Abstract
Purpose:Quantitative tissue Doppler imaging(QTVI)for left ventricular(LV) systolic and diastolic function evaluation in old patients with hypertention was studied.Materials and Methods:In 50 old patients with myocardium hypertrophy and in 20 old healthy people with similar age and heart rate,peak systolic velocity(Vs),peak systolic time(Ts),and the peak velocity of LV regional myocardium during early diastole(Ve) and atrial contraction(Va),Ve/Va ratio were assessed and compared by quantitative tissue Doppler imaging.Results:Compared with the healthy people,the patients with hypertension showed lower Ve at anterior,post and inferior walls(P0.01,P0.05) and Va(late diastolic) at post interventricular septum,posterior and inferior walls(P0.05) in mitral valve level,and lower Ve and Va at post interventricualr septum and posterior wall in papillary muscle level(P0.05).The Ve/Va ratio was not significantly different between the two groups(P0.05).Conclusion:QTVI was a rapid,comprehensive,and valuable method to quantitatively assess LV regional diastolic function,but the Ve/Va ratio was of limited value.
