Insights

Aortic calcifications increase with age and are linked to osteoporotic fractures. Their progression also correlates with bone mineral density loss in the lumbar spine.

Area of Science:

  • Gerontology
  • Cardiovascular Health
  • Bone Health

Background:

  • Osteoporosis and aortic calcification are common in individuals over 50.
  • The relationship between abdominal aortic calcification progression and osteoporosis requires further investigation.

Purpose of the Study:

  • To analyze the association between abdominal aortic calcification progression and osteoporosis in Spanish men and women over 50.
  • To explore the link between aortic calcifications and osteoporotic fractures.

Main Methods:

  • Prospective study of 624 men and women aged 50+ followed for 4 years.
  • Evaluated thoracic and lumbar spine X-rays, dual X-ray absorptiometry (DXA) of lumbar spine and hip.
  • Classified abdominal aortic calcifications as absent, mild-moderate, or severe.

Main Results:

  • Aortic calcification prevalence positively correlated with age.
  • Severe aortic calcifications were associated with osteoporotic fractures (OR=1.93), particularly vertebral fractures (OR=2.45).
  • Aortic calcification progression linked to a faster decline in lumbar spine bone mineral density (BMD).

Conclusions:

  • Baseline aortic calcifications are associated with osteoporotic fractures.
  • Progression of aortic calcifications correlates with decreased lumbar spine BMD.

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...
Role of Vitamins in Maintaining Bone Health01:25

Role of Vitamins in Maintaining Bone Health

The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

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...
Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
Bone Remodeling01:40

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
