h² _tot = total h² ; h² _spec = specific h² for visit 2; h² _delta = h² for change score between the two visits; * = dismissed from the final model.

All models were adjusted for age, gender, ethnicity, their interactions, and BMI.

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).
