iHeart

iHeart, built by Canadian company VitalSines International, is a fingertip clip and app that derives aortic pulse-wave velocity from the pulse wave and reports it as an "internal age." Co-founder Dr. Jess Goodman presented the science behind it at TechTO's HealthTO in January 2017.

About

iHeart is a consumer device from VitalSines International that clips to a fingertip and estimates aortic stiffness, a measure that research has linked to risk of death from all causes, presenting it to users as an "internal age." Physician co-founder Dr. Jess Goodman built it after promising his Tai Chi teacher, a Taoist monk he had studied under for twenty years, that he would show people why the stretch between the heart and the kidneys mattered. Goodman has been explicit that it is a health-and-wellness tool rather than a medical device, and that aortic stiffness responds to exercise, diet and stress reduction. The company has since added a remote patient monitoring offering. It is unrelated to iHeartRadio.

Quick answers

What does iHeart measure?

Aortic pulse-wave velocity, taken from the fingertip pulse wave. Stiffness of the aorta has been studied as a predictor of risk of death from all causes, and iHeart reports it to users as an internal age.

Is iHeart related to iHeartRadio?

No. iHeart is a health device from VitalSines International and has no connection to iHeartRadio or iHeartMedia.
