[Relationship between sex hormone levels and blood calcitonin gene-related peptide/endothelin-1 in postmenopausal women with coronary heart disease]

What Was Tested

Researchers studied Endothelin-1 and CGRP (Calcitonin Gene-Related Peptide) in this randomized controlled trial publication.

To investigate the relationship between sex hormone levels and blood calcitonin gene-related peptide/endothelin-1, and to evaluate the therapeutic effects of nylestriol.

Who Took Part

The abstract describes 30 women taking part.

The age groups tagged for this paper are middle-aged adults, women only.

How the Study Was Run

In design terms this was a randomized and placebo-controlled study.

The women were allocated by chance, so the Endothelin-1 group and the comparison group should start out alike.

Some women received a placebo instead of Endothelin-1, giving a reference point.

Serum 17 beta-estradiol (E2), testosterone (T), plasma calcitonin gene-related peptide (CGRP) and endothelin-1 (ET-1) were measured.

What Was Measured

Topics PubMed links to this paper include Calcitonin Gene-Related Peptide, Coronary Disease, Endothelin-1, Estradiol, Estradiol Congeners, Postmenopause and Quinestrol.

What This Means in Plain Language

The paper is a randomized and placebo-controlled study of Endothelin-1 and CGRP (Calcitonin Gene-Related Peptide) in 30 women.

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.

Its findings take up roughly 3 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 2001 (Hunan yi ke da xue xue bao = Hunan yike daxue xuebao = Bulletin of Hunan Medical University), a journal based in China.
