Shanghai Jiao Tong University

Status: Completed

Conditions: Coronary Artery Disease; STEMI - ST Elevation Myocardial Infarction; Microvascular Coronary Artery Disease

Treatments: Diagnostic Test: CMR

Study type: Observational

Identifiers

NCT06947564

Early MYO IMR-CMR

Details and patient eligibility

About

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.

Enrollment: 843 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• (1) STEMI patients who underwent PCI within 12 hours of symptom onset.
• (2) coronary microvascular function was assessed using contrast-enhanced CMR after PCI.

Exclusion criteria

• (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
