Altered BP/HR rhythms in renal-failure hypertension may signal autonomic dysfunction; hypothesis-generating and should not yet change practice.
Are the circadian rhythms of blood pressure and heart rate altered in hypertensive patients with chronic renal failure compared to those with essential hypertension?
Hypertensive patients with chronic renal failure exhibit significantly altered circadian rhythms of blood pressure and heart rate compared to those with essential hypertension, likely reflecting autonomic dysfunction.
Portaluppi et al. (1990) studied this question.
