Summary

This study looks at whether a cardiopulmonary exercise test (CPET) can help predict serious heart problems in people with coronary heart disease. Researchers will review medical records from 15,000 patients and track their health over time. The goal is to see if CPET results are linked to future heart attacks or death.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help doctors better predict heart complications in coronary heart disease patients using a simple exercise test.
What could go wrong
This is an observational study, not a treatment trial. It may not prove cause and effect, and results might not apply to all patients.
