Background Interatrial block (IAB) is associated with atrial fibrillation (AF) in different clinical situations, but little information exists in elderly patients with myocardial infarction (MI) and its association with frailty. Methods Consecutive MI patients aged ≥ 75 years were prospectively included. Frailty was assessed during the admission, as well as the prevalence of IAB. Main outcome measure was mortality and new onset AF at one year. Results We included 254 patients. From 220 patients with sinus rythm (86.6%), 37 had partial IAB (16.8%) and 34 advanced IAB (15.5%). Patients with advanced IAB had lower values of handgrip strenght (19.8 vs 21.7 kg, p 0.073). These patients had a trend toward higher incidence of AF or mortality during follow up (HR 1.51, 95% CI 0.85–2.70, p = 0.164). Conclusions Advanced IAB was associated with a trend toward higher prevalence of frailty. Elderly patients with MI and advanced IAB had a trend toward higher incidence of AF.
