[Arterial media calcification: from pathogenesis to diagnosis]
Summary
Patients with chronic kidney disease (CKD) face higher cardiovascular risks due to arterial media calcification (AMC). Early detection using advanced imaging and understanding calcification pathways can improve treatment for these high-risk individuals.
Area of Science:
- Vascular Biology and Pathology
- Nephrology
- Cardiovascular Medicine
Context:
- Patients with chronic kidney disease (CKD) exhibit elevated cardiovascular mortality.
- Arterial media calcification (AMC) significantly contributes to this increased risk.
- The precise classification of arterial calcification (intimal vs. medial) remains under investigation.
Purpose:
- To explore the multifactorial pathogenesis of arterial media calcification (AMC).
- To review current and emerging imaging modalities for AMC detection in CKD patients.
- To highlight the role of vascular smooth muscle cells (VSMCs) and potential therapeutic targets.
Summary:
- AMC pathogenesis involves oxidative stress, endothelial dysfunction, and VSMC transformation into osteoclast-like cells.
- While X-ray imaging detects advanced AMC, ultrasonography and mammography offer earlier detection.
- Calcium-sensing receptor (CaSR) and vitamin D receptor (VDR) in VSMCs are key players.
Impact:
- Early identification of AMC in CKD patients is crucial for timely intervention.
- Understanding AMC mechanisms may lead to targeted therapies, potentially involving agents like cinacalcet or paricalcitol.
- Improved diagnostic tools and therapeutic strategies can mitigate cardiovascular mortality in CKD.

1.1K
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...

2.5K
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...

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)...

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...

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...
