| [ Summary ] |
Hemodialysis (HD) patients often have nocturnal hypertension, related to different circadian blood pressure patterns, preceding and following HD sessions, resulting in a 93% abnormality rate. ABPM was performed over a 48-hour period on forty-four HD patients, 64 years old, who had been on HD for a mean average of 65 months. There was no significant change in 24-hour ABP pre-or post-HD, but there was a significant decline in 17-hour ABP, post-HD. 5% of subjects displayed extreme-dipper, 7% dipper and 50% inverted-dipper, CTR, plasma concentrations of natriuretic peptides and catecolamine rose in non-dipper, 39% of subjects. Interdialytic weight gain causes poor reproducibility of nocturnal BP decline. |
