Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

434
Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Cholesterol: Significance and Regulation

1.2K
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

362
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Area of Science:

  • Genetics
  • Pediatrics
  • Cardiology

Background:

  • Familial hypercholesterolemia (FH) is a common genetic disorder affecting approximately 1 in 300 individuals.
  • Cardiovascular disease, the primary complication of FH, often manifests in adulthood for heterozygous cases.
  • Early intervention in childhood can prevent the onset of cardiovascular complications.

Purpose of the Study:

  • To review the importance and application of genetic testing for diagnosing FH in children.
  • To discuss the latest findings on universal screening incorporating genetic testing for pediatric FH.
  • To highlight the significance of developing proactive pediatric FH management strategies.

Main Methods:

  • Review of existing research on genetic testing for pediatric FH.
  • Analysis of the utility of genetic testing in clinical diagnosis.
  • Exploration of universal screening approaches for FH in children.

Main Results:

  • Clinical diagnosis of FH in children is challenging due to the infrequent manifestation of physical indicators.
  • Genetic testing for FH is now covered by national health insurance in Japan since 2022, making it accessible for children.
  • The paper synthesizes research on genetic testing's role in early FH detection and management.

Conclusions:

  • Genetic testing is vital for the early and accurate diagnosis of FH in children, especially when clinical signs are absent.
  • Implementing universal screening with genetic testing can significantly improve pediatric FH management.
  • Proactive management of childhood FH is expected to reduce future cardiovascular complications.
