Key result
Atrial fibrillation was associated with a significantly higher risk of cardiovascular death or heart failure readmission in patients with acute decompensated heart failure and mild to moderate mitral regurgitation (HR 1.381).
Why the study?
AF and MR are frequently combined in patients with HF, but the effect of AF on the prognosis of patients with HF and MR remains unknown.
Cohort (n=867)

Effect of AF on prognosis in HF with MR remains unknown; leaves open need for dedicated studies.
Background:Atrial fibrillation (AF) and mitral regurgitation (MR) are frequently combined in patients with heart failure (HF). However, the effect of AF on the prognosis of patients with HF and MR remains unknown.

Hirai et al. (2021) conducted a cohort in Acute decompensated heart failure (n=867). Atrial fibrillation vs. No atrial fibrillation was evaluated on Composite of cardiovascular death and heart failure-related readmission (HR 1.381, 95% CI 1.022-1.866, p=0.036). Atrial fibrillation was associated with a significantly higher risk of cardiovascular death or heart failure readmission in patients with acute decompensated heart failure and mild to moderate mitral regurgitation (HR 1.381).
