UMIN-CTR Clinical Trial

Basic information
Public title	Significant Correlation between Renal 123I-Metaiodobenzylguanidine Scintigraphy and Muscle Sympathetic Nerve Activity in Patients with Heart Failure with Reduced Ejection Fraction
Acronym	Study of renal MIBG in HFrEF patients
Scientific Title	Significant Correlation between Renal 123I-Metaiodobenzylguanidine Scintigraphy and Muscle Sympathetic Nerve Activity in Patients with Heart Failure with Reduced Ejection Fraction
Scientific Title:Acronym	Study of renal MIBG in HFrEF patients
Region	Japan

Condition
Condition	HFrEF
Classification by specialty	Cardiology
Classification by malignancy	Others
Genomic information	NO

Objectives
Narrative objectives1	In this study, we hypothesized that HFrEF patients whose sympathetic nerves and humoral factor interaction are accelerated by pressure overloading, the dynamics of 123I is more likely to be observed. We compared renal MIBG and sympathetic nerve parameters and heart function indicators and examined how renal MIBG is related to cardiac function and circulatory dynamics.
