Outcomes
The primary outcome was acute HF event rate within 30 days. HF was
defined as any clinical encounter that invoked a HF exacerbation,
including any telephone encounter, office visit, emergency room visit,
hospitalization, or positive response to the 30-day follow-up survey
(see supplemental figure 1). For the purposes of this study, diuretic
medication adjustment was required to meet the primary endpoint. The
secondary outcome was rate of AF-free HF events within 30 days.
