Pericarditis II: Clinical Features and Diagnostic Tests

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...

Myocarditis II: Clinical Features and Diagnostic Tests

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...

Rheumatic Heart Disease I: Introduction

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...

Pericarditis I: Introduction

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...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis II: Clinical Features of Infective Endocarditis

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...

Diphtheria

Diphtheria

Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...

Summary

This case report details a woman experiencing chest pain due to acute pericarditis, a rare cardiac complication linked to a recent dengue fever infection. Prompt treatment led to good clinical and ECG outcomes.

Area of Science:

Cardiology
Infectious Diseases
Epidemiology

Background:

Dengue fever is a mosquito-borne viral illness with diverse clinical manifestations.
Cardiac complications, though rare, can occur following dengue fever infection.
Acute pericarditis is an inflammation of the pericardium, often presenting with chest pain and ECG changes.

Observation:

A 63-year-old woman presented with acute chest pain and asthenia.
Electrocardiogram (ECG) showed widespread T wave depression.
Standard cardiac investigations including echocardiography, cardiac MRI, and coronary angiography were unremarkable, apart from positive dengue fever serologies.

Findings:

The patient had a recent history of dengue fever.
The clinical presentation and ECG findings were characteristic of acute pericarditis.

A Murine Model of Dengue Virus-induced Acute Viral Encephalitis-like Disease

Published on: April 28, 2019

The pericarditis was attributed to the recent dengue fever infection.

Implications:

This case highlights acute pericarditis as a potential, albeit uncommon, cardiac complication of dengue fever.
The typical ECG presentation in this case underscores the importance of considering dengue etiology in endemic areas.
Early recognition and management of dengue-associated pericarditis can lead to favorable patient outcomes.
