Supports selective dipyridamole-thallium scanning in intermediate-risk vascular surgery patients; confirms combined clinical-imaging stratification for postoperative risk.
Does preoperative cardiac risk stratification using clinical indices and dipyridamole-thallium scanning predict postoperative cardiac complications in patients having peripheral vascular surgery?
Clinical risk indices can identify patients at very low or high risk for cardiac complications after peripheral vascular surgery who do not need further testing, while dipyridamole-thallium scanning is useful for further risk stratification in intermediate-risk patients.
