Case Reports in Cardiology
|November 6, 2019
Summary
Iron deficiency anemia can cause heart failure in children. In some cases, this cardiac damage may be irreversible, even after treating the anemia, highlighting the need for prompt pediatric cardiology care.
Area of Science:
- Pediatric Cardiology
- Hematology
- Cardiovascular Medicine
Background:
- Iron deficiency anemia (IDA) is linked to secondary cardiomyopathy.
- The traditional view is that anemia causes cardiac dysfunction.
- Severe or prolonged IDA may lead to irreversible myocardial damage.
Observation:
- A 4-year-old child with IDA presented with dilated cardiomyopathy and congestive heart failure.
- The child's condition worsened despite anemia correction.
- The patient required advanced heart failure management, including milrinone and heart transplantation.
Findings:
- This case suggests that myocardial injury from IDA can be irreversible in children.
- Cardiac remodeling may occur despite timely hematologic treatment.
- Pediatric heart failure can be a severe complication of IDA.
Implications:
- Clinicians must recognize the risk of irreversible cardiac damage in pediatric IDA.
- Early pediatric cardiology consultation is crucial for managing IDA-associated heart failure.
- Serial cardiac assessments are vital for timely intervention and optimizing heart failure therapy.

415
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,...

413
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...

01:25Cardiomyopathy I: Introduction and Classification
452
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...

335
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...

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...

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...
