Multivariable‐adjusted means of left atrial volume index (A), e′ (B), and E/e′ (C) at follow‐up by hypertension category at baseline. NT, WHT, MHT, and SHT indicate true normotension and white‐coat, masked, and sustained hypertension, respectively. Estimates given with SE account for clustering within families and were adjusted for sex, the baseline characteristics age, body mass index, heart rate, serum total cholesterol, plasma glucose, γ‐glutamyltransferase (index of alcohol intake) and smoking, for use of lipid‐lowering treatment at follow‐up, for 3 indicator variables coding for starting, stopping, or continuing antihypertensive drug treatment from baseline to follow‐up, and for duration of follow‐up. Left atrial volume index was available in 763 participants and e′ and E/e′ in 780. P values are for the between‐group comparisons. LAVI indicates left atrial volume index.
