Cardiac risk stratification using dipyridamole myocardial perfusion imaging and ambulatory ECG monitoring prior to vascular surgery

ACC/AHA 2007 Guidelines on Perioperative Cardiovascular Evaluation and Care for Noncardiac Surgery

“…The frequency of abnormal ST-segment changes observed in 869 patients reported in 7 series was 25% (range 9% to 39%). 42,[273][274][275][276][277] The positive and negative predictive values for perioperative MI and cardiac death are shown in Table 9. In 2 studies, preoperative ST changes had a predictive value similar to dipyridamole myocardial perfusion imaging.…”

“…In 2 studies, preoperative ST changes had a predictive value similar to dipyridamole myocardial perfusion imaging. 275,278 Although the test has been shown to be predictive of cardiac morbidity, there are several limitations. Differences in the study protocols (24 versus 48 hour, ambulatory versus in-hospital monitoring) may account for the variability in the predictive value of the test.…”
