폐울혈을 동반한 노인 환자와 무증상 노인군에서의 좌심실 확장기 기능의 평가
The recent studies shows that LV relaxation abnormalities are the important factors of heart failure in elders. To determine the association between LV diastolic functions and heart failure, we assessed LV diastolic functions in elderly patients with pulmonary congestion and in asymptomatic elders by using pulsed doppler echocardiography.
In order to assess LV diastolic function, we performed pulsed doppler echocardiography to elderly patients with pulmonary congestion and asymptomatic elders from Mar.2001 to Sep.2001. The following parameters were used as indices of LV diastolic function; Mitral E wave(E), Mitral A wave(A), Deceleration time(DT), Isovolumic relaxation time(IVRT), Systolic pulmonary venous flow(PVs), Diastolic pulmonary venous flow(PVd).
In elderly patients groups, there was significant increase in deceleration time compared with asymptomatic elders(255.83+/-54.41 vs 210.80+/-48.53, p<0.05). There was significant increase in isovolumic relaxation time in elderly patient group compared with asymptomatic elders(123.06+/-25.07 vs 98.78+/-15.12, p<0.01). Although there was no significant difference, decreased E/A ratio and increased PVs/PVd were noted in both groups.
The results shows that the impairments of LV diastolic function were noted in both groups. Especially DT and JVRT were significant increase in elderly patient group with pulmonary congestion. Therefore these parameters, such as DT, IVRT, can be helpful as predictive indices of diastolic heart failure in elders.
