Impact of Spiroergometry Parameters as Diagnostic Marker of Cardiac Ischemia in Pts. With Stable Angina Compared to FFR.


In Patients with stable Angina pectoris CCS 1-3 exercise testing for ischemia detection is widely used despite the known limitations. Measurement of the FFR is invasive but gold standard for Ischemia detection.

Adding of parameters of spiroergmetry might help to improve diagnostic accuracy of non invasive exersice testing. Therefore the trial is evaluating diagnostic accuracy of spiroergometric parameters compared to invasive FFR measurement.
