Insights

Atherosclerosis, a leading cause of death, involves arterial wall changes initiated by endothelial dysfunction and infection. Understanding atherogenesis, lesion development, and thrombotic complications is crucial for developing effective treatments.

Area of Science:

  • Cardiovascular Science
  • Pathology
  • Immunology

Background:

  • Atherosclerosis is the leading cause of death globally, necessitating a deep understanding of its pathogenesis.
  • This review focuses on the cellular and molecular events within the arterial wall during atherogenesis, excluding classical risk factors.
  • Key areas include endothelial dysfunction, infection, lesion development, cellular interactions, and thrombotic complications.

Purpose of the Study:

  • To summarize current knowledge on the pathogenesis of atherosclerosis.
  • To elucidate the cellular and molecular mechanisms underlying atherogenesis within the arterial wall.
  • To discuss the role of endothelial dysfunction, infection, and cellular interactions in lesion development and thrombotic complications.

Main Methods:

  • Literature review and synthesis of existing research on atherosclerosis.
  • Focus on cellular and molecular events within the arterial wall.
  • Analysis of mechanisms leading to atherosclerotic lesion development and thrombotic occlusion.

Main Results:

  • Endothelial dysfunction and infection are key initiators of atherosclerotic lesions.
  • Lesion development involves complex interactions between various cell types within the arterial wall.
  • Understanding these processes is critical for comprehending thrombotic occlusions causing heart attack and stroke.

Conclusions:

  • Atherogenesis is a complex process involving endothelial dysfunction, infection, and intricate cellular interactions.
  • Further research into these mechanisms, aided by animal models, is essential for combating atherosclerosis and its life-threatening complications.

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...

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...

Peripheral Artery Disease I: Introduction

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...

Coronary Artery Disease I: Introduction

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...

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)...
