Abstract:
Objective To investigate the incidence and the relation between pulmonary hypertension (PH) and cardiac output in hemodialysis (HD) patients with PH. Methods The incidence of PH was estimated with Doppler echocardiography in 78 patients receiving HD. Left ventricular ejection fraction, cardiac volume, cardiac output and cardiac index were compared between patients with or without PH. Results PH was found in 20 patients (25.64%), among them15 had mild PH, 4 had moderate PH and 1 had severe PH. There was no statistical difference of ejection fraction, cardiac volume, cardiac output and cardiac index between the two groups. PH was not related to cardiac output. Conclusion HD can lead to PH, but cardiac output can not result in PH. Further investigations about the effect of elevated cardiac output induced by internal arteriovenous fistula and other factors on PH are needed.
