ABSTRACT

Introduction: The left ventricular ejection fraction (LVEF) is a parameter that reflects the myocardial systolic function. Its measurement is of great importance to establish the diagnosis, treatment and prognosis of different cardiovascular diseases. There are several non-invasive methods such as echocardiography, magnetic resonance imaging, Gated-SPECT for the measurement of ventricular volumetric and the ejection fraction of the left ventricle. Objective: The objective of this study was to determine the normal values ​​of left ventricular volumes and LVEF using Gated-PET-13N-Amonia in Mexican population. Material and methods: We included patients with normal Gated-PET13N-Ammonium myocardial perfusion study. Left ventricular volumes and ejection fraction were obtained. Images were analyzed in QPS-QGS ^®Cedars Sinai ^®. The variables were expressed in mean and standard deviation. Results: A total of 78 patients were included. The end-diastolic volume (EDV) at rest was of 84.9±28.2 mL, the end-systolic volume (ESV) 28.2±20.1, the stroke volume (SV) 56.8±12.8 mL and the LVEF 68.7±%. The stress EDV was of 96.3±31.7 mL, the stress ESV 32.1±21.7 mL, the SV 64±13.9 mL and the LVEF 68.3±8.75%. Conclusion: The measurement of left ventricular volumes and ejection fraction obtained by the PET ¹³N-Ammonium perfusion study is feasible and should be considered as an additional diagnostic tool.
