Coronary artery aneurysms caused by Kawasaki disease can be cured, and the outcome of the treatment is related to a number of factors, such as whether it is detected in a timely manner, the age of the patient, and the severity of the infection. Kawasaki disease, also known as Kawasaki’s disease or mucocutaneous lymphadenopathy syndrome, is a disease in which blood vessels throughout the body become inflamed, and the cause of the disease is unknown. Children’s hearts may develop coronary artery aneurysms either in combination with or after recovery from Kawasaki’s disease, requiring long-term follow-up. Treatment options include conservative drug therapy and surgery. Patients with mild disease are mainly treated with medications, commonly aspirin, isosorbide nitrate and reteplase, which act as antiplatelet agents, dilate coronary arteries to alleviate the symptoms of myocardial ischemia, and thrombolytic therapy for myocardial infarction, respectively. Drug therapy can improve symptoms, delay the progress of the disease, so that the surgical cure rate increased. Serious patients are treated with surgery, and the main treatment modalities are percutaneous coronary intervention and coronary artery bypass grafting. Patients will largely reduce the risk of death after active surgical treatment, thus achieving cure of the disease. If you are diagnosed with coronary artery aneurysm, please seek medical treatment in time and choose the appropriate treatment according to the patient’s condition under the guidance of the doctor to avoid delay.
