Outcome following surgery for proximal femur fractures in patients with recent myocardial infarction

Abstract

The mortality following surgery in patients with a recent MI is high. Standard advice is to wait for a minimum of 6 months. In urgent situations, this may not be possible. From Jan 2003 to Aug 2004, 10 patients were admitted with fracture neck of femur and a recent MI proven by ECG changes or raised troponin. There were 7 females. The mean age was 79.5 yrs (59–95yrs). The premorbid mobility and co-morbidities were noted. Echocardiography was done in all patients preoperatively to assess the cardiac function. All patients were seen by physicians and anaesthetist pre-operatively. The mean time from infarction to operation was 11.5 days (3–23 days). The patients underwent either Thompsons hemiarthroplasty or DHS. The anaesthetic was performed by a consultant. Most patients received spinal anaesthesia (7/9). The anaesthetic records could not be found for 1 patient. 6 patients died within a month and 1 patient died within 6 month of operation. Despite thorough preoperative work-up and consultant anaesthesia, the mortality following surgery for proximal femur fractures in patients with recent myocardial infarction is 70% at 6 months. To our knowledge, there are no published mortality figures for this situation. This is much higher than the reported mortality following proximal femur fracture.
