Pulmonary hypertension causes progressive right ventricular dysfunction and severe respiratory symptoms (e.g., dyspnea, hypoxemia, poor exercise tolerance, etc.). The association of myocardium iron deposition and its relationship with pulmonary hypertension has not been investigated. Pulmonary hypertension is a prevalent complication among patients with hematologic diseases, especially those with a hemolytic component to the anemia. Because many of these patients are treated with blood transfusion and consequently develop iron accumulation in the heart, the investigation of the association of myocardial hemosiderosis and pulmonary hypertension is warranted.
