The benefit of early initiation of statin therapy during acute coronary syndromes slowly accrues over time so that a survival advantage is seen around 24 months. Relatively few patients need to be treated to prevent one death over this time period. Furthermore, this approach significantly reduces unstable angina and the need for revascularization.
Clopidogrel bisulfate is a potent adenosine diphosphate receptor blocker that irreversibly inhibits platelet aggregation by preventing the activation of the glycoprotein IIb/IIIa pathway. This helps to prevent thrombus formation and resultant ischemic or thrombotic complications. Clopidogrel was proven to be superior to aspirin in the treatment of atherothrombotic diseases. Clopidogrel plus aspirin, known as dual antiplatelet therapy, is highly effective in patients with acute coronary syndromes or undergoing percutaneous coronary intervention. There is no apparent benefit of dual antiplatelet therapy in primary prevention. In this article, we review the benefits of clopidogrel as an antiplatelet agent and its role in the management of acute coronary syndromes and following percutaneous coronary intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
