One of the most common symptoms of heart failure is shortness of breath caused by fluid build-up in the lungs. A potentially life-saving application was developed with this in mind, because it can analyze users’ voices to see if they have lung congestion associated with heart failure. The experimental app was created by Israeli start-up Cordio Medical called Cordio HearO. It was recently evaluated in a study led by Professor Offer Amir, director of the Heart Institute at Hadassah Medical Center in Jerusalem. He is also a consultant to Cordio Medical.
The study involved 40 patients hospitalized with acute heart failure and pulmonary congestion. Each person uses the app to record 5 spoken words when admitted to the hospital, and then again before they are discharged when their condition improves and they do not fill up. It turns out that for everyone, the application is very accurate in distinguishing between pulmonary congestion and pulmonary congestion.
It is now hoped that Cordio HearO, an app, will be available to patients at risk of heart failure, who will make a baseline record in their own home and when they are healthy.
They will then record on a daily basis and compare it with the baseline. They and their doctors will be notified if the app determines that their lungs are beginning to accumulate fluid. This makes it possible to address their condition by changing the medication before they need to be admitted to hospital.
Scientists at Singapore’s Chen Dusheng Hospital and Nanyang Technological University have recently followed suit, but have developed an acoustic sensor that resembles a stethoscope that patients can plug into a smartphone and perform a lung congestion check at home.
The results of Amir’s team were recently published on the European Society of Cardiology’s HFA Discoveries online platform.
