Arterial stiffness as measured by pulse wave velocity (PWV) is a major predictor of cardiovascular disease. Adrenomedullin (AM), a hypotensive peptide, works as a compensatory factor for arterial sclerosis. The aim of this study was to investigate the relationship between PWV and the plasma concentration of AM in risk-loading patients. One hundred and twenty-six inpatients aged 30 to 75 years with or without varying degrees of atherosclerosis were investigated. Patients with heart and/or renal failure were excluded. The PWV was measured using an automatic waveform analyzer, and the plasma AM level was measured using a newly developed, hypersensitive immunoenzymometric assay system. The PWV increased with the increasing number of cardiovascular risk factors and organ damage in the patients. A positive correlation between the PWV and AM level was observed (r=0.375, p<0.0001, n=126). Seventy-four patients were receiving antihypertensive medications; medication did not affect the correlation. Multivariate regression analysis revealed that the PWV was significantly and independently associated with age, systolic blood pressure, and AM level. These results indicate that the plasma AM concentration could serve as a marker of advanced arterial sclerosis as estimated by increased PWV.

The vasodilator peptide adrenomedullin (AM) elicits diuresis and natriuresis and inhibits aldosterone secretion. The aim of this study was to better understand the role of AM in maintaining water and electrolyte balance during chronic salt loading. Male Wistar rats were divided into a high salt (HS) group that received a diet containing 8% sodium chloride (NaCl) and a normal salt group that received a diet containing 0.4% NaCl. Plasma AM concentrations as well as expression of AM mRNA in the adrenal gland and kidney were then measured after 3, 7, 14, and 28 days. After 28 days, sodium and water excretion were significantly higher in HS rats than in control, although blood pressure and fluid volume were not significantly affected. Moreover, although plasma AM remained unchanged for up to 14 days, it was increased 2.5-fold in HS rats after 28 days on a high salt diet, and there were corresponding 3-fold and 1.5-fold increases in the levels of AM mRNA in the adrenal gland and kidney, respectively. At the same time, expression of calcitonin receptor-like receptor mRNA was significantly upregulated in both kidney and adrenal gland, as was expression of receptor activity-modify protein 1 (RAMP1) and RAMP2 mRNA in the adrenals and expression of RAMP3 in kidneys. Taken together, these results suggest that AM plays a role in the regulation of water and electrolyte balance in animals chronically ingesting high levels of salt.

Both adrenomedullin (AM) and angiotensin II (Ang II) are locally-acting hormones in the cardiac ventricles. Previously we reported that AM inhibits Ang II-induced hypertrophy of cultured rat neonatal cardiomyocytes. In this study, we examined whether Ang II affects the gene expression of the AM receptor components of calcitonin-receptor-like receptor (CRLR) and receptor-activity-modifying protein (RAMP) in rat cardiomyocytes. The mRNA levels of RAMP1 and RAMP3 were significantly elevated following 24-h treatment with Ang II without a change of those of RAMP2 and CRLR. AM increased the intracellular cAMP level and the cAMP accumulation by AM was significantly amplified by the 24-h preincubation with Ang II. The effects of Ang II on RAMP1 and RAMP3 expression were abolished by an Ang II type 1 (AT1) receptor antagonist, but not by an AT2 receptor antagonist. Thus, Ang II modulates gene expression of the AM receptor components via AT1 receptor, suggesting alteration of AM actions by Ang II in cultured rat cardiomyocytes. © 2003 Elsevier Science Inc.
