Association Between Peripheral Artery Disease and Incident Risk of Atrial Fibrillation: Strong Evidence Coming From Population-Based Cohort Studies.

Also, although ABI <1.0 alone was still found associated with the risk of AF, ABI >1.40 showed a nonsignificant trend in association. 6 Similar results were also reported by Griffin and colleagues, who performed an analogous analysis in the CHS (Cardiovascular Health Study) cohort, an observational population‐based study about risk factors for cardiovascular disease and their influence in disease progression in elderly (≥65 years) subjects. 7 To obtain more robust evidence about the relationship between PAD and AF, we merged together data coming from these 3 large population‐based studies: ARIC Study, MESA, and CHS.
