This cardiac catheter uses light and ultrasound to measure plaques

Researchers at the University of California at Davis combined ultrasound with light into a catheter probe to view the tiny arteries of the heart. The device uses intravascular ultrasound and fluorescence lifetime imaging (FLIm) to retrieve structural and biochemical information about plaque in the arteries to help predict heart attacks more reliably, according to the

Artificial intelligence accurately predicts stroke risk

Machine-learning algorithms, a form of artificial intelligence, accurately predicted people’s risk of heart disease and stroke, according to new research from the University of Nottingham. Researchers and computer scientists compared the risk guidelines for heart disease and stroke from the American College of Cardiology with 4 machine-learning algorithms to analyze the risk of a patient

9 cardiology breakthroughs you need to know

Cardiology breakthroughs couldn’t come soon enough because heart disease is the No. 1 killer of men and women in the U.S. About 610,000 Americans die of heart disease per year, and an additional 735,000 Americans suffer from a heart attack. The statistics terrify. High blood pressure, high cholesterol and smoking are some of the top

Growing heart muscle cells: 2 breakthroughs you need to know

Host animal hearts and 3-D printed scaffolds—both appear to be showing promise when it comes to growing heart tissue to restore damaged hearts. Researchers at Johns Hopkins University recently reported that they’ve had success using host animal hearts to grow mature and viable heart muscle cells from stem cells. Meanwhile, a 1-micron-resolution scaffold made with a 3-D printer
