Immature platelets and cardiovascular events in patients with stable coronary artery disease
Platelets. 2023 Dec;34(1):2217960. doi: 10.1080/09537104.2023.2217960.ABSTRACTMany patients with coronary artery disease (CAD) have reduced the effect of aspirin, which may partly be explained by immature platelets. We aimed to investigate whether immature platelet markers can predict cardiovascular events in a large cohort of stable CAD patients. A total of 900 stable CAD patients were included and followed for a median of 3 years. We measured markers of immature platelets (platelet count, immature platelet count, immature platelet fraction, mean platelet volume, platelet distribution width, platelet mass, and thrombopoie...

Prevention of Venous Thromboembolism in Medical Patients with Thrombocytopenia or with Platelet Dysfunction: The Last 10 Years
Semin Thromb Hemost DOI: 10.1055/s-0043-1769013Current guideline recommendations for primary prophylaxis of venous thromboembolism (VTE) are based on randomized clinical trials that usually exclude subjects at a potentially high risk of bleeding complications. For this reason, no specific guideline is available for thromboprophylaxis in hospitalized patients with thrombocytopenia and/or platelet dysfunction. However, except in patients with absolute contraindications to anticoagulant drugs, antithrombotic prophylaxis should always be considered, for example, in hospitalized cancer patients with thrombocytopenia, especially...

The Applicability of Thromboelastography in Acute Ischemic Stroke: A Literature Review
This article aims to highlight the potential use of TEG in AIS patients by reviewing available studies. We conducted a literature review, including PubMed and Cochrane library databases. The following keywords were used to find relevant studies: thromboelastography, TEG, acute ischemic stroke, stroke, coagulopathy, antiplatelet, and anticoagulant treatment. We identified 142 papers and after abstract review, we included 24 studies in this report. TEG identified a hypercoagulable state in AIS patients represented by short R, K, and greater α angle in all papers included. Modification of TEG parameters induced by intravenou...

Clopidogrel monotherapy versus Aspirin monotherapy in patients with established cardiovascular disease: systematic review and meta-analysis
CONCLUSIONS: In patients with established cardiovascular disease, Clopidogrel was associated with a 17% relative-risk reduction for non-fatal MI, borderline decreased risk for MACE and similar risk for all-cause mortality, stroke and major bleeding compared to Aspirin.PMID:35577054 | DOI:10.1055/a-1853-2952

The PAR4 platelet thrombin receptor variant rs773902 does not impact the incidence of thrombotic or bleeding events in a healthy older population
CONCLUSIONS: This post-hoc analysis of a prospective cohort study suggests that, despite sensitizing platelet activation, the rs773902 PAR4 variant is not associated with thrombotic cardiovascular or bleeding events in a healthy older population.PMID:34852379 | DOI:10.1055/a-1711-1395

Serum thromboxane B2 but not soluble P-selectin levels identify ischemic stroke patients with persistent platelet reactivity while on aspirin therapy
Aspirin non-response due to persistent platelet reactivity has been associated with adverse vascular events. Light transmission aggregometry (LTA), the ‘gold standard’ for measuring the platelet response to aspirin therapy, is a cumbersome procedure and a simple and reliable alternative is required. Our aim was to explore whether serum thromboxane B2 (sTXB2) and soluble P-selectin can be used to identify patients who are at risk of increased pl atelet reactivity while on aspirin.

Clopidogrel increases risk of pneumonia compared with aspirin in acute ischemic minor stroke patients
AbstractAntiplatelet agents may increase the risk of infections via suppressing platelet-mediated immune response. Here we assessed the contribution of clopidogrel versus aspirin to the development of pneumonia during an acute ischemic stroke admission. A retrospective cohort study was conducted of acute ischemic stroke patients who were admitted to our hospital from 2015 to 2018. Included patients received uninterrupted clopidogrel or aspirin therapy and did not take other antiplatelet agents throughout their stay. The interest outcome was development of pneumonia after stroke. Conditional logistic regression model after ...

Benefit-risk profile of extended dual antiplatelet therapy beyond 1 year in patients with high risk of ischemic or bleeding events after PCI.
Authors: Wang HY, Gao RL, Xu B, Yang YJ, Yin D, Wang Y, Dou KF Abstract The benefits and harms of dual antiplatelet therapy (DAPT) continuation with aspirin and clopidogrel beyond 1 year after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation for high ischemic or bleeding risk patients remain unclear. All consecutive patients undergoing PCI were prospectively included in the Fuwai PCI Registry from January 2013 to December 2013. We evaluated 7521 patients who were at high risk for thrombotic or hemorrhagic complications and were events free at 1 year after the index procedure. "TWI...

Novel approaches to P2Y12 inhibition and aspirin dosing.
Authors: Parker WAE, Storey RF Abstract Aspirin and P2Y12 inhibitors remain commonly prescribed antiplatelet drugs in the treatment of atherothrombotic conditions. Despite established benefits of dual antiplatelet therapy (DAPT) in the setting of acute coronary syndromes, there remains residual ischemic risk in this group and the problem of bleeding complications is an ongoing issue. DAPT with aspirin and ticagrelor has now been studied in other patient groups such as those with concurrent diabetes and stable coronary artery disease, and those undergoing elective percutaneous coronary intervention (PCI). Recent tri...

Imbalance between Fibrin Clot Formation and Fibrinolysis Predicts Cardiovascular Events in Patients with Stable Coronary Artery Disease.
CONCLUSION:  We demonstrate that increased clot AUC predicts future cardiovascular events in stable CAD patients receiving aspirin monotherapy. PMID: 31733633 [PubMed - as supplied by publisher]
