Do advanced imaging modalities improve the assessment and risk stratification of patients with nonischemic cardiomyopathy compared to conventional two-dimensional echocardiography?
Advanced imaging modalities offer superior capabilities for tissue characterization and risk stratification in nonischemic cardiomyopathy compared to conventional 2D echocardiography.

May enhance risk stratification in nonischemic cardiomyopathy; leaves open whether it improves outcomes over conventional echocardiography.
Cardiomyopathies are practically classified as either ischemic or nonischemic based on the presence or absence of coronary artery disease. Although conventional twodimensional echocardiography can assess left ventricular ejection fraction, wall motion, and diastolic function, it does not fully capture myocardial mechanics or tissue characterization, and does not accurately identify patients with nonischemic cardiomyopathy (NICMP) at risk for sudden cardiac death. This article discusses advanced imaging modalities for assessment of NICMP, namely, three-dimensional echocardiography, strain imaging, cardiac magnetic resonance, cardiac computed tomography, and sympathetic innervation imaging.

Gupta et al. (2015) conducted a review in Nonischemic Cardiomyopathy. Advanced imaging modalities (3D echocardiography, strain imaging, CMR, CCT, sympathetic innervation imaging) was evaluated. Advanced imaging modalities such as 3D echocardiography, strain imaging, and cardiac magnetic resonance provide important information regarding etiology, cardiac mechanics, and prognosis in patients with nonischemic cardiomyopathy.
