Individuals with obesity and a history of heart or kidney-related disease will be eligible for participation. Study participants will have a 50:50 chance to be randomly assigned to either the treatment (retatrutide) or control (placebo) group. Retatrutide is currently considered an investigational medication as it has not been approved by the FDA for the treatment of obesity or any other medical condition at this time. Study participation will last approximately 5 years and begin with a screening period to ensure correct patient selection. Research clinic visits will occur every 4 weeks initially and then every 12 weeks. Some visits may be completed virtually through telehealth or by phone. Study procedures include but are not limited to: blood draws, questionnaires, self injection of study medication, medical history review, vital signs, and electrocardiogram. The medication will be injected subcutaneously once a week. The medication's purpose is to facilitate weight loss and decrease a subject's risk for heart or kidney related disease progression or events.

The study will aim to link data collected during the DELIVER Randomized Contolled Trial (RCT) to Real World Data (RWD) during the 10 year period following subject participation in the clinical trial. Only individuals who participated in the DELIVER clinical trial will be approached to participate in this research. The study team will need to collect some of the subject's personal health identifiers. A research team at Brigham and Women's Hospital, the coordinating center for the DELIVER Trial, will then use the subject's personal identifiers to obtain data from subjects' health insurance and/or hospital systems.

The purpose of this study is to evaluate the potential effectiveness, outcomes, and safety (before, during, and after study procedures) of the Inter Atrial Shunt Device (IASD) in the treatment of subjects with heart failure symptoms and relatively normal pumping of the heart. This study involves the use of an investigational medical device called the Corvia Atrial Shunt (CAS) System. The CAS is permanently implanted in the heart to reduce the increased pressure in the left side of the heart by creating a small opening between the two upper chambers of the heart. Participants will have a 50% chance of being in either group A having the CAS placed or group B and not receiving the device. Subjects will have 7 research clinic visits, and multiple telephone calls for a total of 5 years of follow-up. The research clinic visits will include medical exams, health questionnaires, ECG and echocardiogram of the heart and 6 minute hall walk tests.
