What causes right atrial hypertrophy?

Right atrial hypertrophy is usually caused by long-term overload and increased pressure. This condition can be triggered by various diseases, such as pulmonary heart disease, valvular heart disease (e.g., tricuspid stenosis or insufficiency), and atrial septal defects. When pulmonary artery pressure rises or the right ventricle experiences increased workload, the right atrium must handle greater pressure from blood returning to the heart, which can eventually lead to right atrial hypertrophy. Additionally, congenital heart abnormalities, hypertensive heart disease, coronary artery disease, and other factors may also contribute to right atrial hypertrophy. Symptoms of right atrial hypertrophy may include shortness of breath, leg swelling, palpitations, and other signs indicating that the patient's cardiac function may be compromised. Treatment for right atrial hypertrophy should be based on the specific underlying cause and may involve corresponding interventions such as medication or surgical treatment. At the same time, patients should also maintain healthy lifestyle habits, avoid excessive physical strain and emotional fluctuations, and reduce the burden on the heart.
