Board-certified cardiothoracic surgeon Dr. Jeremy London, based in Savannah, Georgia, explains why VO2 max and muscle mass are the main indicators of longevity. The first artificial intelligence (AI) stethoscope has gone beyond listening to a heartbeat. Researchers at Imperial College London and Imperial College Healthcare NHS Trust discovered that an AI stethoscope can detect heart failure at an early stage. The TRICORDER study results, published in BMJ Journals, found that the AI-enabled stethoscope can help doctors identify three heart conditions in just 15 seconds. According to the British Heart Foundation (BHF), which partially funded the study, the researchers analyzed data from more than 1.5 million patients, focusing on people with heart failure symptoms like breathlessness, swelling and fatigue.

Doctors have successfully developed an artificial intelligence-led stethoscope that can detect three heart conditions in 15 seconds. Invented in 1816, the traditional stethoscope – used to listen to sounds within the body – has been a vital part of every medic's toolkit for more than two centuries. Now a team have designed a hi-tech upgrade with AI capabilities that can diagnose heart failure, heart valve disease and abnormal heart rhythms almost instantly. The new stethoscope developed by researchers at Imperial College London and Imperial College healthcare NHS trust can analyse tiny differences in heartbeat and blood flow undetectable to the human ear, and take a rapid ECG at the same time. Details of the breakthrough, which could boost early diagnosis of the three conditions, were presented to thousands of doctors at the European Society of Cardiology annual congress in Madrid, the world's largest heart conference.

Scientists have invented the gadget to be able to spot warning signs - without the need for a doctor's trained ear. Using noise-filtering technology and an understanding of what lungs with pneumonia sound like, the stethoscope could save lives, its developers say. The Feelix and FeelixPro stethoscopes will be launched this year and scientists say it correctly identifies the disease almost nine times out of 10. Developed by experts from Johns Hopkins University in Baltimore, Maryland, the stethoscope is believed to be 87 per cent accurate at diagnosing the lung disease. Pneumonia, which causes the lungs to fill with fluid, kills almost one million children under the age of five globally each year.
