Abstract
Primary pulmonary hypertension is a rare and progressive disease with poor prognosis. Despite much previous studies, there is neither clear explanation in the etiology and the pathogenesis nor confirmative treatment modalities.
Its main cause of death is due to the right ventricular failure but the left ventricular function is relatively well preserved. The chest pain mimickig the angina pectoris is common and it is mostly due to the right ventricular ischemia or distension of pulmonary artery, but left ventricular ischemia or infarction is very rarely seen.
We experienced a case of primary pulmonary hyperetension with left ventricular hypertrophy that complicated to acute myocardial infarction in 14-year-old male.
