[Comparison of left ventricular function in children hemodialyzed with bicarbonate and acetate. An echocardiographic study].
Left ventricular function before and after hemodialysis with acetate (A) and hemodialysis with bicarbonate (B) was investigated in 8 children on regular dialysis treatment. The decrease in left ventricular volume overload is similar in A and B. There is a significant increase in shortening fraction (B: 9,7 +/- 16,1%; p less than 0,05. A: 7,8 +/- 10,9%; p less than 0,05), in velocity of circumferential fiber shortening (Vcf) (B: 30,6 +/- 16,5%; p less than 0,0005. A: 23,5 +/- 16,6%; p less than 0,0025) and in corrected Vcf (B: 19,3 +/- 16,4%; p less than 0,0025. A: 13,6 +/- 11,4%; p less than 0,005). The ratio of pre-ejection period with the left ventricular ejection time (PEP/LVET) is increased significatively only after hemodialysis with bicarbonate. This difference may be due to a better left ventricular function in hemodialysis with bicarbonate than with acetate.
