The main purpose of this study is to assess how well LY3971297 is tolerated and what side effects may occur in participants with heart failure with preserved ejection fraction (HFpEF) and participants with heart failure with reduced ejection fraction (HFrEF). Blood tests will be performed to investigate how the body processes the study drug and how the study drug affects the body. For each participant, the study will last about 2 months and will include 1 inpatient visit lasting approximately 4 days and 5 outpatient visits.A teljes eredeti leírásKevesebb
