Abstract

Insights

Salmonella Enteritidis can cause rare cases of myopericarditis, even in immunocompetent individuals. Cardiac MRI is valuable for diagnosing myocarditis and assessing ventricular function in these unusual infections.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Medical Imaging

Background:

  • Myopericarditis, inflammation of the heart muscle and pericardium, is typically caused by viral infections.
  • Infections by Salmonella species are a rare but serious cause of myopericarditis, associated with high morbidity and mortality.
  • This case highlights a rare presentation of myopericarditis in an otherwise immunocompetent patient.

Observation:

  • A 44-year-old male presented with symptoms of fever, dyspnea, and chest pain, indicative of sepsis and cardiac tamponade.
  • Pericardial fluid analysis revealed Salmonella enterica serovar Enteritidis (S. Enteritidis) infection.
  • The patient was diagnosed with type 2 diabetes mellitus upon admission.

Findings:

  • Successful treatment with antibiotics (ceftriaxone, levofloxacin, ciprofloxacin) led to full recovery.
  • Cardiac magnetic resonance (CMR) imaging suggested myocarditis, despite normal initial Troponin T levels.
  • This finding underscores the diagnostic utility of CMR in cases of suspected myopericarditis.

Implications:

  • This case emphasizes the importance of considering Salmonella species as a potential cause of myopericarditis, even in immunocompetent patients.
  • The diagnostic value of cardiac magnetic resonance imaging in evaluating myocarditis and ventricular function is highlighted.
  • Early recognition and appropriate antibiotic therapy are crucial for managing Salmonella-induced myopericarditis.

Myocarditis I: Introduction01:21

Myocarditis I: Introduction

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Pericarditis I: Introduction01:22

Pericarditis I: Introduction

Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

Pericarditis II: Clinical Features and Diagnostic Tests

Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Endocarditis I: Introduction01:25

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Pericarditis IV: Nursing Management01:25

Pericarditis IV: Nursing Management

Pericarditis, an inflammation of the pericardium, necessitates diligent nursing management to ensure effective patient care and recovery. The initial step in managing pericarditis is a comprehensive patient medical assessment.The patient reports chest pain aggravated by breathing, coughing, and swallowing, which worsens when lying supine. The pain often improves when sitting up and leaning forward. Additional symptoms may include fever, malaise, and, in severe cases, signs of heart failure.
