Which lesion in rheumatic disease is most harmful to the body?

Rheumatic carditis is the most harmful manifestation of rheumatic disease to the body.

Rheumatic disease is a systemic connective tissue disorder primarily caused by streptococcal infection, which can affect the joints, heart, skin, nervous and mental systems, blood vessels, lungs, kidneys, and other organs. Myocarditis is a common complication following recurrent episodes of rheumatic disease, characterized by damage to the heart valves.

In the early stages, there are usually no obvious clinical symptoms. However, as the condition progresses, symptoms such as palpitations, shortness of breath, chest discomfort, general fatigue, tachycardia, dyspnea, and orthopnea may develop. Severe cases may lead to pulmonary edema and heart failure, causing the greatest harm to the body.

If rheumatic heart disease is caused by rheumatic disease, electrocardiogram (ECG) and echocardiography should be performed for evaluation. After a definitive diagnosis, treatment includes antibiotics to combat streptococcal infection, along with corticosteroids and immunosuppressive agents.

Patients with rheumatic disease should maintain a balanced diet emphasizing proper nutrition, consuming adequate protein, fresh fruits, and vegetables, which can aid in recovery.
