DENVER — Mild renal impairment constitutes an important new predictor of new-onset atrial fibrillation, Dr. Nicholas S. Peters reported at the annual meeting of the Heart Rhythm Society.
Dr. Peters of Imperial College London reported on 203 consecutive patients with new-onset atrial fibrillation (AF) and 781 without AF who were enrolled in the Imperial College New AF Study.
The mean serum creatinine level was significantly higher in patients presenting with their first episode of AF (94 micromol/L) than in controls (83 micromol/L). The AF patients had a mean estimated glomerular filtration rate (eGFR) of 68 mL/min per 1.73 m
An eGFR of less than 60 mL/min per 1.73 m
