Heart surgery has risks, even though its results often are excellent. Risks include:
Memory loss and other issues, such as problems concentrating or thinking clearly, may occur in some people.
These problems are more likely to affect older patients and women. These issues often improve within 6–12 months of surgery.
In general, the risk of complications is higher if heart surgery is done in an emergency situation (for example, during a heart attack). The risk also is higher if you have other diseases or conditions, such as diabetes, kidney disease, lung disease, or peripheral arterial disease (P.A.D.).
