Left atrial enlargement hypodiastolic function may be caused by physiological factors such as degenerative changes, which generally do not require treatment; and due to pathologic factors such as myocarditis and hypertension, which are generally treated with medication. 1. Physiological factors: with age, myocardial degenerative changes will occur, resulting in left atrial enlargement and hypodiastolic function. This is a normal physiological change, no discomfort or other symptoms, no need to worry. 2. Pathologic factors: (1) Myocarditis: inflammation damages myocardial cells, and myocardial structure changes after repair, causing left atrial enlargement and then diastolic dysfunction. Generally, coenzyme Q and phosphocreatine can be taken to improve myocardial energy metabolism, and antiviral drugs such as ribavirin and interferon can be taken. (2) Hypertension: Long-term hypertension leads to structural changes in the heart, resulting in hypertrophy and enlargement, which will slowly lead to left atrial enlargement and hypodiastolic function. Antihypertensive drugs, such as verapamil and captopril, can be chosen according to medical advice. All of the above medications should be used under the guidance of a doctor, avoid self-medication; at the same time, there may be other reasons for the left atrial enlargement of hypodiastolic function, it is recommended to go to the hospital in a timely manner, to carry out the appropriate examination to clarify the cause of the disease, and under the guidance of the doctor to give targeted treatment or therapy.
