Cardiovascular (CV) events are a major cause of mortality worldwide1 that are often precipitated by acute coronary syndromes (ACS). ACS result from the acute obstruction of coronary arteries and are defined as either unstable angina (UA) or myocardial infarction (MI), with or without ST-segment-elevation (STEMI and NSTEMI, respectively). Patients with moderate- to high-risk ACS are managed by an…

Acute coronary syndromes (ACS) have been associated with the occurrence of cardiovascular (CV) events. Moderate- to high-risk ACS are generally managed by an early invasive approach, where coronary angiography is followed by percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). However, ACS and the use of PCI or CABG are associated with a high risk of thrombotic…

Acute coronary syndromes (ACS) are a major reason for death and morbidity in the industrialised world. One of the most successful treatments for ACS has been strategies to target the platelets and inhibit their function.
Mechanisms of Platelet Activation
Thrombus formation in the arteries is dependent on platelets and their ability to attach to the injured wall despite the rapid arterial blood…

Acute coronary syndrome (ACS) is a term used to encompass unstable angina (UA) and myocardial infarction (MI) with or without electrocardiographic (ECG) evidence of ST-segment elevation. Antiplatelet therapy has formed the backbone of ACS management for decades and the drug class continues to evolve as novel agents with increasingly efficacious antiplatelet actions are identified. The main risk…

Clopidogrel is a key antiplatelet agent that inhibits the second step of platelet aggregation through blockade of the P2Y12-adenosine diphosphate (ADP) receptor.1 Its use has enabled percutaneous coronary intervention (PCI) to expand by dramatically reducing thrombotic complications in acute coronary syndromes (ACSs).2,3 Since the first report by Jaremo et al. of a large inter-individual…

The rare but catastrophic occurrence of stent thrombosis, in particular 'late' stent thrombosis, in association with deployment of drug-eluting stents has focused attention on the adequacy of the current dual anti-platelet regimen of aspirin and clopidogrel. Stent thrombosis is due to multiple factors. These include, specific stent features (delayed healing or polymer hypersensitivity),…

Ischaemic heart diseases (IHD) – mainly MI – represent a large disease burden all over the world. Almost 18 million people die each year from cardiovascular diseases, accounting for 31 % of deaths globally.1 Ticagrelor, the more potent cousin of antiplatelet therapy clopidogrel, has been shown to reduce the composite endpoint of death from vascular causes, MI or stroke by an additional 16 %…

Antiplatelet therapy is the standard of care for patients with acute coronary syndromes (ACS) and/or patients undergoing percutaneous coronary intervention (PCI) with stenting.1–3 Plaque rupture and/or iatrogenic vascular damage during PCI would normally result in the development of intravascular thrombus. Findings across multiple investigations consistently demonstrate the effectiveness of dual…
