“…60 For patients with cardiac indications, observational studies report abnormal echocardiography findings in 7.5-25.2% of patients, 89 -92 leading to cancellation of surgery in 0.8% of cases (Category B2 evidence). 92 In selected or indicated patients, abnormal stress or exercise test findings were reported for 15.2-61.9% of patients, 74,[93][94][95][96] leading to additional cardiac testing in 39.5% of patients with abnormal findings (Category B2 evidence). 96 A retrospective nonblinded study of vascular surgery patients administered a preoperative stress test reports a reduced 30-day mortality compared with patients not administered a preoperative cardiac test (Category B2 evidence).…”

“…Because intravenous dobutamine increases myocardial oxygen demand in a fashion similar to exercise, it is advantageous in patients who may need a cardiac stress test but cannot exercise due to peripheral vascular disease, physical incapacitation, or chronic deconditioning (28). For this reason, dobutamine stress is useful for assessing preoperative risk in patients who need noncardiac vascular surgery but cannot exercise due to claudication (29).…”

“…For patients with indicated cardiac evaluations, abnormal findings were found with angiography: 22.5-47.0% of cases (N ϭ 4 studies) [117][118][119][120] ; echocardiography: 7.5%-50.0% of cases (N ϭ 5 studies) [121][122][123][124][125] ; stress or exercise tests; 15.0 -71.0% of cases (N ϭ 3 studies). 105,126,127 Changes in clinical management were not uniformly reported.…”
