Cellular precOnditioning for Post-Surgical Myocardial Ischemic Complications - Observational Study

Myocardial Infarction | Myocardial Ischemia | Myocardial Injury | Cardiac Complication

The goal of this observational study is to collect health data on people who are at high risk of having heart complications and are having a surgery that is not on the heart. The main questions it aims to answer are:

* Is this study feasible in terms of recruiting enough people to participate in this study?
* How often do heart complications happen in people who are at high risk of heart complications and are having a surgery that is not on the heart?

Participants will have their usual care and will also be asked to:

* Have extra bloodwork done
* Complete some surveys
* Have two echocardiograms (ultrasounds of the heart)
* Continue to follow-up with the research team for one year after their surgery

Researchers will compare how often heart complications occur in this high risk population to a future study where participants will receive stem cells before their surgery.
