Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers01:19

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

229
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

99
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

133
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Area of Science:

  • Cardiovascular Medicine
  • Pathophysiology
  • Biomarker Discovery

Background:

  • Plaque erosion is a significant cause of acute coronary syndrome (ACS).
  • The underlying biological mechanisms and reliable biomarkers for plaque erosion are not fully understood.
  • Current knowledge gaps hinder the development of effective diagnostic and therapeutic strategies.

Purpose of the Study:

  • To review the current understanding of plaque erosion.
  • To identify potential biomarkers associated with plaque erosion.
  • To explore the pathophysiological differences between plaque erosion and other ACS causes.

Main Methods:

  • Literature review of recent studies on plaque erosion.
  • Analysis of pathophysiological characteristics, including inflammatory responses and immune cell infiltration.
  • Examination of molecular expression patterns in culprit lesions and thrombi.

Main Results:

  • Plaque erosion exhibits distinct inflammatory profiles and immune cell infiltration patterns.
  • Unique molecular expression differences are observed in erosion-related lesions.
  • These findings suggest specific underlying mechanisms driving plaque erosion.
  • Potential biomarkers have been identified that may aid in early detection.

Conclusions:

  • Understanding the specific immune cell roles and biomarkers in plaque erosion is critical for targeted therapy development.
  • Biomarker identification can facilitate early detection and treatment of erosion-prone plaques.
  • This could potentially reduce the incidence of acute coronary events.
