About this trial
We will establish a cohort of 570 symptomatic chronic coronary syndrome patients undergoing 15O-water PET and assess their symptoms through repeated questionnaires. Two hundred patients with abnormal perfusion will be randomized to immediate or delayed referral to invasive coronary angiography with concomitant optimization of guideline-directed medical therapy with repeated 15O-water PET and questionnaires at 3 and 6 months. The primary objective is to compare the potential benefit of early invasive coronary angiography (ICA) versus guideline directed medical therapy (GDMT) on symptomatic relief defined as freedom of angina after 3 months following a positive \[15O\]H2O cardiac PET/CT in patients with symptomatic chronic coronary syndrome.
