Impact of Spiroergometer Parameters as Diagnostic Marker of Cardiac Ischemia in Pts. With Stable Angina Compared to FFR.
Impact of Ergospirometric Oxygen Uptake Under Exercise as Diagnostic Marker of Cardiac Ischemia in Patients With Stable Angina Compared to Non Invasive and Invasive (FFR) Measurement of Ischemia
Source: ClinicalTrials.gov · Last updated 6 Aug 2026
Brief summary (registry, in English)
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 spiroergometer might help to improve diagnostic accuracy of non invasive exercise testing. Therefore the trial is evaluating diagnostic accuracy of spiroergometric parameters compared to invasive FFR measurement.
