What are the types of atherosclerotic plaque?
Best insight from top research papers
Atherosclerotic plaques can be classified into different types based on their composition and structure. The types of plaques identified in the abstracts include lipidic (LP), fibrous (FP), calcific (CP), predominantly calcified (APC), predominantly lipid (APL), and fibrotic (APF) plaques . These plaques have distinct mechanical properties and vulnerabilities. Fibrotic plaques are stiffer and stronger, while lipidic plaques are the weakest. Calcified plaques are the stiffest and most prone to rupture . The morphology and mechanical properties of different plaque components play a crucial role in determining plaque vulnerability . Additionally, atherosclerotic plaques contain various cell types, including smooth muscle cells, macrophages, endothelial cells, B cells, T cells, and fibroblasts, among others .

What is Atherosclerotic?5 answersAtherosclerosis is a chronic condition characterized by the accumulation and hardening of fatty materials in the arterial blood vessels, leading to the obstruction of the lumen. It is a multifactorial disease that involves a cascade of events, including excess oxidative and hemodynamic stress, smoking, poor diet, dyslipidemia, hypertension, and diabetes. Atherosclerosis progresses through the formation of atherosclerotic plaques, which are caused by the accumulation of cholesterol, macrophages, foam cells, smooth muscle cells, mineral crystals, and oxidative products in the subendothelial space. These plaques can rupture, resulting in acute thrombotic events. Macrophages, platelets, and monocytes play crucial roles in the progression of atherosclerosis, facilitating the uptake of lipids by macrophages, foam cell formation, lipid-rich core formation, plaque rupture, and thrombus formation. Atherosclerosis is a major cause of morbidity and mortality worldwide, contributing to conditions such as coronary artery disease, cerebrovascular disease, and peripheral arterial disease.
How does the process of formation and evolution of atherosclerotic plaque occur?3 answersThe formation and evolution of atherosclerotic plaque involve several key processes. Endothelial dysfunction, inflammation, and lipoprotein oxidation lead to the activation, death, and necrotic core formation of macrophages and mural cells. The accumulation of cholesterol, macrophages, foam cells, smooth muscle cells, mineral crystals, and oxidative products occurs in the subendothelial space on a dysfunctional endothelium. Cytokines, such as Monocyte Chemoattractant Protein-1, play a role in monocyte recruitment, while oxidized low-density lipoprotein (oxLDL) contributes to foam cell production. The plaque boundary moves at the same speed as the inflammatory tissues near the periphery. A higher flux of oxLDL leads to a decay in plaque growth, while an increase in cytokines flux favors enhanced plaque growth. The process of plaque development and progression involves various cellular components, including low-density lipoprotein, free radicals, chemoattractants, monocytes, macrophages, T-cells, smooth muscle cells, foam cells, and collagen.
What causes arterial plaque build up?3 answersArterial plaque build-up, or atherosclerosis, is caused by the accumulation of fat, cholesterol, and calcium in the walls of arteries. This process is similar to bone formation and involves a balance between bone-forming cells called osteoblasts and bone-destroying cells called osteoclasts. The resulting plaques narrow and stiffen the arteries, obstructing blood flow and leading to heart attack and stroke. While systemic factors like elevated cholesterol and blood pressure play a role in plaque development, the local microenvironment of the arteries also plays a vital role. Factors such as arterial mechanics, matrix remodeling, and lipid deposition influence the susceptibility to plaque development and regulate vascular cell function. Additionally, the composition of the plaque, including the presence of soft lipid plaque and calcification, can affect the risk of plaque rupture and subsequent stroke.
What are the stages of atherosclerosis?4 answersAtherosclerosis progresses through several stages, starting with endothelial dysfunction and followed by the accumulation of lipids, fibrous elements, and calcification, leading to vessel narrowing and activation of inflammatory pathways. The stages of atherosclerosis can be further classified as early atherosclerotic plaque, plaque formation, and plaque rupture. Macrophages, T cells, and neutrophils play important roles in the inflammatory process of atherosclerosis. Recent transcriptomic analyses have identified different macrophage populations in atherosclerotic lesions, including resident, inflammatory, and foamy macrophages. Understanding the trafficking, fate, and functional aspects of these macrophage populations is crucial in the development of therapeutic approaches to prevent lesion growth and promote plaque regression.
What is the atheromatous plaque composed of?3 answersAtheromatous plaque is composed of various elements including smooth muscle cells, calcium, cholesterol, lipids, and oxidized lipids.The plaque structure consists of layers of hydroxyapatite crystals, cholesterol, and lipid nuclei, which reflect different stages of plaque formation.Spectroscopic imaging techniques such as IR, Raman, and CARS microscopy can be used to identify and quantify the composition of atherosclerotic plaques, providing insights into individual disease patterns.The interaction between blood and plaque leads to the generation of specific molecules in the serum, such as oxidized products of cholesterol (oxysterols), which can serve as biomarkers for plaque status and vulnerability.Understanding the composition of atheromatous plaque is crucial for assessing plaque vulnerability and making appropriate treatment decisions.
Which bacteria are responsible for plaque?2 answersPlaque is primarily caused by bacterial colonization. The bacteria responsible for plaque include Streptococcus sanguinis, Staphylococcus aureus, Actinomyces odontolyticus, Prevotella intermedia, Porphyromonas gingivalis, Peptostreptococcus micros, Streptococcus mutans, Streptococcus mitis, and Streptococcus salivarius. These bacteria produce secondary metabolites, such as alkaloids, flavonoids, glycosides, saponins, tannins, and triterpenoids/steroids, which contribute to plaque formation and the development of periodontal disease. Gram-positive and gram-negative bacilli or cocci have been isolated from dental plaque and gingivitis, indicating their role in plaque formation and gingival destruction. Additionally, red autofluorescence of plaque is associated with species such as Actinomyces odontolyticus, Prevotella intermedia, Porphyromonas gingivalis, and Peptostreptococcus micros, suggesting their involvement in plaque development. Furthermore, ureolytic bacteria, including Streptococcus salivarius and Staphylococcus epidermidis, contribute to urea metabolism in plaque.
