Lower soluble Klotho and higher fibroblast growth factor 23 serum levels are associated with episodes of atrial fibrillation

There is a gradient between the LA and peripheral vein in the markers of calcium-phosphate metabolism in patients undergoing PVI. Lower sKlotho and higher iFGF23 serum levels are associated with episodes of AF. Serum iFGF23 gradient is a potent predictor for the recurrence of AF.
