FIGURE 1. Temporal Trends in the Rate of WHF Events.

FIGURE 1

Temporal trends in the rate of worsening heart failure (WHF) events by encounter type for heart failure with a (A) reduced, (B) midrange, (C) preserved, and (D) unknown ejection fraction (EF). The rate of WHF (per 100 person-years [PY]) was calculated by calendar year and stratified by encounter type and left ventricular EF. There has been a steady and consistent rise in the annual incidence of outpatient WHF that was consistently seen across all left ventricular EF categories. This underscores the growing importance of outpatient WHF events to appreciating the patient journey. HFmrEF = heart failure with a midrange ejection fraction; HFpEF = heart failure with a preserved ejection fraction; HFrEF = heart failure with a reduced ejection fraction.
