Abstract Objectives Coronary microvascular functional and structural obstructions (CMVO) after percutaneous coronary intervention (PCI) are a major cause of poor clinical outcomes in patients with acute syndrome. This study aimed to noninvasively diagnose the presence CMVO using non-contrast multiparametric cardiac magnetic resonance (CMR) myocardial infarction (AMI) who underwent PCI. Methods We retrospectively enrolled consecutive AMI PCI subsequent acute-phase CMR at our hospital. The were divided into two groups: those without CMVO. top five parameters extracted based on their correlation coefficients Receiver-operator characteristic (ROC) curves area under curve (AUC) generated compare diagnostic performance detection Top_5 parameters, left ventricular (LV) volume structure parameters. Differences AUC between compared DeLong test. Results Forty-eight (40 men 8 women; mean age, 66 ± 12 years) included study. For detection, ROC LV demonstrated AUCs 0.87, 1.00, 0.72, respectively. exhibited highest AUC, showing significant differences other groups. Conclusion Non-contrast enhanced allows diagnosis high accuracy kidney burden is expected be useful marker for risk stratification, patient management, treatment decision-making. Key Points Question following difficult through angiography can lead adverse . Findings imaging has potential accurately CMVOs further identify location extent Critical relevance enables accurate, noninvasive CMVO, provides both organic information. These findings crucial diverse etiologies that require individualized treatment, may help decision-making Graphical
