Özet

ObjectiveThe aim of this study was to evaluate the diagnostic and prognostic efficacy of gated single-photon emission computed tomography (GSPECT) in patients with acute chest pain and to compare quantitative GSPECT parameters and the coronary angiographic SYNTAX score.Materials and methodsA total of 168 patients who presented with clinical symptoms of acute chest pain were enrolled in the study. Study participants were divided into two groups according to the risk of acute coronary syndrome (ACS): low-intermediate and high risk. All participants underwent rest or stress-GSPECT (R/S-GSPECT). Coronary angiography was performed in all high-risk patients and the SYNTAX score was determined. All patients were followed for 243 months and monitored for the occurrence of major adverse coronary events (MACE).ResultsAmong patients with low-intermediate ACS risk, R-GSPECT and S-GSPECT were associated with 100 and 86% sensitivity, 99 and 98% specificity, 100 and 98% negative predictive value, 80 and 86% positive predictive value, and 98 and 97% accuracy, respectively. At follow-up, MACE occurred in 16 patients. Among high-risk patients, GSPECT quantitative parameters were the most significant predictors of MACE in Cox regression analysis.ConclusionR/S-GSPECT, a noninvasive diagnostic method, is associated with an excellent safety profile and exceptional diagnostic and prognostic accuracy in cases of ACS.
