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 drugeluting 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 developing significant bleeding, which can have a serious impact on prognosis. Therefore, this population requires a series of care measures related to indication, performance of the procedure, and late followup. The process begins with the identification of the most predisposed cases, which, in most situations, is simple, and there are risk scores that help the cardiologist. Next, the indication of the procedure should be done appropriately. Care begins with the preferential prescription of clopidogrel instead of other P2Y12 inhibitors; at the time of the procedure, whenever feasible, the option for the radial access is advantageous, especially in acute coronary syndromes. The use of a drugeluting stent is also recommended in these cases, since contemporary stents are safe enough to safely shorten the duration of use of the dual antiplatelet regimen. Finally, more recently, monotherapy with P2Y12 receptor inhibitors has been discussed, in which early withdrawal of acetylsalicylic acid would not compromise safety and, at the same time, it would be able to prevent major bleeding events. |
