The electrical activity in the human heart can be measured as a sequence of amplitudes away from a baseline signal. The segmentation of these regions of ECG waveforms can provide the basis for measurements useful for assessing the overall health of the human heart and the presence of abnormalities . Manually annotating each region of the ECG signal can be a tedious and time-consuming task. Signal processing and deep learning methods potentially can help streamline and automate region-of-interest annotation. This example uses ECG signals from the publicly available QT Database  .
Eating a small bowl of cranberries every day could help ward off dementia, research suggested today. Scientists tested giving healthy older adults the equivalent of 100g of the fruit each day. Volunteers who ate a powdered version of the fruit -- which has a notoriously bitter taste -- were found to have a better memory recall after 12 weeks. And MRI scans showed those eating cranberries had better blood flow to important parts of the brain. People given cranberries also had 9 per cent lower bad cholesterol levels, according to the University of East Anglia study.
Cardiovascular Disease has long been the number one cause of death in the U.S. and some of the stats are startling: an American will have a heart attack approximately every 40 seconds for a total of 805,000 every year, At the same time, mortality and morbidity rates of CVD are increasing year by year, especially in developing regions. Studies have shown that approximately 80% of CVD-related deaths occur in low- and middle-income countries. Besides, these deaths occur at a younger age than in high-income countries. CVD represents a significant economic cost for society, around $351.2 billion in the US, chronically affecting patients' quality of life. The EU has estimated that the overall yearly cost amounts to €210 billion, allocating around 53% to healthcare costs (€111 billion), with 26% related to productivity losses (€54 billion), and the remaining 21% (€45 billion) to the informal care of people with CVD (European Cardiovascular Disease Statistics 2017).
Researchers at Johns Hopkins University developed artificial intelligence technology that may be able to assess a patient's risk of sudden cardiac death, which is when the heart abruptly stops beating. Sometimes, modern medicine isn't enough to help keep us healthy. The Johns Hopkins University researchers said artificial intelligence can help accurately predict if and when someone's heart will stop beating years in advance. "It uses deep learning on images in combination with deep learning also on clinical data to predict the patient's risk of sudden cardiac death over a period of 10 years," said Dr. Natalia Trayanova, a professor of biomedical engineering and medicine. Trayanova's team developed the AI technology and published their work in a medical journal.
Royal Papworth Hospital NHS Foundation Trust is leading a study into the use of artificial intelligence (AI) to diagnose heart valve disease. Royal Papworth is working with the University of Cambridge on the research, which hopes to develop a screening tool powered by AI to help diagnose the disease before symptoms are first displayed. The research will involve thousands of patients having four heart recordings that are collected via a Bluetooth stethoscope, in addition to the conventional route of an echocardiogram. Recordings will be uploaded to a machine-learning programme, so that the University of Cambridge can build an audio database of the noises associated with heart valve diseases. Ultimately, the research aims to create an artificially intelligent stethoscope that can analyse heart murmurs to provide either a diagnosis or determine if further investigation is needed.
Ailing healthcare systems around the world are under the spotlight and the need for universal access to quality healthcare has never been greater as many factors continue to put pressure on the sector. These include ageing populations, clinical workforce challenges, rising utilisation stemming from a growing burden of chronic diseases like cancer, diabetes and cardiovascular disease (CVD), and reimbursement-related challenges. Reassuringly, the pandemic has forced governments to reconsider every aspect of their healthcare systems. For example, workforce size and shape, digital infrastructure, models of care focusing on primary-care pathways and digitally enabled interventions and disease surveillance, research, supply chain speed and resilience, access to care, data use, regulation, and service integration. In the UAE, health spending grew from Dh45 billion in 2016 to Dh61.7 billion in 2020.
MARSEILLE, France and PROVIDENCE, R.I., April 27, 2022 (GLOBE NEWSWIRE) -- Volta Medical, a pioneering medtech startup advancing novel artificial intelligence (AI) algorithms to treat cardiac arrhythmias, today announced it will participate at Heart Rhythm 2022, where Volta VX1 digital AI companion technology will be featured in several venues, including a poster session, podium presentation, Rhythm Theater program and the Volta exhibit booth. VX1 is a machine and deep learning-based algorithm designed to assist operators in the real-time manual annotation of 3D anatomical and electrical maps of the human atria during atrial fibrillation (AF) or atrial tachycardia. It is the first FDA cleared AI-based tool in interventional cardiac electrophysiology (EP). On Friday, April 29, VX1 will be highlighted in two scientific sessions: session DH-202, "Machine Learning Applications for Arrhythmia Detection and Treatment" from 10:30-11:30 a.m. Volta's Rhythm Theater presentation, "Can AI Solve the Persistent AF Paradigm?," will be held Saturday, April 30 from 10:00-11:00 a.m.
A new form of artificial intelligence may be able to predict with more accuracy than a doctor if and when a person will die from cardiac arrest. In a new studyTrusted Source, researchers from Johns Hopkins University in Maryland say artificial intelligence (AI) called Survival Study of Cardiac Arrhythmia Risk (SSCAR) might revolutionize how clinical decisions are made in the field of cardiology. "Sudden cardiac death caused by arrhythmia accounts for as many as 20 percent of all deaths worldwide, and we know little about why it's happening or how to tell who's at risk," Natalia A. Trayanova, Ph.D., a senior author of the study and a professor of biomedical engineering and medicine at Johns Hopkins, said in a press release.
