Psychoneuroimmunology: Cardiovascular Disease01:27

Psychoneuroimmunology: Cardiovascular Disease

391
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...

Assessment of the Cardiovascular System I: Subjective Data

753
A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...

Coronary Artery Disease I: Introduction

878
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...

Coronary Artery Disease IV: Preventive Measures

589
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...

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

538
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 I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Summary

Food insecurity is linked to poorer cardiovascular health (CVH) in Korean adults, specifically increasing risks for smoking and high blood pressure. Addressing food insecurity may improve overall cardiovascular health outcomes in the region.

Area of Science:

  • Public Health
  • Nutrition Science
  • Cardiovascular Epidemiology

Background:

  • The relationship between food insecurity and cardiovascular health (CVH) among Korean adults is not well-established.
  • Understanding this association is crucial for developing targeted public health interventions.

Purpose of the Study:

  • To investigate the association between food insecurity and cardiovascular health (CVH) in a representative sample of Korean adults.
  • To identify specific cardiovascular health components affected by food insecurity.

Main Methods:

  • Utilized data from 14,034 Korean adults (aged ≥19) from the 2019-2021 Korea National Health and Nutrition Examination Survey.
  • Defined CVH using the American Heart Association's Life's Simple 7 framework.
  • Employed multivariate logistic regression to analyze the association between food insecurity status and poor CVH.

Main Results:

  • 4.0% of participants reported food insecurity, while 15.3% had poor CVH.
  • Food insecurity was significantly associated with a 1.32-fold increased odds of poor CVH (95% CI: 1.06-1.64).
  • Food insecurity correlated with higher odds of current smoking and elevated blood pressure.

Conclusions:

  • Food insecurity is a significant risk factor for poor cardiovascular health in Korean adults.
  • Interventions aimed at reducing food insecurity could potentially mitigate cardiovascular disease risk factors, including smoking and hypertension.
  • Further research and public health strategies are needed to address food insecurity for improved population cardiovascular health in Korea.
