AI Article Synopsis

  • ADP is essential for blood clot formation, and its inhibition can help prevent heart issues in patients with acute coronary syndrome or those undergoing certain heart procedures.
  • Thienopyridines are drugs that target and block the P2Y12 receptor to reduce platelet production, and are usually taken alongside aspirin for effectiveness.
  • Concerns exist regarding potential negative interactions between thienopyridines (like clopidogrel) and proton pump inhibitors, which may lessen their effectiveness and increase heart event risks.

Article Abstract

Adenosin diphospat (ADP) plays a crucial role in thrombus formation. Therefore its inhibition can control excess platelet generation to prevent cardiovascular events in patients with acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI). One of ADP's target receptors, P2Y12 has a limited tissue distribution and is therefore an attractive pharmacological target. Thienopyridines are class of drugs that specifically and irreversibly inhibit the P2Y12 receptor. Three generations exist and in most patients, they are administered in combination with aspirin. Because of possible gastro-intestinal toxicity, a proton pump inhibitor (PPI) is often concomitantly prescribed. However, several studies suspect an interaction between thienopyridines (in particular with clopidogrel) and PPIs which decreases the inhibition of platelet formation and thus enhances the risk for cardiac events. In this review, a concise overview of pharmacokinetic and pharmacodynamic properties of all thienopyridines is given and a critical discussion of the presumed interaction with PPIs is provided.

Dual Antiplatelet Treatment up to 72 Hours After Ischemic Stroke Stratified by Risk Profile: A Post Hoc Analysis.

Stroke

Department of Neurology, Beijing Tiantan Hospital, Capital Medical University, China (Y.Z., X.W., Y.G., W.C., H.Y., T.W., Y.Y., Q.Z., M.W., J.J., C.W., Yongjun Wang, Yilong Wang, Y.P.).

Background: Risk profile of recurrence may influence the effect of antiplatelet therapy. This study aimed to evaluate the efficacy and safety of clopidogrel-aspirin initiated within 72 hours after symptom onset for acute mild stroke or high-risk transient ischemic attack stratified by risk profile.

Methods: This is a secondary post hoc analysis of the INSPIRES (Intensive Statin and Antiplatelet Therapy for Acute High-risk Intracranial or Extracranial Atherosclerosis) randomized clinical trial that enrolled patients 35 to 80 years old with acute mild ischemic stroke or high-risk transient ischemic attack between 2018 and 2022.

Background: Clopidogrel resistance (CR) increases the risk of atherothrombotic events. Emerging evidence suggests that circRNAs may influence pharmacodynamic responses to clopidogrel.

Methods: A total of 25 CR and 25 non-clopidogrel resistance (NCR) patients were enrolled.

Calcium channel blockers (CCBs) are frequently co-administered with clopidogrel in cardiovascular disease. Although an inhibitory drug interaction exists between them, comprehensive large-scale studies for its validation are lacking. We investigated interactions between CCBs and clopidogrel using a large-scale national registry of patients who underwent percutaneous coronary intervention (PCI).

Efficacy of dual antiplatelet therapy after ischemic stroke according to hsCRP levels and CYP2C19 genotype.

Am Heart J

Department of Neurology, Beijing Tiantan Hospital, Capital Medical University, Beijing, China; China National Clinical Research Center for Neurological Diseases, Beijing, China; and Center of Stroke, Beijing Institute for Brain Disorders, Beijing, China. Electronic address:

Background: Both high-sensitive C-reactive protein (hsCRP) and CYP2C19 genotypes are independent predictors of clinical outcomes after ischemic stroke. We aim to evaluate the association of CYP2C19 loss-of-function alleles (LoFA) carrying status with the effects of dual/single antiplatelet therapy at different hsCRP levels using the CHANCE trial.

Methods: Subjects with both of CYP2C19 major alleles information (*2, *3, and *17) and hsCRP measurements were enrolled from the prespecified subgroup.

Increased platelet activity is a risk factor of thrombotic events in cardiovascular patients. We studied the relationship between platelet function, platelet size, and the content of reticulated platelets (RP) in patients with coronary heart disease (CHD, n = 55) and acute coronary syndrome (ACS, n = 95) receiving acetylsalicylic acid + clopidogrel or ticagrelor, respectively. The control group consisted of patients with risk factors for CHD, but with no CHD/ACS and free of antiplatelet drugs (n = 66).
