  • Knee & hip replacement surgery increases heart attack risk!

New research claims arthroplasty patients are more prone to have a myocardial infraction.

Recently research was carried out on osteoporosis patients. The researchers carried out the findings in Boston. The researchers found patients undergoing knee and hip replacement were at increased risk of heart attack.

Knee and hip replacement surgery is called arthroplasty. Patients who have osteoporosis and undergo arthroplasty are prone to heart attack. Especially myocardial infractions can be caused due to the surgery.

The risk is especially increased in the early post-operative period. The risk of heart attack did not exist in the long term. But the risk of blood clots in veins and lungs remained for years. After the early post-operative period the risk of venous thromboembolism was especially high. 

The findings of the research were published in Arthritis & Rheumatology. Arthritis & Rheumatology is a journal of the American College of Rheumatology (ACR). Due to Osteoarthritis knee and hip bone deteriorate.

Therefore surgery may be the only option to relieve pain and restore mobility. More than 27 million Americans over the age of 25 develop osteoarthritis. Every year 1.8 million arthroplasty procedures are performed every year. 

"While evidence shows that joint replacement surgery improves pain, function, and quality of life for the osteoarthritis patient, the impact of cardiovascular health has not been confirmed," explains lead study author Yuqing Zhang, D.Sc., Professor of Medicine and Epidemiology at Boston University School of Medicine in Boston, Massachusetts.

"Our study examines if joint replacement surgery reduces risk of serious cardiovascular events among osteoarthritis patients."

The present study was a cohort study design. A total of 13,849 patients who underwent total knee replacement surgery were studied. A control of 13,849 was also established. The patients were 50 years of age or older.

All the patients were diagnosed with knee or hip osteoarthritis from January 2000 and December 2012. It was found 306 patients in the arthroplasty group had a myocardial infraction. While 286 in the control group also developed myocardial infarction.

The research was led by Yuqing Zhang. According to Dr. Zhang it is the first study to provide population based evidence.  

"Our findings provide the first general population-based evidence that osteoarthritis patients who have total knee or total hip replacement surgery are at increased risk of heart attack in the immediate postoperative period," concludes Dr. Zhang.

"The long-term risk of heart attack was insignificant, but risk of blood clots in the lung remained for years after surgery to replace a hip or knee damaged by osteoarthritis."
