title: Clinical significance of the urinary oxygen tension in patients with ischemic heart disease.
abstract: The clinical significance of the urinary oxygen tension (PuO2) was evaluated in 60 patients with ischemic heart disease. The PuO2 had fair relations to cardiac index and serum creatinine level (r = 0.73 and r = 0.73, respectively). Although the PuO2 had a fair relation to serum creatinine in patients with a low cardiac index, there was no relation to the cardiac index. In patients with increases in PuO2 from day 1 to day 2, the cardiac index increased, and the serum creatinine level decreased on the 2nd day, whereas a sustained decrease in cardiac index and an increase in serum creatinine were observed in patients with a decrease in PuO2 from day 1 to day 2. Thus, PuO2 can be used as an indicator of the renal function in patients with ischemic heart disease.
