Why the study?
Are new Doppler techniques (DTI and color M-mode) for assessing left ventricular diastolic function preload-independent in hemodialysis patients?
Population
10 hemodialysis patients (7 with left ventricular hypertrophy)
Comparison
Hemodialysis with ultrafiltration vs Pre-hemodialysis baseline
Design
Cohort
Follow-up
1 day after hemodialysis

May limit DTI and color M-mode use for diastolic assessment in volume-overloaded HD patients; leaves open preload independence in other settings.
Are new Doppler techniques (DTI and color M-mode) for assessing left ventricular diastolic function preload-independent in hemodialysis patients?
Newer Doppler techniques like DTI and color M-mode remain preload-dependent, limiting their utility for assessing LV diastolic function in hemodialysis patients when volume overloaded.
