Design outcomes

Primary

Measure	Time frame
The relation between E/GLS and pulmonary artery wedge pressure, and between inferior vena cava diameter and central venous pressure.	—

Secondary

Measure	Time frame
(1) The relations between echocardiographic parameters and pulmonary artery wedge pressure. (2) The relations between the cardiovascular events indicated below and each echocardiographic parameters. A. total death B. cardiovascular death C. hospitalization due to cardiovascular events including heart failure D. the elevation of the level of type-B natriuretic peptide (3) The relations between echocardiographic parameters and pulmonary artery wedge pressure in specific subgroups, such as patients with certain diseases.	—
