Eko receives FDA clearance for heart murmur analysis algorithm

Eko receives FDA clearance for heart murmur analysis algorithm

Smart stethoscope company Eko last week announced it has received FDA 510(k) clearance for an algorithm that detects and characterizes heart murmurs in adult and pediatric patients.  Eko Murmur Analysis Software, which officially received the green light in late June, is a machine learning algorithm that uses heart sounds, phonocardiograms and ECG signals (when available) to detect murmurs and…

This is all the events of the cardiac cycle in one heartbeat (cardiac cycle).

X Axis is time In seconds. You see 2 heartbeats (red circled numbers). -Red line at the top = ventricular pressure -Dashed black line at the top = aortic pressure -Lower dashed black line = atrial pressure -Bottom red line = heart sounds (phonocardiogram) -Blue line = ventricular volume -Yellow line = electrical activity

The “a” is atrial pressure, which increases following the P wave (electrical activity precedes mechanical activity, so after the atria depolarize [P wave], you then get contraction of the atria [a wave]).

AI algorithms developed to detect coronary heart defects

The Food and Drug Administration has given clearance to algorithms for the detection of atrial fibrillation and heart murmurs, when used in combination with a digital stethoscope. Developed by digital health vendor Eko, the company contends that their artificial intelligence-powered stethoscope is the first to screen for these serious cardiovascular conditions and will enable providers to make more accurate patient diagnoses during routine physical exams. According to Connor Landgraf, Eko’s co-founder and CEO, the company’s AI software puts the “ears of a cardiologist” in a clinician’s stethoscope by accurately analyzing electrocardiogram and heart phonocardiogram (heart sound) data. “We interpret those (cardiac data) to identify whether a patient has a murmur in a heart sound or whether they have an arrhythmia in the ECG,” says Landgraf. “What our technology does is allow the clinician to do a very quick screening test in the office that is highly accurate.” When analyzing the one-lead ECG tracing from the Eko DUO stethoscope, the AI is able to detect AFib with 99 percent sensitivity and 97 percent specificity, notes Landgraf. At the same time, he points out that Eko’s AI identifies heart murmurs with 87 percent sensitivity and 87 percent specificity. Northwestern Medicine, which helped Eko to build the algorithms and to test them, served as a clinical study site for the technology. “Two centuries after its invention, the stethoscope is still the front-line tool to detect cardiovascular disease,” says Patrick McCarthy, MD, executive director of the Bluhm Cardiovascular Institute at Northwestern Medicine and a member of the Eko scientific advisory board. “Eko’s development of artificial intelligence algorithms to help clinicians better interpret sounds, identify arrhythmias and detect heart murmurs during a physical exam is going to make a huge difference in our ability to care for patients.” In December, Eko announced that an ECG-based algorithm—developed in collaboration with the Mayo Clinic—was granted “breakthrough device” designation by the FDA and, if cleared by the agency, could offer an easy and accessible screening test for heart failure. The FDA’s voluntary Breakthrough Devices Program—first authorized in late 2016—seeks to preserve the statutory standards for premarket approval, 510(k) clearance and De Novo marketing authorization, while providing timely access to new solutions for treating or diagnosing a disease or condition that have significant advantages over existing treatment or diagnostic alternatives. Going forward, Landgraf says Eko’s AFib and heart murmur algorithms are the first in a suite of cardiac screening algorithms that the company plans to combine with its digital stethoscope. “You can’t beat the traditional stethoscope in terms of its simplicity and ability to quickly determine how a patient’s heart is functioning—and, what we want to do with this digital augmentation is to give clinicians so much more data and insight,” he adds. “We really want to be able to give every frontline clinician the confidence of a cardiologist.” This article has been published from a wire agency feed without modiications to the text.

IIT Bombay: Smart Stethoscope To Hear Heartbeat: Read

IIT Bombay Engineers Creates Smart Stethoscope To Hear Heartbeats From A Distance

The researchers sent 1,000 stethoscopes around the country to various hospitals and clinics.

A group at the Indian Institute of Technology of Bombay (IIT-B) has built up a "savvy stethoscope" that can tune in to pulses from separation and record them, limiting the danger of medicinal services experts getting the novel coronavirus from patients. The information or the auscultated sound from a patient's chest is remotely sent to the specialist utilizing Bluetooth, getting rid of the need to go close to take readings, as per individuals from the group. 

The IIT-B group has gotten a patent for the gadget that records the auscultated sound and stores it as a major aspect of a patient's wellbeing record. This can be imparted to different specialists for examination just as subsequent meet-ups. 

Working a startup called "AyuDevice" from the IIT's innovation business hatchery, the group has sent 1,000 stethoscopes to various emergency clinics and social insurance communities the nation over. The item has been created with clinical contributions from specialists at Reliance Hospital and PD Hinduja Hospital. 

"Patients determined to have coronavirus frequently experience brevity of breath, prompting intense respiratory misery disorder. Specialists use a (conventional) stethoscope to tune in to chest sounds, for example, wheezing and snaps that show up with the advancement of the illness," one of the engineers Adarhsa K said. 

This nonetheless, represents a hazard to specialists, as apparent from the rising contaminations revealed among medicinal services experts taking care of COVID-19 patients, he said. 

Giving insights concerning the computerized stethoscope, Adarsha said it "comprises of a cylinder associated with two earpieces. The cylinder transmits sounds from the body while taking out foundation commotion that may meddle with the conclusion". 

"The subsequent bit of leeway in that the stethoscope can enhance and channel a few sounds and make an interpretation of them into an electronic sign, which can be additionally intensified for ideal tuning in," he said. 

"The sign would then be able to be shown as a phonocardiogram on a cell phone or PC. Interestingly, a standard stethoscope is constrained with regards to enhancing sounds and it is extremely unlikely of recording those sounds and sharing starting with one spot then onto the next. Indeed, even perception is preposterous, which implies one can't see the chart and recognize variations from the norm," he included. 

The loss of life because of the novel coronavirus rose to 239 and the number of cases to 7,447 in the nation on Saturday, as per the Union Health Ministry. 

While the quantity of dynamic COVID-19 cases is 6,565, upwards of 642 individuals were relieved and released and one had relocated, it said.

The Cardio Kinesiograph System

Authored by *

Abstract

The Cardio Kinesiograph System (CKinG) is a novel computerized diagnostic system incorporating a computer model of cardiac kinesis. Cardiac Kinesis (CK) is the interpretation of heart movement or electrical activity of specialized cardiac muscle cells in response to biochemical reactions. The mechanical events occurring during the cardiac cycle consist of changes in pressure in the ventricular chamber which cause(s) blood to move in and out of the ventricle [1]. The events of the cardiac cycle start with an electrical signal and proceed through excitation-contraction coupling (which involves chemical and mechanical events) to contraction of the ventricle (pressure generation) and ejection of blood (flow) into the pulmonary and systemic circulations [2]. Thus, we can characterize the cardiac cycle by tracking changes in ventricular volume (LVV), ventricular pressure (LVP), left atrial pressure (LAP) and aortic pressure (AoP) [3]. In the other hand, because electrical events always precede mechanical events in the cardiac cycle, distortions of a part or parts of the electrical signal have been used as diagnostic indicators of both electrical and mechanical dysfunctions of the heart muscle [4]. There are numerous methods and technical systems available for diagnosis or predict heart disease. However, medical errors and undesirable results [5] in these systems are reasons for a need for conventional computer-based diagnosis of heart diseases systems. The purpose of this study is to design and develop a system that can observe and analyze Kinesiographical Cardiac basted on statistical models and identifies some fundamental characteristic of heart motions.

Keywords: Cardiovascular biomechanics; Statistical analysis methods; Medical heart imaging modalities; DNA modelization in biomedical image

Introduction

Since 1950 cardiologists have studied the functions of heart moments to employ them in the diagnostics of ischemic heart disease (IHD). Indeed, changes of the movements have found their diagnostic application in this field. If blood supply to a certain area of ventricular myocardium is insufficient the con-tractions in this area diminish and even ceases. After systolic increase in ventricular pressure this area dilates and forces intercostal tissues out, causing a “bulge” wave on the record.

Cardiokymography was one of several noninvasive techniques able to detect coronary artery disease. It can qualitatively determine abnormal left ventricular motion, and, based on animal models, this can be directly related to abnormalities in the left coronary artery [7]. Nevertheless sensitivity of cardiokymography in detecting patients with ischaemic left ventricular wall motion abnormalities depended on the extent of left ventricular ischaemia [8]. Cardiokymography is no longer valid [9]. Today Computer Aided Diagnosis (CAD) is one of the trusted methods in the field of medicine [10]. Advances in medical imaging and image processing techniques have greatly enhanced interpretation of medical images. Computer aided diagnosis (CAD) systems based on these techniques play a vital role [11] in the early detection of cardiovascular diseases and hence reduce death rate. CAD is the most preferable method for the initial diagnosis of heart disease. The combination of Digital and Medical Image Pro-cessing, Cardiac Electrophysiology, Ventricular Pressure-Volume Technique and Phonocardiogram etc makes the CAD system more reliable and efficient. One example of the medical applications in computer aided diagnosis is the detection system for heart disease based on Cardiovascular Magnetic Resonance (CMR). Cardiovascular magnetic resonance of the heart provides a potentially useful way to assess cardiac mechanical function. Besides CMR, positron emission tomography (PET), and cardiac CT are able to illustrate kinesis of cardiac muscles. Perfusion imaging with cardiac PET is used clinically to produce images of myocardial blood flow, aiding the diagnosis of coronary artery disease and the monitoring of condition of coronary circulation in response to treatment [12].

Clinical imaging in positron emission tomography (PET) is often performed using single-time-point estimates of tracer uptake or static imaging that provides a spatial map of regional tracer concentration [13]. However, dynamic cardiac techniques (e.g. PET, Myocardial perfusion imaging and Dynamic cardiac SPECT [14]) are used to estimate rate parameters activity of myocardial blood flow, and there are limited studies evaluating the role of Cardiovascular Magnetic Resonance and cardiac PET and cardiac CT for the assessment of cardiac kinesis. Therefore, scientific communities in computational cardiovascular science [15] have contributed to developing mathematical models and algorithms to improve efficiency of cardiac safety data management in clinical trials. In this way in 2014 proposed a new method based on a mathematical model, “Fourier Transform” which calculates an amplitude parametric image for the assessment of cardiac kinetics. This image, calculated from the Cine MR images, allows the localization and quantification of abnormalities related to difference in contraction and their extent [16]. In 2015 Zakynthinaki [17] has also presented effective mathematical model of heart rate kinetics in response to movement. She made conclusion that the new model is able not only to provide important information regarding an individual’s cardiovascular condition but to also simulate and predict heart rate kinetics for any given exercise intensities. The existing models of cardiac kinetics focus mainly on amplitude images or are limited to simulation of biological transformation. The present study provides a novel mathematical model of cardiac kinesis based on visual presentation of numerical data (obtained through the cardiac kinesis) in the form of graph, with a particular focus on Human Cardio Kinesiograph Analysis. The purpose of this study was to de-sign, develop and evaluate a novel method for Kinesiograph of Cardiac for the clinical assessment of cardiac and vascular function.

Methods and Materials

The system includes the following steps:

Data collection: In order to obtain an accurate data, the Cardiovascular Magnetic Resonance imaging (CMR), Cardiovascular Ultrasound or Cardiac Computed Tomography are produced better performances for detection of cardiac mobility. However, CMR is provided the most comprehensive anatomic picture for patient selection [18]. The system therefore is obtained relevant information from the CMR.

Video quality assessment: Different medical imaging methods may introduce common artifacts include image distortion, signal pileup (bright regions), and image dropout (area without signal) [19], therefore the quality assessment is an important factor at the operational level. The assessment of quality of video depends upon the type of distortion [20]. Numerous video quality assessment methods and metrics have been proposed over the past years with varying computational complexity and accuracy [21]. We utilize different forms of quality assessment methods, however the merit of these methods is often judged by assessing the quality of a set of results through lengthy user studies [22].

Motion estimation and inertial measurements: Motion estimation is the process of determining the movement of blocks between adjacent video frames (MathWorks). Efficient and accurate motion estimation is an essential component in the domains of image sequence analysis [23] and medical video processing. The estimation of motion is also important from the viewpoint of matching metric technique, which is computed the context similarity between two images. There exist several methods for motion estimation image, and video processing (e.g. pixel-based motion estimation, block-based motion estimation, optical flow method). In this study in order to increase the computational accuracy and improve efficiency in solving problem, DNA Modeling (Dawoudi, 2017) method in biomedical image matching has been proposed. The method is based on the linear mapping and the one-to-one correspondences between point features extracted from the frames and on calculating similarities in pixel values. This correspondence is determined by comparing two strings constructed from pixel values of the frames. The method uses a table called the Quarter Code table, which is the set of characters and numbers. In this table every number between 0 and 255 is translated into a unique string of four letter alphabet. Letters A,C,G,T are chosen, since they are the same as used in DNA sequences. In this way it possible to utilize tools originally programmed to DNA sequences analysis. When all pixel values of the frames (images) are converted to virtual DNA sequences, one can show the differences between two virtual DNA sequences.

Visual representation of numerical data in the form of graphs: The E-value gives a measure of the similarity of sequences. From this function we can obtain the correlation coefficient which will give us a single value of similarity. The rate of similarity between sequences (frames) is plotted as a graph and it’s appearing in the Monitor.

Experiment Results

We demonstrate the system by performing experiment 2D cardiac CMR video (Source: HBSNS library). The practical framework consists of four steps:

A. Step 1: Extract frames from cardiac mri video

The information is obtained by extracting frames from CMR imaging video. There are different tools in order to extract frames from cardiac MRI Video (e.g. Free Video to JPG Converter, VLC or Virtual Dud) (Figure 1).

B. Step 2: Adjacent frames comparisons

The difference between two adjacent frames is used to estimate motion direction and magnitude. This process has been implemented within a tool called Image Diff. The Perforce image diff tool enables researchers to compare two adjacent frames. The following represents pixels difference value (Percent Changed; Pixels) and color difference value (Percent Change; Color) between adjacent Frames (Table 1).

C. Step 3: Presenting data in graphic form

In the final step the percentage of change (pixels and color) from one value to another, between frames are plotted as a graph (Figure 2 & 3).

Results

The results show that the proposed design approach works efficiently in the Cardio Kinesis System for clinical applications of cardiovascular assessment.

Conclusion

In conclusion, the proposed Cardio Kinesiograph System (CKinG) may become a robust and efficient tool for the clinical assessment of Cardiac and Vascular function. CKinGbased Computer-Aided Diagnosis (CAD) holds the promise of improving the diagnosis accuracy and reducing the cost.

Discussion

The developed system can be used as a prototype in the clinical sectors for the evaluation of cardiovascular diseases. However, a novel method for real time MRI of cardiac kinesis and simultaneously Kinesiographical Cardiac Analysis Based on Statistical Methods are proposed. The proposed methods may become efficient Medical Diagnostic Support tools (DSTs) for Heart Diseases.

HOW DOES TECHNOLOGY AFFECTS THE FIELD OF MEDICINE

The continuous advancement of Medical Technology aids for the demand for the innovative health care of humanity worldwide. The newly develop technology is being improved everyday for a more effective health treatment for the people. Lots of alternative treatments are now available for either public and private hospital because of medical science. In addition to that, medical devices that have an advanced feature to cure or identify any kinds of ailments and diseases are created for the betterment of people's well-being. And all of that is made possible because of the successful development of technology in the medical field.

The availability of advance technology diagnosis has been a big help in increasing the life span of the people. Here are some of the good examples of tech products that contributes to the big changes on the treatment and prevention of a disease over time: medical and surgical procedures (angioplasty, joint replacements); drugs (biologic agents); medical devices (CT scanners, implantable defibrillators); and new support systems (electronic medical records and transmission of information, telemedicine). In the medical field there has been a more detailed understanding of the origin of disease, the different parts of the body and its function. By such learning, diseases that are incurable before can be detected beforehand, even before the symptoms became visible, thus the worsening of one's condition can be prevented by giving proper medication. Even ailments that do not show even one symptom can be detected early enough before the body deteriorates, hence diseases are fairly combated.

According to the Department of Health, heart problems are one of the leading causes of human mortality in the Philippines. In milder cases, the patient should be checked frequently by its own physician. But in more serious cases, consulting a heart specialist is necessary. But with the aid of our modern medical technology, many diagnoses and treatments can be done to help people who are suffering from different types of diseases. Based on the book written by Anderson, "much of the largest medical center today has highly trained teams of specialists that are now improving newer and more wonderful ways of studying treatments for damaged heart like heart catheterization". Differential diagnosis is also done to better understand how such heart diseases can be solved. Firsts is Angiocardiography also known as arteriography, this is a method by which vital blood vessels can be viewed under x-ray. Second is Orthocardiography, this is the method used in outlining the size and shape of the heart by means of special x-ray. Pictures taken can show either the chambers of the heart are enlarged or not. Third is the Vectocardiogram, it is the method of studying and evaluating the electric activity of the heart. It gives a better and clearer image comparable to an electrocardiograph. Lastly, the Phonocardiogram, a special device that measures the actual sound of the heart as can be heard through a stethoscope. This instrument is important in dealing certain obscure heart condition.

So much for that, different machines and medicines are available in the market for the people. The better diagnosis, better prevention and better treatments for the high standard health care of patients are now possible thanks to our newly developed technology in the medical field. Though the effect of technology to the field of medicine was great, its affordability to the mass of people is questionable still. Because the cost of most of the treatments is relatively high. But we can't deny the fact that technology and medicine are indeed inflexibly intertwined. Let's just see in the future how can technology greatly affect the advancement of medicine worldwide.
