Myocardial strain parameters detected by tissue tracking on cardiac magnetic resonance (CMR-TT) were helpful for early prediction of myocardial damage in patients with hypertrophic cardiomyopathy (HCM). Global circumferential strain (GCS) and late gadolinium enhancement (LGE) percentage were reliable and independent predictors for ventricular arrhythmias (VAs) in HCM. For patients who can’t undergo the LGE scan, reduced GCS may have potential value to identify HCM patients with the risk of VAs.
