About

The clinical feasibility of 18F-FMBG cardiac PET imaging will be observed in sympathetic nervous system activity in patients with heart failure, predicted cardiac events, guided ICD implantation, and evaluated therapy efficiency.

Full description

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.

Enrollment: 100 estimated patients
