Objectives
Cardiac output (CO) is an important hemodynamic parameter in the treatment of the heart failure. Conventionally, this is obtained at bedside by the thermodilution technique with an invasive procedure such as pulmonary artery catheter. However, estimated continuous cardiac output (esCCO) and echocardiographic (echoCO) method are completely noninvasive measurement of CO. The study aims to do a comparison between these two namely esCCO and echo CO methods.
Methods
This prospective observational study includes 24 outpatients (18 male, 6 women) with ejection fraction <40%. Measurement of esCCO and echoCO was performed in all patients. Statistical analysis was carried out by Pearson regression, Bland and Altman analysis.
