Insights

Elevated parathyroid hormone (PTH) levels are linked to increased carotid intima-media thickness (CIMT) and reduced aortic distensibility in patients experiencing ischemic cerebrovascular events (ICVE). This study highlights PTH as a potential biomarker for atherosclerosis in ICVE patients.

Area of Science:

  • Cardiovascular Medicine
  • Endocrinology
  • Neurology

Background:

  • Elevated parathyroid hormone (PTH) is linked to cardiovascular risk factors like hypertension and left ventricular hypertrophy, which predispose individuals to ischemic cerebrovascular events (ICVE).
  • Carotid intima-media thickness (CIMT) and aortic distensibility are established early indicators of subclinical atherosclerosis.
  • The association between PTH levels and these atherosclerosis markers in ICVE patients remained uninvestigated prior to this study.

Purpose of the Study:

  • To investigate the relationship between parathyroid hormone (PTH) levels and measures of atherosclerosis, specifically CIMT and aortic distensibility, in patients with ICVE.

Main Methods:

  • The study included 64 patients diagnosed with ICVE and a control group of 50 individuals.
  • Parathyroid hormone (PTH) levels, carotid intima-media thickness (CIMT), and aortic distensibility were measured in all participants.

Main Results:

  • Patients with ICVE exhibited significantly higher PTH levels compared to the control group (p=0.008).
  • PTH levels demonstrated a significant inverse correlation with aortic distensibility (r=-0.420, p=0.001).
  • A significant positive correlation was observed between PTH levels and CIMT (r=0.285, p=0.002).

Conclusions:

  • This study demonstrates that individuals with acute ischemic cerebrovascular events have elevated parathyroid hormone (PTH) levels.
  • The findings indicate an inverse relationship between PTH levels and aortic distensibility, and a positive association with CIMT in ICVE patients.
  • Elevated PTH may serve as a potential biomarker for subclinical atherosclerosis in the context of ischemic cerebrovascular events.

Types of Hormones

Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

Types of Hormones

Hormones are classified into four main groups: steroids, eicosanoids, amino acid-based derivatives, and peptide hormones.
Steroids and eicosanoids fall under the category of lipid-soluble hormones. Steroids are derived from cholesterol and feature four interconnected carbon rings with variable side chains. Notable examples include estradiol from ovaries and testosterone from testes, exemplifying the critical roles of these lipid-soluble hormones in reproductive physiology. Eicosanoids, derived...

Hormonal Regulation01:33

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

The Parathyroid Glands00:59

The Parathyroid Glands

The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...
