All strain parameters (6 variables) were calculated by a stepwise multiple linear regression analysis, and several multiple linear regression models were performed with strain parameters or baseline parameters; Model 1, adjusting the stepwise selection as considered with interaction; Model 2, including the main effect term adjusting with baseline parameters such as the age, gender, E velocity, e` velocity, max velocity of aortic valve, ejection fraction by Simpson’s method
All strain parameters were measured by cardiovascular magnetic resonance myocardial tissue tracking
