Key result
Faster atrial mechanical recovery links to hypertension, lone AF, AF <24 hours, and normal LA size.
Why the study?
The timing and extent of restoration of atrial mechanical function after conversion from atrial fibrillation to sinus rhythm in patients with different etiologies were unclear.
Does the etiology, duration of atrial fibrillation, and left atrial size affect the timing of restoration of atrial mechanical function after conversion to sinus rhythm?
Observational (n=60)
Does the etiology, duration of atrial fibrillation, and left atrial size affect the timing of restoration of atrial mechanical function after conversion to sinus rhythm?
The recovery of atrial mechanical function after conversion to sinus rhythm is delayed in patients with ischemic cardiopathy, longer duration of atrial fibrillation, and enlarged left atria, highlighting the need for follow-up assessment of atrial contraction.
No takes yet. Share an insight, caveat, or question.
May inform post-cardioversion monitoring in select AF patients; leaves open whether these factors warrant tailored anticoagulation strategies.
Mattioli et al. (2008) conducted an observational in Atrial fibrillation (n=60). Etiology, duration of atrial fibrillation, and left atrial size vs. Ischemic cardiopathy, AF duration >24h, and enlarged left atrium was evaluated on Restoration of atrial mechanical function (peak A velocity and A wave integral). Restoration of atrial mechanical function occurred earlier in hypertensive patients, those with lone atrial fibrillation, AF duration <24 hours, and normal left atrial size.
