Randomized Controlled Trial
Very long-term outlook of acute coronary syndromes after percutaneous coronary intervention with implantation of polymer-free versus durable-polymer new-generation drug-eluting stents.
Detailed long-term follow-up data on patients with acute coronary syndromes (ACS) in general, and those with ST-elevation myocardial infarction (STEMI) in particular, are limited. We aimed to appraise the long-term outlook of patients undergoing percutaneous coronary intervention (PCI) with state-of-the-art coronary stents for STEMI, other types of ACS and stable coronary artery disease (CAD), and also explore the potential beneficial impact of new-generation polymer-free drug-eluting stents (DES) in this setting. ⋯ Unstable coronary artery disease, especially when presenting without ST-elevation, represents an informative marker of adverse long-term prognosis in current state-of-the-art invasive cardiology practice. Even considering admission diagnosis, and despite of using no polymer, polymer-free DES showed similar results with regards to safety and efficacy when compared with DES with permanent polymer.
