Sympathetic Innervation of the Heart and Cardiac Resynchronization Therapy(CRT) (PET-CRT)

University Medical Center Groningen (UMCG)

Status: Withdrawn

Conditions: Sympathetic Innervation; Chronic Heart Failure

Study type: Observational

Funder types: Other

Identifiers

NCT00567645

Details and patient eligibility

About

The purpose of this study is to assess whether baseline sympathetic innervation in patients with chronic heart failure (CHF) is predictive for response to cardiac resynchronization therapy (CRT). And to assess whether response to CRT coincides with restoration of regional sympathetic innervation.

Sex: All

Ages: 18 to 85 years old
