Leistner DM, et al. – In this study, researchers determined the prevalence and impact of infections in 644 patients ≥ 80 years of age undergoing percutaneous coronary intervention (PCI). Based on the presence/absence of infections requiring antibiotic therapy, participants were stratified. During 1.2 years of median follow-up, major adverse cardiovascular events (MACE) post-discharge were assessed. Older patients, more often women, and those with an increased prevalence of atrial fibrillation and congestive heart failure tended to have infections. In this elderly patient population undergoing PCI, a frequent prevalence of concomitant infections was reported. An increased risk of adverse events was observed in relation to concomitant infections when affecting the respiratory system.
