Insights

Large artery stiffening, a marker of vascular aging, is accelerated in HIV infection. This may be due to shared risk factors and the effects of HIV and antiretroviral therapies, increasing cardiovascular disease risk.

Area of Science:

  • Cardiovascular Science
  • Infectious Disease
  • Aging Research

Background:

  • Large artery stiffening is a key indicator of vascular aging.
  • Vascular aging and atherosclerosis are interconnected, sharing common causes.
  • Artery stiffening elevates cardiac workload and reduces coronary blood flow, contributing to cardiovascular disease.

Purpose of the Study:

  • To explore the acceleration of large artery stiffness and vascular aging in HIV-infected individuals.
  • To investigate the role of cardiovascular risk factors, HIV's biological impact, and antiretroviral therapies in this acceleration.

Main Methods:

  • This study reviews existing evidence on vascular aging and HIV.
  • It examines the interplay between HIV, cardiovascular risk factors, and antiretroviral treatments.
  • Analysis focuses on large artery stiffness as a primary outcome measure.

Main Results:

  • HIV infection is associated with accelerated large artery stiffness and vascular aging.
  • High prevalence of cardiovascular risk factors in HIV patients contributes to this.
  • HIV's direct effects and antiretroviral therapy side effects appear to exacerbate artery stiffening.

Conclusions:

  • Large artery stiffness is accelerated in HIV-infected patients.
  • Further research is needed to evaluate therapies for managing artery stiffness in this population.
  • Understanding these mechanisms is crucial for preventing cardiovascular disease in HIV patients.

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

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...

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
Vascular Resistance01:20

Vascular Resistance

Vascular resistance is a critical concept in understanding blood flow dynamics in the circulatory system. It refers to the resistance that blood encounters as it flows through the blood vessels. This resistance is a key factor in determining blood pressure and cardiac workload.
The primary determinants of vascular resistance are vessel diameter, blood viscosity, and vessel length. Among these, vessel diameter plays the most significant role due to the fourth power relationship described by...
Hypertension II: Pathophysiology01:29

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
Sexually Transmitted Infections01:26

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
