Why the study?

Metformin demonstrates broad cardiovascular benefits beyond glucose lowering, but its roles in cardiac arrhythmias remain unclear.

Overview

Metformin-associated AF reduction in diabetes is hypothesis-generating; prospective RCTs needed before clinical consideration.

Structured PICO

P
Population
In vitro, in vivo, and clinical studies evaluating the effects of metformin on cardiac arrhythmias
I
Intervention
Metformin

This review highlights the potential of metformin to reduce atrial fibrillation incidence through AMPK-mediated structural and electrical remodeling, while noting a lack of clinical benefit for ventricular arrhythmias.

Limitations

  • limited numbers of reports
