This study is testing a drug called *omecamtiv mecarbil* to see if it helps people with serious *heart failure*. Heart failure is when the heart doesn't pump blood as well as it should. The study focuses on people with a severely reduced *ejection fraction*, which is a measure of how much blood the heart pumps out with each beat. Participants will be split into two groups: one group will get the drug, and the other will get a placebo (a pill that does nothing). The study lasts up to 3 years and aims to find out if the drug can reduce the risk of events like heart failure hospitalizations or heart-related deaths.
- Participation may last up to 3 years.
- Participants need to be between 18 and 85 years old.
- Must have a history of chronic heart failure and be on certain medications.
If you have severe heart failure and meet the study's criteria, this study could offer a chance to try a new treatment. However, always consider potential risks and discuss participation with your doctor.
