Other
Other related information We will prospectively perform this non-randomized observational study. We will evaluate relationships between improvement in coronary flow reserve (CFR), CFR at baseline, and the following information.
1) Physical measurements
2) Laboratory data results
3) Physiological function testing
4) Questionnaire data and medical records about coronary risk factors
5) Coronary artery calcium score in computed tomography (CT)
6) Imaging tests, including coronary angiography, myocardial perfusion image, cardiac magnetic resonance imaging, coronary CT angiography, and dobutamine stress echocardiography
7) Revascularization, including percutaneous coronary intervention and coronary-artery bypass grafting
8) Antianginal medications
