Heart Failure Drugs: Inhibitors of Renin-Angiotensin System01:26

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

1.3K
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers01:19

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

668
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:

Psychoneuroimmunology: Cardiovascular Disease

631
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...

Atherosclerosis III: Management01:26

Atherosclerosis III: Management

538
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...

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists

558
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

Peripheral Artery Disease III: Interprofessional Care

465
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Area of Science:

  • Biomedical Science
  • Molecular Biology
  • Immunology

Background:

  • Inflammation resolution is a tightly regulated biological process.
  • Endogenous specialized pro-resolving lipid mediators (SPMs) like lipoxins, resolvins, protectins, and maresins orchestrate this resolution.
  • Unresolved inflammation is a significant factor in the pathogenesis of cardiovascular diseases.

Purpose of the Study:

  • To elucidate the receptor-dependent actions of resolvins and related SPMs.
  • To highlight the emerging roles of SPMs in the cardiovascular system.
  • To explore the potential of stimulating resolution as a therapeutic strategy for chronic cardiovascular inflammation.

Main Methods:

  • Review of scientific literature on SPMs and their mechanisms of action.
  • Analysis of receptor-dependent signaling pathways of SPMs.
  • Discussion of the implications of SPM activity in cardiovascular health and disease.

Main Results:

  • SPMs activate specific cellular receptors to reduce pro-inflammatory mediator production.
  • SPMs decrease neutrophil recruitment and enhance macrophage-mediated clearance of dead cells.
  • SPMs facilitate the transition from inflammation resolution to tissue repair.

Conclusions:

  • Understanding SPM function is critical for addressing why cardiovascular inflammation often fails to resolve.
  • Targeting SPMs offers a potential therapeutic avenue for chronic cardiovascular inflammation.
  • Stimulating pro-resolution pathways may provide a novel treatment strategy without causing immunosuppression.
