New Knees and Hips Cut Heart Risk

Heart DiseaseAt the annual meeting of the American Academy of Orthopedics in New Orleans, Bheeshma Ravi, M.D., an orthopedics resident at the University of Toronto, reported that patients who underwent knee and hip replacements were able to dramatically reduce their risk of a heart attack or stroke over a seven year period. He followed 153 patients who were high risk for cardiovascular disease and noted the major risk reduction.

Some of the improvement in risks were assumed to be due to the increased mobility and increased activity the recipients were able to enjoy. The increased physical activity improves cardiac health. While physical activity is one explanation, the reduction in pain, stress, use of painkillers and inflammation is another set of potential reasons. With pain comes use of more nonsteroidal anti-inflammatory medications which have been implicated in the development of acute heart attacks.

In our medical practice we often see senior citizens who are healthy enough to undergo a joint replacement but are too fearful to proceed with the surgery. This particular study provides additional evidence that replacing the inflamed joint and resuming activity is the correct choice to make.
