Introduction
The left atrium usually refers to the left upper chamber of the heart. Normally, the size of the left atrium is less than 35 mm. A measurement of 38 mm indicates a slightly enlarged left atrium. If there are no obvious symptoms, treatment may not be necessary. However, if discomfort or symptoms occur, medical intervention is required. Nevertheless, it is important to always take this condition seriously and cooperate with your doctor for appropriate evaluation and treatment.
The left atrium generally refers to the left upper chamber of the heart. Under normal circumstances, the size of the left atrium should be less than 35 mm. A measurement of 38 mm indicates a slight enlargement. If there are no obvious symptoms, treatment may not be necessary; however, if physical discomfort occurs, medical intervention is required. Detailed analysis is as follows:
1. No treatment needed
The primary function of the left atrium is to receive blood from the pulmonary veins and pump it into the left ventricle, thereby completing normal blood circulation. The normal diameter of the left atrium is less than 35 mm. At 38 mm, the left atrium is slightly enlarged and falls outside the normal range. If there are no significant symptoms associated with this mild enlargement, treatment is typically unnecessary. However, individuals should avoid cold exposure and excessive fatigue, and undergo regular follow-up examinations at a qualified hospital, including echocardiography (cardiac ultrasound) and Holter monitoring (dynamic electrocardiogram).
2. Treatment required
Left atrial enlargement may lead to hemodynamic disturbances. Increased venous return can cause volume overload, resulting in left atrial dilation. Common underlying causes include hyperthyroidism and hypertension. Left atrial enlargement can also result from increased afterload, primarily due to conditions such as mitral valve stenosis or mitral valve regurgitation. In severe cases, this may progress to heart failure. Therefore, if patients experience symptoms such as syncope (fainting), angina pectoris (chest pain), or left ventricular dysfunction, they should seek timely evaluation and appropriate treatment at a qualified medical facility.
In summary, whether a left atrial size of 38 mm requires treatment depends on the individual's specific clinical condition. Nevertheless, regardless of symptoms, this finding should be taken seriously, and patients should cooperate with healthcare providers for proper assessment and management.
