Insights

Systemic lupus erythematosus (SLE) can affect the heart, causing conditions like pericarditis and myocarditis. This review details key pathological findings in lupus-related cardiac diseases for pathologists.

Area of Science:

  • Cardiovascular Pathology
  • Autoimmune Diseases
  • Rheumatology

Background:

  • Systemic lupus erythematosus (SLE) is a chronic autoimmune disease impacting multiple organ systems.
  • Cardiac involvement is frequent in SLE, affecting the pericardium, myocardium, endocardium, and coronary arteries.
  • Histopathological findings in lupus carditis can be nonspecific, necessitating awareness of specific diagnostic clues.

Purpose of the Study:

  • To review and describe the key pathological features of cardiac complications in systemic lupus erythematosus.
  • To highlight important histopathological findings relevant for accurate diagnosis of lupus-related cardiac disease.
  • To provide a resource for pathologists encountering cardiac manifestations of SLE.

Main Methods:

  • Literature review of pathological findings in systemic lupus erythematosus affecting the heart.
  • Compilation of characteristic histopathological descriptions for lupus carditis entities.
  • Focus on differentiating features and diagnostic considerations.

Main Results:

  • Cardiac manifestations of SLE include pericarditis, myocarditis, endocarditis, and coronary artery disease.
  • Specific pathological findings, though sometimes subtle, are crucial for diagnosing SLE-related cardiac pathology.
  • Understanding these features aids in differentiating lupus carditis from other cardiac conditions.

Conclusions:

  • Accurate pathological identification of cardiac involvement in SLE is essential for patient management.
  • Pathologists play a critical role in diagnosing lupus carditis through recognition of specific histopathological patterns.
  • This review serves to enhance diagnostic capabilities for cardiac manifestations of systemic lupus erythematosus.

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...

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

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...

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...
Cardiomyopathy II: Dilated Cardiomyopathy01:30

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

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...
