This is an observational study that follows patients before and after they receive heart surgery — either bypass surgery, valve repair, or valve replacement. Researchers want to understand which patient characteristics and blood markers can predict who will have complications after surgery, so they can help doctors identify high-risk patients and improve care.
Heart surgery is common, but some patients recover smoothly while others develop serious complications like irregular heartbeats or heart damage. By studying patients over time and examining their blood and tissue before and after surgery, doctors hope to learn how to predict and prevent these complications.

You would have blood and tissue samples collected before your scheduled surgery and at follow-up visits afterward. Researchers will track your recovery, medical outcomes, and any complications over time. The study will examine your samples in the lab to look for patterns that predict how well you'll recover. You'll continue your normal care with your heart surgeon — this study simply observes and learns from your journey.
