Summary

This trial tests if a computer-controlled gas challenge is safe & effective for detecting heart disease in healthy people.

Who is the study for?
This clinical trial is open to adults aged 45 and older who have no known heart disease. Participants must be able to increase their breathing rate when asked, not be pregnant or nursing, don't have an IUD, can lie on their back for up to 40 minutes, and don't suffer from serious neurological, lung, kidney or liver diseases.
What is being tested?
The study is testing the safety and effectiveness of a needle-free method called RespirAct. It involves controlled breathing challenges using computer precision to detect coronary artery disease in healthy individuals.
What are the potential side effects?
Since this trial involves non-invasive respiratory tests with RespirAct in healthy subjects without known cardiac issues, significant side effects are not anticipated. However, discomfort due to increased breathing rates may occur.
