Endocarditis II: Clinical Features of Infective Endocarditis01:25

Endocarditis II: Clinical Features of Infective Endocarditis

434
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Endocarditis I: Introduction01:25

Endocarditis I: Introduction

402
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...

A Thrombotic Stroke Model Based On Transient Cerebral Hypoxia-ischemia

15.4K
Thromboembolic stroke models are vital tools for optimizing the recanalization therapy. Here we report a murine thrombotic stroke model based on transient cerebral hypoxic-ischemic (tHI) insult, which triggers thrombosis and infarction, and responds favorably to tissue plasminogen activator (tPA)-mediated fibrinolysis in a therapeutic window similar to those in stroke patients.

This video demonstrates the procedure of replicating a thrombotic stroke in a mouse model by blocking the right common carotid artery and exposing the mouse to a low-oxygen environment. This process reduces blood and oxygen flow to the brain, causing blood clot formation and brain...

Endocarditis III: Medical Management

217
Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

Endocarditis IV: Nursing Management01:29

Endocarditis IV: Nursing Management

331
Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Area of Science:

  • Cardiology
  • Rheumatology
  • Infectious Diseases

Background:

  • Rheumatoid arthritis (RA) is a chronic autoimmune disease.
  • Comorbidities like chronic kidney disease (CKD) and heart failure (HF) are common in RA patients.
  • Infective endocarditis (IE) is a serious complication that can present with vegetations on heart valves.

Observation:

  • An 83-year-old female with RA presented with UTI, CKD exacerbation, and decompensated HF.
  • Transesophageal echocardiography (TEE) revealed mitral valve vegetations, initially suggesting IE.
  • Despite empirical antibiotic treatment, vegetations persisted, prompting further investigation.

Findings:

  • Clinical and laboratory findings excluded an infectious process.
  • Diagnosis of nonbacterial thrombotic endocarditis (NBTE) was established.
  • NBTE vegetations resolved completely after two months of anticoagulant therapy.

Implications:

  • NBTE should be considered in the differential diagnosis of cardiac vegetations, especially in patients with autoimmune conditions.
  • Early diagnosis and initiation of anticoagulant therapy are crucial for managing NBTE.
  • This case highlights the importance of a comprehensive diagnostic approach to cardiac vegetations.
