Summary

This study tests whether using lung ultrasound to guide fluid removal in adults hospitalized for acute heart failure leads to better outcomes than standard physical exams. Researchers will compare how long patients stay alive and out of the hospital over 40 days, as well as symptoms and quality of life. About 222 participants will be enrolled.
