Rheumatic heart disease itself does not cause generalized pain, but during the acute phase of rheumatic fever, generalized joint pain or fever-induced muscle soreness can occur due to the disease. Rheumatic heart disease arises when rheumatic fever affects the heart valves, leading to conditions such as stenosis and insufficiency. This typically affects the mitral and aortic valves but can also involve the tricuspid and pulmonary valves. Clinical symptoms of rheumatic heart disease primarily include heart dysfunction, chronic heart failure, or acute heart failure episodes, and can also present with arrhythmias, predominantly atrial fibrillation, which can lead to an enlargement of the atria and the formation of mural thrombi, resulting in thromboembolic complications.
