Abstract

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.

Plain language summary

Lay abstract Heart failure is a condition where the heart is unable to pump out enough blood to meet the body's daily needs. It can affect up to 2% of the adult population. One of the causes of heart failure is an intrinsic disease of the heart muscle, called cardiomyopathy. Assessing a patient's risk for events such as hospitalization and death in heart failure is challenging, and made more difficult by the wide variety of ways a patient can present with heart failure clinically. Cardiac MRI has long been a highly regarded imaging technique for heart function and shape due to the high level of detail it can show. More recently, it has been thought to play a more important role in investigating and predicting the course of cardiomyopathy-related heart failure. Given the limitations of more commonly used measurement techniques, increasing the clinical use of cardiac magnetic resonance imaging would potentially improve the outcomes and quality of life for patients suffering with cardiomyopathy.
