Insights

A new method detected increased circulating anuclear carcasses of endothelial cells in patients with acute myocardial infarction and severe angina. This finding, termed endothelaemia, was not observed in milder angina cases.

Area of Science:

  • Cardiovascular Medicine
  • Cell Biology
  • Diagnostic Methods

Background:

  • Endothelial cells play a crucial role in vascular health.
  • Damage to endothelial cells can indicate cardiovascular distress.
  • Quantifying circulating endothelial cell remnants may offer diagnostic insights.

Purpose of the Study:

  • To investigate the presence and significance of circulating anuclear carcasses of endothelial cells (endothelaemia) in patients with acute myocardial infarction and angina pectoris.
  • To evaluate the utility of a novel counting method for detecting endothelaemia.

Main Methods:

  • A new method was employed to count circulating anuclear carcasses of endothelial cells.
  • The study included 105 patients diagnosed with acute myocardial infarction or angina pectoris.
  • Patient groups were categorized based on disease severity.

Main Results:

  • A significant increase in endothelaemia was observed in patients with acute myocardial infarction.
  • Severe cases of angina pectoris also showed a significant rise in endothelaemia.
  • Milder forms of angina (type I-II) did not exhibit a notable increase in endothelaemia.

Conclusions:

  • Elevated levels of circulating anuclear endothelial cell carcasses (endothelaemia) are associated with acute myocardial infarction and severe angina.
  • The novel counting method appears effective in detecting endothelaemia in these conditions.
  • Endothelaemia may serve as a potential biomarker for cardiovascular disease severity.

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
