotic therapy with an anticoagulant (DAT) likely provides only suboptimal coronary protection early after stent implantation. Moreover, TAT precludes the advantages provided by the use of the latest and more potent P2Y12 inhibitors in ACS patients. Here, we aimed to simulate and compare the expected coronary, cardioembolic, and hemorrhagic outcomes offered by DAT, TAT, or modern dual antiplatelet therapy (DAPT) with aspirin plus one of the latest P2Y12 inhibitors in AF patients early after an ACS. The comparison of numbers needed to treat to prevent major adverse events with the various antithrombotic regimens suggests that AF-ACS patients at high ischemic and hemorrhagic risk and at moderately low embolic risk (CHA2DS2VASc score 2-4) might safely withhold anticoagulation after revascularization for one month taking advantage of a modern DAPT, with a favorable risk-to-benefit ratio. In conclusion, this strategy, not sufficiently addressed in recent European and North American guidelines or consensus documents, adds to the spectrum of treatment options in these difficult patients; it might be the best choice in a substantial number of patients; and should be prospectively tested in a randomized controlled trial.

Abstract
Background:
The impact of antithrombotic therapy on coagulation system activation after left atrial appendage closure (LAAC) remains unknown. This study sought to compare changes in coagulation markers associated with short-term oral anticoagulation (OAC) versus antiplatelet therapy (APT) following LAAC.
Methods:
Prospective study including 78 atrial fibrillation patients undergoing LAAC with the Watchman device. F1+2 (prothrombin fragment 1+2) and TAT (thrombin-antithrombin III) were assessed immediately before the procedure, and at 7, 30, and 180 days after LAAC.
Results:
Forty-eight patients were discharged on APT (dual: 31, single: 17) and 30 on OAC (direct anticoagulants: 26, vitamin K antagonists: 4), with no differences in baseline-procedural characteristics between groups except for higher spontaneous echocardiography contrast in the OAC group. OAC significantly reduced coagulation activation within 7 days post-LAAC compared with APT (23% [95% CI, 5%–41%] versus 82% [95% CI, 54%–111%] increase for F1+2,
P
=0.007; 52% [95% CI, 15%–89%] versus 183% [95% CI, 118%–248%] increase for TAT,
P
=0.048), with all patients in both groups progressively returning to baseline values at 30 and 180 days. Spontaneous echocardiography contrast pre-LAAC was associated with an enhanced activation of the coagulation system post-LAAC (144 [48–192] versus 52 [24–111] nmol/L,
P
=0.062 for F1+2; 299 [254–390] versus 78 [19–240] ng/mL,
P
=0.002 for TAT). Device-related thrombosis occurred in 5 patients (6.4%), and all of them were receiving APT at the time of transesophageal echocardiography (10.2% versus 0% if OAC at the time of transesophageal echocardiography,
P
=0.151). Patients with device thrombosis exhibited a greater coagulation activation 7 days post-LAAC (
P
=0.038 and
P
=0.108 for F1+2 and TAT, respectively).
Conclusions:
OAC (versus APT) was associated with a significant attenuation of coagulation system activation post-LAAC. Spontaneous echocardiography contrast pre-LAAC associated with enhanced coagulation activation post-LAAC, which in turn increased the risk of device thrombosis. These results highlight the urgent need for randomized trials comparing OAC versus APT post-LAAC.

Abstract
The Global Anticoagulant Registry in the Field-Atrial Fibrillation (GARFIELD-AF) examined real-world practice in a total of 57,149 (5069 retrospective, 52,080 prospective) patients with newly diagnosed AF at risk of stroke/systemic embolism, enrolled at over 1000 centers in 35 countries. It aimed to capture data on AF burden, patients' clinical profile, patterns of clinical practice and antithrombotic management, focusing on stroke/systemic embolism prevention, uptake of new oral anticoagulants, impact on death and bleeding. GARFIELD-AF set new standards for quality of data collection and analysis. A total of 36 peer-reviewed articles were already published and 73 abstracts presented at international congresses, covering treatment strategies, geographical variations in baseline risk and therapies, adverse outcomes and common comorbidities such as heart failure. A risk prediction tool as well as innovative observational studies and artificial intelligence methodologies are currently being developed by GARFIELD-AF researchers. Clinical Trial Registration: NCT01090362 (ClinicalTrials.gov).

Abstract
Triple anti-thrombotic therapy combining oral anticoagulation and dual anti-platelet therapy following percutaneous coronary intervention in patients with atrial fibrillation was considered as standard and recommended by guidelines. While bleeding risk is considerable with that approach, data for efficacy are scare. Several trials assessed the possibility of reducing anti-thrombotic treatment by mainly shortening the exposure to acetylsalicylic acid. Dropping one of the anti-platelet components might increase the risk of stent thrombosis, myocardial infarction or stroke. Despite that fear, the recent trials' primary endpoint was major and/or clinically-relevant non-major bleeding. We review data on major bleedings, intracranial bleedings and major adverse cardiovascular events from the published reports. We demonstrate that Non-Vitamin K oral anticoagulant (NOAC)-based strategies compared to VKA-based triple therapies significantly reduce the risk for TIMI-major bleedings by 39% and for intracranial bleedings by 66%, while they did not increase the risk for overall ischemic or embolic events. However, recent meta-analyses indicate an increased risk for stent thrombosis with less intense anti-thrombotic therapy. While the overall incidence rate for stent thrombosis is rather low, relative increases by about 30-60% are reported, but they did not translate into adverse clinical net-benefit ratios. This review highlights that using certain NOAC regimens proven effective for stroke prevention in AF can reduce the rate of bleeding without increasing ischemic or embolic events. Furthermore, additive ASA in triple anti-thrombotic regimens should be limited to 1 month and individual weighing of ischemic versus bleeding risk during the first 30 days seems to be reasonable.

Abstract
Routine determination of troponin levels is recommended for all patients with acute ischemic stroke. In 20-55% of these patients the troponin levels are elevated, which may be caused by ischemic as well as non-ischemic myocardial damage and particularly neurocardiogenic myocardial damage. In patients with acute ischemic stroke, the prevalence of previously unknown coronary heart disease is reported to be up to 27% and is prognostically relevant for these patients; however, relevant coronary stenoses are less frequently detected in stroke patients with troponin elevation compared to patients with non-ST elevation myocardial infarction. The risk of secondary intracerebral hemorrhage due to the necessity for dual platelet aggregation inhibition illustrates the challenging indication for invasive coronary diagnostics and revascularization. Therefore, a diagnostic work-up and interdisciplinary risk evaluation appropriate to the urgency are necessary in order to be able to determine a reasonable treatment approach with timing of the intervention, type and duration of blood thinning. In addition to conventional examination methods, multimodal cardiac imaging is increasingly used for this purpose. This review article aims to provide a pragmatic and clinically oriented approach to diagnostic and therapeutic procedures, taking into account the available evidence.

This study evaluated the benefit of dual therapy in reducing ischemic events in atrial fibrillation (AF) patients presenting with acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI). We searched PubMed, Cochrane Library, and ClinicalTrials.gov for randomized controlled trials (RCTs) comparing dual and triple therapies (oral anticoagulation plus aspirin and P2Y12 inhibitor) for AF patients with ACS or those undergoing PCI. The composite primary outcome included all-cause death, myocardial infarction (MI), stent thrombosis (ST), or stroke. Relative risk (RR) and the corresponding 95% confidence interval (CI) was used as the measure of effect size. Four RCTs with 10,969 patients were included. Dual therapy had a higher event rate of primary outcome than triple therapy (RR, 1.15; 95%CI, 1.03-1.28; P<0.0001). Dual therapy was associated with significantly higher MI risk, insignificantly higher ST risk, and significantly lower major bleeding risk than triple therapy (RR1.23, 95%CI 1.01-1.49, P = 0.036; RR 1.43, 95 %CI 0.98-2.09, P = 0.064; and RR0.58, 95%CI 0.45-0.76, P<0.0001, respectively). Dual antithrombotic therapy was associated with higher ischemic risk but lower major bleeding risk than triple therapy. The data suggest that antithrombotic regimens should be based on tradeoffs between ischemia and bleeding risk.

Antithrombotic treatment in patients with atrial fibrillation undergoing coronary angioplasty: rational convincement and supporting evidence. Eur J Intern Med 2020; 77:44-51.

Abstract
BACKGROUND The management of antithrombotic therapy in patients undergoing percutaneous coronary intervention (PCI) with an indication for long-term oral anticoagulant therapy (OAT) is still a matter of debate. We aim to evaluate the safety and the efficacy of dual therapy (DT) compared to triple therapy (TT) in this clinical setting. METHODS A study level meta-analysis and a review of randomized trials selected using PubMed, Embase, EBSCO, Cochrane database of systematic reviews, Web of Science, and abstract from major cardiology congresses. Six randomized trials with 12,156 patients evaluating the strategy of DT vs. TT in patients treated with PCI with indication for long-term OAT were included. RESULTS Patients treated with DT demonstrated a 45% relative reduction in the risk of TIMI major bleeding (1.71% vs. 2.99%; OR 0.55, 95% CI 0.41-0.71; P<0.0001) and TIMI minor bleeding compared to TT arm (4.67% vs 7.83%, OR 0.55 95% CI 0.39-0.78, P = 0.0007). All-cause mortality was similar in two arms (3.95% vs 3.77%, P = 0.92), as well as cardiovascular mortality (2.21% vs 2.19%, P = 0.97). DT was associated with a borderline increase of ST (1.02% vs 0.67%, P = 0.07). No significant differences were observed in occurrence of MI and stroke. CONCLUSIONS Our findings suggest that DT is safer than TT with regard to occurrence of major bleeding. DT with a direct oral anticoagulant plus clopidogrel at discharge could be effective in most patients, maintaining aspirin in periprocedural phase and as longer "tailored" treatment for patients at higher ischemic risk.

Abstract
BACKGROUND Because device-related thrombus (DRT) portends a poor prognosis after left atrial appendage closure with the Watchman device, surveillance transesophageal echocardiography (TEE) is recommended at 45 days and 1 year. However, oral anticoagulants are just discontinued at 45 days, rendering this early TEE unlikely to detect DRT. Indeed, DRT is most likely to occur after instituting aspirin monotherapy. OBJECTIVE The purpose of this study was to evaluate the alternative strategy of first TEE imaging (or computed tomography) at 4 months post-Watchman implantation. METHODS After Food and Drug Administration approval, consecutive patients undergoing Watchman implantation at 2 centers received TEE or CT at 4 months and 1 year, along with a truncated drug regimen: 6 weeks of an oral anticoagulant (or clopidogrel in a subset) plus aspirin, then 6 weeks of dual antiplatelet therapy, and finally aspirin monotherapy. RESULTS Of the 530-patient cohort (mean age 78.7±7.9 years; 65.5% (n = 347) male; CHA2DS2-VASc score 4.5±1.4), 465 patients (87.7%) received 4-month imaging: 83.0% (440 of 530) TEE and 4.7% (25 of 530) computed tomography. Over a median follow-up of 12 months, 16 ischemic strokes (ISs), 8 transient ischemic attacks, and 1 systemic embolization occurred. Importantly, no IS occurred between 45 days and 4 months; the sole transient ischemic attack in this period (at ∼2 months) occurred 1 week after transcatheter aortic valve replacement. DRT was detected in 2.4% (11 of 465) at 4 months and 0.9% (2 of 214) at 1 year. No IS, but 1 leg embolization, was observed after DRT detection. CONCLUSION Delaying the first imaging post-Watchman implantation to 4 months was associated with no IS between 45 days and 4 months, the "vulnerable" period of this follow-up strategy.

Abstract
Background:
Percutaneous left atrial appendage closure (LAAC) exposes to the risk of device thrombosis in patients with atrial fibrillation who frequently have a contraindication to full anticoagulation. Thereby, dual antiplatelet therapy (DAPT) is usually preferred. No randomized study has evaluated nonvitamin K antagonist oral anticoagulant after LAAC, and we decided to evaluate the efficacy and safety of reduced doses of rivaroxaban after LAAC.
Methods:
ADRIFT (Assessment of Dual Antiplatelet Therapy Versus Rivaroxaban in Atrial Fibrillation Patients Treated With Left Atrial Appendage Closure) is a multicenter, phase IIb study, which randomized 105 patients after successful LAAC to either rivaroxaban 10 mg (R
10
, n=37), rivaroxaban 15 mg (R
15
, n=35), or DAPT with aspirin 75 mg and clopidogrel 75 mg (n=33). The primary end point was thrombin generation (prothrombin fragments 1+2) measured 2 to 4 hours after drug intake, 10 days after treatment initiation. Thrombin-antithrombin complex, D-dimers, rivaroxaban concentrations were also measured at 10 days and 3 months. Clinical end points were evaluated at 3-month follow-up.
Results:
The primary end point was reduced with R
10
(179 pmol/L [interquartile range (IQR), 129–273],
P
<0.0001) and R
15
(163 pmol/L [IQR, 112–231],
P
<0.0001) as compared with DAPT (322 pmol/L [IQR, 218–528]). We observed no significant reduction of the primary end point between R
10
and R
15
while rivaroxaban concentrations increased significantly from 184 ng/mL (IQR, 127–290) with R
10
to 274 ng/mL (IQR, 192–377) with R
15
,
P
<0.0001. Thrombin-antithrombin complex and D-dimers were numerically lower with both rivaroxaban doses than with DAPT. These findings were all confirmed at 3 months. The clinical end points were not different between groups. A device thrombosis was noted in 2 patients assigned to DAPT.
Conclusions:
Thrombin generation measured after LAAC was lower in patients treated by reduced rivaroxaban doses than DAPT, supporting an alternative to the antithrombotic regimens currently used after LAAC and deserves further evaluation in larger studies.
