Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients referred for a myocardial perfusion PET/CT scan at Kuopio University Hospital.
✕Probably not a fit
Patients under 18 years, pregnant or breastfeeding, or those with certain disabilities or legal restrictions may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study aims to evaluate the effectiveness of cardiopulmonary exercise testing (CPET) in diagnosing myocardial ischemia by comparing its results with those from myocardial perfusion PET/CT scans. Patients referred for a PET/CT scan at Kuopio University Hospital will undergo CPET on a separate day. The study will assess whether the gas exchange parameters from CPET correlate with any perfusion defects identified in the PET/CT scan. Additionally, patients who receive invasive coronary treatments will participate in follow-up tests to evaluate recovery of myocardial perfusion through CPET six months post-treatment.
Why it matters
Potential benefit: If successful, this study could improve the diagnostic accuracy for myocardial ischemia, leading to better patient outcomes.
How similar studies have gone: While the approach of using CPET in this context is innovative, similar studies have shown promise in correlating exercise testing with cardiac conditions.
