The association between social network index, atrial fibrillation, and mortality in the Framingham Heart Study.

ABSTRACT: Social isolation might be considered as a marker of poor health and higher mortality. The aim of our analysis was to assess the association of social network index (SNI) with incident AF and death. We selected participants aged ≥ 55 years without prevalent AF from the Framingham Heart Study.
