A case of plateau heart disease misdiagnosed as chronic pulmonary heart disease.

This paper reports a case of plateau heart disease in Qinghai-Tibetan plateau who had recurrent symptoms of chest tightness and shortness of breath for 6 years but was misdiagnosed as chronic pulmonary heart disease. Plateau heart disease was diagnosed by thoracic computed tomography, pulmonary arteriography, pulmonary function tests and examination of medical history. Through the detailed analysis and differential diagnosis of this case, the aim is to distinguish between high-altitude heart disease and high-altitude chronic pulmonary heart disease, with the hope of achieving new breakthroughs in the diagnosis and treatment of this condition in the future.
