Changes in ischaemia as assessed with single-photon emission computed tomography myocardial perfusion imaging in high-risk patients with diabetes without cardiac symptoms: relation with coronary atherosclerosis on computed tomography coronary angiography

摘要

Aims The study aims (i) to evaluate changes in myocardial ischaemia on single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) after 2 years in a cohort of high-risk patients with diabetes without cardiac symptoms or known coronary artery disease(CAD) and (ii) to assess the value of baseline computed tomography coronary angiography (CTA)-derived coronary atherosclerosis parameters to predict changes in myocardial ischaemia.
