Why the study?
Risk stratification after AMI has traditionally focused on LV dysfunction, while right heart myocardial deformation—particularly RA strain—remains limited and overlooked.

Editorial
Key result
Incorporating right atrial and right ventricular strain parameters into post-AMI risk models may improve risk discrimination and refine the identification of patients at high risk for adverse outcomes.

Should incorporate RV assessment into post-AMI risk stratification; extends LV-only models with randomized CMR evidence.
Incorporating right heart strain parameters, particularly right atrial and right ventricular deformation via cardiac MRI, may improve post-AMI risk stratification beyond traditional left ventricular indices.
Dai et al. (2026) conducted an editorial in Acute Myocardial Infarction. Right heart strain assessment was evaluated. Incorporating right atrial and right ventricular strain parameters into post-AMI risk models may improve risk discrimination and refine the identification of patients at high risk for adverse outcomes.
