ClinConnect Summary

This clinical trial is studying how the movement of the diaphragm, the main muscle used for breathing, can help predict complications after heart surgery. After cardiac surgery, some patients can develop problems with their lungs, known as Postoperative Pulmonary Complications (POPCs). Researchers want to see if measuring how well the diaphragm expands when breathing can help identify patients at risk for these complications. They will use a special ultrasound technique to monitor diaphragm movement in real-time, which could lead to quicker interventions if needed.

To participate in this study, you must be over 18 years old and scheduled for elective heart surgery. Certain patients, such as those with specific pre-existing conditions, those undergoing emergency surgeries, or those needing heart transplants, are not eligible. If you join the trial, you can expect to have your diaphragm's movement monitored before and after your surgery, which may help improve care for future patients. Your participation could contribute to better understanding and management of lung issues following heart surgery.
