18F-MFBG Cardiac Imaging for Heart Failure Administration

This is a prospective, single-center clinical study, using18F-meta-fluorobenzylguanidine (18F-MFBG) cardiac PET imaging to present the sympathetic nerve status in heart failure, including ICD implantation. Through follow-up, we analyze the correlation between the distribution of the tracer in the heart and the functions and progression of the patients, including the occurrence of ventricular arrhythmias and sudden cardiac death, And further investigate the guiding value of 18F-MFBG cardiac sympathetic nerve imaging in the screening of ICD implantation patients, including primary and secondary prevention, reducing the cost of ICD implantation and related complications. Furthermore, to evaluate the therapy efficacy for these patients with heart failure using 18F-MFBG cardiac imaging has been considered.
