[Serotonin in arterial hypertension]

Area of Science:

• Cardiovascular Medicine
• Neuroendocrinology
• Biochemistry

Background:

• Arterial hypertension and atherosclerosis are significant cardiovascular risk factors.
• Serotonin plays a complex role in cardiovascular physiology and pathology.
• Sex-based differences in cardiovascular disease prevalence and progression are well-documented.

Purpose of the Study:

• To investigate serum serotonin levels in patients with arterial hypertension and atherosclerosis.
• To explore potential differences in serotonin levels between sexes in these patient groups.
• To identify correlations between serotonin levels and hypertension/atherosclerosis status.

Main Methods:

• Blood samples were collected from 67 patients (39 with hypertension, 28 with normal pressure).
• Patients were categorized into three groups based on atherosclerosis, hypertension status (systolic, systolic-diastolic), and sex.
• Serum serotonin levels were quantified and compared across the defined patient groups.

Main Results:

• The highest serotonin values were observed in males with diagnosed atherosclerosis, particularly those with systolic or systolic-diastolic hypertension.
• Patients with hypertonic disease (Stage II) complicated by atherosclerosis also showed elevated serotonin levels, especially in males.
• Serotonin levels appeared relatively lower in females diagnosed with hypertonic disease and atherosclerosis.

Conclusions:

• Elevated serotonin levels are associated with atherosclerosis and hypertension, particularly in males.
• Significant sex-based differences in serotonin levels exist within these patient cohorts.
• Further research into female humoral factors is warranted to explain observed serotonin level discrepancies.
