A rapid noninvasive wearable device for assessing cardiac troponin I level.

ABSTRACT:

Objective

Chest pain, a common emergency department presentation, requires rapid evaluation. The current gold standard of care is serial troponin measurements from blood draws along with an electrocardiogram and clinical presentation. However, an optical technology-based noninvasive wearable device, the Infrasensor, which can rapidly and transcutaneously assesses cardiac troponin I (cTnI), was recently developed. We aimed to perform a pilot study to evaluate the performance of the Infrasensor in cTnI defined cohorts.

Methods

This was a 10-hospital prospective observational study in healthy US subjects with a normal cTnI level and in patients with an elevated local cTnI level. Healthy subjects as determined by a negative questionnaire and bloodwork underwent 3-minute Infrasen
