Caffeine consumption and incident atrial fibrillation in women.

ABSTRACT:

Background

It is somewhat controversial whether caffeine consumption is associated with an increased risk of developing atrial fibrillation (AF).

Objective

We prospectively assessed the relation between caffeine intake and incident AF.

Design

A total of 33,638 initially healthy women who participated in the Women's Health Study and who were gt 45 y of age and free of cardiovascular disease and AF at baseline were prospectively followed for incident AF from 1993 to 2 March 2009.
