Insights

Complement system activation, specifically elevated C1rC1sC1inh levels, is linked to coronary atherosclerosis. This finding suggests C1rC1sC1inh may serve as a valuable biomarker for identifying coronary artery disease.

Area of Science:

  • Immunology
  • Cardiovascular Medicine
  • Biomarker Discovery

Background:

  • The complement system plays a role in coronary atherosclerosis and cardiovascular diseases.
  • Understanding complement activation in stable atherosclerotic coronary heart disease (ACHD) is crucial.

Purpose of the Study:

  • To investigate the extent and clinical significance of complement system activation in patients with stable ACHD.
  • To determine if complement activation products are biomarkers for coronary artery disease.

Main Methods:

  • Seventy-six patients with stable angina pectoris were assessed via coronary angiography.
  • Plasma levels of complement activation products (C1rC1sC1inh, C3bBbP, SC5b-9) were measured before angiography.
  • Patients were categorized into percutaneous coronary intervention (PCI), no PCI (significant stenosis), and no coronary disease (NC) groups, with 115 healthy controls (HC).

Main Results:

  • Patients with angiographically proven ACHD (PCI and NOPCI groups) exhibited significantly higher baseline C1rC1sC1inh levels than NC and HC groups (p<0.0001).
  • Elevated C1rC1sC1inh levels were identified as an independent biomarker for coronary heart disease (p<0.026, OR: 65.3).

Conclusions:

  • Activation of the classical complement pathway is evident in patients with coronary atherosclerosis.
  • Elevated C1rC1sC1inh levels show potential as a useful biomarker for coronary artery disease.

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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

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...

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

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...

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
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...
