ABSTRACT
Objective:
To explore the relationship between septal myocardial metabolism and left ventricular mechanical synchronization in patients with dilated cardiomyopathy (DCM) and left bundle branch block (LBBB) by gated 18F-FDG myocardial metabolic imaging.Methods:
A total of 20 consecutive patients diagnosed for DCM with LBBB from 2010-10 to 2013-05 were enrolled, there were 11 male and 9 female at the mean age of (54±11) years. All patients received gated 18F-FDG myocardial metabolic PET imaging. TrueD software was used to determine the maximal standardized 18F-FDG uptake value (S-SUVmax) and the average standardized uptake value (S-SUVavg). QGS software was applied to conduct left ventricular phase analysis and to detect the cardiac function, left ventricular bandwidth (BW), standard deviation of bandwidth (SD), left ventricular end-diastolic volume (LVEDV), LVESV and LVEF. The relationship between 18F-FDG uptake in septal myocardium with the indexes of phase analysis and the indexes of cardiac function was analyzed.Results:
S-SUVmax and S-SUVavg were respectively negatively related to BW (r=-0.44, P0.05.Conclusion:
In patients of DCM with LBBB, reduced septal myocardial metabolism was closely related to left ventricular mechanical synchronization, gated 18F-FDG myocardial metabolic PET imaging may simultaneously detect both functions, which was important for prognostic evaluation and therapeutic monitoring in clinical practice;phase analysis.
