Echocardiographic Indexes at Follow‐Up in Relation to Baseline Daytime and Follow‐Up Conventional Blood Pressure

Model Echocardiographic Index	Systolic Blood Pressure		Diastolic Blood Pressure
	Follow‐Up Conventional	Baseline Daytime	Follow‐Up Conventional	Baseline Daytime
LV mass index, g/m2	1.44 (0.54–2.33)†	1.60 (0.17–3.04)*	0.55 (−0.24 to 1.33)	0.96 (0.06–1.86)*
LA volume index, mL/m2	0.53 (0.26–0.79)‡	0.45 (0.03–0.88)*	−0.17 (−0.41 to 0.06)	0.38 (0.12–0.65)†
e′ peak, cm/s	−0.04 (−0.14 to 0.05)	−0.11 (−0.26 to 0.04)	−0.20 (−0.28 to −0.12)‡	−0.17 (−0.27 to −0.08)‡
E/e′ ratio	0.19 (0.12–0.26)‡	0.15 (0.03–0.26)*	0.01 (−0.05 to 0.08)	0.08 (0.01–0.16)*

Association sizes (95% confidence interval) express the differences in the echocardiographic indexes associated with a 10‐mm Hg higher systolic blood pressure or a 5‐mm Hg higher diastolic blood pressure. All models included both blood pressure components, account for clustering within families, and were adjusted for sex, the follow‐up characteristics age, body mass index, heart rate, serum total cholesterol, plasma glucose, γ‐glutamyltransferase (index of alcohol intake) and smoking, and use of lipid‐lowering treatment, 3 indicator variables coding for starting, stopping, or continuing antihypertensive drug treatment from baseline to follow‐up, and duration of follow‐up. LV mass index was available in 750 participants, LA volume index in 763, and e′ and E/e′ in 780. E indicates early diastolic peak velocities; e′, early peak velocities of mitral annular movement; LA, left atrial; LV, left ventricular.

Significance of the associations: *P≤0.05; ^† P≤0.01; and ^‡ P≤0.001.
