After an episode of acute ischemic syndrome, patients with concomitant peripheral arterial disease have a worse short- and long-term prognosis compared to patients with isolated coronary disease, but the mechanisms responsible are poorly understood. In this population, the presence of high platelet aggregability despite the use of antiplatelet drugs is related to a greater risk of future complications, including heart attack and death from all causes. Thus, the main objective of the present project is to evaluate the role of platelet aggregability, analyzed by optical aggregometry using the AggRAM® equipment, in patients with a history of previous acute myocardial infarction with and without the presence of peripheral arterial disease. Among the secondary objectives, it is worth analyzing platelet aggregability, in both groups, using the Plateletworks® method. This is a case-control study, with groups differentiated by the presence or absence of peripheral arterial disease, matched by sex and age. It is expected that, in the end, relevant aspects related to platelet aggregation will be better characterized in this high cardiovascular risk population, with a likely impact on new therapeutic strategies that can positively influence the morbidity and mortality of these patients.
