Abstract
Background: The aim of the present study was to compare the myocardial perfusion imaging (MPI) with [99mTc]tetrofosmin stress — rest single-photon emission computer tomography (SPECT) of patients with epilepsy with matched control individuals. Material and methods: All 29 adult epileptic patients were receiving antiepileptic drugs (AEDs) for epilepsy. Thirty-two individuals matched for gender and age consisted of the control group. MPIs SPECT were performed, and myocardial summed scores were obtained during stress (SSS) and rest (SRS) images. Abnormal MPI was considered when SSS was ≥ 4. In addition, the difference (SDS) between SSS and SRS was also assessed, which represents a rate of reversibility after stress. Results: Twenty of 29 (68.97%) patients with epilepsy had abnormal MPI and 14/32 (43.75%) of the controls (p = 0.04). Among males, 18/23 patients and 11/25 controls had abnormal MPI (p = 0.01), with quite a significant difference for mean SSS between male patients and controls (p = 0.002). Furthermore, SDS comparison showed that irreversible abnormalities were more common in patients than in control individuals. A difference of inadequately compensated myocardial ischemia between patients treated with enzyme inducing AEDs and patients treated with valproic acid was also detected. Conclusions: Single-photon emission computer tomography (SPECT) may detect increased risk for coronary artery disease and further cardiovascular events in patients with epilepsy. Our findings favor the conclusion that SPECT could be used for the early identification of cardiovascular comorbidity in epilepsy.
