USE CASE
Develop the Safe Heart application that records information about a patient’s health
and estimates the 10-year cardiovascular risk of an individual
ACTORS Clinician, Patient
PURPOSE To calculate and keep track of Reynold’s risk score for a patient
DESCRIPTION The Safe Heart application will present registered patients vitals and lab
measurements (imaging results and device measurements) and the calculated
Reynolds Risk Score, which predicts the risk of having a future heart attack, stroke,
or other major heart disease in the next 10 years, along with a succinct, patient-
friendly explanation for each result. Furthermore, the Safe Heart app also offers
simulation: the clinician or patient can make changes to one or more of the patient’s
vitals or lab results to see how the patient’s current Reynolds Risk Score could be
improved. Clinicians can search for patients of certain characteristics, and view
different statistics about their Reynolds Risk Score. This helps them get an
understanding of the health demographic in their neighbourhood.

CROSS-REFERENCE None
TYPICAL COURSE OF EVENTS:
Actor Action
System Response
The patient enters values and details. The application calculates the Reynold risk score
for any heart disease for the next 10 years.
The Reynolds risk score is generated for the view
of the patient and the clinician.
The clinician can search any patient’s Reynolds risk
score and provide solutions.
The patient enters new values for the vitals and lab
measurements.
Reynolds risk score is re-calculated by the
application.
The new Reynolds risk score is generated from the
newly calculated values by the application and then
a report is generated which has an explanation of
new results based on the change in the vital and lab
measurements.
The patient now can compare the old and new
reports for further clarification and check for
improvements with different results.
