While the vast majority of abnormal Q waves are due to myocardial infarction (MI), a significant number are due to other causes. It depends on how “big” the Q wave is.
This is best checked via a cardiology consultation, a stress ECHO, and probably a CTCA Scan. If you had an MI in the past, you can also calculate your risk for heart disease.
If no serious heart disease is found and your heart function is OK, it is highly unlikely that your surgery gets canceled. However, a Roux-en-Y gastric Bypass is a big operation, and thus more likely to cause troubles if a person has Coronary Artery Disease (CAD). Therefore it is wise, to get checked out beforehand!
Hope this helps,
