The correlations have been adjusted for the effects of age, gender, ethnicity, their interactions, and BMI.
%G, percentage of genetic contribution to the phenotypic tracking correlation. * = dismissed from the final model.
IVSD; interventricular septum in diastole; LVPWD; left ventricular posterior wall in diastole; LVIDD, left ventricular internal diameter in diastole; RWT, relative wall thickness; LVMI, left ventricular mass index (LVM/height 27)
