Rheumatic heart disease (RHD) is a serious heart condition caused by long-term damage to the heart valves following rheumatic fever, an inflammatory disease that can develop after untreated throat infections caused by streptococcal bacteria.
Although it is preventable, rheumatic heart disease remains a major cause of heart problems in many parts of the world, particularly among children and young adults.
What Is Rheumatic Heart Disease?
Rheumatic heart disease occurs when the immune response triggered by a streptococcal throat infection damages the heart valves. Over time, repeated inflammation causes scarring and deformity of the valves.
The most commonly affected valve is the mitral valve, although other valves may also be involved.
Damaged heart valves interfere with normal blood flow through the heart.
How Rheumatic Heart Disease Develops
The condition usually develops in stages:
- Strep throat infection occurs
- The body’s immune system reacts to the infection
- Rheumatic fever develops in some individuals
- Inflammation affects the heart, joints, skin, and brain
- Heart valves become scarred and damaged
- Long-term valve disease develops
Without treatment, repeated infections can worsen valve damage.
Symptoms of Rheumatic Heart Disease
Symptoms may take years to appear after the initial infection.
Common symptoms include:
- Shortness of breath
- Fatigue
- Chest discomfort
- Heart palpitations
- Swelling in legs and feet
- Dizziness
- Fainting
Symptoms may worsen during physical activity.
Signs Related to Heart Valve Damage
Damage to the valves may cause:
- Heart murmurs
- Irregular heartbeat
- Fluid buildup in lungs
- Reduced exercise tolerance
Severe valve damage can eventually lead to heart failure.
Who Is at Higher Risk?
Rheumatic heart disease is more common in:
- Children and adolescents
- Individuals with untreated strep throat
- People living in crowded environments
- Populations with limited access to healthcare
- Individuals with repeated throat infections
Possible Complications
If untreated, rheumatic heart disease may lead to serious complications:
- Heart valve stenosis (narrowing)
- Heart valve regurgitation (leakage)
- Heart failure
- Stroke
- Infective endocarditis
- Irregular heart rhythms (arrhythmias)
These complications may require surgery.
Diagnosis
Doctors may use several tests to diagnose the condition:
- Physical examination
- Echocardiogram (heart ultrasound)
- Electrocardiogram (ECG)
- Chest X-ray
- Blood tests for infection markers
Early diagnosis helps prevent further damage.
Treatment
Treatment focuses on controlling infection and managing heart valve damage.
Possible treatments include:
- Antibiotics to treat or prevent strep infections
- Anti-inflammatory medications
- Medications to control heart symptoms
- Valve repair or replacement surgery in severe cases
Long-term antibiotic therapy may be recommended to prevent recurrence.
Prevention
Preventing rheumatic heart disease mainly involves treating throat infections early.
Preventive measures include:
- Prompt treatment of strep throat
- Completing prescribed antibiotics
- Improving hygiene
- Regular medical checkups
- Long-term antibiotic prophylaxis in high-risk patients
When to Seek Medical Care
Medical attention should be sought if symptoms include:
- Persistent sore throat with fever
- Joint pain and swelling
- Chest pain
- Shortness of breath
- Heart palpitations
Early treatment of throat infections can prevent rheumatic fever and heart damage.
Conclusion
Rheumatic heart disease is a preventable but potentially serious condition caused by untreated streptococcal throat infections. Over time, inflammation can damage heart valves and lead to lifelong cardiac complications.
Early diagnosis, proper treatment of infections, and preventive care play a crucial role in reducing the risk of this disease and protecting long-term heart health.
