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.
