Insights

Human cytomegalovirus (HCMV) infection may drive cardiovascular disease by promoting atherosclerosis. This review examines recent evidence on HCMV

Area of Science:

  • Virology
  • Cardiology
  • Immunology

Background:

  • Human cytomegalovirus (HCMV) infections are typically asymptomatic in healthy adults but can cause severe illness in immunocompromised individuals.
  • Associations between cardiovascular disease (CVD) and HCMV seropositivity are observed in older adults, yet the underlying mechanisms remain poorly understood.

Purpose of the Study:

  • To review recent evidence (last 5 years) on the mechanisms by which HCMV contributes to atherosclerosis.
  • To discuss the link between HCMV infection and cardiovascular outcomes in high-burden populations.

Main Methods:

  • Systematic review of scientific literature published within the last five years.
  • Analysis of direct and indirect mechanisms of HCMV involvement in atherogenesis.
  • Examination of epidemiological data linking HCMV to CVD in specific patient groups.

Main Results:

  • HCMV can directly and indirectly promote the development and progression of atherosclerotic plaques.
  • Evidence suggests a role for HCMV in cardiovascular complications across various immunocompromised populations.

Conclusions:

  • HCMV is implicated in the pathogenesis of atherosclerosis and cardiovascular disease.
  • Further research is warranted to elucidate HCMV's role in CVD, particularly in vulnerable populations.

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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Cardiomyopathy I: Introduction and Classification

Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

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...

Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

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...
