Insights

Cardiovascular disease, a leading cause of death, involves heart and blood vessel conditions. Reduced endothelial progenitor cells may drive disease progression and increase risks in rheumatoid arthritis patients.

Area of Science:

  • Cardiovascular science and regenerative medicine.

Background:

  • Cardiovascular disease (CVD) is a primary cause of death globally, particularly in Western countries.
  • Atherosclerosis, a key feature of CVD, is linked to defective vascular repair and reduced circulating endothelial progenitor cells.
  • Rheumatoid arthritis (RA) patients exhibit a higher incidence of CVD, including stroke and myocardial infarction.

Purpose of the Study:

  • To review the evidence linking endothelial progenitor cells (EPCs) to cardiovascular disease development.
  • To explore the potential reasons for increased CVD risk in rheumatoid arthritis patients concerning EPC function.

Main Methods:

  • Literature review of current evidence on EPCs and cardiovascular disease.
  • Analysis of studies investigating the role of EPCs in atherosclerosis and vascular repair.
  • Examination of research on RA and its association with cardiovascular risk factors and EPCs.

Main Results:

  • Defective vascular repair, potentially due to reduced EPCs, contributes to atherosclerosis.
  • Lower levels of circulating EPCs are observed in individuals with cardiovascular disease.
  • RA patients show a heightened risk of cardiovascular events, possibly related to altered EPC function.

Conclusions:

  • Endothelial progenitor cells play a critical role in vascular health and cardiovascular disease pathogenesis.
  • Dysfunction or reduction in EPCs is a significant factor in the development and progression of cardiovascular disease.
  • Further research is warranted to understand the specific mechanisms linking rheumatoid arthritis, endothelial progenitor cells, and increased cardiovascular risk.

Rheumatic Heart Disease I: Introduction01:23

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Psychoneuroimmunology: Cardiovascular Disease

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...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
Inflammatory Response I: Vascular and Cellular01:30

Inflammatory Response I: Vascular and Cellular

The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...
Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
