Joint replacement surgery may impact your heart

Doctor and nurseThe risk of a heart attack may be increased shortly after total hip or knee replacement surgery, according to research.

A Danish study followed patients who had undergone joint replacement surgery. Heart attack risk was found to increase 25-fold in the first two weeks after hip replacement and 31-fold for knee replacement.

Doireann Maddock, our Senior Cardiac Nurse, said:  “This study examines a potentially interesting link, but it ignores key risk factors for a heart attack such as smoking, blood pressure and body mass index.

If you're due to have knee or hip replacement surgery, don’t be overly alarmed by these findings

"Further research into the relationship between joint replacement surgery and heart attacks must take into account the part played by these risk factors. We also need to acknowledge the impact of general anaesthesia, which might have contributed to the increased heart attack risk.

“It’s important to note that these findings are age-specific - people aged over 80 had the most pronounced increase in risk, but no increase was found in those younger than 60.

“If you are due to have knee or hip replacement surgery, don’t be overly alarmed by these findings. You can speak to your GP or practice nurse and get a free heart health check if you are in any way concerned about your risk of heart disease.”

This study was published online in the Archives of Internal Medicine.
