Insights

Elevated plasma endothelin levels are linked to faster coronary artery disease progression in patients with stable angina. Higher endothelin may indicate an increased risk of rapid stenosis development.

Area of Science:

  • Cardiovascular Medicine
  • Endocrinology
  • Biomarkers

Background:

  • Coronary artery disease (CAD) progression is a significant clinical concern.
  • Identifying reliable markers for predicting rapid CAD progression is crucial for patient management.

Purpose of the Study:

  • To investigate the association between plasma endothelin levels and the rate of coronary artery disease progression.
  • To determine if endothelin serves as a predictive marker for rapid stenosis development in patients with stable angina.

Main Methods:

  • Quantitative angiography was used to assess changes in coronary stenosis diameter over time.
  • Plasma endothelin levels were measured using radioimmunoassay in patients with chronic stable angina.
  • Patients underwent two angiographic assessments, with the second performed just before planned coronary angioplasty.

Main Results:

  • Rapid coronary artery disease progression was observed in 31.5% of patients.
  • Patients with rapid progression had significantly higher baseline plasma endothelin levels compared to those without progression (5.7 vs. 3.9 pg/mL, P<0.001).
  • Elevated endothelin was an independent predictor of disease progression, with levels above 4.26 pg/mL associated with a sixfold increased risk.

Conclusions:

  • Plasma endothelin levels are elevated in patients experiencing coronary artery disease progression.
  • Increased endothelin may serve as a valuable risk marker for rapid stenosis progression.
  • Endothelin might play a direct role in the pathogenesis of coronary artery disease progression.

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme (ECE). Of...

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...
Acute Coronary Syndrome I: Introduction01:30

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...
Angina I: Introduction01:30

Angina I: Introduction

Definition and Symptoms: Angina (angina pectoris) is chest pain or discomfort caused by myocardial ischemia, which occurs when the heart muscle receives insufficient oxygen-rich blood. It typically manifests as pressing, squeezing, or crushing sensations in the chest and may radiate to the shoulders, arms, neck, jaw, or back.Primary Cause: In a healthy state, the coronary arteries can dilate (widen) to increase blood flow and meet the increased oxygen demand during physical activity or...
Angina II: Classification01:27

Angina II: Classification

Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...

Angina III: Clinical Manifestations and Assessment

Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...
