Detecting Pulmonary Hypertension With the Eko CORE 500 Digital Stethoscope

Sponsor: Eko Devices, Inc.

View on ClinicalTrials.gov

Summary

This prospective, observational study will evaluate whether synchronized heart sound (phonocardiogram, PCG) and three-lead electrocardiogram (ECG) recordings (entered as separate interventions in PRS, though collected together in practice) collected with the Eko CORE 500 can help screen for pulmonary hypertension (PH). Adults (≥18 years) undergoing clinically indicated transthoracic echocardiography (TTE) and/or right heart catheterization (RHC) will complete one study visit (\~20 minutes). During the visit, study staff will obtain at least four 15-second CORE 500 recordings (aortic, pulmonic, tricuspid, and mitral areas). The clinical echocardiogram (and RHC, if performed) within ±7 days of the recordings will provide reference labels for the presence and severity of PH; de-identified demographic and clinical data may also be abstracted from the medical record. The primary objective is to develop and validate a software algorithm to detect PH and, where possible, stratify severity using noninvasive PCG+ECG signals. These recordings are investigational data acquisitions for algorithm development only; they are not diagnostic procedures and will not be used for clinical decision-making. Primary performance measures are sensitivity and specificity versus echocardiogram and RHC references. No clinical decisions will be based on the investigational algorithm, and no changes to standard care are required. The study plans to enroll up to \~1,513 participants to obtain approximately 1,375 evaluable datasets across multiple outpatient sites.

Interventions

DIAGNOSTIC_TEST

Eko CORE 500 phonocardiogram (PCG) recording

Noninvasive acquisition of heart sound (phonocardiogram, PCG) recordings using the FDA (U.S. Food and Drug Administration)-cleared Eko CORE 500 digital stethoscope. At least four 15-second recordings are collected at standard auscultation sites (aortic, pulmonic, tricuspid, mitral). Recordings are used solely for investigational algorithm development and are not used for diagnostic or clinical decision-making.

DIAGNOSTIC_TEST

Eko CORE 500 three-lead electrocardiogram (ECG) recording

Noninvasive acquisition of three-lead electrocardiogram (ECG) signals using the FDA-cleared Eko CORE 500 digital stethoscope. Recordings are obtained simultaneously with PCG at auscultation sites. Data are used solely for investigational algorithm development and are not intended for diagnostic use.
