What causes left atrial enlargement with mild mitral regurgitation, and what should be done about it?

Left atrial enlargement and mild mitral regurgitation may be caused by conditions such as hypertension, cardiomyopathy, or rheumatic heart disease, and can be treated with medications, surgery, or other methods. A detailed analysis is as follows:

1. Hypertension

Hypertension is a common condition. Persistently elevated blood pressure can overload the left atrium, leading to left atrial enlargement and mitral regurgitation. Under medical guidance, patients may use medications such as angiotensin-converting enzyme (ACE) inhibitors and calcium channel blockers, including captopril tablets and amlodipine besylate tablets.

2. Cardiomyopathy

Cardiomyopathy can easily cause myocardial damage and inadequate blood supply to the heart, resulting in cardiac enlargement. Under medical supervision, patients may be treated with medications such as fructose diphosphate sodium oral solution and adenosine disodium triphosphate tablets.

3. Rheumatic Heart Disease

Rheumatic heart disease is an autoimmune disorder triggered by streptococcal infection. Due to impaired cardiac function and obstructed blood flow, imaging tests may reveal left atrial enlargement and mild mitral regurgitation. Patients can be treated with percutaneous balloon mitral valvuloplasty.

In addition to the above causes, left atrial enlargement and mild mitral regurgitation may also result from congenital heart defects, myocardial infarction, or heart failure. During illness, it is important to get adequate rest and avoid excessive fatigue to prevent worsening of symptoms.
