Insights

Cytomegalovirus disease significantly worsens long-term survival after heart transplantation, increasing coronary atherosclerosis. Early cytomegalovirus infection without disease has a less severe impact on patient outcomes.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Transplantation Immunology

Background:

  • Orthotopic heart transplantation is a life-saving procedure.
  • Cytomegalovirus (CMV) infection is a common complication post-transplant.
  • The impact of CMV infection and disease on long-term heart transplant outcomes requires further elucidation.

Purpose of the Study:

  • To analyze the long-term survival of heart transplant recipients.
  • To determine the influence of cytomegalovirus infection and disease on survival.
  • To identify factors affecting post-transplant outcomes.

Main Methods:

  • Retrospective analysis of 284 heart transplant patients followed for at least five years.
  • Patients categorized into three groups: no CMV infection, CMV infection only, and CMV disease.
  • Survival analysis considered donor/recipient age and sex, rejection episodes, ischemic time, and pulmonary vascular resistance.

Main Results:

  • Recipient age was a significant factor influencing survival.
  • Patients with cytomegalovirus disease experienced significantly worse long-term survival compared to those with infection only or no infection.
  • Increased incidence of coronary atherosclerosis was identified as the cause of death in patients with prior CMV disease.

Conclusions:

  • Cytomegalovirus disease, not just infection, is a critical determinant of poor long-term survival in heart transplant recipients.
  • CMV disease is strongly associated with the development of fatal coronary atherosclerosis post-transplantation.
  • Understanding and managing CMV disease is crucial for improving long-term outcomes in heart transplant patients.

Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
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...
Coronary Artery Disease II: Pathophysiology01:26

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
