Brief Summary
Researchers are looking for a better way to treat people who have chronic heart failure with reduced ejection fraction. Chronic heart failure with reduced ejection fraction (HFrEF) is a long-term condition that occurs when the heart is too weak to pump enough blood to the rest of the body. This results in a reduced supply of the oxygen that the body requires to function properly. The common symptoms of HFrEF include breathlessness, weakness, fatigue, and swelling in the ankles and legs. If left untreated, heart failure can lead to other serious health problems, including damage to other organs, which may result in hospital stays or even death. Vericiguat is an approved drug for use in people with chronic HFrEF. It works by activating a protein called soluble guanylate cyclase, which helps dilating the blood vessels and in turn improves heart function. Currently, treatment with vericiguat starts at a daily dose of 2.5 milligrams (mg), which increases to 5 mg after 2 weeks. The dose is then increased to the target dose of 10 mg after another 2 weeks. In this study, researchers are trying to learn how well participants can tolerate and how safe it is to start vericiguat at a dose of 5 mg. Starting directly at the 5 mg dose is expected to help reach the target dose of 10 mg faster. Participants will take vericiguat 5 mg as a tablet by mouth once daily along with their regular heart medications. At the start of the study, study doctors will check participants' medical history and perform full health check-ups to confirm if they can take part in the study. Throughout the study, study doctors will monitor participants' previous and current medications, their heart health, and their overall well-being. This will help researchers assess how safe the study drug is and if they experience adverse events. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective of whether they think they are related to the study treatment. Access to study treatment after the end of this study is not planned. Everyone, including study doctors and participants, will know what drug the participants receive during the study. Participants may be in the study for about 4 weeks. Participants may not benefit from the treatment as the study is designed to assess safety and tolerability: the duration of the study is very short and participants will be taking a low dose of vericiguat without moving to the target dose of 10 mg during the study. However, the findings of this study may enable people with chronic HFrEF to safely skip one initial dosing step and reach the target dose of vericiguat faster. Participants may experience medical problems such as low blood pressure, upset stomach, nausea, dizziness, and headache. Researchers will monitor and manage all these, and other, medical problems participants may have during the study.

Limitations and Caveats
Study Design: This analysis is based on a single-arm design, which may limit the generalizability of the findings. The absence of a control group restricts our ability to make definitive conclusions about the tolerability and safety of starting vericiguat at 5 mg/day to standard care or placebo. The results are based on descriptive statistics, which provide a summary of the data but do not infer causality or generalizability to a broader population.
