    Insights

    Atherosclerosis is common in patients with ischemic heart disease, affecting both coronary and carotid arteries. Non-invasive imaging like CT and ultrasound can help screen for these arterial changes.

    Area of Science:

    • Cardiovascular Medicine
    • Diagnostic Imaging
    • Vascular Biology

    Background:

    • Ischemic heart disease (IHD) is a major health concern.
    • Atherosclerosis affects multiple arterial beds, including coronary and carotid arteries.
    • Understanding the prevalence and correlation of atherosclerotic changes is crucial for patient management.

    Purpose of the Study:

    • To determine the prevalence of atherosclerotic changes in coronary arteries (via CT) and carotid arteries (via ultrasound duplex scanning - UDS) in IHD patients.
    • To analyze the viscoelastic properties of common carotid arteries and their correlation with UDS and CT findings.
    • To identify predictors of coronary calcification.

    Main Methods:

    • Computed tomography (CT) and ultrasound duplex scanning (UDS) were performed on 100 patients with verified IHD.
    • Measurements included coronary calcium index (MCCI) and intima-media thickness (IMT) of common carotid arteries.
    • Viscoelastic properties of carotid artery walls were assessed.

    Main Results:

    • High prevalence of coronary calcifications (96%) and carotid artery atherosclerosis (89%) was observed.
    • A significant correlation was found between coronary MCCI and carotid IMT.
    • Increased carotid IMT and atherosclerotic plaques (ASP) were predictors of coronary calcification.
    • Carotid artery walls in IHD patients showed increased stiffness compared to healthy subjects.

    Conclusions:

    • Combining CT and UDS provides comprehensive information on atherosclerotic changes in IHD patients.
    • Non-invasive measures like carotid IMT, carotid ASP detection, and coronary MCCI can serve as screening tools for coronary atherosclerosis.
    • These findings support the use of non-invasive imaging for early detection and risk stratification in IHD.

    Ischemic Heart Disease: Overview01:17

    Ischemic Heart Disease: Overview

    Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
    Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and narrowing...

    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...

    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)...

    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 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...
