Description as written by the study sponsor.

The goal of this clinical trial is to learn if tirzepatide works to improve physical function in adults with heart failure and obesity. It will also learn about the safety of tirzepatide. The main questions it aims to answer are: Does tirzepatide improve how far participants can walk in 6 minutes? Does tirzepatide improve heart failure symptoms and quality of life? What side effects do participants have when taking tirzepatide? Researchers will compare tirzepatide to a placebo (a look-alike substance that contains no drug) to see if tirzepatide improves physical function in people with heart failure and obesity. Participants will: Get a weekly injection of tirzepatide or a placebo under the skin for 6 months Start at a low dose, which may be raised slowly based on how well they tolerate it Keep taking their usual heart failure medicines Visit the clinic for checkups, blood tests, heart ultrasounds, and a 6-minute walk test Answer questions about their quality of life and heart failure symptoms
