The "obesity paradox" in patients with atrial fibrillation: Insights from the Gulf SAFE registry.

Background: The prognostic impact of obesity on patients with atrial fibrillation (AF) remains under-evaluated and controversial.

Methods: Patients with AF from the Gulf Survey of Atrial Fibrillation Events (Gulf SAFE) registry were included, who were recruited from six countries in the Middle East Gulf region and followed for 12 months. A multivariable model was established to investigate the association of obesity with clinical outcomes, including stroke or systemic embolism (SE), bleeding, admission for heart failure (HF) or AF, all-cause mortality, and a composite outcome.

Symptom Status, Clinical Subtypes, and Prognosis in Patients With Atrial Fibrillation from the Middle East Region (from the Gulf-SAFE Registry).

Atrial fibrillation (AF) is often asymptomatic. The prognosis of asymptomatic AF is at least similar or worse than symptomatic AF, but there are no such data from Middle East patients with AF. The Gulf-SAFE (Gulf Survey of Atrial Fibrillation Events) registry is a multicenter prospective survey of patients presenting with AF to participate medical institutions in 6 countries in the Gulf region.
