What causes right atrial pain during running, and what should be done about it?

Right atrial pain during running may be caused by excessive exercise, costochondritis, hypertrophic cardiomyopathy, or other reasons. Treatment options include general management, medication, surgery, and others. The specific analysis is as follows:

1. Excessive Exercise

Excessive physical activity during running may overload the heart, leading to myocardial ischemia and pain. Exercise should be performed according to individual capacity. If discomfort occurs, adequate rest is recommended.

2. Costochondritis

Costochondritis is an inflammation of the cartilage at the junction between the ribs and sternum. Inflammatory irritation of nerve endings causes pain. Patients may take nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids such as diclofenac sodium sustained-release tablets or prednisone tablets under medical guidance.

3. Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy is a heart condition characterized by thickened myocardium, resulting in abnormal cardiac structure and function. During exercise, increased exertion may加重 cardiac load, causing myocardial ischemia and pain. Treatments include septal myectomy or septal ablation.

In addition to the above causes, right atrial pain could also result from congenital heart disease, heart failure, pericardial tumors, or other conditions. Given the variety of possible underlying factors, this symptom should be taken seriously, and timely medical evaluation is necessary.
