Noninvasive evaluation of ischaemic heart disease: myocardial perfusion imaging or stress echocardiography?

Abstract

Stress echocardiography and myocardial perfusion imaging are commonly used noninvasive imaging modalities for the evaluation of ischaemic heart disease. Both modalities have proved clinically useful in the entire spectrum of coronary artery disease. Both techniques can detect coronary artery disease and provide prognostic information. Both techniques can identify low-risk and high-risk subsets among patients with known or suspected coronary artery disease and thus guide patient management decisions. In patients with acute myocardial infarction, both techniques have been used to identify residual viable tissue and predict improvement of function over time. In patients with chronic ischaemic left ventricular (LV) dysfunction, viability assessment with either modality can be used to predict improvement of function after revascularisation and thus guide patient treatment
