Atrial natriuretic factor in renal failure and posthemodialytic postural hypotension.
Atrial natriuretic factor (ANF) levels were ten times normal in hemodialysis patients before dialysis. ANF was not cleared by the dialyzer membrane but plasma levels decreased 47% by the end of dialysis. Patients undergoing peritoneal dialysis had plasma ANF levels four times normal and had detectable ANF in their dialysate. Hemodialysis patients with a marked fall in BP after dialysis had higher ANF levels (P less than 0.05) and lower norepinephrine (NE) levels (P less than 0.05) associated with a failure to increase NE in response to dialysis. Elevated ANF levels are associated with postdialysis hypotension in hemodialysis patients.
