Total knee and hip replacement surgeries may temporarily increase a patient's risk of myocardial infarction during the period immediately after the procedure, researchers said.

The effect was greatest during the 6 weeks following total hip replacement surgery among patients aged 80 and older, who faced a 25.3% increased risk of suffering acute myocardial infarction, according to the study.

The risk was more pronounced in female patients of all ages, for which researchers reported a 21.7% heart attack risk increase compared with 12.8% for male patients.
