Abstract Objective To analyze the clinical characteristics of patients with isolated post-capillary pulmonary hypertension (IPC-PH) and combined post- and pre-capillary pulmonary hypertension (CPC-PH), and to provide references for the clinical management of post-capillary pulmonary hypertension. Methods A total of 163 patients
diagnosed with post-capillary pulmonary hypertension by Swan-Ganz floating catheter were selected, and divided into IPC-PH and CPC-PH groups according to their hemodynamic characteristics. General data, and examination results of echocardiography and Swan-Ganz floating catheter were collected and compared. Results The serum uric acid, pulmonary artery systolic and diastolic blood pressure, and mean pulmonary artery pressure in the CPC-PH group are significantly higher than those in the IPC-PH group, while the body weight, triglyceride, aortic root diameter, cardiac output, stroke volume and cardiac index in the CPC-PH group are significantly lower than those in the IPC-PH group (P <0. 05). Conclusion CPC-PH can be distinguished from IPC-PH by blood uric acid, pulmonary artery systolic and diastolic blood pressure, mean pulmonary artery pressure, cardiac output, stroke volume, cardiac index, etc.
