Gut microbes may reveal why diabetes raises heart disease risk

Integrated gut microbiome and plasma metabolomics profiling identified distinct microbial and metabolic signatures in people with T2DM and T2DM-CAD. In a small exploratory cohort, Bacteroides sp._CAG_875 and 12-ketoLCA emerged as candidate markers that may help distinguish diabetic patients with coronary complications, pending larger validation.

AI models predict sudden cardiac arrest risk using health records

Researchers have developed artificial intelligence (AI) models that can scrutinize electronic health records (EHR) and electrocardiograms to identify individuals in the general population at elevated risk for sudden cardiac arrest - a condition that causes more than 400,000 U.S. deaths annually and has a survival rate of only 10%.
