Cardiac Imaging Tests Before Low-Risk Outpatient Surgery
Cardiac stress tests, such as echocardiograms, CT Scans and MRIs, are used to test how well the heart works when it is stressed. They can be useful tests before a patient has a surgical procedure which is likely to stress the heart. Outpatient surgical procedures such as colonoscopy, cataracts, biopsies, or endoscopies are considered to be low risk. They put very little stress on the heart and research shows they do not require cardiac stress tests before the surgery.
