Newborns with heart complications can rely on their newly developed immune systems to regenerate cardiac tissues, but adults aren’t so lucky. After a heart attack, most adults struggle to regenerate healthy heart tissue, leading to scar-tissue buildup and, often, heart failure.
A new Northwestern Medicine study in experimental animals reveals a critical difference in how macrophages — a part of the immune system — help repair the heart in newborns versus adults after a heart attack. The study highlights a fundamental difference in how the immune system drives healing based on age.
Patients aged between 50 to 70 years with a mechanical heart valve replacement had better long-term survival compared to those with a biological valve, new research led by the University of Bristol has found. The study is published in the European Journal of Cardio-Thoracic Surgery.
Researchers at Washington University in St. Louis have developed a method that leverages artificial intelligence to ensure accurate heart scans without added radiation or cost
In patients with symptoms such as irregular heartbeats, dizziness, or fainting, or in individuals that physicians suspect may have atrial fibrillation, many days of ECGs may be required for diagnosis – “long-term ECG recordings”. These recordings must then undergo a time-consuming and human resource-intensive review to identify heart rhythm abnormalities. In a large international study, researchers tested whether an AI model can replace humans in analyzing long-term ECG recordings. The results: 14 times fewer missed diagnoses by the AI.
