Leistner DM, et al. - Researchers determined how outcomes of percutaneous coronary intervention were influenced by the presence of infections in 644 patients ≥80 years of age. These patients underwent stratification based on the presence/absence of infections requiring antibiotic therapy and were followed-up for a median duration of 1.2 (interquartile range 0.1 to 3.4) years. During index hospitalization, infections were present in 186 (28.9%), with 84 (13%) cases of pneumonia and 59 (9.2%) cases of urinary tract infections. Patients with infections were older, more often women, and had an increased prevalence of atrial fibrillation and congestive heart failure. A frequent prevalence of concomitant infections was observed in this study population. An increased risk of adverse events was reported in relation to the presence of concomitant infections affecting the respiratory system.
