Vest to detect acute decompensated heart failure
A vest designed to monitor heart failure patients in their home and detect when their condition is worsening is under development in the US.
The early detection of acute decompensated heart failure (ADHF) could lead to changes to treatment and other interventions that prevent hospitalisation.
Yeonsik Noh, an assistant professor who holds a joint appointment at the University of Massachusetts Amherst’s Elaine Marieb College of Nursing and the College of Engineering’s electrical and computer engineering department, has been awarded a four-year, $2.3m grant from the US National Institutes of Health’s National Heart, Blood and Lung Institute to advance, refine and test the technology.
Noh said that early detection of decompensated heart failure usually relies on monitoring weight gain, but this metric alone does not accurately gauge the fluid accumulation that predicts the decline of patients with heart failure.
According to Noh, a device that measures vital signs including heart rates and respiratory rates, intrathoracic fluid status using thoracic bioimpedance, and heart rhythm could allow for more accurate identification of the early stages of acute decompensation in chronic heart failure patients.
