Using Cardiopulmonary Exercise Testing to Diagnose Myocardial Ischemia Comparison With Myocardial Perfusion PETCT Scan Results

What this Trial Is About

Researchers are investigating whether cardiopulmonary exercise testing CPET can help diagnose myocardial ischemia by comparing it with myocardial perfusion PETCT scan results. The study recruits patients referred for PETCT scans at Kuopio University Hospital to evaluate if gas exchange parameters from CPET match perfusion defects seen in PETCT imaging. Additionally, patients who undergo invasive coronary treatments will be invited for follow-up tests to assess recovery. Participants will perform CPET on a cycle ergometer on a separate day following their PETCT scan. Those receiving coronary artery bypass surgery or percutaneous coronary intervention will be asked to repeat both CPET and PETCT scans six months after treatment. This phase aims to determine if CPET can monitor myocardial perfusion recovery using gas exchange data. During the study, participants undergo PETCT scans and CPET sessions. Researchers will measure the presence of myocardial ischemia using both PET imaging and exercise testing at baseline and six months post-treatment. The study involves regular evaluations of gas exchange and perfusion to gather data on the diagnostic accuracy of CPET and its potential for follow-up assessment.
