BACKGROUND: The @entity417 associated with perioperative blood conservation has raised concerns regarding the safety of these strategies in @entity1 with @entity65 . Therefore the relationship between hematocrit level and @entity741 episodes in a group of elderly @entity1 undergoing elective noncardiac surgery was studied. STUDY DESIGN AND METHODS: One hundred ninety @entity1 undergoing radical prostatectomy were randomly assigned to one of three blood conservation groups: preoperative autologous blood donation, @entity697 , and preoperative @entity1307 therapy with @entity697 . @entity1 underwent ambulatory electrocardiography monitoring to evaluate for @entity741 at randomization (baseline), 7 days preoperatively, throughout surgery, and for 24 hours after surgery. RESULTS: Myocardial @entity63 episodes occurred in 61 (34%) of 181 evaluable @entity1 . @entity1 with hematocrit levels < 28 percent immediately after surgery were significantly (p = 0.05) more likely to have intraoperative and postoperative ECG @entity63 episodes. Intraoperative @entity63 and @entity591 correlated (r = 0.21, p = 0.008) with hematocrit levels. Hematocrit levels after surgery were associated with postoperative @entity63 (r = 0.14, p = 0.03) and duration of @entity741 episodes (r = 0.14, p = 0.04). After adjusting for other risk factors, intraoperative @entity591 episodes, hematocrit level < 28 percent immediately after surgery, and risk factors for @entity453 were independently associated with the likelihood of intraoperative @entity63 (r = 0.36, p = 0.002, area under receiver operating characteristic curve = 0.73). Similarly, @entity591 episodes and hematocrit levels < 28 percent immediately after surgery were independently associated with @entity63 episodes during the first postoperative day (r = 0.30, p = 0.004, area under receiver operating characteristic curve = 0.71). CONCLUSION: A hematocrit level < 28 percent is independently associated with risk for @entity741 during and after noncardiac surgery. Avoidance of @entity299 may require higher transfusion thresholds, closer attention to @entity591 , or better monitoring for @entity63 .
