About Rheumatic Heart Disease
Rheumatic heart disease is caused by an abnormal immune response to a bacterial infection called Streptococcus pyogenes (group A streptococcus). The bacteria can spread through respiratory droplets when a person coughs or sneezes. The disease mechanism involves the following processes:
- Inflammatory response: The body's immune system reacts to the infection by mounting an inflammatory response. In some individuals, this immune response becomes aberrant and targets the heart valves.
- Valve damage: The inflammation in the heart tissue leads to damage and scarring of the heart valves. This can result in valve dysfunction, affecting blood flow through the heart.
Non-modifiable risk factors for rheumatic heart disease are factors that cannot be changed. These include:
- Age: The risk of developing rheumatic heart disease increases with age.
- Genetic Predisposition: Having a positive family history of rheumatic heart disease or related conditions can increase the risk.
Modifiable risk factors for rheumatic heart disease are factors that can be influenced or changed. These include:
- Poor dental hygiene: Not brushing teeth after meals may increase the risk of developing rheumatic heart disease.
- Urban residence: Living in urban areas has been associated with a higher risk of rheumatic heart disease.
It's important to note that these risk factors may vary in different populations and individual circumstances. Lifestyle modifications and good oral hygiene practices are generally recommended to reduce the risk of rheumatic heart disease.
The most common early symptoms of rheumatic heart disease include:
- Chest pain or discomfort
- Shortness of breath
- Swelling of the stomach, hands, or feet
- Fatigue
- Rapid or irregular heartbeat
As rheumatic heart disease progresses or reaches higher severity, other common symptoms may occur, such as:
- Fever
- Pain in the joints, especially the knees, ankles, elbows, and wrists
- Jerky and uncontrollable body movements (chorea)
- Enlarged heart
- Fluid around the heart
- Development of nodules (painless lumps) near joints
- Ring-like rash
In addition to these symptoms, complications of rheumatic heart disease can include heart failure, stroke, pulmonary embolism, pulmonary hypertension, arrhythmias (irregular heart rhythms), and endocarditis (infection of the lining around the heart). It's important to note that some people may not experience any symptoms until they have heart problems later in life. If you are experiencing any symptoms or have concerns about rheumatic heart disease, it is important to consult with a healthcare professional for proper evaluation and guidance.
To diagnose rheumatic heart disease, doctors commonly perform the following examinations, tests, and procedures:
- Medical history: Doctors ask about past strep throat infections, history of rheumatic fever, symptoms, and family history of heart disease.
- Physical examination: Doctors check for signs of heart valve damage, such as a heart murmur, and listen to the lungs for signs of congestion.
- Chest X-ray: This helps check for an enlarged heart.
- Electrocardiogram (EKG): Measures the heart's electrical activity to look for evidence of heart valve damage.
- Blood test: Checks for atypical immune response or inflammation.
- Echocardiogram (heart ultrasound): Provides detailed images of the heart's structure and function.
To determine the stage or severity of rheumatic heart disease, additional examinations, tests, and procedures may be performed:
- Cardiac magnetic resonance imaging (MRI): Provides detailed images of the heart's structure and function using magnetic fields and radio waves.
- Stress test: Evaluates how well the heart functions during physical activity.
- Cardiac catheterization: Involves inserting a wire into an artery to measure blood flow in small blood vessels.
Remember, diagnosis and staging of rheumatic heart disease require consultation with a healthcare professional. They will determine the appropriate tests based on individual circumstances.
The goals of treatment for rheumatic heart disease are to:
- Treat the underlying condition
- Relieve symptoms
- Slow disease progression
- Improve quality of life
To achieve these treatment goals, various approaches may be recommended:
- Medications: Diuretics, blood pressure medications, anti-inflammatory drugs, anticoagulants (blood thinners), and medications to regulate heart rhythm may be prescribed based on individual needs.
- Therapeutic procedures: In severe cases, cardiac surgery may be required to repair or replace damaged heart valves. This surgical intervention aims to restore normal heart function.
- Health behavior changes: Adopting a heart-healthy lifestyle can support the management of rheumatic heart disease. This includes maintaining a balanced diet low in salt and saturated fats, engaging in regular physical activity, quitting smoking (if applicable), and managing stress levels.
It is important to consult with a healthcare professional who can provide personalized recommendations tailored to each individual's specific needs. Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
