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 ...

Platelet-related biomarkers and their response to inhibition with aspirin and p2y 12 -receptor antagonists in patients with acute coronary syndrome
AbstractThe PLATelet inhibition and patient Outcomes (PLATO) trial showed that treatment with ticagrelor reduced the rate of death due to vascular causes, myocardial infarction and stroke when compared to clopidogrel in patients with ST-elevation or non-ST-elevation acute coronary syndrome (ACS). While the comparative benefit of ticagrelor over clopidogrel increased over time, event rates accrued in both groups during the study period. The purpose of our biomarker-based exploratory analysis was to determine whether long-term platelet inhibition may be associated with plateletadaptation. A sample of 4000 participants from t...

High residual platelet reactivity (HRPR) for adenosine diphosphate (ADP) stimuli is a determinant factor for long-term outcomes in acute ischemic stroke with anti-platelet agents: The meaning of HRPR after ADP might be more prominent in large atherosclerotic infarction than other subtypes of AIS
In this study, we evaluated the influences of HRPR after ADP stimuli on the 1-year incidence of recurrent cardiovascular events and mortality in AIS with APAs. We conducted an observational, referral center cohort study on 968 AIS patients with APAs from January 2010 to December 2013 who were evaluated using optical platelet aggregometry (OPA). All patients received the dual APA combination of aspirin and clopidogrel or aspirin alone. We evaluated their platelet function 5 days after hospital admission using OPA. HRPR after ADP stimuli was defined as platelet aggregation of 70 % or greater according to OPA after 10 µM ...

Switching from clopidogrel to prasugrel in patients having coronary stent implantation
Abstract There are very few clinical data concerning the safety of switching from clopidogrel to prasugrel in patients undergoing coronary stenting. However, in the daily activity, clinicians face the decision of switching patients at high-risk of thrombotic events from clopidogrel to prasugrel. Thus, we sought to evaluate clinical events in patients undergoing coronary stent implantation and prasugrel therapy with (SWITCH group) or without (NAÏVE group) prior clopidogrel therapy. A total of 454 patients with stable or unstable coronary artery disease, aged 70 ± 10 years, underwent non-emergent stent implant...
