Advancing Mobile Technologies to Reduce Disparities in Cardiovascular Health

Project: SFRN


  • Seth Shay Martin (PI)


With our collaborative project spanning the patient experience from diagnosis to management, we will improve patient care throughout the patient journey. During Years 1 and 2, our Center team will focus on technology advancement and symbiotic learning between our diagnosis and management cores, with multiple opportunities for intra- and inter-institutional collaboration. During Years 3 and 4, our team will focus on testing the value of each of our technologies in patients with stroke and heart diseases in real world clinical settings. Throughout our work, we will bring an equity-first lens consistent with the AHA's Health Techquity Initiative.Aim 1 (Diagnosis Focused). To test the hypothesis that a novel smartphone software application can be used to accurately and reliably quantify the H.I.N.T.S. exam to aid correct diagnosis of posterior fossa (brainstem or cerebellar) stroke vs. vestibular neuritis (labyrinthitis) in acute dizziness/vertigo in diverse populations.Subaim 1.1: To optimize smartphone head tracking and eye tracking algorithms for high precision measurements during H.I.N.T.S. (Head-Impulse test of vestibulo-ocular reflex function, Nystagmus type, and Test of Skew deviation).Subaim 1.2: To test the usability, reliability, and accuracy of the smartphone app approach under typical clinical conditions in the Emergency Department.Subaim 1.3: To assess the usability, reliability, and accuracy of self-administered smartphone-based testing in a demographically-diverse population.Aim 2 (Management Focused). To develop and test a virtual cardiovascular rehabilitation program ("Corrie CV Rehab") for secondary pan-vascular prevention in patients of diverse socioeconomic backgrounds with stroke, acute myocardial infarction, and other cardiovascular conditions, and develop an innovative technology to guide patients in safe driving after stroke.Subaim 2.1: To develop Corrie CV Rehab through participatory product design, directly involving demographically-diverse patients, caregivers, and other stakeholders in design and beta testing.Subaim 2.2: To assess the impact of Corrie CV Rehab on AHA's Life Simple 7, as compared to standard of care alone. Subaim 2.3: To develop a set of at-home screening tests that educate and triage patients who have the potential and intention to drive after stroke.
