The Tromsø Study, 1994–2010.
*p Value for trend is calculated for six groups of LA size and mitral Doppler flow combined. Description can be found in the Methods section.
Model 1: adjusted for age and sex (not in sex-specific models).
Model 2: as Model 1+height, body mass index, hypertension, diabetes, palpitation.
Model 3: as Model 2, participants with coronary heart disease, valvular heart disease, heart failure or hypertrophy at baseline excluded.
Model 4: as Model 1.
Model 5: as Model 2.
Mitral Doppler flow—normal: E/A ratio 0.75–1.5 and E-wave deceleration time (EDT >140 ms; abnormal: E/A ratio <0.75 or >1.5 or EDT <140 ms.
