Hpa II polymorphism of the atrial natriuretic peptide gene and the blood pressure response to salt intake in normotensive men

What Was Tested

The paper reports a study of ANP (Atrial Natriuretic Peptide) in the context of low blood pressure and orthostatic hypotension, published as a randomized controlled trial.

To test the hypothesis that the Hpa II variant of the atrial natriuretic peptide gene (ANP), which has been reported to be more common among black hypertensives than it is among normotensive controls, is related to the response of blood pressure to salt intake in normotensive Caucasians.

Who Took Part

The age groups tagged for this paper are adults, men only.

How the Study Was Run

The researchers set it up as a randomized, double-blind, placebo-controlled and crossover study.

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

Blinding on both sides kept the participants and researchers unaware of who received ANP (Atrial Natriuretic Peptide).

The comparison arm used a placebo, so changes seen with ANP (Atrial Natriuretic Peptide) could be set against what happens without it.

In the crossover set-up each of the participants took both ANP (Atrial Natriuretic Peptide) and the comparison in turn, acting as their own control.

The genotype was determined by amplification of genomic DNA extracted from peripheral leukocytes and subsequent digestion of the amplicon with Hpa II restriction enzyme.

What Was Measured

The subject headings attached to it are Alleles, Atrial Natriuretic Factor, Base Sequence, Blood Pressure, DNA Primers, Deoxyribonuclease HpaII and Diet, Sodium-Restricted.
