Abstract:
Objectives:To explore the cardiac magnetic resonance(CMR)features of early ventricular aneurysm formation in patients with acute anterior myocardial infarction. Methods:One hundred and eight patients with acute anterior myocardial infarction who underwent primary percutaneous coronary intervention and completed CMR scans within two weeks were retrospectively analyzed and divided into non-ventricular aneurysm group(n=72)and ventricular aneurysm group(n=36)according to the absence or presence of early ventricular aneurysm after primary percutaneous coronary intervention.The obtained CMR images were imported into CVI42 software for image analysis,and a logistic regression analysis model was established to evaluate CMR features useful for the diagnosis of early ventricular aneurysm formation. Results:Aging and larger area of late gadolinium enhancement(LGE)and worse left ventricular systolic function and lower myocardial strain were features of patients in the ventricular aneurysm group as compared to the non-ventricular aneurysm group.LGE area(OR=1.32,95%CI:1.071-1.628,P=0.009),apical angle(OR=1.24,95%CI:1.041-1.475,P=0.016),septal mitral annular plane systolic excursion(septal MAPSE,OR=0.36,95%CI:0.169-0.757,P=0.007)and global longitudinal strain(GLS,OR=0.53,95%CI:0.154-0.953,P=0.046)were associated with early ventricular aneurysm formation.ROC curves were analyzed for the above four CMR parameters,and the AUC were 0.922,0.921,0.905,and 0.814,respectively.The optimal cutoff values were 28.5%,90°,8.245 mm,and 10.155%,respectively. Conclusions:Estimation of LGE area,apical angle,septal MAPSE and GLS using CMR technique can help diagnose early ventricular aneurysm in patients with acute anterior myocardial infarction.
