Summary
We describe a rare case of complete heart block in an elderly woman with microscopic polyangiitis (MPA). This finding highlights MPA as a potential cause of heart block, requiring further investigation.
Area of Science:
- Cardiology
- Rheumatology
- Pathology
Background:
- Third-degree complete heart block has various causes, including idiopathic, pathological, and iatrogenic.
- Microscopic polyangiitis (MPA) is a rare autoimmune vasculitis that can affect multiple organs.
Observation:
- An elderly woman presented with symptoms of dyspnea on exertion and dizziness.
- Diagnostic workup revealed third-degree complete heart block.
Findings:
- The patient was diagnosed with microscopic polyangiitis (MPA).
- A rare association between MPA and complete heart block was identified.
Implications:
- This case suggests MPA should be considered in the differential diagnosis of heart block, especially in elderly patients.
- Further research is warranted to elucidate the mechanisms linking MPA and cardiac conduction abnormalities.

317
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,...

261
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...

01:18Dysrhythmias IV: Characteristics of Bradyarrhythmias
372
Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

01:25Endocarditis II: Clinical Features of Infective Endocarditis
261
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...

01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
135
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

01:23Rheumatic Heart Disease I: Introduction
314
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...
