Adverse Effect of Bundle Branch Block on Exercise Performance in Patients with Fontan Physiology: from the Pediatric Heart Network Fontan Public Data Set
Journal of the American College of Cardiology(2023)
摘要
Patients with Fontan physiology have reduced exercise performance compared to their peers as well as a higher incidence of bundle branch block (BBB). This study aims to investigate the association between BBB and exercise performance in the Fontan population through a retrospective review of the Pediatric Heart Network Fontan study public use dataset. “Low Performers” were defined as ≤ 25th percentile (for Fontan patients) for each exercise parameter at anaerobic threshold (AT) for gender and age and “Normal Performers” were all other patients. A total of 303 patients with Fontan physiology who underwent exercise testing reached AT and had complete data for BBB. BBB occurred more frequently in Low Performers for VO2 [OR (95
