Objective: Peripheral artery disease is a major clinical co-morbidity that can significantly affect quality of life, especially in the presence of diabetes mellitus and older age. The focus of this literature review is on medical management, through anti-platelet and anti-coagulation, of peripheral artery disease prior to undergoing surgical or endovascular management.
Method: Extensive electronic literature search performed in four major databases (PubMed, SCOPUD, Embase and Ovid) to identify the published randomized and non-randomized studies that compared and discussed the management of peripheral artery disease with different anti-thrombotic agents. Read More

A 45-year-old man presented with acute inferior myocardial infarction and underwent emergent coronary angiography (CAG). CAG revealed total occlusion of both the proximal right coronary artery (RCA) and distal left circumflex artery, and two bare-metal stents were deployed in the RCA. After the procedure, dual antiplatelet therapy (DAT) with 100 mg aspirin and 75 mg clopidogrel daily were given as usual, however, stent thrombosis occurred three times and he underwent repeat interventions.

Introduction: The transtelephonic electrocardiogram has been shown to have a great value in the management of out-of-hospital chest pain emergencies. In our previous study it not only improved the pre-hospital medical therapy and time to intervention, but also the in-hospital mortality in ST-segment elevation myocardial infarction. It was hypothesised that the higher in-hospital survival rate could be due to improved transtelephonic electrocardiogram-based pre-hospital management (electrocardiogram interpretation and teleconsultation) and consequently, better coronary perfusion of patients at the time of hospital admission.

Although used routinely to reduce thrombotic events in patients with coronary disease, the effects of P2Y inhibitors on thrombus stability and endogenous fibrinolysis are largely unknown. Blood taken from patients pre- and post-aspirin (n = 20) and on aspirin alone and on dual antiplatelet therapy comprising aspirin plus clopidogrel (n = 20), ticagrelor (n = 20) or cangrelor (n = 20), was tested using the Global Thrombosis Test.
