ABSTRACT In patients who have acute coronary syndromes and are treated with percutaneous coronary intervention, the prescription of a dual antiplatelet regimen, consisting of acetylsalicylic acid and a P2Y12 receptor inhibitor, is mandatory, contributing to the reduction of major cardiac events. However, while preventing ischemic events, this association may precipitate major bleeding complications, which is more commonly seen when more potent drugs, such as prasugrel or ticagrelor, are prescribed. These findings led to the search for therapeutic alternatives that could […]

ABSTRACT Currently, percutaneous coronary interventions account for more than 80% of myocardial revascularization procedures. This result was enabled by two major advances: the development of effective and safe drug-eluting stents, in addition to a potent and effective antithrombotic pharmacotherapy in the prevention of atherothrombotic events, which, in general, should be maintained for about 6 to 12 months after the index intervention. However, a significant number of cases (up to 20% of treated patients according to literature) are at risk for […]

ABSTRACT Since the mid-1990s, the dual antiplatelet therapy, consisting of the association between acetylsalicylic acid and a platelet P2Y12 receptor inhibitor, is the core of thrombosis prevention after coronary stent implantation, regardless of the models used. It is also used to prevent the occurrence of atherothrombotic events in the late phase after the intervention. The clinical presentation of coronary artery disease influences the duration of dual therapy, which tends to be longer in treated cases of acute coronary syndrome (usually […]

ABSTRACT Acute coronary syndromes are common situations in medical practice, with high morbidity and mortality. Consequent to its relevance, its clinical management has always been subject of discussion and controversy. Since the past decade, the dual antiplatelet regimen has been the main therapeutic option used in its passivation, whereas percutaneous interventions have become the most common therapeutic option. Clopidogrel, the drug initially used in combination with aspirin, is effective and safe; however, it has disadvantages that led to the development […]
