Clinical Trial Summary

The purpose of this study is to determine the relationship between the levels of Ribonucleic acid (RNA) circulating molecules, including ones in extracellular vesicles from different organs in the blood and in the saliva of patients with Acute Decompensated Heart Failure (ADHF) and Chronic Heart Failure (CHF) to see if a new, non-invasive diagnostic test can be developed for heart failure exacerbation.


Description:

The primary objective of this study is to investigate the expression of extracellular vesicle RNAs (evRNAs) during admission for and decongestion of ADHF patients and determine their diagnostic and prognostic potential. The main hypothesis is that these evRNAs are dynamically regulated in response to volume status changes. Thus, the aim is to delineate: i) the utility of salivary evRNA expression in discriminating ADHF from compensated chronic heart failure states in ADHF patients, chronic heart failure patients and controls (n=30 each); and ii) assess changes in expression in ADHF patients during decongestion. Plasma and salivary evRNA levels will be correlated to determine accuracy of salivary Extracellular Vesicles (EVs) to reflect changes in plasma. This is a multi-cohort study that will make use of clinical saliva and plasma samples of 90 subjects across three groups. The first group will consist of 30 patients admitted to the hospital for ADHF (clinical samples will be collected during acute decompensation and after diuresis of ADHF patients). The second group will consist of 30 patients with chronic heart failure who are seen in the outpatient clinic. The control group will also include 30 Supraventricular Tachycardia (SVT) patients recruited through the Electrophysiology Lab (EP). For each group, blood plasma and saliva samples will be obtained.
