This study evaluated the right ventricular (RV) myocardial strain of Hypertrophic Cardiomyopathy (HCM) patients with preserved ejection fraction (EF) and without myocardial hypertrophy in RV based on Cardiovascular magnetic resonance feature tracking technique (CMR-FT), and further explored the effect of left ventricular (LV) myocardial mechanics on the RV. The results showed that the global longitudinal strain (GLS) of the RV has been impaired, although the structure and EF of the RV were normal, so myocardial strain can be more sensitive and earlier to identify cardiac impairment. The systole function of the LV has a great influence on the RV function.
