Background and objectives

Since the role of positron emission tomography (PET) scanning in diabetes is not clear, this study sought to assess the usefulness of PET scanning for viability in this patient group.

Methods

Forty-four per cent insulin-treated, and 56% non-insulin-treated diabetic patients with severely impaired left ventricular function (LVEF 29± 9%) underwent first coronary artery bypass grafting (CABG). Pre-operative viability was assessed by PET scan.

Results

Eighty-two per cent of patients received 3 grafts. Twenty-seven patients were discharged home and followed for a mean 3.5±1.6 years. Postoperative LVEF improved to 40±9 (p<0.0001). Multiple regression analysis indicated that the only variable that predicted improvement in global LV function was presence of hibernating segments at PET scan. The single variable that predicted deterioration of LVEF was the number of segments with reduced perfusion and metabolism at PET scan.

Conclusion

PET scan is an accurate tool for prediction of global left ventricular function recovery following CABG in people with diabetes.

Key Words: coronary artery disease • diabetes,impaired left ventricular function • hibernating myocardium • bypass surgery.
