Dissection Techniques and Histological Sampling of the Heart in Large Animal Models for Cardiovascular Diseases10:53

Dissection Techniques and Histological Sampling of the Heart in Large Animal Models for Cardiovascular Diseases

9.4K
Due to the complex anatomy, a consistently reproducible dissection and harvesting protocol for cardiac samples can be challenging to implement. This manuscript presents the key elements of some standard cardiac dissection protocols, highlighting both the gross examination approaches and the sampling sites commonly used for histopathologic examination.

Digital PCR for Quantifying Circulating MicroRNAs in Acute Myocardial Infarction and Cardiovascular Disease

8.6K
Circulating microRNAs have shown promise as biomarkers for cardiovascular diseases and acute myocardial infarctions. In this study, we describe a protocol for miRNA extraction, reverse transcription, and digital PCR for the absolute quantification of miRNAs in the serum of patients with cardiovascular...

Isolation and Excision of Murine Aorta; A Versatile Technique in the Study of Cardiovascular Disease

34.1K
Pathology of the aorta can lead to severe morbidity and mortality, therefore research of disease progression and potential therapies is warranted. Here, we present a protocol to isolate and excise the murine aorta to aid researchers in their investigation of cardiovascular disease.

Psychoneuroimmunology: Cardiovascular Disease01:27

Psychoneuroimmunology: Cardiovascular Disease

414
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...

Summary

Primary care physicians can guide patients on complementary cardiovascular therapies. While some supplements lack proven benefits, lifestyle changes like plant-based diets and exercise show promise for disease prevention and management.

Area of Science:

  • Cardiology
  • Preventive Medicine
  • Nutritional Science

Background:

  • Primary care physicians play a crucial role in advising patients on cardiovascular disease (CVD) management.
  • Growing patient interest in complementary and alternative medicine (CAM) necessitates evidence-based guidance.
  • Understanding the efficacy of CAM therapies for CVD is essential for clinical practice.

Purpose of the Study:

  • To review the evidence for various complementary and alternative therapies in cardiovascular disease.
  • To provide primary care physicians with information to guide patient decisions on CAM.

Main Methods:

  • Literature review of studies on antioxidant vitamins, N-3 fatty acids, dietary interventions, red yeast rice, garlic, hawthorn, ubiquinone (Q10), and lifestyle programs.

  • Assessment of evidence for efficacy in primary and secondary prevention of cardiovascular events, cholesterol reduction, blood pressure management, and heart failure.

    • Main Results:

    • Antioxidant vitamin supplementation has not demonstrated efficacy in reducing cardiovascular events.
    • N-3 fatty acids show potential in secondary CVD prevention, but their role in primary prevention remains unclear.
    • Vegetable-based diets, whole grains, cholestin (red yeast rice), and hawthorn/ubiquinone (Q10) show promise for cardiovascular health.
    • Garlic supplements offer minimal cholesterol-lowering effects, insufficient for clinical recommendation.
    • Integrated lifestyle programs (diet, exercise, stress reduction) may serve as alternatives to conventional treatments for motivated patients.

    Conclusions:

    • While some CAM therapies lack robust evidence, dietary changes and specific supplements like cholestin and hawthorn/Q10 show potential benefits for cardiovascular health.
    • Lifestyle interventions integrating diet, exercise, and stress reduction may offer valuable alternatives for managing cardiovascular disease.
    • Evidence-based guidance from primary care physicians is critical for navigating CAM options in cardiovascular care.
