A virtual cardiovascular rehabilitation program for secondary pan-vascular prevention in patients of diverse socioeconomic backgrounds with stroke, acute myocardial infarction, and other cardiovascular conditions.


Our research team has developed numerous technological innovations and advancements in the field of cardiovascular care including:

  • Developed a friendly and intuitive technology platform that empowers patients with cardiovascular diease to take a more active role in their care
  • Development of a loaner program for smart phones and smart watches to close the digital divide and promote health equity
  • Johns Hopkins installed smart TVs in the cardiology units to enhance patient and family education
  • Deployed an app to improve patient self-management in guideline-based care to heart attack patients hospitalized at 4 hospitals across 3 states in the MiCORE study
  • Development of “Stroke Goggles” to improve the diagnosis and care of stroke and recovery
