Coronary microvascular dysfunction
coronary angiography
Patients should undergo coronary angiography to confirm the absence of significant coronary stenosis. Angio-IMR was calculated based on the angiography.
Non-Coronary microvascular dysfunction
coronary angiography
Patients should undergo coronary angiography to confirm the absence of significant coronary stenosis. Angio-IMR was calculated based on the angiography.
