Summary
Vascular calcification mechanisms were studied in MGP-deficient mice. Mineral composition and crystal structure evolve over time, offering insights into pathological calcification and potential disease prevention strategies.
Area of Science:
- Biomedical Engineering
- Materials Science
- Cardiovascular Research
Background:
- Vascular calcification is a significant contributor to morbidity in severe diseases.
- Current treatments are limited due to an incomplete understanding of the molecular mechanisms driving vascular calcification.
Purpose of the Study:
- To investigate the physicochemical processes of mineral nucleation and growth in vascular calcification.
- To elucidate the initiation of pathological calcification on the vascular extracellular matrix using a relevant animal model.
Main Methods:
- Utilized an animal model that accurately replicates human medial arterial calcification.
- Employed a combination of material science techniques to analyze mineral evolution over 5 weeks in MGP-deficient mice.
Main Results:
- Observed dynamic changes in mineral composition and crystallinity during medial calcification.
- Identified a sequential formation of mineral phases: initial calcium adsorption, followed by amorphous calcium phosphate, octacalcium phosphate, and finally hydroxyapatite and carbonated apatite.
Conclusions:
- An interdisciplinary approach integrating animal models and materials science provides critical insights into vascular calcification mechanisms.
- Analyzing specific mineral phases, not just overall mineralization, is crucial for diagnosing and potentially preventing vascular calcification-related diseases.

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...

586
Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

571
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...

1.3K
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...

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...
