Summary: This study aimed to assess the prognostic value of myocardial salvage index (MSI) by cardiac magnetic resonance (CMR) in ST-segment elevation myocardial infarction (STEMI) patients. The results showed that MSI can predict major adverse cardiovascular events (MACE) in STEMI patients. However, further investigation is needed to evaluate the prognostic value of MSI using advanced CMR techniques for adverse cardiovascular events.

Summary: This study investigates the prognostic value of myocardial salvage index (MSI) in reperfused ST-segment elevation myocardial infarction (STEMI) using a contrast agent-free cardiac magnetic resonance (CMR) technique. The study finds that MSI is negatively correlated with reperfusion time and infarct size (IS), and positively correlated with left ventricular ejection fraction (LVEF). Moreover, the combination of MSI with LVEF has the strongest prognostic value for major adverse cardiovascular events (MACEs).

Summary: Cardiac magnetic resonance (CMR) imaging technology is considered the gold standard for evaluating myocardial function and viability in acute myocardial infarction (AMI). Various CMR techniques can specifically display and evaluate the pathophysiological changes in each stage of AMI. This article reviews the recent advances of CMR technology in AMI and prospects its future development directions.

Summary: Infection with SARS-CoV-2, the virus that causes COVID, can lead to various cardiovascular complications. Cardiac imaging has become crucial in differentiating pulmonary and cardiovascular complications due to the non-specific symptoms and laboratory findings of COVID patients. This review summarizes the existing literature and major societal guidelines to provide an overview of the indications and utility of different cardiac imaging modalities for diagnosing cardiovascular complications of COVID.

Summary: This study established and validated a non-contrast T1 map-based radiomic nomogram for predicting major adverse cardiac events (MACEs) in acute STEMI patients undergoing PCI. The radiomic signature showed good prognostic ability in both training and test sets, while the nomogram combining radiomic scores and cardiac troponin I demonstrated good discrimination ability for predicting MACEs.

Summary: The study found that myocardial scarring size in T2DM patients after MI is negatively correlated with LV global PS and PSSR, particularly in the circumferential direction. Different MI regions have different effects on the reduction of LV deformation, and relevant clinical evaluations should be strengthened.

Summary: This study aimed to evaluate age-related differences in ventricular remodeling after primary percutaneous coronary intervention (PPCI) for ST-segment elevation myocardial infarction (STEMI). The results showed that young patients are more likely to have adverse remodeling and less likely to develop reverse remodeling after PPCI compared with old patients, highlighting the importance of paying equal or more attention to young patients with STEMI.

Summary: Coronary and cardiac imaging of patients with type 2 myocardial infarction identified coronary artery disease in two-thirds of patients and left ventricular systolic dysfunction in one-third of patients. Unrecognized and untreated coronary or cardiac disease is seen in most patients with type 2 myocardial infarction, presenting opportunities for initiation of evidence-based treatments with major potential to improve clinical outcomes.

Summary: The prognostic value of entropy derived from late gadolinium enhancement images on cardiac magnetic resonance (CMR) for major adverse cardiac events (MACE) in post-myocardial infarction (MI) patients was explored. Results showed that the MACE group had higher entropy values compared to the No-MACE group. Specifically, border zone entropy (BZ entropy) and infarct core and peri-infarct border zone entropy (IBZ entropy) were found to be better risk stratification parameters.

Summary: This study aimed to investigate the correlation between increased extracellular matrix estimated by cardiac magnetic resonance (CMR) and left ventricular aneurysm after acute myocardial infarction. The results showed that acute LGE and ECV of the myocardium provided predictive significance for LVA, and the discriminative significance of ECV for functional versus anatomical LVA was better than the discriminative significance of LGE.

Summary: The study aimed to evaluate the potential value of machine learning models using radiomic features from late gadolinium enhancement (LGE) and cine images on magnetic resonance imaging (MRI), along with clinical information and conventional MRI parameters, for predicting major adverse cardiac events (MACE) in ST-segment elevation myocardial infarction (STEMI) patients. A retrospective study included 60 patients with first STEMI, and radiomic features were extracted from cine and LGE images. The neural network algorithm showed the highest predictive performance. The best model, which included clinical parameters, CMRI parameters, and selected radiomic features, had a diagnostic performance with high accuracy and predictive values. The radiomics-based machine learning models incorporating clinical and conventional MRI parameters are promising for predicting MACE occurrence in STEMI patients during follow-up.

Summary: The study aimed to develop a DCNN model that integrates multidimensional CMR data to accurately identify LV paradoxical pulsation after reperfusion by primary percutaneous coronary intervention. The DCNN model showed high accuracy in identifying paradoxical pulsation, and the 2.5D multiview model performed better than the 3D model. The discrimination performance of the DCNN model was superior to that of trained physicians.

Summary: This study evaluated the feasibility of cardiac magnetic resonance (CMR) and the role of myocardial strain in the diagnostic work-up of patients with acute myocardial infarction (AMI) and suspected cardiac rupture (CR). CMR was found to be a safe and effective tool to diagnose CR and visualize tissue abnormalities associated with CR. Strain analysis parameters may provide insights into the pathophysiology of CR and help identify patients with sub-acute CR.
