Association Between Pulmonary Vascular Volume and Cardiac Structure and Function in Patients With Atrial Fibrillation
Why the study?
Little is known about pulmonary vascular changes in patients with cardiac disease.
Is reduced pulmonary vascular volume associated with impaired cardiac structure/function and persistent atrial fibrillation in patients undergoing AF ablation?
Population
742 patients who underwent ablation for AF
Comparison
Pulmonary vascular volume compared with echocardiographic measures and AF severity
Design
Retrospective observational study

Implication
May highlight cardiopulmonary interactions in AF; leaves open whether small-vessel PVV aids pre-ablation risk stratification.
Structured PICO
Is reduced pulmonary vascular volume associated with impaired cardiac structure/function and persistent atrial fibrillation in patients undergoing AF ablation?
P
Population
742 patients with atrial fibrillation (median age 63 years, 70% men) who underwent ablation at a single center in Denmark.
O
Outcome
Association of pulmonary vascular volume (PVV) with echocardiographic measures of cardiac structure and function, and with AF severity (persistent vs. paroxysmal AF).surrogate
Reduced small-vessel pulmonary vascular volume on CT is independently associated with persistent atrial fibrillation and impaired cardiac structure and function, highlighting important heart-lung interactions in AF.
