New Risk Factors for Cardiovascular Problems After Joint Surgery Identified

The results, reported in the July issue of Arthritis and Rheumatism, come from a case-control study of 209 patients who experienced an MI, heart failure, unstable angina, arrhythmia, symptomatic hypotension, or pulmonary embolism during the surgical admission for TJR, and 209 matched patients who did not have cardiovascular complications.

In line with prior findings, older age at surgery (odds ratio, 1.7), history of arrhythmia (OR, 2.6), and history of coronary artery disease, MI, heart failure, or valvular heart disease (OR, 1.6) all increased the risk of cardiovascular complications.

The strongest risk factor, however, was one of the newly identified ones, bilateral surgery, which increased the risk by 3.5-fold. Revision surgery also greatly increased the risk (OR, 2.2).

"Clinicians can use this information to better estimate the risk of cardiovascular complications following TJR surgery," Dr. Katz said, "and, ultimately, to prevent and better manage these complications."
