What is it about?
This work introduces PASS, a screening system that uses a simple light-based pulse sensor to detect a serious heart condition called aortic stenosis. Instead of relying on expensive imaging tests or specialized equipment, PASS analyzes tiny changes in the blood pulse measured from the fingertip. By studying these pulse patterns, the system can identify people who may have narrowing of the aortic valve, which restricts blood flow from the heart.

Why is it important?
Aortic stenosis is one of the most common heart valve diseases and can lead to heart failure if not detected early. Current diagnostic tools often require hospitals, trained staff, and high costs, making them less accessible for routine checks. PASS is unique because it is low-cost, easy to use, and suitable for large-scale screening in community or home settings. This could enable earlier diagnosis, timely referral to specialists, and better outcomes for patients at risk.
Perspectives
For me as a researcher, this project is meaningful because it shows how everyday signals, like the pulse from a fingertip, can reveal critical information about heart health. I believe technologies like PASS have the potential to bring specialized medical insights to wider populations, including communities with limited access to advanced healthcare. Our goal is not only to advance research but also to make heart disease screening more inclusive and practical.
