Blood Studies for Cardiovascular System III: Serum Lipid Profile

311
Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Cholesterol: Significance and Regulation

720
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...

Lipids: Dietary Sources and Requirements

1.1K
Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...

Coronary Artery Disease IV: Preventive Measures

59
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...

Atherosclerosis III: Management

54
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

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...

Summary

School-based universal screening for childhood hypercholesterolemia is effective. This strategy successfully identified high-risk children for early cardiovascular disease, proving more feasible than prior recommendations.

Area of Science:

  • Pediatrics
  • Cardiology
  • Public Health

Background:

  • The American Academy of Pediatrics recommended universal lipid screening in children in 2011.
  • Adherence to this recommendation has been low, with only 6% of non-high-risk children screened by age 12.
  • A feasible school-based strategy for hypercholesterolemia screening in children is needed.

Purpose of the Study:

  • To investigate a feasible strategy for lipid screening of children through a school-based universal screening program.
  • To assess the effectiveness of school-based screening in identifying children with hypercholesterolemia.

Main Methods:

  • Enrolled all fourth-grade students from 30 elementary schools (2020-2021).
  • Utilized non-fasting non-high-density lipoprotein (non-HDL) cholesterol as the initial screening tool.
  • Referred students with abnormal results (non-HDL ≥145 mg/dL) for confirmatory fasting lipid studies.

Main Results:

  • Six hundred students were enrolled; 95 had abnormal non-HDL levels.
  • 92% of students with abnormal results completed confirmatory testing within three months.
  • Screening coverage reached 62%, with 97% of the abnormal group referred.
  • Body Mass Index (BMI) and family history showed poor correlation with high cholesterol levels.

Conclusions:

  • School-based universal screening is a feasible and effective method for identifying children at high risk for early cardiovascular disease.
  • Neither BMI nor family history are reliable indicators for screening dyslipidemia in children.
  • This approach enhances adherence and facilitates timely intervention for pediatric hypercholesterolemia.
