High prevalence of coronary artery calcification in Saudi patients with normal myocardial perfusion

Normal single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) has a high negative predictive value for ischemic heart disease. Thus, the presence of subclinical coronary atherosclerosis detected by coronary artery calcification (CAC) score in patients who have undergone SPECT MPI is unknown
