What Are the Symptoms of Rheumatic Heart Disease?

Rheumatic heart disease (RHD) commonly presents with symptoms such as palpitations, shortness of breath, fatigue, cough with sputum production, lower-limb edema, and joint discomfort. Symptom severity varies depending on disease progression; early-stage manifestations may be atypical in some individuals. As cardiac damage worsens, symptoms gradually become more apparent—prompt medical evaluation is essential upon noticing any related discomfort.

1. Palpitations: RHD damages heart valves, often leading to arrhythmias. Patients may experience palpitations even at rest or during mild physical activity. During episodes, they may notice a markedly increased heart rate and irregular rhythm. Frequent occurrences suggest elevated cardiac workload and warrant close attention to bodily changes.

2. Shortness of breath and fatigue: Reduced cardiac pumping capacity leads to systemic hypoxia, resulting in dyspnea and fatigue. Initially, patients typically feel breathless only after exertion—for example, during labor-intensive tasks or stair climbing. As the disease progresses, dyspnea may occur even while sitting quietly at rest, accompanied by marked decline in exercise tolerance and rapid onset of exhaustion with minimal activity.

3. Cough and sputum production: Valvular abnormalities can cause pulmonary congestion, leading to recurrent cough and sputum production. Symptoms often worsen when lying flat at night. Some patients may produce frothy sputum, and coughing may intensify following upper respiratory infections—potentially leading to misdiagnosis as a common respiratory condition and subsequent neglect.

4. Lower-limb edema: Impaired cardiac function compromises systemic venous return, predisposing patients to lower-limb edema—typically beginning at the ankles and calves. Pressing the swollen area leaves a visible indentation (pitting edema). Edema tends to worsen with physical exertion and improves somewhat with rest and leg elevation. Recurrent edema indicates significant impairment of cardiac function.

5. Joint discomfort: During active rheumatic phases, patients may experience migratory pain in large joints, accompanied by redness, swelling, and tenderness. Joint symptoms often resolve spontaneously without residual deformity; however, they frequently parallel the progression of cardiac involvement. Many patients focus solely on joint pain and overlook concurrent, potentially serious cardiac damage.

In daily life, maintain adequate warmth to prevent cold exposure, take precautions against streptococcal pharyngitis, avoid excessive physical exertion, engage in appropriately paced physical activity, maintain emotional stability, and thereby reduce cardiac strain. Regular cardiac evaluations are crucial for timely detection and prevention of disease progression.
