[Abstract] Objective: Using cardiac magnetic resonance tissue tracking (CMR-TT) to evaluate the normal range of longitudinal strain and strain rate in the right ventricular myocardium of healthy Chinese people, and to analyze its relationship with age and gender.Materials and Methods: A cohort of 100 healthy subjects from each decade of life between the 20 and 70 in first hospital of China Medical University without known congenital or acquired cardiovascular disease, hypertension, diabetes, dyslipidaemia and systemic inflammatory disorders underwent CMR-TT assessment of right ventricular (RV) myocardial strain and strain rate. Their LV systolic and diastolic function were normal.Results: Global longitudinal strain (GLS) (-24.2±4.6)%, female vs male [(-24.7±5.3)% vs (-23.5±3.6)%, P>0.05]; the correlation between global longitudinal strain and age P>0.05, longitudinal systolic strain rate (GLS S')-1.6±0.6(1/s), female vs male [-1.7±0.6(1/s) vs-1.5±0.7(1/s), P>0.05]; longitudinal diastolic strain rate (GLS D')1.3±0.4(1/s), female vs male [1.3±0.3(1/s) vs 1.4±0.4(1/s), P>0.05]; the correlation between longitudinal systolic strain rate and age P>0.05; the correlation between longitudinal diastolic strain rate and age P>0.05.Conclusions: The normal value ranges of longitudinal strain and strain rate of the right ventricular myocardium in healthy Chinese people were acquired using cardiac magnetic resonance tissue tracking. And the longitudinal strain and strain rate in the right ventricular myocardium have no correction with age and gender. Therefore the normal values of longitudinal strain and strain rate can be a sensitive standard for the clinical pre-diagnosis.
