Heart attacks after surgery, medically known as postoperative myocardial infarctions, occur relatively infrequently but are a serious concern. The incidence varies widely depending on patient risk factors and the type of surgery. Generally, high-risk surgeries, like those involving the heart or arteries, have a higher risk. For major noncardiac surgery, the risk is estimated to be about 1% to 5%, depending on the patient's health and specific risk factors such as a history of heart disease, age, and the nature of the surgery.
