Figure 3. Subgroup analysis of the effect of baseline characteristics on new‐onset atrial fibrillation in the moderate and high premature ventricular complex groups (PVC daily count ≥1000/day).

Younger patients (<60 years old) in the moderate and high PVC burden groups were at a higher risk of new‐onset AF, whereas sex, history of diabetes, heart failure, and coronary artery disease did not have an impact on new‐onset AF. AF indicates atrial fibrillation; CAD, coronary artery disease; HF, heart failure; HR, hazard ratio; and PVC, premature ventricular complex.
