iHeart predicts physiological age via cardio test
A team from Toronto has created a modified pulse oximeter that can purportedly predict your physiological age by reading how your heart beats pulse through your finger. The iHeart physiological age system is based on an algorithm to determine the aortic pulse wave velocity (PWV). The pulse wave velocity is a measurement of the time it takes a pulse of blood to travel through a blood vessel, and is strongly correlated with arterial stiffness and plaque buildup.
The stiffer the artery, the faster the pulse travels, and the shorter the PWV. Multiple studies have found that this measurement is a strong independent predictor of cardiovascular morbidities and mortalities.
Most systems to measure PWV are relatively complex, using multiple leads placed on the body. The iHeart system, developed by Dr. Jess Goodman, works on a proprietary method to determine the aortic pulse wave velocity by looking for the reflected wave from the aortic bifurcation. As this reflected wave is only a tiny blip in a pulse reading, the iHeart system comes with a custom-designed pulse oximeter capable of detecting minute transient fluctuations in the pulse.
iHeart’s goal is to make people more cognizant of your cardiovascular health. With an easy way of measuring the PWV, iHeart wants you to track your health as you progress through a workout routine or diet to monitor how you’re doing.
iHeart is running a crowdfunding campaign to fund its start-up. The system is available now on Indiegogo for $99, with shipping expected in February 2015.
