OBJECTIVES: The purpose of this study was to estimate the value of preoperative electrocardiographic (ECG) monitoring in predicting postoperative @entity299 in @entity1 undergoing abdominal aortic surgery. DESIGN: A prospective open study. SETTING: University Hospital. MATERIALS: One hundred consecutive @entity1 were studied before aortic or aortofemoral surgery by ambulatory ECG monitoring for 24 hours. CHIEF OUTCOME MEASURES: An ischaemic episode by ECG criteria was defined as a > or = 1 mm horizontal or downsloping ST segment @entity308 measured 60 msec after the J point and persisting for at least 40 sec. MAIN RESULTS: Twenty-four @entity1 had preoperative ambulatory ischaemia. Twenty @entity1 had postoperative @entity299 including three with fatal @entity583 , one with a nonfatal @entity1188 , eight with @entity1459 , three with @entity4 and five with @entity955 . Sixteen out of 24 (67%) @entity1 with ambulatory ischaemia had postoperative @entity299 (p < 0.01). Only four events occurred among 76 @entity1 without ischaemia (p < 0.005). The sensitivity of ambulatory ischaemia predicting @entity299 was 80% with a specificity of 90%, the predictive value of ischaemia was 67% and the predictive value of a negative result was 95%. CONCLUSIONS: Preoperative ECG monitoring for @entity296 could non-invasively identify @entity1 at high risk for postoperative cardiac morbidity and mortality after vascular surgery.
