[Increase by ANP and ADH of the duration of activation and deactivation of the cardiopulmonary baroreceptor reflex: modification in the presence of left ventricular hypertrophy].

What Was Tested

Researchers studied Atrial Natriuretic Factor in this randomized controlled trial publication.

The involvement of cardiopulmonary and arterial sinoaortic receptors in the control of antidiuretic hormone (ADH) and atrial natriuretic peptide (ANP) release is still controversial in humans.

Moreover, it is not clear if this control may be impaired in hypertensive patients with left ventricular hypertrophy (LVH).

Who Took Part

According to the abstract, 17 subjects were involved.

By PubMed's age tags, the people studied were teenagers, adults and middle-aged adults, men only.

How the Study Was Run

The design is described as randomized.

Because people in this Atrial Natriuretic Factor study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Cuff arterial pressure was measured every 5 min, while heart rate was evaluated by continuous ECG recording.

What Was Measured

Blood samples were taken at the end of every step for measurement of ADH, ANP, PRA, immunoreactive renin, aldosterone, noradrenaline and adrenaline.

PubMed files the paper under topics including Atrial Natriuretic Factor, Blood Pressure, Cardiomegaly, Electrocardiography, Heart, Heart Ventricles and Lung.

What This Means in Plain Language

The paper is a randomized study of Atrial Natriuretic Factor in 17 subjects.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

The publication is from 1990 (Cardiologia (Rome, Italy)), a journal based in Italy.
