New Delhi, July 30 -- could adhesive sensor stickers and a neural network do what a hemodynamic analyzer at a specialized cardiac clinic does?

The answer, according to research published in April 2026 in MDPI Bioengineering, is yes, with reservations the researchers themselves are careful not to minimize.

The team was led by Patricia Angela R. Abu of Ateneo de Manila University's Department of Information Systems and Computer Science, with thirteen collaborators from institutions in the Philippines, Taiwan, and mainland China. Together, they built a feedforward artificial neural network to predict a patient's cardiac index, a measure of how efficiently the heart pumps blood relative to body surface area. Clinicians use the cardiac index...
