BACKGROUND: Current guidelines recommend dual antiplatelet therapy (DAPT) of aspirin plus a P2Y12 inhibitor for at least 12 months after implantation of drug-eluting stents (DES) in patients with acute coronary syndrome. However, available data about the optimal duration of DAPT in patients with acute coronary syndrome undergoing percutaneous coronary intervention are scant. We aimed to investigate whether a 6-month duration of DAPT would be non-inferior to the conventional 12-month or longer duration of DAPT in this population...

BACKGROUND: Dual antiplatelet therapy (DAPT) remains the cornerstone therapy in the prevention of ischaemic events following drug-eluting stent (DES) implantation. Mandatory duration of DAPT after DES however, is a matter of debate. We aimed to evaluate safety and efficacy of short-term (up to 6 months) versus long-term (12 months) DAPT after DES implantation. METHODS: We searched PubMed, EMBASE, Cochrane databases, and international meetings for randomised clinical trials (RCTs) comparing short with long DAPT...

Antiplatelet therapy (APT) has become an important tool in the treatment and prevention of atherosclerotic events, particularly those associated with coronary artery disease. A large evidence base has evolved regarding the relationship between APT prescription in various clinical contexts and risk/benefit relationships. The Guidelines Committee of the Canadian Cardiovascular Society and Canadian Association of Interventional Cardiology publishes regular updates of its recommendations, taking into consideration the most recent clinical evidence...

OBJECTIVES: The aim of this study was to determine predictors of very late stent thrombosis (VLST; >1 year after stenting), and to evaluate whether addition of these predictors to the dual antiplatelet therapy (DAPT) score would improve the ability to identify patients at high risk of VLST who might benefit from DAPT. BACKGROUND: VLST is a severe complication of percutaneous coronary intervention (PCI). Extended knowledge about the predictors of VLST is needed to prevent this life-threatening complication...

Optimal duration of dual antiplatelet therapy (DAPT) after stent implantation is uncertain. Some patients have an extended risk of thrombotic complications including that of very late stent thrombosis after cessation of recommended course of DAPT (6-12 months). On the other hand, there is a real risk of bleeding on DAPT. In this review, we present and discuss results of clinical trials of long-term DAPT and data of their meta-analyses. The review also contains consideration of some aspects of new AHA/ACC recommendations (2016) on duration of DAPT...

Dual antiplatelet therapy (DAPT) with thienopyridine and aspirin is the standard care for the prevention of stent thrombosis. However, the optimal duration and effect of the duration of DAPT on intra-stent thrombus (IS-Th) formation are unknown. The NIPPON study (Nobori Dual Antiplatelet Therapy as Appropriate Duration) was an open label, randomized multicenter, assessor-blinded, trial designed to demonstrate the non-inferiority of shorter (6-month) DAPT to prolonged (18-month) DAPT, after biolimus A9 eluting stent implantation in 3773 patients at 130 sites in Japan...

BACKGROUND: Device-related thrombus (DRT) after left atrial appendage occlusion is a worrisome finding with little knowledge about when to expect it and how to prevent it. This study sought to investigate correlates of DRT after left atrial appendage occlusion, its time of diagnosis, and particularly, association with postimplantation dual antiplatelet therapy duration. METHODS AND RESULTS: Consecutive patients (n=102) after left atrial appendage occlusion with AMPLATZER Cardiac Plug/Amulet (n=59) or WATCHMAN (n=43) were included in a prospective registry (October 2011-May 2016)...

BACKGROUND: The use of short-duration dual antiplatelet therapy (DAPT) remains controversial. To investigate efficacy and safety of short-duration DAPT, we performed a detailed comparison of intra-stent conditions by optical coherence tomography (OCT) after second-generation drug-eluting stent implantation with short-term and standard DAPT. METHODS AND RESULTS: Eighty-two consecutive patients with stable angina pectoris who received Resolute zotarolimus-eluting stents (R-ZESs; Medtronic Cardiovascular, Santa Rosa, CA, USA) were enrolled...

Transcatheter aortic valve implantation (TAVI) carries a significant thromboembolic and concomitant bleeding risk, not only during the procedure but also during the periprocedural period. Many issues concerning optimal antithrombotic therapy after TAVI are still under debate. In the present review, we aimed to identify all relevant studies evaluating antithrombotic therapeutic strategies in relation to clinical outcomes after the procedure. Four randomized control trials (RCT) were identified analyzing the post-TAVI antithrombotic strategy with all of them utilizing aspirin lifelong plus clopidogrel for 3-6 months...

Determining the optimal duration of dual antiplatelet therapy (DAPT) following percutaneous coronary intervention is a complex decision. Randomized controlled trials have shown that while shorter durations of DAPT may lower the risk of bleeding, longer durations of DAPT can reduce the risk of late stent thrombosis and ischemia-related events. In this review article, we will discuss the current guidelines, review contemporary trial data that have evaluated short and extended durations of DAPT, and address common clinical questions...

Objective: International guidelines recommend the use of dual antiplatelet therapy (DAPT) after transcatheter aortic valve implantation (TAVI). The recommended duration of DAPT varies between guidelines. In this two-part study, we (1) performed a structured survey of 45 TAVI centres from around the world to determine if there is consensus among clinicians regarding antiplatelet therapy after TAVI; and then (2) performed a systematic review of all suitable studies (randomised controlled trials (RCTs) and registries) to determine if aspirin monotherapy can be used instead of DAPT...

RATIONALE: Among atrial fibrillation patients with high risk of bleeding, left atrial appendage occlusion has emerged as an alternative to long-term oral anticoagulation therapy for stroke prevention. Device-related thrombus remains a major concern because it may result in recurrent embolic events. To date, there is no consensus on the optimal method of treating device-related-thrombus. PATIENT CONCERNS: A 78-year-old man with atrial fibrillation had an episode of intracranial hemorrhage while taking warfarin...

The novel dual-therapy COMBO stent aims to promote vessel healing after percutaneous coronary intervention (PCI) in patients with coronary artery disease. The pro-healing technique consists of an anti-CD34+ antibody layer that attracts circulating endothelial progenitor cells (EPCs), which bind to the stent surface and allow rapid endothelialization by differentiation of the EPCs into normal endothelial cells. The COMBO stent combines this pro-healing technique with an abluminal drug elution of sirolimus. The promise of this dual-therapy stent is that it may safely allow a shortened duration of dual-antiplatelet therapy (DAPT) after stent placement...

Atrial fibrillation (AF) is a common arrhythmia that increases in prevalence with advancing age and in patients with coronary artery disease, revascularization, particularly with percutaneous coronary intervention (PCI), is also common. Both disease states have thrombosis as a core pathophysiologic process which requires treatment - low sheer stress thrombi in AF and intracoronary high sheer stress thrombi in PCI. For the 10-20% of patients who have both AF and undergo PCI, preventing thrombotic complications will require inhibition of both processes requiring simultaneous use of anticoagulation and antiplatelet therapy...

BACKGROUND: Diabetes mellitus is known to be associated with worse clinical outcomes in patients with coronary artery disease (CAD) undergoing percutaneous coronary interventions (PCI) with drug-eluting stents (DES). Defining the optimal duration of dual antiplatelet therapy (DAPT) after DES implantation is still under debate. The objective of this subgroup analysis of the all-comers ISAR 2000 registry was to assess the safety and efficacy of a short DAPT (<6 month) versus a longer DAPT (>6 month) in patients with diabetes electively treated with the polymer-free sirolimus-coated ultrathin strut drug-eluting stent (PF-SES)...

PURPOSE OF REVIEW: Coronary heart disease (CHD) and atrial fibrillation (AF) are among the most common cardiovascular diseases. A significant proportion of patients have both CHD and AF and are at increased risk for thrombotic complications. Current therapy for CHD and AF includes antiplatelet and anticoagulant medications, respectively. Patients with concurrent CHD and AF may be prescribed dual antiplatelet therapy (DAPT) in addition to anticoagulation, which increases their bleeding risk...
