Why the study?
LVEF has limited reproducibility, load dependence, and falls late in myocardial dysfunction, prompting evaluation of CMR feature tracking myocardial strain measurements.
Does myocardial strain imaging using feature tracking on cardiac MRI improve the early detection of left ventricular dysfunction compared to conventional LVEF?

May support GLS for earlier dysfunction detection; leaves open prospective validation before practice change.
Does myocardial strain imaging using feature tracking on cardiac MRI improve the early detection of left ventricular dysfunction compared to conventional LVEF?
Myocardial strain imaging via CMR feature tracking is a sensitive tool for early detection of sub-clinical LV dysfunction before LVEF declines.
