  • Joint Replacement Surgery Linked With Increased Risk of Heart Attack

    Older adults who have total hip replacement (THR) or total knee replacement (TKR) surgery are at an increased risk of heart attack, say authors of a study that included records of more than 95,000 Danish patients who underwent a primary THR or TKR from January 1, 1998, through December 31, 2007. 

    During the first 2 postoperative weeks, the risk of heart attack was substantially increased in THR patients compared with controls (adjusted hazard ratio [HR] 25.5). The risk remained elevated for 2 to 6 weeks after surgery (adjusted HR, 5.05) and then decreased to baseline levels. For patients with TKR the risk of heart attack also was increased during the first 2 weeks (adjusted HR, 30.9) but did not differ from controls after the first 2 weeks. The absolute 6-week risk of heart attack was 0.51% in patients with THR and 0.21% in patients with TKR.

    The authors say the association was strongest in patients 80 years or older. They could not detect a significantly increased risk in patients younger than 60 years. Additionally, a history of heart attack in the 6 months before surgery increased the risk of new heart attack during the first 6 weeks after THR and TKR surgery, but it did not affect the relationship between THR or TKR and heart attack.

    CARF Webinar: Accessing Evidence for Stroke

    Evidence is increasingly being used as a prerequisite for reimbursement of services and is an ongoing mandate for rehabilitation clinicians. The use of evidence-based practice also can ensure that the most effective treatments are being provided to patients, which is fundamental to cost-effective, appropriate care. On September 18, CARF International will host a 90-minute webinar that will review easy-to-use, easy-to-access options for accessing evidence for stroke rehabilitative services. Upon completion, webinar participants should be able to:

    • Identify reliable research sources on stroke and stroke rehabilitation.
    • Discuss the importance and challenges of knowledge translation.
    • Identify tools that address the concepts of impairment, activity, and participation.
    • Identify tools that clinicians can use to make their patients and clients aware of ongoing clinical trials.

    Register today for Medical Rehabilitation Webinar: Current Stroke Research to Access and Use in Clinical Practice, September 18, noon to 1:30 pm, ET.
