The pulmonary arterial hypertension is a clinical condition characterized by the presence of pre-capillary pulmonary hypertension and pulmonary vascular resistance of more than 3 Wood units in the absence of other causes of re-capillary pulmonary hypertension. According to the recommendations of ESC and ERS, the diagnosis of idiopathic pulmonary arterial hypertension is based on the clinical symptomatology and results of various studies: electrocardiogram, chest radiograph, pulmonary function tests and arterial blood gases, echocardiography, pulmonary scintigraphy, computed tomography, computed tomography pulmonary angiogram, heart magnetic resonance, blood and immunological tests, abdominal ultrasound, right heart catheterization and vascular reactivity and genetic tests. The pulmonary scintigraphy is central to the diagnostic algorithm. It is necessary to be performed in patients with pulmonary hypertension in order to detect and prove the presence of chronic thromboembolic pulmonary hypertension. Pulmonary scintigraphy is more sensitive than computed-tomographic pulmonary angiography, due to which it is a screening method of choice for establishing chronic thromboembolic pulmonary hypertension.
