Knee Hip Replacement Surgeries Linked to a Greater Risk for a Heart Attack

According to the findings reported in the journal Arthritis & Rheumatology, dated August 31, 2015, the scientists collected data on nearly 14,000 people over the age of 50 having osteoarthritis who had a total knee replacement. The authors also collected data on more than 6,000 people over the age of 50 having osteoarthritis who had a total hip replacement.

Based on comparison between the patients  and those who didn’t have the procedures, it was found that the changes of a heart attack were: 

  • > eight (8) times greater in the first 30 days of total knee replacement surgery
  • > four (4) times greater  during the month following total hip replacement surgery.

But the researchers noted that the findings shouldn’t deter people from having these surgeries.

“Overall, neither knee or hip replacement increases the risk of heart attack over the entire follow-up period in our study, even though the risk was substantially increased shortly after surgery,” he said. “This risk should not keep a patient from having either surgery.”

“The reasons for increased risk of heart attack for these and other types of surgery are many, and to date approaches such as use of heart medications, such as aspirin, beta blockers and alpha blockers, have generally not been successful in lowering the risk,” Dr. Gregg Fonarow, a professor of cardiology at the University of California, Los Angeles, said.
