Study Demonstrates High Accuracy of Ventric Health’s Heart Failure Detection Tool

A new study indicates Ventric Health’s Vivio System is the first technology to accurately and non-invasively measure left ventricular end-diastolic pressure (LVEDP). A manuscript detailing outcomes from a U.S. Food and Drug Administration (FDA) validation trial was published in the Journal of the American Heart Association.

The FDA-approved Vivio System empowers earlier heart failure (HF) detection by enabling LVEDP measurement non-invasively in a five-minute test performed in a primary care office visit. The goal? Earlier intervention before quality of life deteriorates.

The study that included 728 patients recruited at eight U.S. sites concluded the Vivio System achieved 80% sensitivity and 83% specificity in non-invasively detecting HF using LVEDP. The system demonstrated six times greater sensitivity than echocardiography and twice the sensitivity of B-type natriuretic peptide (BNP) blood tests, two commonly used and guideline-accepted, non-invasive HF measurement methods. In the study, the Vivio System algorithm was trained with, and tested against, the most accurate LVEDP data available obtained from simultaneous recordings using an indwelling Millar Mikro-Cath catheter in the left ventricle.

“The Vivio System can accurately detect elevated LVEDP and has the potential to significantly improve early detection of HF in the outpatient setting,” the study authors noted. “Integrating the Vivio System into routine care pathways may shift HF diagnosis from reactive to proactive management, particularly for individuals with comorbidities such as diabetes mellitus or chronic kidney disease. By identifying patients before HF decompensation occurs the Vivio System may support earlier initiation of guideline-directed medical therapy (GDMT), which can improve outcomes and reduce hospitalizations.”

A recent study of more than 2,000 patients published in JACC: Advances showed the Vivio System accurately identified previously undiagnosed HF patients who could benefit from further treatment to improve or manage their condition. Almost one-quarter of the patients identified by the Vivio System as having elevated LVEDP reported substantial symptoms and impaired health status associated with higher risks of hospitalization and death.

Additionally, a study of 1,179 patients presented at the Heart Failure Society of America Annual Scientific Meeting last fall found that 71% of previously asymptomatic patients with a high risk for developing HF (Stage A HF patients) who tested positive for elevated LVEDP using the Vivio System also reported concerning symptoms on the KCCQ-12 that led to their reclassification as Stage C HF patients.

Elevated cardiac filling pressures are one of the earliest HF signs and often precede the development of symptoms, physical findings, and structural left ventricle remodeling. Elevated filling pressures, assessed by the direct LVEDP measurement is independent of HF type but requires an invasive procedure and therefore is not practical to apply in the public health context, according to the authors.

The Vivio System screens for elevated left ventricular end-diastolic pressure, (LVEDP) quickly and non-invasively using a modified blood pressure cuff, single-lead Bluetooth-enabled ECG, and an unbiased, physics-based algorithm to compute LVEDP. It is designed to assess patients at high risk of HF—those older than 65 with diabetes and/or chronic kidney disease—in a primary care setting. The technology has demonstrated greater sensitivity than other non-invasive methods currently used to measure LVEDP, including blood tests and echocardiography. As a non-invasive test, the Vivio System does not present the risks or costs of LVEDP measurement using invasive cardiac catheterization or device implantation.

More than 24,000 patients have been tested with the Vivio System to date. Practices using the Vivio System have reported an increase in first-time HF diagnosis in primary care, decreased hospitalization and ER visits, and improved patient medication compliance and quality of life.¹

The Vivio System screening fits into a typical primary care office visit, with results immediately available and actionable in the same visit, so a physician can quickly intervene with medication, a cardiology referral, or other necessary HF management strategy at their discretion.

Ventric Health aims to empower earlier heart failure diagnosis, thus enabling earlier intervention and better patient cardiac health. Its Vivio System helps non-invasively diagnose HF within a primary care environment, moving screening to a more accessible and less expensive point of care, and away from the emergency room and in-patient hospital setting. By doing this, the company intends to enable value-based care organizations and healthcare teams to lower costs and improve patient lives.
