Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

2.1K
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

905
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

546
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

4.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

Cardiomyopathy III: Hypertrophic Cardiomyopathy

754
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Mitochondria01:37

Mitochondria

21.5K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Summary

Myometrial artery calcifications, a marker of vascular aging, increase with age in women. Uterine tissue sections from hysterectomy specimens are a suitable model for studying these age-related vascular changes.

Area of Science:

  • Gynecology
  • Vascular Biology
  • Pathology

Background:

  • Vascular aging is a significant factor in cardiovascular health.
  • Myometrial artery calcifications are a potential indicator of vascular aging.
  • The utility of uterine tissue in studying vascular aging requires further investigation.

Purpose of the Study:

  • To investigate the association between myometrial artery calcifications and age.
  • To determine if uterine sections are a viable model for studying vascular aging.

Main Methods:

  • An observational study included 172 women aged 45 and older undergoing hysterectomy.
  • H&E-stained uterine sections were analyzed by a pathologist for myometrial artery calcifications.
  • Exclusion criteria included malignancy, undocumented last menstrual period, or unavailable slides.

Main Results:

  • Myometrial artery calcifications were detected in 9.9% of the 172 women studied.
  • The prevalence of calcifications significantly increased with advancing age (P=.022).
  • No calcifications were found in women aged 45-49, while prevalence rose in older age groups.

Conclusions:

  • Myometrial artery calcifications demonstrate a clear increase with advancing age.
  • Histological analysis of hysterectomy specimens offers a useful model for assessing vascular aging markers.
