Myocardial Viability Testing in Patients with Ischemic Cardiomyopathy

Ischemic cardiomyopathy (ICM) is an important cause of heart failure with reduced ejection fraction. Despite the improvement of treatment methods, it still has a high mortality. Coronary revascularization is an important treatment for ICM patients, due to the fact that ICM patients are elderly, have multiple diseases and severe coronary artery lesions, the risk of revascularization is relatively high. Currently, there is still controversy over whether and how to revascularization in ICM patients. Myocardial viability has predictive value for the prognosis of ICM patients and provides reference for selecting treatment strategies, but its guiding value for revascularization in ICM patients still needs further verification. This article provides a review of the current treatment of ICM patients, commonly used methods for myocardial viability assessment, and the clinical application of myocardial viability to guide revascularization, so as to provide reference for clinical work.
