This study of 801 multiple myeloma patients found that atrial fibrillation occurred in 5.5% within 90 days after autologous stem cell transplantation—nearly double previously reported rates—indicating disease‑specific risks. AF strongly predicted mortality from non‑relapse causes and may serve as a marker of physiological vulnerability, emphasizing the value of expanded pre‑transplant cardiac assessment and monitoring.
