Summary

This study aims to evaluate the sensitivity and specificity of a multi-sensor wireless pressure microcatheter for the diagnosis of CMD in patients with ANOCA/INOCA, using quantitative myocardial perfusion imaging of cardiac magnetic resonance (CMR) as a reference.

Detailed description

This is a prospective, multicenter, single-group target value study, which aims to enroll patients with angina symptoms or objective evidence of myocardial ischemia, whose coronary angiography visual assessment shows a diameter stenosis of \<50% and an FFR \>0.8 (or cRR \>0.89).

Conditions

• Coronary Microvascular Dysfunction (CMD)
