Key result
CMR may improve diagnosis and prognosis for specific subgroups with cardiomyopathy-related HF.
Why the study?
Assessing risk for adverse events in heart failure is challenging due to heterogeneous phenotypic expression of cardiomyopathy, highlighting the potential role of cardiac MRI given the limitations of commonly used imaging modalities.
Cardiac MRI is posited to play a critical role in the diagnosis and prognosis of cardiomyopathy-related heart failure, potentially improving outcomes for specific at-risk subgroups.
May support targeted CMR evaluation in cardiomyopathy HF subgroups; leaves open prospective validation before practice change.
Heart failure affects 1-2% of the adult population and one of the main contributors to its development is cardiomyopathy. Assessing a patient's risk for adverse events in heart failure is challenging and made more difficult by the heterogenous phenotypic expression of the disease. Cardiac MRI has long been a gold standard measure of myocardial function and anatomy due to its high spatial and temporal resolution. More recently, it has been posited to play a more critical role in the diagnosis and prognosis of cardiomyopathy-related heart failure. Given the limitations of more commonly used imaging modalities, increasing the clinical use of cardiac magnetic resonance imaging could potentially improve the prognosis of specific subgroups of patients at risk of adverse cardiac events.

Lahoti et al. (2021) conducted a review in Cardiomyopathy-related heart failure. Cardiac MRI vs. Commonly used imaging modalities was evaluated. Cardiac magnetic resonance imaging could potentially improve the diagnosis and prognosis of specific subgroups of patients with cardiomyopathy-related heart failure.
