Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to understand changes in heart function (how the heart pumps blood) and blood flow in people who receive general anesthesia during surgery. The researchers are particularly interested in the heart function and blood flow changes in people who experience low blood pressure (hypotension) after receiving anesthesia.
