The recent demonstration that high on-treatment platelet reactivity is a common phenomenon, and that these patients have a worse prognosis when undergoing coronary angioplasty, along with the development of new devices for assessing platelet aggregation, reliably and relatively simple, led to an exponential increase in the scientific interest on the subject. Considering just the PubMed database, there were only 358 publications in the 70', whereas in the past decade that number went up to 8,218. However, as often happens with emerging subjects, despite the large amount of knowledge produced, there is now a lot more questions than answers. The aim of this project is to contribute to a better understanding of the subject, seeking answers to a number of pathophysiological questions that today permeate the literature. Some questions that we intend to answer are: Is there any difference in platelet aggregability between patients with initial coronary artery disease diagnosed by multislice computed tomography and those with normal coronary arteries?; Does renal function have any influence on the antiplatelet potency of clopidogrel or ticagrelor?; Does glucose-lowering DPP4-inhibitors influence platelet aggregation in patients with acute coronary syndromes?; Can the evaluation of platelet aggregation lead to better use of hemostatic techniques in dental extractions?; What results would be obtained when comparing prasugrel and ticagrelor in the same population, and what is the correlation between them and adenosine plasma concentration?; Exercise training influences platelet aggregability and sympathetic activity in patients with acute myocardial infarction?
