AVENTUSOFT L.L.C — Department of Health and Human Services SBIR Phase I: 102

Description

DESCRIPTION provided by applicant This SBIR Phase I project will develop a novel mobile framework to measure left ventricular ejection fraction as a marker for systolic dysfunction using automated non invasive analysis of cardiac signals Heart disease is the leading cause of death for men and women accounting for more than one third of all U S deaths In total costs associated with cardiovascular disease in the U S were estimated to be $ billion making it the costliest health problem facing the nation In addition it occurs disproportionately among minority and health disparity populations For example heart failure related deaths are higher among African Americans than among whites Decreased ejection fraction is a marker of left ventricular systolic dysfunction the most common type of heart failure Overall cardiac health can be significantly improved by proper triage at the primary care level by determination of the ejection fraction without requiring a D echo cardiogram It will provide health care professionals with point of care technology to guide diagnostic monitoring and therapeutic efforts Portable device capability makes it even more accessible and readily available without high costs As the technology being developed does not require skilled operators or specially trained physicians it will allow healthcare providers to measure ejection fraction within their normal medical training We have developed a revolutionary new technology through a Department of Defense Defense Advanced Research Projects Agency DARPA two year Phase II effort that enables measurement of ejection fraction using the cardiac sound signals from each of the four heart valves measured at the chest wall It is based on the technique of separating and localizing sounds known as auditory scene analysis to extract information from the cardiac sounds The scope of the science proposed in this SBIR project is to develop a novel diagnostic framework using our specially engineered accelerometer and electrocardiogram transducer system combined with the novel algorithm technology to run on a smartphone or tablet for a portable and cost effective solution Resource poor communities across the globe lack access to quality healthcare arising from shortages in medical expertise and poor availability of medical diagnostic devices In recent years mobile phones have become increasingly advanced and ubiquitous The mobile framework developed through this project is a tremendous opportunity to provide low cost diagnostics to under served populations The benefit of this pioneering work is the development of a low cost and portable solution that can be used to diagnose systolic dysfunction and thus enable improved screening during routine annual checkups doctor visits at community medical screenings classes and health fairs leading to healthier communities It will make measuring ejection fraction will be as routine as measuring blood pressure In Phase I we will evaluate the clinical relevance through user trials Followed by clinical trials in the Mississippi delta region and the Florida region buildin the required partnerships and joint collaborations to help create a commercially successful product PUBLIC HEALTH RELEVANCE Overall this project provides direct relevance to public health by facilitating new insights through the development of a novel mobile framework to be used in current clinical practice for non invasive direct assessment of the ejection fraction The novel biologically inspired device will significantly impact the current known methods for detection monitoring prevention and treatment of systolic dysfunction and support evidence based clinical practice The project will help reduce health disparities in the area of heart disease assist in providing preventive cardiac care assist in improving access to care assist in early diagnosis of the risk of heart diseases and it will significantly impact the current known methods technologies treatments and address critical barriers to progress in the field
