Atherosclerosis I: Introduction

Atherosclerosis I: Introduction

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 II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

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 III: Management

Atherosclerosis III: Management

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...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease II: Pathophysiology

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...

Summary

Atherosclerosis, a key driver of cardiovascular disease, involves immune cells and cholesterol. Understanding these immune responses is crucial for developing new atherosclerosis treatments.

Area of Science:

Immunology
Cardiovascular Medicine
Pathology

Background:

Cardiovascular disease is a major global health issue, primarily driven by atherosclerosis.
Atherosclerosis is characterized by chronic inflammation in blood vessels, involving immune cells and cholesterol accumulation.
Immune system components, including innate and adaptive responses, play a significant role in atherosclerosis development.

Purpose of the Study:

To explore the intricate involvement of the immune system in the pathogenesis of atherosclerosis.
To investigate how immune responses, triggered by factors like low-density lipoprotein, contribute to disease progression.
To lay the groundwork for novel immunomodulatory therapies for atherosclerosis.

Main Methods:

Analysis of immune cell infiltration in atherosclerotic lesions.
