Blood sugar sensitivity may determine heart procedure success

This study checks if insulin resistance (when your body doesn't use insulin well) can predict whether a heart procedure called pulsed field ablation will work for people with atrial fibrillation (an irregular heartbeat). About 120 non-diabetic patients having their first ablation will give a blood sample before the procedure. Researchers will measure insulin resistance and follow up 4-5 months later to see who needs a repeat procedure. The goal is to find out if treating insulin resistance could improve ablation success.
