Machine learning-based early detection of abnormal heart rate in critically ill patients: a real-world clinical dataset study with automated alert system integration

Introduction Cardiovascular diseases (CVD) are a leading global health challenge, particularly in resource-constrained settings where delayed diagnosis worsens outcomes. Abnormal heart rate (tachycardia/bradycardia) is a modifiable, independent risk factor that benefits from early, automated detection. Methods We used...

Artificial intelligence–based calcium scoring using 3D transesophageal echocardiography in aortic stenosis: a pilot study

AI-based calcium quantification using 3D TEE is feasible and correlates with CT-derived scores, and this radiation-free approach may provide a promising alternative for assessing aortic valve calcification.
