Hyperthyroid heart disease cannot be completely cured by controlling thyroid hormone levels, reducing cardiac load and slowing down the progression of the disease. Patients with hyperthyroid heart disease often have cardiac involvement, and the heart muscle can become edematous and eventually develop heart failure. Patients can develop symptoms such as dyspnea and lower extremity edema, which can be accompanied by atrial fibrillation and other cardiac arrhythmias. Hyperthyroidism heart disease has already appeared in the heart structural changes, can not be completely cured, to slow down the progress of the disease. Patients with hyperthyroid heart disease should control the level of thyroid hormones to reduce the toxic effects of thyroid hormones on the heart, oral methimazole. Patients with heart failure should be given medications to reduce cardiac load, such as furosemide, and patients with atrial fibrillation should be given medications to control ventricular rate, such as digoxin. Patients with hyperthyroid heart disease should go to the hospital for active treatment to reduce their symptoms and prolong their survival time.
