•Age \>18 years of age
•Diagnosis of HF and LVEF \<40% on most recent imaging assessment within 1 year prior to screening. Any validated method for assessing LVEF may be used for enrollment including echocardiogram, cardiac magnetic resonance imaging, etc. For participants with an LVEF reported qualitatively (e.g., moderate LV dysfunction) or as a range on the most recent imaging assessment that includes 40% (e.g., 35-45%), then the site investigator should review the imaging study and determine if the participant has an LVEF \<40%. Participants with a new diagnosis of HFrEF may be enrolled. The enrollment will be monitored to ensure no more than 50% of the total cohort have new-onset HFrEF.
