Insights

Coronary arterial calcification (CAC) and spine bone mineral density (vBMD) can be measured from the same scans in early postmenopausal women. Further research is needed to understand changes with age and estrogenic treatments.

Area of Science:

  • Cardiovascular health and bone metabolism in postmenopausal women.
  • Imaging techniques for assessing cardiovascular and bone health.

Background:

  • Cardiovascular disease and osteoporosis are significant health concerns for women after menopause.
  • Aortic calcification is linked to bone loss, but the relationship between coronary arterial calcification (CAC) and bone density is less understood.

Purpose of the Study:

  • To investigate the association between coronary arterial calcification (CAC) and volumetric bone mineral density (vBMD) in women shortly after menopause.
  • To establish a baseline for future studies on estrogenic treatments and their impact on cardiovascular and bone health.

Main Methods:

  • Coronary arterial calcification (CAC) was quantified using 64-slice computed tomography.
  • Volumetric bone mineral density (vBMD) was assessed from the same CT images.
  • Serum and plasma concentrations of bone matrix proteins were measured using ELISA.

Main Results:

  • CAC scores varied, with most women having no or low calcification.
  • A trend suggested lower thoracic bone density with increasing CAC, though not statistically significant.
  • Bone turnover markers were generally within normal ranges and did not correlate with age or time since menopause.

Conclusions:

  • Coronary arterial calcification (CAC) and spine vBMD can be effectively measured from the same scans in women within the first three years post-menopause.
  • Further research is required to understand the longitudinal changes in these parameters with aging and estrogen therapy.

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...

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...
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.
Menopause01:28

Menopause

Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
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.
