AIMS: Polymer-free biolimus-eluting stents (PF-BES) have been shown superior to bare metal stents in high bleeding risk (HBR) patients treated with 1-month dual antiplatelet therapy (DAPT). However, limited evidence is available on PF-BES in non-HBR patients. We aim to evaluate the safety and efficacy of PF-BES in all-comer patients undergoing percutaneous coronary interventions (PCI). METHODS AND RESULTS: Patients with stable coronary artery disease or acute coronary syndromes (ACS) undergoing PCI with PF-BES in routine clinical practice were included in a multicenter, prospective registry...

In recent years, the issues of choice of an agent for dual antiplatelet therapy (DAPT) as well as timing of initiation and duration of DAPT in patients with acute coronary syndrome (ACS) have been actively discussed. In this article we present data of major randomized trials of clopidogrel and novel P2Y12 inhibitors - prasugrel, ticagrelor, cangrelor - assessing strategy of administration of antiaggregants in patients with ACS before coronary angiography / percutaneous coronary intervention. The article also contains analysis of differences between recommendations of the European Society of Cardiology and American College of Cardiology/American Heart Association on therapy with oral P2Y12 inhibitors in the management of patients with ACS...

OBJECTIVE: to determine impact of different laboratory and genetic factors on high on-treatment platelet reactivity (HOPR) during dual antiplatelet therapy (DAPT). METHODS: We included in this study 94 patients with stable ischemic heart disease (mean age 59±9.67 years). All patients underwent elective PCI with implantation of drug eluting stents at the background of dual antiplatelet therapy (DAPT) with aspirin and clopidogrel. Platelet reactivity was assessed using light transmission aggregometry with 5 μmol/L ADP (LTA 5ADP) and VerifyNow assay before PCI...

Dual antiplatelet therapy (DAPT) has been the cornerstone of antithrombotic management for patients undergoing percutaneous coronary intervention (PCI). Despite low-quality evidence, triple antithrombotic therapy involving acetylsalicylic acid, clopidogrel and warfarin or non-vitamin K antagonist oral anticoagulant (NOAC) has been recommended in patients with concomitant atrial fibrillation undergoing PCI, who require long-term oral anticoagulation, although such strategy is associated with a substantially increased risk of bleeding compared with DAPT...

Notch‑3 is a receptor of the Notch signaling pathway and plays an important role in regulating self‑renewal, differentiation and apoptosis in cancer cells. Overexpression of Notch‑3 has been proved to be associated with resistance to gemcitabine (GEM) and poor patient prognosis for various malignant tumors. In the present study, two non‑small cell lung cancer (NSCLC) cell lines, H1299 and A549, were induced with GEM for two months and then were treated with various concentrations of a Notch signaling blocker, N‑[N‑(3,5‑difluorophenacetyl)‑L‑alanyl]‑S‑phenylglycine t‑butyl ester (DAPT), with the goal of reducing expression of Notch intracellular domain 3 (NICD3)...

Aim: Combined use of herbal medicines in patients underwent dual antiplatelet therapy (DAPT) might cause bleeding or thrombosis because herbal medicines with anti-platelet activities may exhibit interactions with DAPT. In this study, we tried to use a feedback system control (FSC) optimization technique to optimize dose strategy and clarify possible interactions in combined use of DAPT and herbal medicines. Methods: Herbal medicines with reported anti-platelet activities were selected by searching related references in Pubmed...

Current guidelines recommend dual-antiplatelet therapy (DAPT) after transcatheter aortic valve implantation (TAVI), although some studies suggest mono-antiplatelet therapy is equally efficacious with an improved safety profile. We performed a meta-analysis of studies comparing DAPT with mono-antiplatelet therapy after TAVI. Study quality and heterogeneity were assessed using Jadad score, Newcastle-Ottawa Scale, and Cochran's Q statistics. Mantel-Haenszel odds ratios (ORs) were calculated using fixed effect models as the primary analysis...

BACKGROUND: The optimal duration of dual antiplatelet therapy (DAPT) for preventing delayed thromboembolic events (DTEs) remains unclear. We aimed to determine whether longer DAPT provides improved protection against delayed DTEs. METHODS: This retrospective cohort study included 507 stent-assisted coil embolization procedures using a single stent for unruptured intracranial aneurysms. We performed coarsened exact matching according to the duration of maintenance DAPT...

BACKGROUND: Acute coronary syndromes (ACS) represent a context of higher thrombotic risk, where larger advantages have been achieved by the administration of dual antiplatelet therapy (DAPT). However, the indication of 1 year DAPT after coronary angioplasty for ACS has been supported by an outdated randomized trial (PCI-CURE). In addition, the initial fear of late thrombotic events emerged with first generation drug-eluting stents (DES), that suggested the need of a prolonged DAPT prescription, has been completely overcome by the recent technological evolution of DES, that have shown faster re-endothelization and lower rates of late thrombotic complications...

BACKGROUND: Dual antiplatelet therapy (DAPT) is recommended in patients receiving drug-eluting stents (DES). However, bleeding risk should be weighed against ischemic risk. Utility of GRACE risk score and ACUITY-HORIZONS bleeding risk score was assessed in patients with acute myocardial infarction (MI) according to use of P2Y12 blocker. METHODS: From the Korea Acute Myocardial Infarction Registry-National Institute of Health database, 7791 patients with acute MI receiving DES were divided into ticagrelor (n=1554) and clopidogrel (n=6237) groups...

To prevent early neurological worsening or recurrence in stroke patients with intracranial arterial stenosis or branch atheromatous disease, aggressive antithrombotic therapy, such as dual antiplatelet therapy (DAPT) with or without anticoagulant therapy, is warranted. Such an aggressive antithrombotic therapy, however, may increase the bleeding risk. We studied the risks of DAPT with the anticoagulant argatroban in patients with acute ischemic stroke or transient ischemic attack (TIA). Between October 2011 and September 2015, 341 patients with stroke or TIA, who received DAPT with argatroban within 48 hours after onset, were retrospectively studied...

Ischemic brain injury is an important cause for seizure. Mild hypothermia of the brain or the whole body is an effective way to remit the post-stroke seizure. Our previous study revealed an implication of Notch 1 and 2 in the post-stroke seizure. This study further investigated the involvement of Notch 3 and 4 in post-stroke seizure and the effect of mild hypothermia on these two factors. A global cerebral ischemia (GCI) model was conducted in Sprague Dawley rats. Seizure activity was evaluated by the frequency of seizure attacks, seizure severity scores, and seizure discharges...

OBJECTIVES: Perioperative myocardial infarction (MI) after coronary artery bypass graft surgery (CABG) has been associated with adverse outcome. Whether perioperative MI should be treated with dual antiplatelet therapy (DAPT) is unknown. We compared the effect of DAPT versus aspirin alone on short-term outcomes among patients with perioperative MI following CABG. METHODS: We used data from 3 clinical trials that enrolled patients undergoing isolated CABG: PREVENT IV (2002-2003), MEND-CABG II (2004-2005), and RED-CABG (2009-2010) (n = 9117)...

Air-liquid interface (ALI) cultures of mouse tracheal epithelial cells (MTEC) are a well-established model to study airway epithelial cells, but current methods require large numbers of animals which is unwanted in view of the 3R principle and introduces variation. Moreover, stringent breeding schemes are frequently needed to generate sufficient numbers of genetically modified animals. Current protocols do not incorporate expansion of MTEC, and therefore we developed a protocol to expand MTEC while maintaining their differentiation capacity...

REVIEW
M S Jacobs, R G Tieleman
Patients with atrial fibrillation who undergo a coronary intervention are eligible for both anticoagulation and (dual) antiplatelet therapy ((D)APT). An optimal balance has to be found to reduce the thromboembolic risk (i.e. stroke, systemic embolism and myocardial infarction) and to minimise the increased risk of bleeding with concomitant use of an anticoagulant and (D)APT. Owing to a lack of evidence, the guideline recommendations are predominantly based on expert opinion. Current evidence indicates that the combination of a non-vitamin K oral anticoagulant (NOAC) and clopidogrel is safer than vitamin-K oral antagonists plus DAPT, which increases the risk of bleeding, without clear advantages in regard to efficacy...

NOTCH signaling is required for the arterial specification and formation of hematopoietic stem cells (HSCs) and lympho-myeloid progenitors in the embryonic aorta-gonad-mesonephros region and extraembryonic vasculature from a distinct lineage of vascular endothelial cells with hemogenic potential. However, the role of NOTCH signaling in hemogenic endothelium (HE) specification from human pluripotent stem cell (hPSC) has not been studied. Here, using a chemically defined hPSC differentiation system combined with the use of DLL1-Fc and DAPT to manipulate NOTCH, we discover that NOTCH activation in hPSC-derived immature HE progenitors leads to formation of CD144+ CD43- CD73- DLL4+ Runx1 + 23-GFP+ arterial-type HE, which requires NOTCH signaling to undergo endothelial-to-hematopoietic transition and produce definitive lympho-myeloid and erythroid cells...

Jessica M Lewis, James J Nawarskas
Much debate has centered on whether or not the standard 12 month duration of dual antiplatelet therapy (DAPT) is still necessary post-percutaneous coronary intervention (PCI) given recent improvements in stent technology. The benefits of shorter (3-6 months) durations of DAPT include a potential lower risk for bleeding and less patient drug cost and pill burden. While randomized clinical trials have shown non-inferiority for shorter versus longer DAPT regimens in many regards, some endpoints (e.g. myocardial infarction) may still occur less frequently with longer DAPT regimens, particularly in higher risk populations (e...
