Atherosclerosis I: Introduction01:30

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 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)...
The Oral Microbiota01:27

The Oral Microbiota

The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
Coronary Artery Disease II: Pathophysiology01:26

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 III: Management01:26

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...

Severe periodontitis is linked to carotid atherosclerosis. This suggests periodontal disease may indicate a higher risk for atherosclerotic disease development.

Area of Science:

  • Cardiovascular Health
  • Oral Medicine
  • Medical Research

Background:

  • Poor oral health, specifically periodontitis, is increasingly linked to cardiovascular diseases.
  • Periodontitis is implicated in the pathogenesis of atherosclerosis, a key factor in cardiovascular events.

Purpose of the Study:

  • To investigate the relationship between the severity of periodontitis and the degree of carotid atherosclerosis.
  • To evaluate carotid intima-media thickness (IMT) and atherosclerotic plaques in relation to periodontal health.

Main Methods:

  • Fifty adult patients underwent carotid duplex scans measuring IMT and assessing atherosclerotic plaques.
  • Patients were categorized into test (IMT ≥ 1 mm or plaque presence) and control groups (IMT < 1 mm, no plaque).
  • Periodontal evaluation used clinical attachment level to classify periodontitis as slight, moderate, or severe.

Robust Ligature-Induced Model of Murine Periodontitis for the Evaluation of Oral Neutrophils

Published on: January 21, 2020

Main Results:

  • 70% of patients were in the test group (atherosclerosis present), 30% in the control group.
  • Severe periodontitis was diagnosed in 40% of all patients.
  • A significant association was found between more severe periodontitis and the presence of atherosclerosis (P = 0.007).

Conclusions:

  • The study demonstrates a clear association between the severity of periodontitis and carotid atherosclerosis.
  • Periodontal disease may serve as a valuable risk indicator for developing atherosclerotic disease.
