The purpose of this study was to evaluate the characteristics of mitral annular motion during diastole in 28 normal subjects, 40 @entity1 with prior @entity583 ( @entity583 ), and 23 @entity1 with @entity453 but without prior @entity583 . Mitral annular motion during diastole was obtained from the apex by M-mode echocardiography at the posterior wall of the left ventricle. Determinants of mitral annular excursion during early (MAE-E) and late diastole ( @entity38145 ) were investigated in all subjects. Differences in the MAE-E, @entity38145 , and the @entity38145 :MAE-E ratio were compared among the three @entity1 groups. The Doppler-derived transmitral flow velocity-time integral during early (EI) and late (AI) diastole and mitral annular excursions during diastole were obtained in 55 other @entity1 with a prior @entity583 and in 29 healthy volunteers. The relationships between the @entity38145 :MAE-E ratio and AI:EI ratio in these two groups were studied. The MAE-E was determined mainly by heart rate and left ventricular ejection fraction (LVEF). The @entity38145 was determined only by age. The magnitude of MAE-E was significantly less in @entity1 with a prior @entity583 than in normal subjects (P < 0.01). However, the @entity38145 did not differ among the three groups. The @entity38145 :MAE-E was higher in @entity1 with a prior @entity583 than in normal subjects (P < 0.05), and was significantly correlated with AI:EI in healthy volunteers (r = 0.65, P < 0.001) and in @entity1 with a prior @entity583 (r = 0.50, P < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
