Correlation of global longitudinal strain parameters with
myocardial function
To assess the correlation of both LV-GS and LA-GS with ventricular
function by traditionally echocardiographic evaluation, we performed
partial correlation analysis to obtain correlation coefficients after
adjusting for age. In order to evaluate the prediction capacity of
global strain on myocardial function, we performed linear regression
analysis to assess the association and variability adjusted for age.
