ANP rhythm assessment remains investigational in hypertension; leaves open its prognostic or therapeutic relevance.
Does the circadian rhythm of ANP differ between normal and hypertensive subjects and how does it relate to other cardiovascular and hormonal variables?
ANP exhibits a distinct circadian rhythm that peaks in the early morning in antiphase to blood pressure and heart rate, with higher overall levels in hypertensive patients.
Portaluppi et al. (1990) studied this question.
