Insights

Plasma hydrogen sulfide (H2S) is a potential biomarker for predicting coronary artery lesions in children with Kawasaki disease (KD). Lower H2S levels in acute KD patients may indicate a higher risk of coronary artery damage.

Area of Science:

  • Biochemistry
  • Pediatrics
  • Cardiology

Background:

  • Kawasaki disease (KD) is a critical pediatric illness.
  • Coronary artery lesions (CAL) are a major complication of KD.
  • Identifying biomarkers for CAL prediction in KD is crucial.

Purpose of the Study:

  • To investigate plasma hydrogen sulfide (H2S) as a predictive biomarker for CAL in children with KD.
  • To assess the correlation between H2S levels and the presence of CAL in acute KD.

Main Methods:

  • Prospective study involving 50 KD patients and 27 healthy controls.
  • Plasma H2S levels were measured during the acute phase of KD using a sensitive electrode method.
  • Receiver operating characteristic (ROC) curve analysis was employed to evaluate predictive performance.

Main Results:

  • Plasma H2S levels were significantly lower in acute KD patients compared to controls.
  • KD patients with CAL exhibited lower plasma H2S levels than those without CAL.
  • A plasma H2S cut-off of 31.2 µmol/L showed 81% sensitivity and 62.5% specificity for predicting coronary injuries.

Conclusions:

  • Plasma H2S is a potentially valuable biomarker for predicting coronary artery lesions in children with Kawasaki disease.
  • Acute-phase plasma H2S levels can aid in identifying KD patients at risk for CAL.

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...

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

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...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

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...
