What is rheumatic heart disease?
Rheumatic heart disease (RHD) is a disorder of the heart in which irreversible valve damage and heart failure, along with, organ damage is seen following a streptococcal throat infection. Acute rheumatic fever (ARF) is the precursor of this disease.
Here is the complete detail about heart disease treatment.

What are its main signs and symptoms?
Sometimes RHD can occur without any symptoms and symptoms, if present, may include:
- When damaged heart valves are infected, fever is an associated symptom.
- Swelling (oedema).
- Problems with breathing in lying down position (orthopnoea) and/or breathlessness on exertion.
- Pain in the chest or heart palpitations.
- Arousal from sleep feeling the need to sit or stand up (paroxysmal nocturnal dyspnoea).
- Fainting (syncope).
- Heart murmur.
- Stroke.

What are the main causes?
The main cause of RHD is group A streptococci infection, which causes an abnormal autoimmune response in a host who is genetically susceptible. This exaggerated reaction leads to inflammation across multiple tissues in the body.

How is it diagnosed and treated?
The physician will take a detailed history of the symptoms and medical history (evidence of past ARF or streptococcal infection) along with a thorough physical examination. Sometimes, a heart murmur is encountered during this examination, which may suggest RHD. However, in some patients with RHD, a heart murmur may not be heard. The physician might also suggest the following tests:
- Chest X-ray – For checking heart enlargement or presence of fluid in the lungs.
- Electrocardiogram (ECG) – For checking heart chambers enlargement or abnormality in the heart rhythm (arrhythmia).
- Echocardiogram – For checking the heart valves (for damage, infection).
Management of RHD varies as per the severity of the disease and includes:
- In cases of heart failure, hospital admission is necessary for treatment.
- For infections, generally seen in the heart valves, antibiotics (mainly penicillin) are also prescribed.
- For prevention of stroke or when thinning blood is required for replacement of valves, blood-thinning medicines are prescribed.
- To open up stuck valves, balloon surgery is required where a balloon is inserted through a vein.
- For repairing or replacing damaged heart valves, heart valve surgery may be required.
