Is There an Association between Epicardial Adipose Tissue and Outcomes after Paroxysmal Atrial Fibrillation Catheter Ablation?

Background: In patients undergoing paroxysmal atrial fibrillation (PAF) ablation, pulmonary vein isolation (PVI) alone fails in maintaining sinus rhythm in up to one third of patients after a first catheter ablation. Epicardial adipose tissue (EAT), as an endocrine-active organ, could play a role in the recurrence of AF after catheter ablation.

Objective: To evaluate the predictive value of clinical, echocardiographic, biological parameters and epicardial fat density measured by computed tomography scan (CT-scan) on AF recurrence in PAF patients who underwent a first pulmonary vein isolation procedure using radiofrequency (RF).

Temporal trends in mortality and readmission after acute heart failure: a systematic review and meta-regression in the past four decades.

Aims: Acute heart failure (AHF) is frequent and life-threatening disease. However, innovative AHF therapies have remained limited, and care is based on experts' opinion. Temporal trends and benefits of long-term oral cardiovascular medications on AHF outcomes remain uncertain.
