Psychoneuroimmunology: Cardiovascular Disease01:27

Psychoneuroimmunology: Cardiovascular Disease

30
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Types of Toxins

1.7K
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

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

81
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...

Blood Studies for Cardiovascular System III: Serum Lipid Profile

156
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

540
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...

Imaging Studies for Cardiovascular System III: X-Ray

180
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...

Area of Science:

  • Environmental Health
  • Cardiovascular Disease Epidemiology
  • Toxicology

Background:

  • Cardiovascular diseases (CVD) are a major global health burden, with environmental factors contributing significantly.
  • Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are persistent, man-made chemicals found globally due to widespread industrial and consumer use.
  • Ubiquitous human exposure to PFAS is a growing concern, necessitating investigation into their health impacts.

Purpose of the Study:

  • To review epidemiological evidence linking National Academies of Sciences, Engineering and Medicine identified PFAS with cardiovascular disease risk factors.
  • To explore potential associations between PFAS exposure and vascular disease, including atherosclerosis.
  • To synthesize current understanding and identify research gaps regarding PFAS and cardiovascular health.

Main Methods:

  • Systematic review of epidemiological studies investigating PFAS exposure and cardiovascular risk factors.
  • Analysis of data on associations between specific PFAS and conditions such as dyslipidemia, obesity, hypertension, and hyperuricemia.
  • Examination of evidence for PFAS links to vascular disease and atherosclerosis.

Main Results:

  • Compelling evidence supports an association between PFAS exposure and dyslipidemia.
  • Observational data indicate links between PFAS and other cardiovascular risk factors, including overweight/obesity, glucose intolerance, hypertension, and hyperuricemia.
  • Potential connections between PFAS and vascular disease and atherosclerosis are suggested by existing research.

Conclusions:

  • PFAS exposure is associated with multiple cardiovascular disease risk factors, extending beyond dyslipidemia.
  • While observational data are supportive, further research is required to establish causality and elucidate mechanisms.
  • Understanding the full impact of PFAS on cardiovascular health is crucial for public health and regulatory action.
