Background: This systematic review examines the occurrence and implications of resistance to primary antiplatelet agents, aspirin and clopidogrel, often utilised in patients undergoing coronary artery bypass grafting (CABG), alongside the methodologies for assessment of such resistance.
Methods: An extensive literature search across various databases such as PubMed, MEDLINE via Ovid, Embase, and Cochrane CENTRAL until May 2024 was conducted to identify studies evaluating antiplatelet resistance in on-pump and off-pump CABG patients. Following quality assessment, only high-quality studies were incorporated into this review.
Results: This review included 19 studies with 3,915 patients, four of which were randomised controlled trials and 15 were observational studies. Aspirin resistance incidence ranged from 11.0% to 51.5%, while clopidogrel resistance was 22%. Antiplatelet resistance, assessed through a wide variety of methods, was associated with a 13 times increase in the risk of vein graft occlusion and increased rates of mortality, myocardial infarction, and target vessel revascularisation in the case of clopidogrel resistance. The effect of cardiopulmonary bypass on antiplatelet resistance remains ambiguous.
Conclusion: The academic literature lacks a standardised definition for antiplatelet resistance. Assessment methodologies greatly vary, leading to noninterchangeable outcomes. While aspirin resistance has a conflicting overall significant impact on adverse outcomes, clopidogrel resistance correlates with poorer clinical outcomes.

Introduction: The demographics of the United States (US) are evolving as time progresses. The geriatric population is growing, with many elderly people dealing with mental health issues. Major depressive episodes affect 1 to 5 percent of those aged 65 years or older, which emphasizes the importance of addressing mental health concerns in this populace.

Monitoring platelet aggregation is crucial for predicting thrombotic diseases and identifying the risk of bleeding or resistance to antiplatelet drugs. This study developed a microfluidic device to measure platelet activation with high sensitivity. By controlling exposure time through repeated reinjections, the device enables the detection of subtle changes in platelet activity influenced by lifestyle factors, such as alcohol consumption.

Coronary atherosclerosis (or coronary heart disease [CHD]) is a common cardiovascular disease that seriously damages human health. Percutaneous coronary stent implantation represents the primary treatment option for severe CHD in clinical practice; meanwhile, dual antiplatelet therapy (DAPT) is widely used to reduce the risk of postoperative thrombosis. Although the mechanisms of action of the two most commonly used antiplatelet drugs, aspirin and clopidogrel, remain unclear, clinical studies have shown that some patients are susceptible to stent thrombosis-antiplatelet resistance (high on-treatment platelet reactivity [HTPR])-despite using these drugs.

Objective: Lower extremity arterial disease (LEAD) is a prevalent condition that produces a significant burden on health care systems. Patients with LEAD have an increased risk of major adverse cardiovascular events as well as major adverse limb events. Despite significant variation in guidance on antiplatelet therapy for LEAD worldwide, many governing bodies recommend clopidogrel as the preferred single anti-platelet agent.

After coronary drug-eluting stent (DES) implantation, dual antiplatelet therapy (DAPT, usually aspirin in combination with a P2Y12 inhibitor) is necessary. However, older patients are prone to aspirin intolerance or resistance. Indobufen has been reported as an ideal alternative to aspirin.
