Children can suffer from various types of heart diseases, much like adults. These diseases can affect both children and adolescents, with symptoms that may appear at birth. Some symptoms are temporary, while others can worsen due to infections and other factors. There are several types of heart diseases that commonly affect children. Many of these can be treated, allowing children and adolescents to lead active lives. Below are the most common types of heart diseases in children:
1. Congenital Heart Diseases
Congenital heart diseases are structural or anatomical defects in the heart that occur due to abnormal development of the fetus's heart during pregnancy. These defects can lead to abnormal blood flow and circulation within the heart. Some common congenital heart defects include:
- A hole in the heart’s septum (septal defect).
- Narrowing or blockage of the heart valves or blood vessels leading to the heart.
- Poor growth of certain heart parts.
- Conditions like "Tetralogy of Fallot," which includes a combination of four defects that affect blood flow.
2. Arteriosclerosis (Hardening of the Arteries)
Arteriosclerosis occurs when fatty deposits and cholesterol accumulate in the arteries, making them stiff and narrow. Although this condition usually takes years to develop, some studies suggest that it can begin in childhood. Risk factors include:
- Obesity.
- Diabetes (both type 1 and type 2).
- High blood pressure.
- Genetic factors.
3. Arrhythmia
Arrhythmia is a condition where the rhythm of the heart is irregular, making it pump less efficiently. Children with arrhythmia may experience symptoms such as weakness, fatigue, dizziness, and fainting.
4. Kawasaki Disease
Kawasaki disease is a rare condition that primarily affects children under the age of five. It causes inflammation of blood vessels in various parts of the body, including the coronary arteries, hands, feet, mouth, lips, and throat. Treatment typically involves medications, and children with Kawasaki disease need lifelong follow-up care to monitor their heart health.
5. Heart Murmur
A heart murmur is a sound produced when blood flows through the chambers or valves of the heart. In most cases, this condition does not cause harm. However, in some instances, a heart murmur may indicate an underlying cardiovascular problem.
6. Rheumatic Heart Disease
Rheumatic heart disease is caused by a bacterial infection, typically Group A streptococcus, which can lead to inflammation in the heart’s valves and muscle. This condition usually affects children between the ages of 5 and 15 and can be prevented with antibiotics to treat strep throat.
7. Pericarditis
Pericarditis is an inflammation of the pericardium, the thin membrane surrounding the heart. It can cause fluid buildup between the two layers of the pericardium, which interferes with the heart’s ability to pump blood effectively. Causes include surgery, bacterial, viral, or fungal infections, and autoimmune diseases such as lupus.
Symptoms of Heart Diseases in Children
- Bluish lips, tongue, or nails: This is caused by narrowing of the blood vessels, which reduces the oxygen supply to the body.
- Decreased appetite: This can occur when the digestive organs are not receiving adequate blood supply.
- Excessive sweating: Children may sweat heavily even in moderate weather or during low physical activity.
- Fainting: Fainting episodes can occur when the blood vessels do not respond properly, causing sudden drops in blood pressure due to heart problems.
- Chest heaviness: Children may feel a sense of pressure or heaviness in the chest, especially when lying down or sleeping, due to insufficient oxygen distribution to the organs.
Conclusion
It is important for parents to be aware of the symptoms of heart diseases in children and seek appropriate treatment if any of these symptoms occur. With proper medical care and treatment, children with heart conditions can lead a healthy and active life despite the challenges they may face.
