Non-invasive diagnosis of coronary artery disease by 123I-BMIPP/201TlCl dual myocardial SPECT in patients with heart failure.

Background/objectives: Detecting the presence of coronary artery disease (CAD) is critically important in managing patients with heart failure of uncertain cause. The recently introduced 123I-BMIPP/201TlCl dual myocardial single-photon emission computed tomography (dual SPECT) is potentially a non-invasive diagnostic tool in detecting ischemic heart disease. The aim of our study is to evaluate the efficacy of detecting CAD by dual SPECT in patients with heart failure.
