AccuIMR Predicts Microvascular Obstruction and Infarct Size in STEMI Patients
Angiography-derived Index of Microcirculatory Resistance Predicts Microvascular Obstruction and Infarct Size in Patients With ST-segment-elevation Myocardial Infarction
Source: ClinicalTrials.gov · Last updated 27 Apr 2025
Brief summary (registry, in English)
In this study, we aimed to investigate the clinical significance of the angiography-based IMR calculation method (AccuIMR) and its prognostic assessment capability by evaluating the concordance or discordance between AccuIMR values and cardiac magnetic resonance (CMR) results.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Other
- (1) Suboptimal coronary angiographic images, including inadequate contrast opacification, unsatisfactory projection view, and severe overlap or distortion of the target vessel.
- (2) Lacking two angiographic projections separated by at least 25° apart post-PCI.
- (3) Inadequate CMR image quality
Who the study is looking for
- (1) STEMI patients who underwent PCI within 12 hours of symptom onset.
- (2) coronary microvascular function was assessed using contrast-enhanced CMR after PCI.
