Biosignetics - State-of-the Art Heart Auscultation Diagnosis Tools are Highlighted on World Heart Day
Biosignetics Corporation has developed and applied state-of-the art signal processing computational algorithms aiming to stimulate basic research and to teach physicians and medical students to perform “digital” heart auscultation diagnosis during the routine medical checkups. Patent pending Heart Energy Signature has a great potential to become de-facto standard to record, store, compare and track sound based heart diagnosis data.
Exeter, NH (PRWEB) September 28, 2004 -- Cardiac Examination – New Tools are
Available for Basic Research and Medical Education
According to the World
Health Organization (WHO) heart disease and stroke kill some 17 million people a
year, which is almost one-third of all deaths globally. By 2020, heart disease
and stroke will become the leading cause of both death and disability worldwide,
with the number of fatalities projected to increase to over 20 million a year
and by 2030 to over 24 million a year.

According
to Dr Judith Mackay, co-author of the WHO Atlas of heart disease and stroke,
said: “No matter what advances there are in high-technology medicine, the
fundamental message is that any major reduction in deaths and disability from
heart disease and stroke will come primarily from prevention, not just cure.” We
believe that early cardiac physical examination (screening) will become a
fundamental element of any prevention program.
The second release of
Heart Energy Signature phonocardiograph software was launched on 23 September
2004, to coincide with World Heart Day, Sunday September 26, 2004.

Heart Energy
Signature is expected to provide a powerful new tool to stimulate cardiac
auscultation education and non-clinical basic research in Medical Colleges and
Medical Teaching Hospitals around the world. It offers both qualitative and
quantitative way of representing all heart sounds making auscultation findings
easy to document, understand, share, classify and diagnose.

Heart Energy
Signature’s main component is the joint time frequency domain two dimensional
color display of heart signal energy.

Heart Energy
Signature offers a comprehensive solution for the noninvasive screening of the
heart conditions. It allows differentiating changes in heart beat energy
simultaneously in time and in frequency. It makes possible to precisely “X-Ray”
hidden sound morphology. Digital phonocardiograph can only represent heart sound
content changes in time (phonocardiogram). Although extremely useful, such
content can not be used for precise characterization of the heart condition or
for the early heart diagnostics.
Biosignetics software tools based on
the Heart Energy Signature provide an effective way to screen out heart sound
imperfections early on. Our scientists have developed Atlas of Heart Sound
Diseases with over 100 pages of phonocardiograms, heart energy signatures,
spectrograms documenting human heart conditions (stenosis, regurgitation,
splits, clicks, gallops, snaps, rumble, valve prolapse, murmurs, septal defect,
patent ductus arteriosus, atrial septal defect). Resulting heart sound images
are self-referencing and can be easily understood by the physicians, medical
researchers and patients alike.

First
edition of the Atlas will be made available on the Worlds Heart Day, September
26, 2004.
Biosignetics continues its advanced research to develop
ultra-fast, accurate and comprehensive signal processing algorithms and software
tools to process dynamic biosignatures. This will in turn enable early detection
of heart imperfections in their early stages. Company research proposal was
selected to be the semi-finalist at the US Advance Technology Program (ATP)
managed by the National Institute of Standards. ATP Program funds high risk high
payoff path-breaking research from all technology areas.
Biosignetics is
welcoming the medical researchers and practitioners to jointly conduct clinical
research on advancement of sound-based characterization of specific heart
conditions and diseases, interventional procedures and medical
treatments.
