A recent study using mice has revealed a way to turn back the clock after heart attack. The researchers behind the work used RNAs to instruct cells in an injured heart to eliminate scar tissue and recreate cardiac muscle, allowing the heart to function like new again.
1. This retrospective study found that in patients presenting to the emergency department with acute dyspnea, elevated high-sensitivity cardiac troponin T (hs-cTnT) was associated with a higher 3-month all-cause mortality than those without an elevated hs-cTnT level. 2. Patients presenting with acute dyspnea along with an elevated hs-cTnT were older, more frequently male, more often
The device, a wrist-worn sensor that uses infrared light to detect the presence and concentration of cardiac troponin-I in the blood through the skin, predicted levels with 90% accuracy within 5 minutes.
