What are the recommendations for stress testing and advanced imaging for initial diagnosis in patients with suspected SIHD who require noninvasive testing?
Class I Recommendations are: 1) Exercise ECG is reasonable in patients with intermediate pretest likelihood of SIHD who are able to exercise. 2) Stress imaging is reasonable in patients with intermediate pretest likelihood of SIHD who are unable to exercise and in patients with high pretest likelihood of SIHD. 3) CCTA is reasonable in patients with intermediate pretest likelihood of SIHD if ECG and stress imaging are inconclusive. 4) CMR is reasonable in patients with high pretest likelihood of SIHD if ECG and stress imaging are inconclusive.
