Question 1

How does primary prevention help reduce the risk of rheumatic heart disease?

Accepted Answer

Primary prevention focuses on promptly treating group A streptococcal pharyngitis with antibiotics, particularly intramuscular benzathine penicillin G, to prevent acute rheumatic fever and subsequent rheumatic heart disease. Early diagnosis and treatment of streptococcal infections are critical to stopping disease progression before it damages the heart.

Question 2

What medications are used to treat acute rheumatic fever?

Accepted Answer

Acute rheumatic fever treatment focuses on suppressing inflammation to minimize cardiac and joint damage. The primary medications include salicylates, NSAIDs, and corticosteroids. These anti-inflammatory agents work to reduce the inflammatory response and protect the heart from further damage during the acute phase of illness.

Question 3

Why is secondary prophylaxis important in rheumatic heart disease management?

Accepted Answer

Secondary prophylaxis, typically involving penicillin injections every 3 to 4 weeks, effectively prevents progression of rheumatic heart disease and recurrent episodes of acute rheumatic fever. This long-term preventive strategy stops group A streptococcal reinfections, which could trigger additional inflammatory episodes and further cardiac damage.

Question 4

When is percutaneous mitral balloon valvuloplasty recommended for rheumatic heart disease?

Accepted Answer

Percutaneous mitral balloon valvuloplasty is the first-line interventional therapy for rheumatic mitral stenosis when the patient has no regurgitation, arrhythmias, or left atrial thrombus. This minimally invasive procedure restores valve function without requiring surgery, making it the preferred initial approach for suitable candidates.

Question 5

What heart failure medications are recommended for rheumatic heart disease patients?

Accepted Answer

Patients experiencing heart failure from valve disease receive medical therapy including ACE inhibitors, diuretics, and beta-blockers as tolerated. These medications help manage symptoms, reduce cardiac workload, and improve heart function in patients with rheumatic valve disease. Proper medication adherence is essential for optimal outcomes.

Question 6

What are the surgical options when severe valvular disease develops?

Accepted Answer

Severe rheumatic valvular disease may require surgical intervention through valve repair or replacement. Valve repair is preferred when valve function can be restored. If repair is not feasible, mechanical or bioprosthetic valves are used, with mechanical valves requiring lifelong anticoagulation therapy.

Question 7

How do regular monitoring and patient education support long-term rheumatic heart disease management?

Accepted Answer

Regular follow-ups with healthcare providers assess heart function and detect complications early. Patient education emphasizing medication adherence, symptom recognition, and lifestyle modifications including a low-sodium diet and moderate exercise are vital. Combined with consistent monitoring, these strategies help prevent disease progression and improve outcomes.
