Causes & Risk Factors
Several factors can contribute to Rheumatic Heart Disease.
Rheumatic heart disease develops through a specific chain of events that begins with a common childhood infection.
Rheumatic heart disease develops through a specific chain of events that begins with a common childhood infection. Group A Streptococcus bacteria, the same germs that cause strep throat, trigger an autoimmune response in susceptible individuals. When strep throat goes untreated or receives inadequate antibiotic treatment, the immune system can mistakenly attack healthy tissues in the body, including the heart, joints, brain, and skin. This autoimmune reaction is called rheumatic fever.
During episodes of rheumatic fever, inflammation targets the heart's valves, causing them to swell and become damaged.
During episodes of rheumatic fever, inflammation targets the heart's valves, causing them to swell and become damaged. The mitral valve, which controls blood flow between the heart's left chambers, suffers damage most frequently. The aortic valve, which regulates blood leaving the heart, is the second most commonly affected. As inflammation subsides, scar tissue forms on these delicate structures, causing them to thicken, stiffen, or fuse together abnormally.
The heart valve damage from rheumatic fever is permanent and often progressive.
The heart valve damage from rheumatic fever is permanent and often progressive. Over months, years, or decades, the scarred valves may become increasingly narrow (stenosis) or leaky (regurgitation). This forces the heart to work harder to pump blood effectively, eventually leading to the symptoms and complications of rheumatic heart disease. Multiple episodes of rheumatic fever typically cause more severe heart damage, which is why preventing recurrent strep infections becomes crucial for anyone who has had rheumatic fever.
Risk Factors
- History of untreated or inadequately treated strep throat
- Previous episodes of rheumatic fever
- Living in crowded or poor housing conditions
- Limited access to healthcare and antibiotics
- Age between 5-15 years when strep infection occurs
- Family history of rheumatic fever
- Genetic predisposition to autoimmune responses
- Living in developing countries with high strep prevalence
- Malnutrition or poor general health status
- Exposure to group A streptococcal outbreaks
Diagnosis
How healthcare professionals diagnose Rheumatic Heart Disease:
- 1
Diagnosing rheumatic heart disease typically begins when a doctor hears an abnormal heart murmur during a routine examination or when a patient reports symptoms like shortness of breath or chest pain.
Diagnosing rheumatic heart disease typically begins when a doctor hears an abnormal heart murmur during a routine examination or when a patient reports symptoms like shortness of breath or chest pain. The doctor will ask detailed questions about childhood illnesses, particularly whether the patient ever had rheumatic fever, and will listen carefully to the heart with a stethoscope. Different types of murmurs provide clues about which valves are affected and how severely.

An echocardiogram serves as the gold standard test for diagnosing rheumatic heart disease.
An echocardiogram serves as the gold standard test for diagnosing rheumatic heart disease. This painless ultrasound of the heart creates detailed images of the heart valves, showing whether they're thickened, scarred, narrowed, or leaky. The test also reveals how well the heart is pumping and whether the chambers have enlarged due to valve problems. Additional tests may include an electrocardiogram (ECG) to check for irregular heart rhythms, chest X-rays to look for heart enlargement or lung congestion, and blood tests to check for signs of ongoing inflammation.

Doctors must distinguish rheumatic heart disease from other conditions that can cause similar symptoms and valve problems.
Doctors must distinguish rheumatic heart disease from other conditions that can cause similar symptoms and valve problems. These include congenital heart defects, infections of the heart valves (endocarditis), mitral valve prolapse, and age-related valve degeneration. The characteristic pattern of valve damage seen in rheumatic heart disease, combined with a history of rheumatic fever or childhood strep infections, usually makes the diagnosis clear. In some cases, cardiac catheterization may be needed to assess the severity of valve problems before surgery.
Complications
- Rheumatic heart disease can lead to several serious cardiovascular complications, with heart failure being among the most common and concerning.
- As damaged valves force the heart to work harder over time, the heart muscle may weaken and enlarge, eventually losing its ability to pump blood effectively throughout the body.
- This can result in fluid accumulation in the lungs and legs, severe fatigue, and life-threatening breathing difficulties.
- Atrial fibrillation, an irregular heart rhythm, frequently develops in patients with rheumatic heart disease, particularly those with mitral valve involvement.
- This arrhythmia significantly increases the risk of stroke because blood can pool and clot in the irregularly beating heart chambers.
- Infective endocarditis, a serious infection of the heart valves, poses another major threat since damaged valves are more susceptible to bacterial colonization.
- Pulmonary hypertension may develop when left-sided valve problems cause pressure to build up in the lungs, potentially leading to right-sided heart failure.
- Without proper treatment, severe rheumatic heart disease can be fatal, but with appropriate medical care and surgical intervention when needed, many patients can live relatively normal lives.
Prevention
- The most effective prevention of rheumatic heart disease lies in recognizing and properly treating strep throat infections, particularly in children.
- Parents should seek medical attention when a child develops a sore throat accompanied by fever, especially if the throat appears red with white patches or if the child has difficulty swallowing.
- A simple throat culture or rapid strep test can confirm the diagnosis, and a full course of antibiotics will eliminate the bacteria and prevent progression to rheumatic fever.
- For individuals who have already had rheumatic fever, preventing recurrent episodes becomes critical since each episode can cause additional heart damage.
- This requires long-term antibiotic prophylaxis, typically with monthly penicillin injections or daily oral antibiotics.
- The duration of this preventive treatment depends on factors such as the severity of heart involvement, age at last episode, and risk of strep exposure.
- Some patients may need prophylaxis for 10 years or until age 40, while others with severe heart damage may require lifelong treatment.
- Public health measures play a vital role in preventing rheumatic heart disease on a population level.
- These include improving living conditions to reduce overcrowding, ensuring access to healthcare and antibiotics, and implementing school-based programs to identify and treat strep infections promptly.
- Education about recognizing strep throat symptoms and the importance of completing antibiotic courses helps families take appropriate action when infections occur.
Treatment for rheumatic heart disease focuses on managing symptoms, preventing further damage, and addressing complications as they arise.
Treatment for rheumatic heart disease focuses on managing symptoms, preventing further damage, and addressing complications as they arise. The most crucial aspect of treatment involves preventing recurrent episodes of rheumatic fever through long-term antibiotic prophylaxis. Patients typically receive monthly injections of penicillin or daily oral antibiotics for many years, sometimes for life, to prevent strep infections that could cause additional heart damage.
Medications form the backbone of symptom management for rheumatic heart disease.
Medications form the backbone of symptom management for rheumatic heart disease. Diuretics help reduce fluid buildup and swelling, while ACE inhibitors or ARBs can ease the heart's workload and slow disease progression. Beta-blockers may be prescribed to control heart rate and reduce palpitations. For patients with atrial fibrillation, a common complication, anticoagulants like warfarin help prevent dangerous blood clots from forming.
When valve damage becomes severe and medications no longer provide adequate relief, surgical intervention may be necessary.
When valve damage becomes severe and medications no longer provide adequate relief, surgical intervention may be necessary. Valve repair procedures can sometimes restore normal valve function, particularly for mitral valve problems. When repair isn't possible, valve replacement with either mechanical or biological prostheses can dramatically improve symptoms and life expectancy. Balloon valvuloplasty, a less invasive procedure, may be an option for some patients with valve narrowing.
Lifestyle modifications play an important supporting role in treatment.
Lifestyle modifications play an important supporting role in treatment. Patients should maintain a heart-healthy diet low in sodium, engage in appropriate levels of physical activity as recommended by their cardiologist, and avoid tobacco and excessive alcohol. Regular dental care with antibiotic prophylaxis before dental procedures helps prevent infective endocarditis. Close monitoring with regular echocardiograms allows doctors to track disease progression and adjust treatment as needed.
Living With Rheumatic Heart Disease
Living successfully with rheumatic heart disease requires a partnership between patients, their families, and healthcare providers. Regular medical follow-ups are essential, typically every 6-12 months, to monitor heart function and adjust treatments as needed. Patients should learn to recognize warning signs that might indicate worsening heart failure, such as increased shortness of breath, rapid weight gain from fluid retention, or decreased exercise tolerance, and contact their healthcare provider promptly when these occur.
