Summary

This study looks at 1,200 adults after heart surgery to see if large swings in blood pressure and poor blood flow to tissues are linked to serious problems like stroke, heart attack, or kidney failure. Researchers will monitor patients in the ICU for at least 12 hours after surgery. The goal is to find better ways to spot and prevent complications early.
