Atherosclerosis III: Management01:26

Atherosclerosis III: Management

12
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

13
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)...

Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

9
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...

Atherosclerosis IV: Nursing Management

21
Nursing management for a patient with arteriosclerosis involves a comprehensive approach focusing on lifestyle modification, disease monitoring, education, and symptomatic care. Here is an overview of effective nursing strategies:Assessment and Monitoring: Initial and ongoing assessments are crucial. Nurses must document the patient's medical history, including any hypertension, diabetes, hyperlipidemia, and other cardiovascular diseases. Assessments also cover family history and lifestyle...

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...

Area of Science:

  • Cardiovascular Biology
  • Molecular Medicine
  • Genetics and Epigenetics

Background:

  • Atherosclerosis is a leading global cause of death, characterized by plaque formation involving endothelial cells, vascular smooth muscle cells, and macrophages.
  • MicroRNAs (noncoding RNA) are critical regulators of gene expression, influencing cell proliferation, apoptosis, and metabolism.
  • Emerging research highlights the significant involvement of microRNAs in the pathogenesis of atherosclerosis.

Purpose of the Study:

  • To review and summarize the multifaceted roles of microRNAs in atherosclerosis.
  • To explore the function of microRNAs in endothelial cells, vascular smooth muscle cells, and macrophages within the context of atherosclerosis.
  • To assess the potential of microRNAs as diagnostic biomarkers and therapeutic targets for atherosclerosis.

Main Methods:

  • Comprehensive literature review of PubMed-indexed articles published before June 2022.
  • Keywords used: "atherosclerosis," "microRNA," "endothelial cells," "vascular smooth muscle cells," "macrophages," and "cholesterol homeostasis."
  • Synthesis of research findings on microRNA functions in atherosclerosis pathogenesis.

Main Results:

  • Significant alterations in microRNA expression levels observed across different stages of atherosclerosis.
  • MicroRNAs implicated in regulating endothelial dysfunction, plaque stability, and cholesterol metabolism.
  • Evidence suggests microRNAs are integral to core processes of atherosclerosis development.

Conclusions:

  • MicroRNAs represent promising novel diagnostic biomarkers for atherosclerosis.
  • MicroRNAs demonstrate substantial potential as therapeutic targets for managing atherosclerosis.
