Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

521
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

4.0K
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...

Bone Disorders01:29

Bone Disorders

5.8K
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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

459
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...

Coronary Artery Disease II: Pathophysiology01:26

Coronary Artery Disease II: Pathophysiology

860
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

1.0K
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Area of Science:

  • Cardiovascular Biology
  • Vascular Medicine
  • Aging Research

Background:

  • Arterial calcification is prevalent, particularly in the aorta, increasing with age and in specific disease states.
  • Calcification can occur in the arterial media, linked to cognitive decline and cardiovascular mortality, resembling premature aging.
  • Arteriosclerosis, the hardening of arteries due to calcium, has been recognized for centuries, but recent advances illuminate its complex biology.

Purpose of the Study:

  • To review recent advances in understanding aortic calcification.
  • To highlight clinical and discovery science findings with translational implications.
  • To discuss the potential for future medical treatments for calcific aortopathy.

Main Methods:

  • Review of burgeoning literature on aortic calcification.
  • Analysis of recent clinical and discovery science findings.
  • Exploration of disease biology, including innate immunity, senescence, and osteogenic mechanisms.

Main Results:

  • Calcific aortopathy involves innate immunity, inflammaging (inflammation and aging), and ectopic osteogenesis.
  • Understanding of aortic calcium deposition has significantly advanced in the last decade.
  • Calcification is associated with accelerated neurocognitive decline and increased cardiovascular mortality.

Conclusions:

  • Significant progress has been made in understanding the causes and consequences of aortic calcification.
  • The next decade holds promise for developing effective medical treatments for calcific aortopathy.
  • Translational research is crucial for bridging discovery science and clinical applications.
