Introduction
In general, the normal size of the left atrium is less than 35 mm. A size of 38 mm indicates mild enlargement. If the left atrium measures 38 mm and is accompanied by other symptoms, treatment may be necessary. In daily life, it is advisable to maintain a diet low in salt and fat and high in fiber, avoid excessive intake of salt and fat, engage in moderate exercise, maintain emotional stability, quit smoking, and limit alcohol consumption.
Under normal circumstances, the left atrium size is approximately 30–40 mm in males and 27–38 mm in females. If the left atrium reaches 38 mm and is accompanied by other discomfort symptoms, treatment may be required. However, if there are no symptoms such as chest pain or shortness of breath, treatment is usually unnecessary.
A normal left atrium size is less than 35 mm. A measurement of 38 mm indicates mild enlargement, which is typically caused by conditions such as hypertension, heart valve disease, or congenital heart defects. This enlargement may lead to noticeable symptoms such as palpitations, chest tightness, and shortness of breath, or may impair normal heart function, necessitating treatment to prevent further progression. Patients with more severe conditions might require surgical interventions such as valve replacement or valve repair to alleviate cardiac symptoms. If no other significant symptoms are present, treatment is generally not needed.
In daily life, it is recommended to maintain a diet low in salt and fat and high in fiber, avoid excessive intake of salt and fat, engage in moderate physical activity, maintain emotional stability, quit smoking, and limit alcohol consumption.
