長期ペーシング患者における腎血行動態の推移

PSP試験15分値による観察

抄録

Renal function in 36 patients under long-term pacing (average 35.2 mos) was examined by the phenolsulfonphthalein test. These patients were divided into 4 groups depending on the values of PSP at 15 min.
At initial pacing 19 patients had a value of 25%. After long-term pacing 13 of them still showed values over 25% (group A). In the remaining 6 patients the value had decreased (group B).
Seventeen patients had values under 25% at initial pacing. After long-term pacing 7 had values over 25% (group C), and 10 patients still had values under 25% (group D).
With improved cardiac function just after pacing, the values in group A were maintained, but in group B the values during long-term pacing declined due to aging and complications such as arteriosclerotic changes, diabetes mellitus, hypertention, and the like.
Long-term pacing in group C improved cardiac function, causing an increase in renal plasma flow, resulting in improved the values after a few months.
Most patients in group D have some degree of renal disturbance. Therefore the 15 min value of PSP test was low.
