Abstract |
Thes is a study on changes of plasma renin activity (PRA) and aldosterone concentration (PAC)
which was obtained before and after heart operation in 26 normotensive children with congenital
heart diseases without renal disease admitted in Chungnam National University Hospital for cardiac
catheterization with angiogram and heart operation from Apr. 1988 to Aug. 1988 to confirm any
differences of PRA and PAC between groups and to establish their influencing factors.
The results were as follows:
1) PRA before operation was higher than that in control group and reduced after operation.
2) The increase in PRA correlated inversely with the increase in mean arterial pressure and linearly
with the increase in hematocrit.
3) PRA in group with value of QP/QS above 2.0 was higher than that in group with value of QP/QS
under 2.0.
4) PAC before operation was higher than that in control group and reduced after operation.
5) The increase in PAC correlated inversely with the increase in mean arterial pressure and linearly
with the increase in hematocrit of cyanotic group.
6) The increase in PAC correlated linerrly with the increase in PRA. |
