عنوان انگلیسی Relationship Between High-Sensitivity C-Reactive Protein and Left Ventricular Perfusion and Function by ECG-Gated SPECT Myocardial Perfusion Imaging
چکیده انگلیسی مقاله Background: We sought to evaluate the relationship between left ventricular (LV) perfusion and function assessed by ECG-gated single-photon emission computerized tomography (SPECT) myocardial perfusion imaging (MPI) and serum high-sensitivity C-reactive protein (hs-CRP).   Methods: The images of 86 patients were reviewed for perfusion/functional defects by visual (subjective) interpretation. Quantitative (objective) LV measurements, including summed stress score (SSS), were calculated with the quantitative gated SPECT/quantitative perfusion SPECT (QGS/QPS) software. Via the quantitative method, the patients were categorized into an SSS<4 group (normal LV perfusion) and an SSS≥4 group (abnormal LV perfusion).   Results: There was no significant difference regarding the mean (±SD) hs-CRP level between normal (1.54±1.6 mg/L) and abnormal (1.88±2.61 mg/L) LV perfusions assessed by visual interpretation (P=0.493). However, by the quantitative (objective) method, the mean (±SD) hs-CRP level was significantly higher in the SSS≥ 4 group than in the SSS< 4 group (1.36±2.08 vs 2.37±2.37; P=0.04). Receiver operating characteristic curve analysis (cutoff value =1 mg/L) distinguished patients with an SSS of 4 or greater with a sensitivity of 69% and specificity of 70% (area under the curve =0.71; P=0.001).   Conclusions: The hs-CRP level had acceptable sensitivity and specificity to determine LV perfusion defects by the objective method but not by the subjective assessment (visual method) of LV perfusion defects.
