We evaluated the clinical and stent-related risk factors for recurrent angina (RA) symptoms after percutaneous coronary intervention (PCI), as identifying and treating them could improve patient outcomes. We retrospectively analysed patients readmitted at our clinic after successful PCI; 147 (81.66%) patients were hospitalised for RA. Advanced age was associated with RA symptoms. Drug-eluting stents used at the index PCI, especially in small coronary arteries, seemed protective against RA symptoms. In-stent restenosis, which was associated with RA, was more frequent in bare-metal stents than in drug-eluting stents. Further studies are needed to identify other potential risk factors for RA and to determine how to positively influence the evolution of known risk factors.
