Influence of hemodialysis on echocardiographic Doppler indices of the left ventricle: changes in parameters of systolic and diastolic function and Tei index
Why the study?
Does hemodialysis alter the Tei index and other Doppler-derived echocardiographic indices in patients with chronic renal failure?
Population
32 patients with chronic renal failure (21 men and 11 women, aged 48-93 years) on maintenance hemodialysis
Comparison
Hemodialysis vs Pre-hemodialysis baseline
Design
Cohort
Follow-up
Immediate post-hemodialysis

Implication
Clinicians should interpret post-hemodialysis Tei index changes cautiously; leaves open its value as a load-independent myocardial function marker.

Hemodialysis

Comparator
Pre-hemodialysis baseline

Outcome
Change in Tei index and other Doppler-derived indices of systolic and diastolic functionsurrogate
The Tei index is significantly affected by dialysis-induced altered loading conditions, suggesting it is preload-dependent.
