Abdominal cavity ultrasound is employed to rule out liver cirrhosis and/or portal hypertension. The utilization of contrast agents and color Dopplerography enhances diagnostic precision, enabling the differentiation of passive portal hypertension caused by right ventricular heart failure or the presence of a transhepatic venous gradient in liver cirrhosis. Objective evaluation of the functional capacity of patients with pulmonary hypertension (PH) is essential for assessing the severity of PH and monitoring the clinical condition dynamics during therapy.
