- Original description
This study investigates a portable thoracic bioimpedance tomography (TBIT) device designed to detect early lung congestion in heart failure patients. The main goal is to evaluate how well the device's measurements match those obtained from lung ultrasound and other imaging techniques. By detecting lung fluid build-up before symptoms worsen, this device could help manage heart failure more effectively outside of hospital settings, potentially improving patient care and reducing hospital admissions. Participants in the study are monitored using this device along with standard imaging methods, and data on heart failure symptoms are collected to understand the device\'s accuracy and usability.Read full original descriptionShow less

Inclusion: Adults aged 18 years or older; Diagnosed with heart failure, defined by the following criterion: hospitalization or an emergency visit for decompensated heart failure (pulmonary edema) within the last 12 months.
Exclusion: Pregnant women at the time of eligibility evaluation; Presence of an implanted electronic device in the thorax, such as a pacemaker or defibrillator; Inability to provide informed consent; Admission to intensive care or the coronary care unit.
