Prolonged antithrombotic treatment after de-escalation of dual antiplatelet therapy in patients after acute coronary syndrome - which strategy should be applied? The ELECTRA-SIRIO 2 investigators standpoint.

De-escalation of dual antiplatelet (DAPT) intensity may be considered in patients with high risk of bleeding after acute coronary syndrome. Some high risk patients after de-escalation may require antithrombotic therapy prolonged over 12 months. With the current guideline recommended strategies, there are some doubts and uncertainties with respect to the transition period.

International Consensus Statement on Platelet Function and Genetic Testing in Percutaneous Coronary Intervention: 2024 Update.

Current evidence indicates that dual antiplatelet therapy with aspirin plus a P2Y inhibitor is essential for the prevention of thrombotic events after percutaneous coronary interventions. However, dual antiplatelet therapy is associated with increased bleeding which may outweigh the benefits. This has set the foundations for customizing antiplatelet treatments to the individual patient.

Can CYP2C19 genotyping improve antiplatelet therapy efficacy in real-life practice? Recent advances.

Clopidogrel remains the most widely used P2Y12 receptor inhibitor worldwide and is often used in combination with aspirin for secondary prevention in patients with arterial disease. The drug is associated with a wide variation in responses, with one in 3 patients exhibiting little or no inhibition of adenosine diphosphate-induced platelet aggregation. It is a prodrug that is mainly metabolized by hepatic cytochrome P450 (CYP) 2C19.

New interest in fibrinogen as an ischemic risk factor.

Platelet-fibrin clot formation is a key process in acute arterial thrombosis. The relationship between thrombin-induced platelet-fibrin clot strength (P-FCS) and fibrinogen levels in patients with cardiovascular disease (CVD) and COVID-19 has not been studied. In thhe current study, the contribution of fibrinogen to P-FCS has been explored in healthy subjects (n=157), patients hospitalized with COVID-19 (n=116), and patients with CVD (n=93) using thrombelastography (TEG 6s) with citrate cartridge.

Long-term prognostic implications of brachial-ankle pulse wave velocity in patients undergoing percutaneous coronary intervention.

Objective: The long-term clinical effect of arterial stiffness in high-risk disease entities remains unclear. The prognostic implications of brachial-ankle pulse wave velocity (baPWV) were assessed using a real-world registry that included patients who underwent percutaneous coronary intervention (PCI).

Methods: Arterial stiffness was measured using baPWV before discharge.

Platelet-fibrin clot strength and platelet reactivity predicting cardiovascular events after percutaneous coronary interventions.

Background And Aims: Platelet-fibrin clot strength (PFCS) is linked to major adverse cardiovascular event (MACE) risk. However, the association between PFCS and platelet reactivity and their prognostic implication remains uncertain in patients undergoing percutaneous coronary intervention (PCI).

Methods: In PCI-treated patients (n = 2512) from registry data from January 2010 to November 2018 in South Korea, PFCS using thromboelastography and platelet reactivity using VerifyNow were measured.

Efficacy and Safety of P2Y monotherapy vs standard DAPT in patients undergoing percutaneous coronary intervention: meta-analysis of randomized trials.

Background: Debates persist regarding the optimal duration of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in coronary artery disease (CAD). Recent trials have introduced a novel approach involving P2Y12 inhibitor monotherapy with ticagrelor or clopidogrel, after a short DAPT. However, the effectiveness and safety of this strategy remains to be established.

P2Y12 Inhibitor Monotherapy After Short-Term Dual Antiplatelet Therapy in Acute Coronary Syndrome.

Recent studies have shown similar safety and efficacy of short-term dual antiplatelet therapy (DAPT) followed by P2Y12 inhibitor (P2Y12i) monotherapy when compared with standard DAPT. However, the optimal DAPT duration and regimen in acute coronary syndrome (ACS) patients who underwent percutaneous coronary intervention is still unclear. Online databases were searched for randomized controlled trials evaluating P2Y12i monotherapy after short DAPT (≤3 months) versus standard DAPT (≥12 months) in ACS patients.

Systemic hypertension with VEGFR inhibitor (axitinib) therapy in cancer patients: A meta-analysis and systematic review of randomized controlled trials.

Vascular endothelial growth factor receptor inhibitors (VEGFRi), namely axitinib, are commonly used chemotherapeutic agents in patients with cancer; however, this medication has a significant cardiovascular side effect profile, such as high-grade hypertension. We performed this updated meta-analysis of RCTs to compile cardiovascular adverse events, such as all-grade and high-grade (>3) hypertension, the risk for thrombosis (DVT and PE), and peripheral edema. A systematic search was performed on PubMed, Cochrane, and Embase from inception until October 2023 for studies using axitinib to treat various cancers.

Development of a routine bedside CYP2C19 genotype assessment program for antiplatelet therapy guidance in a community hospital catheterization laboratory.

Genotype based personalized antiplatelet therapy in the setting of percutaneous coronary intervention (PCI) has been studied in clinical trials. Despite the demonstrated risk associated with CYP2C19 loss-of-function (LoF) carriage in clopidogrel-treated PCI patients, real-world implementation of genotyping for PCI has been low. The goal of the current study was to provide CYP2C19 genotype information to the interventionalist prior to the completion of the catheterization to facilitate immediate personalized antiplatelet therapy.

Cardiovascular Outcomes With Empagliflozin and Dapagliflozin in Patients Without Diabetes.

Although the cardiovascular (CV) benefits of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in patients with diabetes mellitus (DM) are well known, their effects in patients without DM continue to be explored. We provide a meta-analysis of the available evidence. Online databases were searched for randomized controlled trials (RCTs) comparing SGLT2i to placebo/control in patients without DM.

Safety and efficacy of glucagon-like peptide-1 receptor agonists on cardiovascular events in overweight or obese non-diabetic patients.

Background: Randomized controlled trials (RCTs) have shown variable cardiovascular (CV) outcomes in overweight or obese patients without diabetes mellitus (DM) who are treated with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) vs. placebo. We conducted a meta-analysis of the available studies.

Utility of VerifyNow to assess the immediate pharmacodynamic response of chewed and swallowed aspirin: comparison with aggregometry.

VerifyNow (VN) test is a less laborious method to assess pharmacodynamics (PD) compared to light transmittance aggregometry (LTA). VN assay has not been used to study the immediate PD effects of acetylsalicylic acid (ASA). Ten healthy volunteers were randomly assigned to a single 162 or 650 mg dose of chewed and swallowed ASA.

An overview of the utility of prasugrel hydrochloride as a treatment option for ischemic stroke.

Introduction: Prasugrel, a potent P2Y receptor inhibitor, is not currently recommended in patients with stroke due to a higher rate of recurrent stroke. Prasugrel was associated with comparable efficacy to clopidogrel in reducing the risk of ischemic stroke in a recent phase III study.

Areas Covered: The authors provide an overview of the potential role of prasugrel in the management of ischemic stroke.

Low-Dose Aspirin for Primary Prevention of Cardiovascular Events Comparing East Asians With Westerners: A Meta-Analysis.

Background: East Asians have shown different risk profiles for both thrombophilia and bleeding than Western counterparts.

Objectives: The authors sought to evaluate the effect of low-dose aspirin for primary prevention between these populations.

Methods: We searched randomized clinical trials (RCTs) for intervention with low-dose aspirin (≤100 mg once daily) in participants without symptomatic cardiovascular disease until December 31, 2021.

Meta-Analysis of the Performance of AI-Driven ECG Interpretation in the Diagnosis of Valvular Heart Diseases.

Valvular heart diseases (VHDs) significantly impact morbidity and mortality rates worldwide. Early diagnosis improves patient outcomes. Artificial intelligence (AI) applied to electrocardiogram (ECG) interpretation presents a promising approach for early VHD detection.
