Patient-Related Factors Predicting Stent Thrombosis in Percutaneous Coronary Interventions.

ABSTRACT: Over the past four decades, percutaneous coronary intervention (PCI) safety and efficacy have significantly improved, particularly with the advent of the drug-eluting stent (DES). First-generation DESs reduced in-stent restenosis rates and targeted lesion revascularization; however, safety issues emerged, due to high incidences of stent thrombosis (ST) linked to death, myocardial infarction, and repeat revascularization. Second-generation DESs were developed to overcome these issues, reducing late-thrombotic-event risk while maintaining anti-restenosis efficacy. Nevertheless, ST still occurs with second-generation DES use. Stent thrombosis etiology is multifaceted, encompassing lesion-, patient-, procedural-, and stent-related factors. Overall, most early-stent-thrombosis cases are linked to procedural and patient-related aspects. Factors like premature discontinuation of dual antiplatelet therapy, resistance to clopidogrel, smoking, diabetes mellitus, malignancy, reduced ejection fraction or undertaking coronary angioplasty for an acute coronary syndrome can increase the risk of stent thrombosis. The aim of this study is to assess patient-related factors that potentially heighten the risk of stent thrombosis, with the objective of pinpointing and addressing modifiable contributors to this risk. By focusing on both patient- and procedure-related factors, a multifaceted approach to coronary revascularization can help minimize complications and maximize long-term benefits in managing ST.

Project description:BackgroundPatients treated with percutaneous coronary intervention are often considered to be at a high bleeding risk (HBR). Drug-eluting stents have been shown to be superior to bare-metal stents in patients with HBR, even when patients were given abbreviated periods of dual antiplatelet therapy (DAPT). Short DAPT has not been evaluated with the EluNIR ridaforolimus-eluting stent. The aim of this study was to evaluate the safety and efficacy of a shortened period of DAPT following implantation of the ridaforolimus-eluting stent in patients with HBR.Methods and resultsThis was a prospective, multicenter, binational, single-arm, open-label trial. Patients were defined as HBR according to the LEADERS-FREE (Prospective Randomized Comparison of the BioFreedom Biolimus A9 Drug-Coated Stent versus the Gazelle Bare-Metal Stent in Patients at High Bleeding Risk) trial criteria. After percutaneous coronary intervention, DAPT was given for 1 month to patients presenting with stable angina. In patients presenting with an acute coronary syndrome, DAPT was given for 1 to 3 months, at the investigator's discretion. The primary end point was a composite of cardiac death, myocardial infarction, or stent thrombosis up to 1 year (Academic Research Consortium definite and probable). Three hundred fifteen patients undergoing percutaneous coronary intervention were enrolled, and 56.4% presented with acute coronary syndrome; 33.7% were receiving oral anticoagulation. At 1 year, the primary end point occurred in 15 patients (4.9%), meeting the prespecified performance goal of 14.1% (P<0.0001). Stent thrombosis (Academic Research Consortium definite and probable) occurred in 2 patients (0.6%). Bleeding Academic Research Consortium type 3 and 5 bleeding occurred in 6 patients (1.9%).ConclusionsWe observed favorable results in patients with HBR who underwent percutaneous coronary intervention with a ridaforolimus-eluting stent and received shortened DAPT, including a low rate of ischemic events and low rate of stent thrombosis.RegistrationURL: https://www.clinicaltrials.gov; Unique identifier: NCT03877848.
