Abstract: The global prevalence of type-2 diabetes mellitus (T2DM) has caused harm to human
health and economies. Cardiovascular disease is one main cause of T2DM mortality. Increased
prevalence of diabetes and associated heart failure (HF) is common in older populations, so accurately
evaluating heart-related injury and T2DM risk factors and conducting early intervention
are important. Quantitative cardiovascular system imaging assessments, including functional imaging
during cardiovascular disease treatment, are also important. The left-ventricular ejection
fraction (LVEF) has been traditionally used to monitor cardiac function; it is often preserved or
increased in early T2DM, but subclinical heart deformation and dysfunction can occur. Myocardial
strains are sensitive to global and regional heart dysfunction in subclinical T2DM. Cardiac
magnetic resonance feature-tracking technology (CMR-FT) can visualize and quantify strain and
identify subclinical myocardial injury for early management, especially with preserved LVEF.
Meanwhile, CMR-FT can be used to evaluate the multiple cardiac chambers involvement mediated
by T2DM and the coexistence of complications. This review discusses CMR-FT principles,
clinical applications, and research progress in the evaluation of myocardial strain in T2DM.
