Read our Heart Failure research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers at the University of Calgary are testing two new ways to measure heart function that come from engineering principles. One method looks at how well your left ventricle (the heart's main pumping chamber) works, and the other measures how your blood vessels handle blood flow. The study will compare people with heart failure to people with healthy hearts to see if these new measurements can better understand how the heart is working.
Current methods for measuring heart function have important limitations. This research aims to develop better, non-invasive ways to assess heart performance that might help doctors understand and treat heart failure more effectively.

You would come to the University of Calgary for a single outpatient visit lasting a few hours. During this visit, researchers will perform non-invasive tests (like blood pressure monitoring and possibly heart imaging) to measure how your heart is working using the new assessment methods. You can either arrive on your own or be transported from a clinic with a research team member.
