NCT02364752

Brief Summary

The aim of this 2-part study is to assess B-type natriuretic peptide (BNP) as well as other circulating and imaging biomarkers in myocardial function. Part 1 assesses biomarker levels in healthy participants and participants with cardiac dysfunction. Part 2 assesses BNP and other circulating biomarker levels, and performs imaging in participants with cardiac dysfunction who continued from Part 1. The primary hypothesis is that compared to healthy participants, biomarker levels are elevated in participants with mild/moderate and severe cardiac dysfunction.

Study Arms (3)

Healthy

EXPERIMENTAL

Part 1: Blood is obtained from healthy participants on 3 consecutive days, and participants undergo Cardiac Magnetic Resonance Imaging (CMR) and two-dimensional speckle tracking echocardiography (2DSTE) on one of those 3 days.

Procedure: Blood Draw

Mild/moderate heart failure (HF)

EXPERIMENTAL

Part 1: Blood is obtained from participants with mild/moderate HF on 3 consecutive days, and participants undergo CMR and 2DSTE on one of those 3 days. Part 2: Within 5 days of completing Part 1 participants have a 24 hour loop diuretic withdrawal, and 15 hour 0.9% normal saline infusion; followed by a blood draw, CMR and 2DSTE.

Procedure: Blood DrawProcedure: Loop Diuretic Withdrawal/Salt Load

Severe HF

EXPERIMENTAL

Part 1: Blood is obtained from participants with severe HF on 3 consecutive days, and participants undergo CMR and 2DSTE on one of those 3 days. Part 2: Within 5 days of completing Part 1 participants have a 24 hour loop diuretic withdrawal, and 15 hour 0.9% normal saline infusion; followed by a blood draw, CMR and 2DSTE.
