Design outcomes

Primary

MeasureTime frame
1) Comparison of the 3-day average RST before discharge between cardiac event and non-event groups. 2)Optimal cutoff value of the 3-day average RST before discharge for predicting cardiac events.

Secondary

MeasureTime frame
1)Comparison of post-discharge heart failure-related hospitalization and mortality between two groups divided by the median 3-day average RST. 2)Comparison of post-discharge heart failure-related hospitalization and mortality between two groups based on RST change rate.
