简要总结
This prospective observational diagnostic accuracy study investigates the efficacy of the hepatic vein systolic filling fraction (SFF) as a real-time, non-invasive indicator of right ventricular (RV) systolic function in critically ill patients admitted to the intensive care unit.

结局指标
主要结局
Hepatic vein systolic filling fraction (SFF) and Tricuspid Annular Plane Systolic Excursion (TAPSE)
时间窗: within the first 24 hours
Hepatic vein systolic filling fraction (SFF) will be measured using colour Doppler ultrasonography of the hepatic vein. Examinations will be performed within a 5-minute window of transthoracic echocardiography and obtained at end-expiration to minimise the effects of respiratory variation. All patients will be mechanically ventilated, and positive end-expiratory pressure (PEEP) and plateau pressure will be recorded at the time of assessment. Unit: Percentage (%) Right ventricular systolic function will be assessed by measuring tricuspid annular plane systolic excursion (TAPSE) using transthoracic echocardiography at the bedside. Echocardiographic examination will be performed within a 5-minute window of hepatic vein Doppler assessment and obtained at end-expiration to minimise respiratory variation. All patients will be mechanically ventilated, and positive end-expiratory pressure (PEEP) and plateau pressure will be recorded at the time of assessment. Unit: Millimetres mm
次要结局
- Baseline Demographic and Clinical Data, Synchronized Hemodynamic and Respiratory Data, Total length of ICU stay (days) and ICU mortality and the correlation and agreement between the hepatic vein and RV systolic function via TAPSE.(till 28 days after admission)
