Interdialytic blood pressure is independent of weight gain and correlated with serum angiotensin II levels in adults

in two-thirds of the patients. Angiotensin II (pg/mL) was higher (p = 0.016) in group C (231.5 ± SD 127.8) than in group A patients (105.3 ± 46.5) and was positively correlated with CO (p = 0.002) and with idABP (p = 0.027). There were no significant differences in IDWG among the patient groups. idABP, Δ BP, CO, and SVR were unrelated to IDWG. Males had a higher (p = 0.045) systolic idABP than females. Results suggest that angiotensin II drives idABP independently of IDWG.
