Are Serum Potassium and Magnesium Levels Associated with Atrial Fibrillation After Cardiac Surgery?

ABSTRACT:

Objectives

Potassium and magnesium are frequently administered after cardiac surgery to reduce the risk of atrial fibrillation (AF). The evidence for this practice is unclear. This study was designed to evaluate the relationship between serum potassium and magnesium levels and AF after cardiac surgery.

Design

Observational cohort study.

Setting

A cardiac intensive care unit in the United Kingdom.

Participants

Patients undergoing cardiac surgery between January 2013 and November 2017.

Interventions

None.

Measurements and main results

Cardiac rhythm was assessed using continuous electrocardiogram (ECG) monitoring in 3,068 patients on the cardiac intensive care unit. Associations between serum potassium and magnesium concentrations extracted from hos
