    Insights

    Atherosclerosis complications may stem from engineering fatigue due to blood flow, not just lipid accumulation. Animal models support this fatigue hypothesis, suggesting hemodynamics play a key role in disease development.

    Area of Science:

    • Cardiovascular Science
    • Biomedical Engineering
    • Pathology

    Background:

    • Atherosclerosis involves vessel wall changes, but focus on lipid accumulation overshadows other aspects like complications.
    • The prevailing lipid hypothesis inadequately explains atherosclerosis localization and complications.

    Purpose of the Study:

    • To propose and investigate the engineering fatigue thesis for atherosclerosis.
    • To determine the role of hemodynamics in atherosclerosis development and complications.

    Main Methods:

    • Utilizing animal models with induced disturbances in blood flow.
    • Observing morphological similarities to human atherosclerosis and its complications.

    Main Results:

    • Animal models with disturbed hemodynamics showed accelerated development of atherosclerosis-like disease and complications.
    • Hemodynamics appear to influence dietary lipid accumulation, but combined factors do not fully replicate human atherosclerosis.

    Conclusions:

    • The engineering fatigue hypothesis, driven by hemodynamics, offers a plausible explanation for atherosclerosis and its complications.
    • Hemodynamics are a critical factor in atherosclerosis, potentially more so than previously recognized by lipid-centric models.

    Arteries and Arterioles

    Arteries, the vasculature responsible for transporting blood from the heart, possess robust walls capable of enduring the elevated pressures exerted by the heartbeat. Arteries near the heart are especially thick-walled and enriched with elastic fibers across their three tunics, classifying them as elastic or conducting arteries. These arteries, usually with a diameter exceeding 10 mm, are characterized by their ability to dilate in response to the blood pumped from the heart's ventricles and...
    Vascular Resistance01:20

    Vascular Resistance

    Vascular resistance is a critical concept in understanding blood flow dynamics in the circulatory system. It refers to the resistance that blood encounters as it flows through the blood vessels. This resistance is a key factor in determining blood pressure and cardiac workload.
    The primary determinants of vascular resistance are vessel diameter, blood viscosity, and vessel length. Among these, vessel diameter plays the most significant role due to the fourth power relationship described by...

    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...
    Hypertension II: Pathophysiology01:29

    Hypertension II: Pathophysiology

    Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

    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 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)...
