No endogenous BP circadian rhythm under unmasking in young normotensives; leaves open its role in hypertension or aging.
Does an endogenous circadian oscillator regulate blood pressure in normotensive young individuals?
Under rigorous unmasking conditions, there is no evidence of an endogenous circadian oscillator regulating blood pressure, unlike heart rate which maintains a circadian pattern.
G.A. Kerkhof (1998) studied this question.
