title: Incidence and timing of myocardial infarction after total joint arthroplasty.
abstract: Retrospective review of 3471 patients who underwent total joint arthroplasty (TJA) (1479 hips, 1992 knees) to determine the incidence and timing of inhospital myocardial infarction (MI) after TJA. Sixty-three patients (1.8%; 95% CI, 1.4%-2.4%) suffered a perioperative MI occurring at a mean of 3 days post surgery. In multivariate analysis, increased age, body mass index, bilateral TJA, diabetes, and American Society of Anesthesiologists rating 3 were associated with perioperative MI. Our data cautions against hospital discharge within 3 days of surgery.
